What kind of gas fire extinguishing system can be selected in the power distribution room
Gas fire extinguishing agent is non-conductive and generally does not cause secondary pollution. It is a good fire extinguishing agent for fighting electronic equipment, precision equipment and valuable instruments. According to GB50016 of "Code for Fire Protection of Building Design", in important parts and places, the key equipment that will seriously affect production and life after a fire should use automatic gas fire extinguishing system, so the power distribution room should use gas fire extinguishing system.
From the perspective of safety and economy, what kind of gas fire extinguishing system can be selected in the power distribution room?
The high-pressure carbon dioxide gas fire extinguishing system has an instant cooling effect during fire extinguishing, and cannot protect high-precision electronic equipment; and because the high fire extinguishing concentration can produce instantaneous suffocation on people, it cannot be used to protect people's protection areas. In the power distribution room, there are not only generators and other equipment but also daily maintenance personnel, so high-pressure carbon dioxide equipment is not suitable for use in the power distribution room.
Heptafluoropropane fire-extinguishing system and IG541 fire-extinguishing system are fire-extinguishing systems that require high fire-extinguishing efficiency, protect large-volume protection areas, and ensure the safety of personnel evacuation. From the perspective of technology and economy, the cost of the heptafluoropropane project is relatively low, and the cost of later technology and equipment maintenance is also low. Therefore, the cabinet type heptafluoropropane is usually used in the smaller and more scattered protection areas, and the pipe network heptafluoropropane fire extinguishing system is used in the medium-scale power transformation and distribution room. However, it is an economical choice to install the IG541 gas fire extinguishing system when the protective place is large and the protective area is too large.
