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.

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. Wherein the gas generated by the arc extinguishing unit directly influences the arc extinguishing effect.

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.

The limiting frame 12B, the sleeve 13B and the material binding layer are made of similar metal materials, and the thicknesses of the limiting frame 12B and the sleeve 13B are 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.

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.

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. 6, 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.
