step 1: a monitoring device is arranged on the solid-phase arc extinguishing device 103, the solid-phase arc extinguishing device 103 is arranged on a tower, and a repeater device is arranged in an electrical equipment box below the tower. One repeater unit is wirelessly connected to several monitoring units 103, the repeater unit being wirelessly connected to remote clients and/or servers.

An arc striking rod 102 is arranged on the solid-phase arc extinguishing device 103, the arc striking rod 102 is vertically arranged on the solid-phase arc extinguishing device 103, and the bottom end of the arc striking rod 102 is connected into an arc extinguishing cylinder of the solid-phase arc extinguishing device 103 and is triggered.

The solid-phase arc extinguishing device 103 is further provided with a preionization module 104, a trigger magnetic field induction coil is arranged outside the preionization module 104 and is connected with the preionization module 104, when thundercloud approaches a power transmission line, the thundercloud generates downlink pilot, field intensity changes, the trigger magnetic field induction coil induces field intensity change and transmits a field intensity change signal to the preionization module 104, after the preionization module 104 receives the field intensity change signal, the preionization module is activated to generate early discharge pulses, the discharge pulses ionize air electrons, free electrons are generated around the arc ignition rod 102, and the arc ignition rod 102 absorbs lightning arcs.

The monitoring device comprises a solid-phase detection probe 105, a monitoring control module 106 and a detection transmitting antenna 107, wherein the solid-phase detection probe 105 is arranged on the solid-phase arc extinguishing device 103 and is connected with the monitoring control module 106, the detection transmitting antenna 107 is connected with the monitoring control module 106 and is in wireless connection with the repeater device, the solid-phase detection probe 105 is used for detecting the size data of the lightning arc on the arc striking rod 102, detecting the size data of the trigger current of the solid-phase arc, detecting the number of times of successful triggering of the solid-phase arc extinguishing device 103 and the state condition data of the solid-phase arc extinguishing device 103 and transmitting the data to the monitoring control module 106, the monitoring control module 106 packs the detected data and the acquired time tag and transmits the data to the repeater device through the detection transmitting antenna 107, and the solid-phase detection probe 105 and the monitoring control module. The relay device comprises a relay receiving antenna 108, a relay control module 109 and a relay transmitting antenna 110, wherein the relay receiving antenna 108 is in wireless connection with the detection transmitting antenna 107, and the relay control module 109 transmits data received by the relay receiving antenna 108 to a server or a remote client through the relay transmitting antenna 110.

Firstly, the monitoring device is arranged on the solid phase device, and the main module is independently arranged in an electrical equipment box below the tower.

After the monitoring device is powered on and started, the global positioning data of the corresponding position is automatically collected, and the global positioning data is stored locally after the collection is completed.

Step 2: when a lightning arc is introduced into the solid-phase arc extinguishing device 103, the monitoring device collects lightning arc data, state data of the solid-phase arc extinguishing device 103, trigger current and positioning data of the solid-phase arc extinguishing device 103, and sends the lightning arc data, the state data, the trigger current and the positioning data to the repeater device by marking time. The state data of the solid-phase arc extinguishing device 103 comprises the number of times that the solid-phase arc extinguishing device 103 is triggered and the current of the corresponding trigger end of each trigger, and the trigger current is the current of the lightning arc. If the overvoltage generated on the circuit is detected, the pre-discharge function is started first, and the electric arc is guided to enter the solid-phase arc striking rod.

If the electric arc enters the arc striking rod and the solid phase device is triggered, the continuous triggering times and the instantaneous triggering current are automatically recorded, and data such as global positioning coordinates, triggering current, total triggering success times, continuous triggering times, device states and the like during triggering are sent.

If the arc enters the arc striking rod but the device is not triggered, the device automatically records the triggering failure, and immediately sends data such as global positioning coordinates, triggering current, triggering failure times, device state and the like when the triggering failure occurs.

And (4) counting the total triggering times of the single solid-phase device, namely counting the real-time total triggering times of the solid-phase device after the monitoring device is started. The number of continuous triggering times of a single solid phase device is counted, namely the number of times that the solid phase device is triggered for multiple times within a period of time (which can be set manually). Counting the triggering failure times of the single solid phase device, namely counting the times that the arc striking rod receives the overvoltage signal within a period of time (which can be set manually), but the triggering failure times are also sent to the main module when the solid phase device is not triggered. The global positioning coordinates of the individual solid phase devices are collected so that the monitor knows the location of the triggered solid phase device. At the instant of triggering the solid phase device, the monitoring device can collect the triggering current value, and if the solid phase device is continuously triggered for multiple times, the current data triggered at the last time is taken and sent to the main module.

If the solid phase device is damaged, the monitoring device marks the solid phase device as an abnormal state and automatically sends the abnormal state to the main module.

