Problems solved by technology

The components in the switchgear are mainly composed of circuit breakers, isolating switches, load switches, operating mechanisms, transformers and various protective devices. Once a fire breaks out when the current switchgear is in use, it will be given to the interior when the fire is extinguished after the staff finds it out. Instruments, automatic control, motor magnetic switches, etc. are damaged. In order to reduce losses, a switch cabinet with automatic fire extinguishing function is urgently needed

Abstract

The invention belongs to the technical field of switch cabinets, in particular to a switch cabinet with an automatic fire extinguishing function. In view of the fact that the existing switch cabinet has no automatic fire extinguishing function, the following scheme is put forward: the switch cabinet with the automatic fire extinguishing function comprises a cabinet body; a fire extinguisher is installed on the outer wall of the top of the cabinet body; the output end of the fire extinguisher is provided with an air outlet pipe; the inner wall of the air outlet pipe is provided with a solenoidvalve; an air injection pipe is mounted on the outer wall of the bottom part of the air outlet pipe; air nozzles equidistantly distributed are arranged on the outer wall of the bottom part of the airinjection pipe; a smoke sensor is mounted on the outer wall of one side of the top of the cabinet body; and a processor is mounted at the inner wall of the other side of the top of the cabinet body. Through arranging an alarm, the fire extinguisher, the smoke sensor, the air injection pipe, the air nozzles and the solenoid valve, when the inner part of the cabinet body is on fire and smoke is generated, the smoke sensor receives the signal and transmits the signal to the processor, a fire extinguishing material in the fire extinguisher is sprayed through the air nozzles below the air injectionpipe, and the fire on electrical appliances inside the cabinet body is extinguished.

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to a switch cabinet with an automatic fire extinguishing function. 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. [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 are mainly composed of circuit breakers, isolating switches, load switches, oper...
