Abstract

The invention discloses a safe explosion-proof power distribution cabinet, and relates to the technical field of electrical equipment. The safe explosion-proof power distribution cabinet comprises a cabinet body, the top of the cabinet body is movably connected with a sealing top plate, the top of the sealing top plate is fixedly provided with a waterproof shed, and the top of the waterproof shed is fixedly provided with a warning lamp. Through combination of a first electromagnetic valve, a nitrogen storage tank, a second electromagnetic valve and a smoke sensor, when a device in the cabinet body is on fire, the smoke sensor detects information of smoke emitted during fire, then the smoke sensor controls the first electromagnetic valve to be closed and controls the second electromagnetic valve to be opened, nitrogen in the nitrogen storage tank is released into the cabinet body, and oxygen in the cabinet body is discharged from a ventilation opening II, so that the oxygen content in the cabinet is not enough to support continuous combustion of the device, fire on the device is extinguished, an explosion-proof effect is achieved, the possibility that greater accidents possibly occur is avoided, and the safety of the explosion-proof power distribution cabinet is improved.

Description

technical field [0001] The invention relates to a safety distribution cabinet, relates to the technical field of electrical equipment, in particular to a safety explosion-proof distribution cabinet. Background technique [0002] Electrical equipment is a general term for generators, transformers, power lines, circuit breakers and other equipment in the power system. The important role played by electricity in our life and production cannot be ignored. It brings us great convenience and becomes our The production of important energy in life, the most critical factor in the power plant to allow the normal operation and transmission of electricity is electrical equipment. There are following problems at prior art: [0003] 1. The existing power distribution cabinets do not have explosion-proof functions. When a device in the cabinet fails and catches fire, the power supply can only be automatically cut off, and the open flame generated by the device cannot be extinguished in t...
