Specific embodiment

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.

Please refer to Fig. 2-5, a kind of Utilities Electric Co.'s special high-pressure electroscope, including telescopic rod I 1, telescopic rod II 2, telescopic rod III 3, detection module 4, metal probe 5 and hood guard ring 6, it is real that telescopic rod I 1, telescopic rod II 2 and telescopic rod III 3 distinguish pivot bush unit The end of existing Telescopic, telescopic rod III 3 is bonded extension bar for two by left and right, and the telescopic rod III 3 in left side is socketed on flexible In bar II 2, the telescopic rod III 3 on right side is fixedly connected on the end of detection module 4, sets at III 3 docking of telescopic rod of the left and right sides The cavity formed after thering is booster cavity 7, booster cavity 7 to be bonded by the docking of telescopic rod III 3 of the left and right sides, it is left in the inside of booster cavity 7 Right both ends are equipped with battery plate 8, and battery plate 8 is copper sheet, can be by the outer of the battery plate 8 on right side and detection module 4 to ensure security and stability Shell connection.

As a result, when operator occur fault such as adjustment distance of stretch out and draw back do not conform to mark, using specification and measured voltage grade not When closing mark etc., and electric discharge phenomena occur, high-voltage electricity can preferentially puncture 7 internal impedance of booster cavity, put so that generating between two battery plates 8 Electrical phenomena, so that gas ionization, electric discharge, fever in booster cavity 7, generate high pressure gas, instantaneously will test the related right side of module 4 Telescopic rod III 3 pops up, so that operator disconnects the contact with equipment under test at the first time, reaches the people of protection operator Body security purpose.

Wherein, telescopic rod II 2 is changed to be threadedly coupled with the pivot bush unit of telescopic rod I 1, specifically, in telescopic rod II 2 Outer end sets external screw thread 2a, and external screw thread 2a is connect with the inner thread of telescopic rod I 1, and protrudes into telescopic rod I 1 in telescopic rod II 2 End be equipped with limit plate 2b, the width of every section fillet of screw of external screw thread 2a is at least 5mm, and limit plate 2b is that adaptation is flexible just The inner wall of bar I 1 can uncap in the end of telescopic rod I 1, then will stretch to install telescopic rod II 2 and telescopic rod I 1 rationally The small head end of contracting bar II 2 is protruded into from the end of uncapping of telescopic rod I 1.Telescopic rod II 2 can be improved to telescopic rod I 1 in external screw thread 2a as a result, Hand grip portion creepage distance, because of field raining working or with when operation, the surface of telescopic rod is close to high-voltage electricity in dust environment When be also easy to produce voltage field uneven distribution and creepage phenomenon occur and causes shelf depreciation, such screw-type socket mode increase is climbed Away from can further ensure the safety of high-voltage electricity operation.

Wherein, it is additionally provided with fixed mechanism 9 in the outside of telescopic rod II 2, fixed mechanism 9 includes bolt 9a and fixed tension spring The both ends of 9b, fixed tension spring 9b are separately connected the outer wall of bolt 9a and telescopic rod II 2, and bolt 9a is inserted into the inside of telescopic rod II 2 And the inside pin joint with telescopic rod III 3, one end that bolt 9a is protruded into telescopic rod III 3 sets tapered ramp, and the tapered ramp is carried on the back To detection module 4, fixed mechanism 9 is the telescopic rod III 3 to fixed stretching, and when telescopic rod III 3 provides second protection, Gu The reaction force for determining mechanism 9 when can undertake the pop-up of detection module 4.

Wherein, it is additionally provided with reset tension spring 10 in the inside of telescopic rod II 2, reset tension spring 10 is stretched to telescopic rod III 3 When contracting bar II 2, pull-back forces are provided to telescopic rod III 3, in order to when packing up electroscope, as long as the bolt 9a of two sides is extracted Afterwards, under the pull-back forces effect of reset tension spring 10 telescopic rod III 3 is returned in telescopic rod II 2, it is easy to use.

Wherein, as shown in figure 5, being so that the docking of telescopic rod III 3 of two sides is secured, by the docking of the telescopic rod III 3 of two sides Mouth is set as side ring groove, a side ring flange collar, and the two is clamped just, adds viscose glue in outer ring gap.To may make The telescopic rod III 3 of two sides can have good anti-bending strength after docking, and use in order to stablize.

Wherein, the gas pressure intensity filled in booster cavity 7, can be depending on specifically used specification safety, for example, the electricity of 6kv Pressure uses specification, then the gas pressure intensity filled in booster cavity 7 is the electricity that can be carried between two battery plates 8 under the fixation cavity Lotus amount, corresponding 7 gas molecule of booster cavity is filling gas amount under the quantity of electric charge, then occur more than 6kv breakdown, ionization, Electric discharge phenomena, the pressure of generation are greater than the dynamics of viscose glue.