The automatic reset function, because monitoring devices belong to weak current equipment, in the actual monitoring process, can be inevitable suffer from high strength electromagnetic interference or other unexpected circumstances. Therefore, an automatic reset program is arranged in the control program, and when the chip runs incorrectly, the monitoring device and the main module are automatically reset. Therefore, the reliability of the monitoring system can be fundamentally improved without human intervention. Once the device is reset, the total trigger count value is reset to zero and the global positioning data is retrieved.

And step 3: and after receiving the data transmitted by the monitoring device, the repeater device packages and transmits the data to the server or the remote client. The remote client can be a mobile phone or a tablet computer, and the server can be a cloud server and the like.

The air pill base 13A and the air pill 14A are nested within the envelope 12A, which envelopes them. And the tight nesting of the air pill base 13A and the air pill 14A with the coating layer 12A is realized, and the thickness of the inner wall of the coating layer 2 can be processed, so that the air pill base and the air pill do not deviate or expand and the like. The gas bolus 14A is held at a high gas pressure by the envelope 12A, and all of the gas generated by the combustion of the gas generating material in the gas bolus 14A is subjected to all of the pressure in the envelope 12A. A trigger signal input port is designed at the top end of the wrapping layer 12A, and a trigger signal input terminal 11A is arranged on the trigger signal input port and used for receiving a lightning trigger signal by the air ball 14A; the fumarole 15A that parcel layer 12A established, gaseous 15A blowout and the spray direction from this fumarole that does not wrap up are controllable, diminish through the aperture of the fumarole 15A who establishes, and the position that sets up as required simultaneously realizes having realized the controllable condition of direction with the contrast of original detonation mode. The wrapping layer 12A is made of a high-strength material such as aluminum steel.

After the gas pill 14A receives the trigger signal input by the trigger signal input terminal 1, gas is rapidly generated in the gas pill 14A, and the strength of the wrapping layer 12A is very good and is far greater than the pressure of the gas generated by the gas pill 14A, so that the wrapping layer 12A cannot crack to generate detonation. The pressure intensity of the gas generated in the gas pill 4 is greater than the surface layer of the gas pill 4, and after the gas pill bears the maximum pressure, the gas generated by the gas pill 4 can only be ejected from the gas ejecting hole 15A, so that the pressure intensity of the ejected gas is increased, and the operation of controllable gas ejecting direction is realized according to the setting size and position of the gas ejecting hole 15A. And during the burning process of the gas pill 14A, the internal gas pressure is increased, so that the burning speed is higher, and the arc extinguishing reaction time is shorter.

The air ejection holes 15A are provided at opposite ends of the trigger signal input terminal 11A, and the trigger signal input terminal 11A is provided in contact with the gas pill 14A. Through setting up fumarole 15A and trigger signal input terminal 11A at the opposition end for gunpowder in the gas pellet 14A structure just can press the material constraint layer of fumarole 5 in the twinkling of an eye after the complete burning of gas pressure, makes the gas production material burning in the gas pellet 14A more complete, and gas pressure is bigger, can extinguish the electric arc that higher voltage transmission of electricity produced, makes the effect of arc extinguishing better.

The gas pill 14A comprises a material bound layer, gunpowder and solid oxygen or liquid oxygen, wherein the gunpowder and the solid oxygen or the liquid oxygen are mixed and sealed and placed in the material bound layer, and the increment pressure of the material bound layer is less than the critical pressure of the gunpowder fracture.

After the gunpowder is ignited, the solid oxygen or the liquid oxygen provides combustion oxygen, and when the temperature rises, the solid oxygen or the liquid oxygen is gasified to provide an additional gas pressure, so that a secondary pressurization effect is formed, and the gas pressure is increased more quickly. The gas pressure generated when the gunpowder is burnt basically and completely is larger than the critical pressure for the rupture of the material bound layer, so that the material bound layer at the gas injection hole 5 is ruptured, and the gas is injected from the gas injection hole 5 for arc extinction.

The trigger signal input terminal 11A is arranged by arranging a plurality of heating resistance wires in contact with gunpowder inside the gas pill, and the plurality of heating resistance wires are arranged in parallel and connected with the trigger signal input terminal. The heating resistance wires are arranged in parallel, so that the effect of multipoint ignition is realized, the reaction time can be shortened, the reaction time for arc extinction can be shortened, and the arc extinction is quicker.

