Problems solved by technology

[0002] A large number of aluminum parallel-groove clamps are used for the connection of strain-resistant drain wires of 35-110kV high-voltage transmission lines. These aluminum parallel-groove clamps are exposed to the wild environment for a long time, and aging, brittle cracks, heating and melting often occur. For live replacement, due to the small distance b

Example Embodiment

[0037] Example 1

[0038] A live-replacement JB type parallel groove clamp tool includes an insulating operating rod, a parallel groove clamp body disassembly device 1, a parallel groove clamp pressure plate disassembly device, and a bolt disassembly device.

[0039] The disassembling and assembling device 1 of the parallel groove clamp body is as figure 1 , 2 As shown, it includes a trough-shaped body whose size is consistent with the body of the parallel grooved wire clip. A set screw 11 is provided on one side of the trough-shaped body. The head of the set screw on the side of the trough-shaped body is provided with an insulating operating rod. The connecting device 111 matched with the connecting device of the trough-shaped body is provided with an elastic compression piece 12 at the screw-in end of the set screw on the side of the trough-shaped body, and one or more set screws 13 are distributed on the bottom surface of the trough-shaped body. The position of the set screw on ...

Abstract

The invention discloses a tool for replacing a JB type parallel groove clamp on a live line, which comprises an insulating operating rod, a parallel groove clamp body dismounting device, a parallel groove clamp press plate dismounting device and a bolt dismounting device. The live replacement of the parallel groove clamp is realized through the arrangement of a unique structure. The tool can greatly reduce the investment of manpower, and also greatly improve the work efficiency and the operation safety, and has high economic benefit.

Description

technical field [0001] The invention relates to a tool for live working, in particular to a tool for live replacement of JB-type parallel groove line clamps. Background technique [0002] A large number of aluminum parallel-groove clamps are used for the connection of strain-resistant drain wires of 35-110kV high-voltage transmission lines. These aluminum parallel-groove clamps are exposed to the wild environment for a long time, and aging, brittle cracks, heating and melting often occur. For live replacement, due to the small distance between the ground clearance of the tension pole and tower drain line of the 35-110kV voltage level line, the use of the equipotential operation method for live replacement and ditch wire clip operation has a high safety risk, requires complicated and tedious preparations, and is inefficient , and some even failed to complete due to insufficient safety distance. Contents of the invention [0003] The purpose of the present invention is to o...
