A switch cabinet with a voltage equalizing device

Abstract

The invention discloses a switch cabinet with a voltage equalizing device, including cabinet, the right side surface of the cabinet body is provided with a control switch group, the input terminal ofthe control switch group is electrically connected with the output terminal of the external power supply, a cabinet door is hinged at the open end of the front side of the cabinet body, A left side surface and a right side surface of that cabinet body are provided with ventilation grooves, a dust-proof net is arranged in the ventilation groove, a heating dehumidification device is arranged at theinner bottom end of the cabinet body, two symmetrically distributed insulating plates are vertically arranged inside the cabinet body, through holes are arranged on the side surfaces of the insulatingplates, and the side surfaces of the two insulating plates are fixed with bus bars by bolts and nuts. The switch cabinet with the voltage equalizing device has the advantages of safety in use, excellent performance, increased ventilation and heat dissipation capacity in the cabinet body, and timely heat dissipation, is capable of removing moisture in the cabinet body, avoiding damages of components in the cabinet body caused by humidity in rainy or cloudy days, avoiding bolt tip discharge in the overlap position of the bus bar in the cabinet body, optimizing electric field, and avoiding electric arc generation.

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to a switch cabinet with a pressure equalizing device. Background technique [0002] The switch cabinet is a kind of electrical equipment. The outside line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Such as instruments, automatic control, 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. load shedding. 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, disconnectors, load switches, operating mechanisms, tran...

AI Technical Summary

Problems solved by technology

During the use of the existing switchgear, the bolts at the lap joints of the busbars in the switchgear may easily cause metal tip discharge, and the ventilation and heat dissipation of the switchgear is poor, and the air humidity in rainy or cloudy days may easily cause damage to the electrical components in the switchgear. bring inconvenience
