Description

A grounding body exchange device for a low-voltage grounding wire

technical field

The utility model relates to a grounding body exchange device for electric grounding wires, in particular to a grounding wire grounding body exchange device suitable for low-voltage and 10KV distribution transformer maintenance operations, and belongs to the technical field of basic electrical components. the

Background technique

According to the requirements of relevant electric power construction codes, when overhauling low-voltage and 10kV distribution transformers, a set of low-voltage grounding wires should be hung on the low-voltage side of the distribution transformer to prevent sudden calls from causing harm to maintenance personnel. Since the low-voltage side outlets of some low-voltage and 10KV distribution transformers are insulated wires or cables, they do not have a suitable place to hang the ground wire. In addition, the currently used ground wires are generally hook-type, which is difficult to match with the outlet of the low-voltage distribution transformer. the

Utility model content
