Does the distribution room need a gas fire extinguishing system? The stability and safety of the power distribution room is related to the electricity consumption of the entire building. Are there any relevant provisions in the fire protection code for the fire extinguishing design of the power distribution room, what kind of fire extinguisher or fire extinguishing system needs to be installed in the power distribution room, and is it necessary to install a gas fire extinguishing system? Nianhai Fire Fighting will explain it in detail for you.
The power distribution room is simply a room that distributes electrical energy. It mainly distributes electrical energy to users. It is equipped with switches, transformers, capacitors, and related protective measurement devices. Many buildings require separate power distribution rooms, such as large buildings such as residential quarters, hospitals, office buildings, and stations. Especially in summer, the power consumption increases sharply, the equipment cools down slowly, and the operation of the power supply system is particularly important. Among them, the safety of the power distribution room is even more important.
Electrical equipment such as power distribution cabinets, power distribution boxes, and incoming cabinets are stored in the power distribution room. Once a fire occurs, it will affect the operation of the entire power supply and distribution system, causing economic losses, and even serious life-threatening situations. The fire classification of the power distribution room can be found in the "Classification of Building Fire Extinguisher Configuration Design Code" GB50140, which belongs to the category E fire: fires of charged objects must be extinguished with fire extinguishers that can meet the requirements of electrical insulation performance.
According to the "Code for Design and Design of Building Fire Extinguishers" GB 50140-2005:
4.2 Type selection of fire extinguisher
4.2.1E fire place should choose ammonium phosphate dry powder fire extinguisher, sodium bicarbonate dry powder fire extinguisher, halo fire extinguisher or carbon dioxide fire extinguisher, but the carbon dioxide fire extinguisher equipped with metal horn spray can not be selected.
The residues of dry powder fire extinguishers have a certain fouling effect on electrical equipment, and halogenated fire extinguishers have been banned in China according to the Montreal Convention agreement. Therefore, the best choice for fire extinguishers in distribution rooms is portable carbon dioxide fire extinguishers, portable heptafluoropropane fire extinguishers and other clean gases Fire extinguishers are used as auxiliary fires. At the same time, the fire extinguisher in the power distribution room should be located in a location that is obvious and easy to access, and it must not affect safe evacuation.
The portable gas fire extinguisher in the power distribution room only serves as a supplementary function. In addition, the power distribution room needs to be equipped with an automatic fire extinguishing system. Obviously, the sprinkler fire extinguishing system is not suitable for the particularity of electrical equipment fires in power distribution rooms and power distribution rooms. Does the distribution room need a gas fire extinguishing system?
According to the GB50370 "Code for Design of Gas Fire Extinguishing Systems", typical application places or objects of gas fire extinguishing systems are as follows:
3.2.1 The gas fire extinguishing system is suitable for the following fires:
1 electrical fire;
2 solid surface fire;
3 liquid fire;
4 Gas fire that can cut off the gas source before extinguishing the fire.
"Fire Code for Architectural Design" GB50016 We know that power distribution rooms and power distribution rooms are special important equipment rooms. It is stipulated in the code that special important equipment rooms such as power distribution rooms should be equipped with automatic fire extinguishing systems, and gas fire extinguishing systems should be adopted.
It can be understood from the above that it is necessary to equip the distribution room with a gas fire extinguishing system, and it also meets the national fire protection regulations. As to which gas distribution system to choose, it needs to be considered from multiple levels.
