AI Technical Summary

Technical Problem

Traditional busbar sockets cannot adapt to the new State Grid standard for normal pressure switchgear, resulting in inconvenient installation and the inability to implement an upper isolation and lower grounding design.

Method used

Design a busbar socket with an insulator and center conductor structure, including a plug port and a "7"-shaped crank arm. The plug and longitudinal handle are staggered to ensure creepage distance and shorten size. It is fixedly connected with an L-shaped plate to achieve convenient and safe installation.

Benefits of technology

Under the new standard for atmospheric pressure switchgear, the installation of busbar sockets is convenient and safe, and the design of upper isolation and lower grounding is supported, meeting the requirements of the State Grid standard.

Abstract

The utility model relates to a bus socket and a normal pressure switch cabinet, an isolation switch device in a cabinet body is arranged above a vacuum switch unit, the bus socket comprises an insulator and a central conductor, the insulator is provided with a plugging port and a second end portion, the central conductor comprises a plugging conductive rod correspondingly arranged in the plugging port, and the second end portion is provided with a second end portion. The plug-in conducting rod is connected with an electric connecting piece, the electric connecting piece is provided with an electric connecting portion corresponding to the second end portion, the insulator comprises a plug-in seat portion with a plug-in port formed in one end, a 7-shaped connecting lever is integrally formed on one transverse side of the plug-in seat portion and comprises a lateral protruding portion protruding on the transverse side wall of the plug-in seat portion, and the plug-in seat portion is provided with a plug-in port formed in the other end of the plug-in seat portion. The end part of the longitudinal handle part forms a second end part, the longitudinal handle part extends along the direction opposite to the direction of the plugging port, the second end part on the longitudinal handle part is longer than the end part of the plugging seat part, and the longitudinal handle part of the bus socket extends to an electric connection end at the top of the disconnecting switch device and is electrically connected with the electric connection end. The bus socket is reasonable in structural design and convenient to install and use.
