Problems solved by technology

[0003] 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 switchgear mainly include circuit breakers, isolating switches, load switches, The high and low voltage switchgear is a kind of switchgear. The existing high and low voltage switchgear can be used indoors or outdoors. When in use, it is easy to be corroded, or it is not resistant to high temperature when the temperature is high, which shortens the service life of the switchgear

Abstract

The invention discloses a high-temperature-resistant low-voltage switchgear cabinet. The switchgear cabinet comprises a cabinet body and a cabinet door installed on the cabinet body, the cabinet body is externally coated with a layer of a high-temperature-resistant coating through spraying, and the high-temperature-resistant coating comprises the following compositions: organosilicon-modified epoxy resin, a silicate filler, a levelling agent, a silane coupling agent, a dispersant, diantimony trioxide, an adhesion promoter and composite rare earth. The switchgear cabinet is simple in structure and convenient to use, and possesses good high-temperature resistance.

Description

technical field [0001] The invention relates to a switch cabinet, in particular to a low-voltage switch cabinet with high temperature resistance. 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 switchgear, high-voltage busbars, such as power plants, etc., and some also have low-cycle load shedding to ensure the main equipment. [0003] 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 switchgear mainly include circuit breakers, isolating switches,...
