AI Technical Summary

Technical Problem

The prior art is difficult to effectively solve the problem of abnormal heating of outdoor equipment cable clamps without power outage, resulting in shortening of equipment life and frequent grid failures, and manual climbing and processing are complex, time-consuming, high risks and high costs.

Method used

An equipotential wire clamp is designed, including a hooking bracket and a wire clamp unit. The insulated rod of the hooking bracket lifts the wire clamp unit, so that the high-voltage joint extends between the moving contact fingers, and relying on the frictional resistance between the moving contact fingers and the high-voltage joints, the upper support shaft and the lower support shaft are removed, thereby realizing clamping and diversion of the wire clamp unit, reducing the current flowing through the high-voltage joint, and solving the heating problem.

Benefits of technology

It realizes the rapid and effective solution to the abnormal heating problem of outdoor equipment cable clamps without power outage, extend the equipment life, reduce the risk of power grid failure, and reduce the complexity and cost of manual processing.

Abstract

An equipotential wire clamp and method for eliminating abnormal heating of outdoor equipment wire clamps relates to the technical field of power maintenance, and solves the problem of emergency shutdown caused by abnormal heating of outdoor equipment wire clamps and abnormal heating of equipment wire clamps in substations in a non-stop manner to meet the power supply reliability requirements. It includes a hanging bracket and a wire clamp unit, the lower part of the hanging bracket is fixed with an insulating rod, and the upper part of the hanging bracket has an upper hanging hole and a lower hanging hole arranged up and down; the wire clamp unit includes an upper support member and a lower support member arranged up and down and hingedly connected, one end of the upper support member and one end of the lower support member both have a spring seat, a spring is provided between the two spring seats, and the other end of the upper support member and the other end of the lower support member both have a moving contact finger. The present invention solves the heating problem of the high-voltage connector by clamping and shunting the high-voltage connector to reduce the current flowing through the high-voltage connector.
