Self-triggering fireproof switch cabinet

Abstract

The invention belongs to the technical field of switch cabinets, particularly relates to a self-triggering fireproof switch cabinet, and aims to solve the problems that due to the fact that an existing switch cabinet is poor in fireproof performance and does not have an automatic fire extinguishing function, the safety of a low-voltage switch cabinet is poor. The switch cabinet comprises a switchcabinet body and a carbon dioxide storage tank; a mounting hole is formed in one side of the top of the switch cabinet body, a heated cylinder is fixedly mounted in the mounting hole, a box body is fixedly mounted at the top of the heated cylinder, the carbon dioxide storage tank is fixedly mounted at the top of the switch cabinet body, and a gas outlet of the carbon dioxide storage tank communicates with one end of a gas outlet pipe. The carbon dioxide gas is guided into the switch cabinet through the self-triggering device when the switch cabinet works abnormally, generates heat and needs afire disaster, the fire disaster is prevented, the fan blades are driven to rotate through flowing of the gas so as to accelerate distribution of the carbon dioxide gas and dissipate heat of the switch cabinet, and the using effect of the switch cabinet is improved.

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to a self-triggering fireproof switch cabinet. Background technique [0002] Each branch of the switchgear is set according to its needs, such as instrumentation, automatic control, motor magnetic switch, various AC contactors, etc. Some also have high-voltage room and low-voltage room switchgear, with high-voltage busbars, such as power plants, etc. Some There is also a low-cycle load shedding to ensure the main equipment. The low-voltage switchgear is suitable for power plants, petroleum, chemical industry, metallurgy, textiles, high-rise buildings and other industries, as power transmission, power distribution and power conversion. [0003] The existing closed cabinets have poor fire protection performance and do not have the function of self-extinguishing fire, which leads to poor safety of low-voltage switch cabinets. In addition, when a fire occurs in a low-voltage swi...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing closed cabinets have poor fireproof performance and do not have the function of self-extinguishing fire, resulting in poor safety of the low-voltage switchgear. In addition, when a fire occurs in the low-voltage switchgear, the fire is very easy to spread to other The low-voltage switchgear has the disadvantage of causing greater economic losses, and a self-triggering fire-resistant switchgear is proposed
