Description

Technical Field

[0001] The utility model relates to the technical field of power distribution rooms, in particular to a power distribution room environment fire monitoring system. Background Art

[0002] The power distribution room, also known as the power distribution station, is an important facility used to distribute and control electric energy in the power system. The power distribution room is mainly responsible for converting the high-voltage electric energy transmitted from the power plant into low-voltage electric energy suitable for various types of electrical equipment, and supplying it to various power users. The power distribution room mainly includes high and low voltage distribution equipment, transformers, distribution cabinets, cables and other equipment.

[0003] The power distribution room is equipped with a fire protection system, which can extinguish the fire in time when a fire occurs, reduce the damage to equipment and property caused by the fire, and ensure personal safety. The type of fire extinguisher in the power distribution room is mainly selected based on the type of fire, the performance of the fire extinguisher and the characteristics of the power distribution room. Common types of fire extinguishers in power distribution rooms include dry powder fire extinguishers: dry powder fire extinguishers are suitable for extinguishing fires of electrical equipment, and have the advantages of fast fire extinguishing speed, wide fire extinguishing range, and not easy to reignite. However, dry powder fire extinguishers will produce a large amount of dust during the spraying process. These dusts will be suspended in the air and affect the air quality. In indoor environments, dust will be deposited on the surfaces of electrical equipment, furniture, etc., affecting the appearance and cleanliness, and the power distribution cabinet will produce harmful gases when burning. When the cables, plastic insulation layers or other organic materials in the power distribution cabinet burn, some toxic and harmful gases will be released. These harmful gases will pollute the air in the power distribution cabinet room and endanger the safety of workers in the power distribution room. In order to prevent dust from entering, the existing power distribution room mostly uses air conditioning for heat dissipation.
