Automatic cooling, oxygen-inhibiting and fire-extinguishing system of low-voltage power distribution equipment

Abstract

The invention relates to an automatic cooling, oxygen-inhibiting and fire-extinguishing system of low-voltage power distribution equipment. The automatic cooling, oxygen-inhibiting and fire-extinguishing system comprises a fire detection module, a relay control module, a dry ice control module, a high-speed photographing module and a remote control module, after the fire detection module detects afire signal, the signal is transmitted to the relay control module, a relay coil is powered on, a normally open switch is closed, and a power supply is switched on for an electromagnetic valve of a double-layer heat preservation storage tank and a high-speed camera; after the electromagnetic valve is switched on, a bolt of the double-layer heat-preservation storage tank is pulled open, the double-layer heat-preservation storage tank is opened, dry ice is released, and fire extinguishing is implemented; meanwhile, after the high-speed camera is powered on, high-speed snapshot is conducted on afire point, snapshot pictures are uploaded to a server and stored in a database of the server, and reliable data are provided for post-disaster accident analysis; and a fire alarm unit of the serverimmediately sends a short message and a voice alarm signal to a mobile phone of operation and maintenance personnel when receiving the first snapshot picture.

Description

technical field [0001] The invention belongs to the technical field of fire-extinguishing and fire-fighting systems, and relates to a fire-extinguishing system, in particular to an automatic temperature-lowering and oxygen-suppressing fire-extinguishing system for low-voltage power distribution equipment. Background technique [0002] With the development of my country's modernization, people pay more and more attention to the prevention of fire. In recent years, the national fire protection law has promulgated and implemented relevant laws and regulations, and the prevention of fire in engineering construction has been raised to the height of law. [0003] At present, the protection of low-voltage power distribution room is mainly divided into two categories: electrical protection and fire protection. Electrical protection mainly isolates or removes the fault point from the circuit through relay protection. Protection is mainly to deal with the fire situation by fire extin...

Problems solved by technology

[0004] In the event of a fire, because the high-current equipment in the low-voltage power distribution room is prone to dangers such as breakdown and explosion, it is difficult for personnel to enter the power distribution room to extinguish the fire as soon as a fire occurs

Among the existing automatic fire extinguishing systems, according to the fire extinguishing materials, there are mainly automatic sprinkler systems, dry powder fire extinguishing systems, and foam fire extinguishing systems; because the power distribution rooms are all live equipment, it is not suitable to use sprinkler systems; dry powder The fire extinguishing system contains salts such as sodium chloride and phosphate, which are easy to cause corrosion to electrical equipment and are not easy to use; the foam fire extinguishing system contains a lot of water and is not suitable for electrical equipment fire extinguishing

[0005] After the accident, it is difficult to see the specific situation of the fire point in the fire investigation of power distribution equipment only by on-site video, which is not conducive to accident analysis
