Description

Technical Field

[0001] This utility model relates to the field of ring network box technology, specifically an insulated wrench for plug-in ring network boxes. Background Technology

[0002] A ring main unit is an electrical device consisting of a set of power transmission and distribution equipment (high-voltage switchgear) housed in a metal or non-metal insulated cabinet or assembled into a modular ring network power supply unit. Its core components are load switches and fuses. It has advantages such as simple structure, small size, low price, improved power supply parameters and performance, and enhanced power supply safety. It is widely used in substations and prefabricated substations in load centers such as urban residential areas, high-rise buildings, large public buildings, and factories. The cable plugs inside the ring main unit usually require an insulated wrench for connection to prevent accidental electric shock.

[0003] A plug-in head for a ring main unit is disclosed in Chinese Utility Model Patent Application Publication CN216354912U. Although the plug-in head of this ring main unit has the advantages of simple structure and easy assembly, it has the disadvantages of making it inconvenient to clamp the cable plug of the ring main unit, reducing the convenience of connecting the cable plug of the ring main unit, and the actual operation of the device is not flexible enough and the connection operation of the cable plug of the ring main unit is inefficient.