The trigger signal input terminal 11A inputs a current signal, the resistance wire generates heat, gunpowder in the gas pill burns to generate high-pressure gas, the wrapping layer 12A axially and radially restrains the high-pressure gas, the pressure of the high-pressure gas is greater than the bending moment of the material binding layer at the gas jet hole, the high-pressure gas is jetted out from the gas jet hole, and the gas jet direction is controlled by the position of the gas jet hole 15A. When the gas pill 4 receives the electric signal of the trigger signal input terminal 1, a large amount of arc extinguishing gas can be triggered and generated; the high-strength wrapping layer 12A carries out radial restraint and axial restraint on the air flow, and the incremental pressure in the wrapping layer 12A is rapidly increased; because the strength of the air outlet is far less than that of the wrapping layer 12A, and the aperture of the air injection hole 15A is reduced, a large bending moment can be generated, when the sum of the basic pressure of the air pill 14A and the increment pressure of the wrapping layer is greater than the critical pressure of the rupture of the gas generating material, the air flow is injected from the non-wrapped air outlet, the injection direction of the air outlet is controllable, the injected air flow is concentrated and strong, and the arc extinguishing effect is greatly improved. By improving the sealing strength, the material in the gas pill 14A is fully combusted to generate larger critical release air pressure, high-speed arc extinguishing airflow is generated while arc is built, the high-speed arc extinguishing airflow acts on an arc channel, the follow-up power frequency arc building process is blocked, the power frequency arc can be extinguished in a very short time, and the arc extinguishing time is far shorter than the action time of the circuit breaker.

After the gas pill base 13A and the gas pill 14A are sleeved, the buckling cover is covered, then the buckle is used for buckling, the installation is convenient, the installation can be completed directly by hand, the processing speed is high, and the economy is less than high.

The size of the gas injection hole 15A is 5-8mm, and the gas generated by the gas pill 14A is ejected from the gas injection hole. The air current is sprayed from the uncoated air injection hole 15A, the spraying direction of the air injection hole 15A is controllable, the sprayed air current is concentrated and strong, and the arc extinguishing effect is greatly improved. The ordinary original spray hole is generally dozens of millimeters, so that the spray range is too large, the spray time is shortened, and the arc extinguishing effect is poor. According to a bending moment calculation formula: m is θ gEI/L, θ is torque, EI is rotational stiffness, and L is the effective calculated length of the rod. Theta is that torque and EI are the rotational stiffness homogeneous phase is the same, and L shortens the back for the moment of flexure grow, and the pressure grow of spun gas promptly, and fumarole 16A is less, and same gas needs longer time just can spout, and the time of arc extinguishing also is longer, reaches the increase of arc extinguishing gas pressure, and the arc extinguishing time increases, reaches the effect of better arc extinguishing.

The wrapping layer 12A and the material binding layer are made of the same type of metal materials, and the thickness of the wrapping layer 12A is in direct proportion to the amount of gunpowder. Because the lightning protection device is installed on the transmission line for a long time, the conditions of sun exposure and rain exposure can be caused, if different metals are used, a point potential difference is formed between the material binding layer and the radial sleeve piece or the wrapping layer, and the condition of corrosion can easily occur after the potential difference is formed, so that the service life of the lightning protection device is greatly shortened, and the same type of metal materials can be used for effectively preventing the conditions.

After the gas pill 15C receives the trigger signal input by the trigger signal input terminal 11C, gas is rapidly generated in the gas pill 15C, and the sleeve 13C and the limiting barrel 12C are prevented from being broken to generate detonation conditions because the strength of the sleeve 13C and the limiting barrel 12C is very good and is far greater than the pressure of the gas generated by the gas pill 15C. After the pressure intensity of the gas generated in the gas pill 15C is greater than the maximum bearing pressure of the surface layer of the gas pill 5, the gas generated by the gas pill 15C can only be ejected from the gas ejecting hole 16C, so that the pressure intensity of the ejected gas is increased, and meanwhile, the operation of controllable gas ejecting direction is realized according to the setting size and the position of the gas ejecting hole C16. And in the burning process of the gas pill 15C, the internal gas pressure is increased, so that the burning speed is higher, and the arc extinguishing reaction time is shorter.

As shown in fig. 11, the pressurized balloon 3 includes a trigger signal input terminal 11D, an upper frame 12D, a sleeve 13D, a balloon seat 14D, a balloon 15D, a lower frame 16D, and an air vent 17D, the trigger signal input terminal 11D is arranged on an air pill base 14D, the air pill base 14D is connected with an air pill 15D, the sleeve 13D is sleeved on the outer side of the balloon 15D, the upper frame body 12D is detachably connected with the lower frame body 16D, and the upper frame body 12D and the lower frame body 16D are clamped and sleeved on the outer sides of the sleeve 13D and the balloon base 14D, the air injection holes 17D are arranged on the lower frame body 16D, the sum of the base pressure of the gas pill 15D and the increment pressure of the upper frame body 12D and the lower frame body 16D and/or the increment pressure of the sleeve 13D is larger than the critical pressure of the gas generating material in the gas pill 15D to break, the upper frame 12D, the lower frame 16D, and the sleeve 13D are all formed of a hard structure.

