Description

Telescopic wiring rod for high voltage diagnostic test

technical field

The utility model relates to a connecting rod used for a test of a high-voltage transformer, in particular to a connecting rod used in a high-voltage diagnostic test of a transformer.

Background technique

High voltage diagnostic tests are playing an increasingly important role in the safe operation of power grids. The traditional high-voltage test method requires the use of insulated bucket trucks or aerial work pliers to perform high-altitude disconnection, wiring and replacement of wires in the air, and use insulating tape to pull and fix the high-voltage leads. This method has the problems of time-consuming, laborious and high-risk operations.

Contents of the invention

The utility model provides a telescopic wiring rod for high-voltage diagnostic tests, which solves the problem of time-consuming, time-consuming, and high-altitude work clamps that need to use insulated bucket arm trucks or high-altitude operation pliers to perform high-altitude disconnection, wiring and wire replacement in the existing high-voltage test methods. The problem of laborious and high-risk climbing operations.
