Piercing clamps for ground potential live working of insulated conductors

Abstract

A puncture clamp for the ground potential live working of insulated wire line connection comprises an upper clamp unit and a lower clamp unit matching with the upper clamp unit. The positive surface of the upper clamp unit is provided with a main wire clamping groove with a downward opening, the main wire clamping groove is provided with upper puncture teeth inside, the lower clamp unit is provided with a guide wire limiting groove corresponding to the main wire clamping groove, and the guide wire limiting groove is provided with lower puncture teeth inside; a main wire is tightened through puncture of the upper clamp unit and lower clamp unit, and an auxiliary wire is tightened through a conventional press plate. The conduction is implemented and fine tightness property of insulted guide wire for insulation is guaranteed through puncture, safe and rapid ground potential live working for branch line connection is implemented, the problem of difficulty in insulated guide wire peeling is solved, the work intensity for operation is reduced, an outdated mode that peeling is necessary for operation for a long term is solved, the operating efficiency is improved by 50%, and the problems of water proofing and tightness caused by insulated guide wire peeling are solved.

Description

technical field [0001] The invention relates to a construction tool for electric power engineering, in particular to a puncture clamp for ground potential live work connected with insulated conductor lines. Background technique [0002] With the development of society, the network of distribution lines has proliferated, and the channel crisis has become the bottleneck of the development of the power grid. In order to solve the problem of line channels, the use of insulated wires effectively solves the problems of channel congestion and potential safety hazards. In the actual engineering construction process, the insulation layer of the wires needs to be stripped for crimping, jumper wires, and branch line connections. The thickness of the insulation layer of the 10kv insulated wire is about 4mm, and the thickness of the insulation layer of the 20kv insulated wire is about 6mm. Conventional stripping tools used in engineering construction include rotary type and conventional ...

AI Technical Summary

Problems solved by technology

Conventional stripping tools used in engineering construction include rotary type and conventional hand pliers type. The insulation layer is stripped during the operation, which is labor-intensive, labor-intensive and inefficient, and the accuracy is difficult to control. After the insulation layer is stripped, it is easy to Wire damage, especially when the insulation layer is stripped in cold winter, the hardness of the insulation layer increases and the stripping is more difficult

At present, all kinds of stripping devices have common problems such as high operating strength, low precision, and easy damage to the wires. The ground potential stripping is carried out to connect the branch lines with electricity, which directly causes the wires to not be well sealed, and rainwater immersion in the wires is not conducive. safe operation