The airpills 15D are nested in the sleeve 13D, the sleeve 13D wraps the side edge of the airpills 15D, the inner side of the top end of the upper frame body 12D is in close contact with the airpill base 14D, and the inner side of the lower frame body 16D is in close contact with the bottom of the airpills 15D or the bottom of the sleeve 13D. The sleeve 13D radially and tightly nests and wraps the balloon 15D, and the thickness of the inner wall of the sleeve 13D is treated so that the balloon does not deflect or expand and the like. The large gas pressure of the gas pill 15D is confined by the sleeve 13D, and all the gas generated by the combustion of the gas-generating material in the gas pill 15D is subjected to all the pressures in the sleeve 13D. The upper frame body 12D and the lower frame body 16D limit the upper and lower ends of the high-pressure gas generated in the gas pill 15D in the vertical direction, so that the upper and lower ends do not expand or burst. The top of the upper frame body 12D is provided with a trigger signal input port, and a trigger signal input terminal 11D is arranged on the trigger signal input port and used for receiving a lightning trigger signal by the air ball 15D. The fumarole 17D that framework 16D was equipped with down, gaseous 17D blowout and the injection direction of this fumarole of not wrapping up of following is controllable, and the aperture through the fumarole 17D who establishes diminishes, and the position that sets up as required simultaneously realizes having realized the controllable condition of direction with the contrast of original detonation mode. The limiting barrel 12D and the sleeve 13D are made of high-strength materials such as aluminum steel.

After the gas pill 15D receives the trigger signal input by the trigger signal input terminal 11D, gas is rapidly generated in the gas pill 15D, and the sleeve 13D, the upper frame 12D and the lower frame 16D have good strength and are far greater than the pressure of the gas generated by the gas pill 15D, so that the sleeve 13D, the upper frame 12D and the lower frame 16D cannot crack to generate detonation. After the pressure intensity of the gas generated in the gas pill 15D is greater than the maximum bearing pressure of the surface layer of the gas pill 15D, the gas generated by the gas pill 15D can be ejected from the gas ejecting holes 17D, so that the pressure intensity of the ejected gas is increased, and the operation of controllable gas ejecting direction is realized according to the setting size and the position of the gas ejecting holes 17D. And in the burning process of the gas pill 15D, the internal gas pressure is increased, so that the burning speed is higher, and the arc extinguishing reaction time is shorter.

As shown in fig. 7, the effect of the gas pellet is compared with that of the conventional gas generating device, a curve S1 is a graph showing the relationship between the time and the gas pressure of the arc extinguishing effect of the conventional gas generator, and a curve S2 is a graph showing the relationship between the time and the gas pressure of the arc extinguishing effect of the device of the present invention. By comparison, it can be seen that the reaction time required for the conventional gas generator to start extinguishing the arc is t2, whereas the reaction time required for the device of the present application is t1, and t2 is greater than t 1. Cause the contrast of this time difference to do, sleeve and spacing bucket that this application device set up, the base pressure of air shot and the increment pressure sum of sleeve are greater than the cracked critical pressure of air shot, the base pressure of air shot and the increment pressure sum of last framework and lower framework are greater than the cracked critical pressure of air shot simultaneously, make the air shot produce gas at the moment of being lighted and go up framework 2 and lower framework can not take place deformation, gas pressure rises rapidly, and certain deformation can take place for ordinary gas generator when producing gas, the volume increase, make the gas pressure rise not have the pressure height of the gas of this application. According to the relationship between the burning rate and the pressure: the higher the pressure is, the higher the burning speed is, so that the burning speed in the gas pill 4 of the device is higher than the burning speed of fuel in the common gas generator, and the gas spraying time of the device is faster than the gas spraying time block of the common gas generator and the arc extinguishing reaction time.

Meanwhile, comparing the arc extinguishing pressure and the arc extinguishing time, the maximum pressure at the detonation moment of the common gas generator in the curve S1 is P1, and the time period for reaching the pressure is very short, only the moment of detonation is enough, so that the arc extinguishing effect is poor. In the device, the time for reaching the pressure P1 during arc extinction is the time period t1-t3, and the time period t1-t3 is longer than the whole arc extinction time of the common gas generator, so that the arc extinction effect is very good, and the arc generated by a larger voltage transmission line can be extinguished. The reason is that the gas of the device can only be ejected from the gas ejecting holes, and the common gas generator directly explodes and ejects in multiple directions, so that the time for high-voltage arc extinguishing is very short. The time process that the high-pressure gas of the device needs to be sprayed out from the gas spraying holes is t1-t3, so that the gas pressure for arc extinction is high, the time for spraying the gas is long, the arc extinction effect is better, and the arc extinction can be carried out on special occasions and arcs with higher voltage levels.
