Busbar connecting device for low voltage switchgear cabinet

Abstract

The present invention discloses a busbar connecting device for a low voltage switchgear cabinet. The busbar connecting device comprises a lower housing and an upper housing, the upper surface of the lower housing is provided with a threaded groove, the front end of the upper surface of the lower housing is provided with a wire outgoing hole, the upper portion of the wire outgoing hole is sleeved with a wire outgoing protection head, the upper housing is installed at the upper portion of the lower housing through set screw nuts, a wire incoming hole is arranged at the center of the top portionof the upper housing, and the upper portion of the wire incoming hole is sleeved with a wire incoming protection head. In the invention, the wire outgoing hole and the wire incoming hole are respectively sleeved with the wire outgoing protection head and the wire incoming protection head to effectively avoid damaging of a busbar and a sub-wire due to friction so as to better protect the busbar andwire incoming, the device is provided with a fastening piece in the wire incoming through hole to allow the fastening piece to clamp the busbar through fastening screws so as to ensure that the busbar is not in a loosening state, allow the device to better protect the busbar and make the device have better market prospects.

Description

technical field [0001] The invention relates to the technical field of low-voltage switchgear equipment, in particular to a bus connection device for low-voltage switchgear. Background technique [0002] The main function of the switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the switch cabinet are mainly composed of circuit breakers, isolating switches, load switches, operating mechanisms, transformers and various protection devices. The switch cabinet is a kind of electrical equipment. Sub-control switch, each branch is set according to its needs. Such as instruments, automatic controls, motor magnetic switches, various AC contactors, etc., some also have high-voltage room and low-voltage room switch cabinets, high-voltage busbars, such as power plants, etc. There are many ways to classify switchgear for load reduction. ...

AI Technical Summary

Problems solved by technology

[0003] The busbar connection device of the low-voltage switchgear is a device that connects the busbar into the low-voltage switchgear. However, most of the products on the market are simple in structure and have low protection measures for the busbar, which cannot meet people's needs.
