You can use IG5 41 or an aerosol for gas fire extinguishing. It is recommended that the specific design of gas fire extinguishing be carried out by a professional fire protection manufacturer. Fire extinguishing systems are divided into two categories. The first is that multiple fire extinguishers are interconnected via connectors to form an overall fire extinguishing system. Second, a single fire extinguishing device constitutes a fire extinguishing system in itself. 1. Multiple fire extinguishers are interconnected via connectors to form an integrated fire extinguisher. Refers to a group consisting of several fire extinguisher devices (devices), which are connected to each other via connectors according to predefined rules to form a whole. Depending on the set start mode (temperature detection, smoke detection, etc.), the system's extinguishers (devices) are started individuallyitself, several times or simultaneously to obtain a fire extinguishing system which cannot be completed by a single extinguisher (device) alone. 2. A single fire extinguishing device constitutes in itself a fire extinguishing system. The various components of the fire extinguishing system are assembled with each other, interconnected and limited to each other to form a relatively stable organization and structure, achieving fire extinguishing effects that the Ordinary fire extinguishers cannot get. Generally, this type of fire extinguishing system is large, has many components, contains a large quantity of extinguishers, has many powder outlets, and has diversified directions.
Why water can be used to extinguish a fire after a generator catches fire
Heptafluoropropane is a colorless, odorless, non-conductive gas with no posecondary llution. It is clean and low-polluting. toxic and has good electrical insulation. It has the characteristics of high fire extinguishing efficiency, no damage to the ozone layer, relatively short residual time in the atmosphere, and its environmental performance is obviously better than that of haloalkanes. to replace haloalkanes 1301 and 1211. When a fire occurs, heptafluoropropane equipment automatically ejects heptafluoropropane gas to extinguish the fire under anaerobic conditions.
Therefore, heptafluoropropane can be used to extinguish fires in generator rooms.
What should be used to extinguish fires in live electrical equipment, generators and motors?
Sand can be used, but if you use sand to extinguish fires you will be extinguished, but the sand cannot be cleaned and aDry powder fire extinguisher can also be used. However, foam extinguishers cannot be used because foam extinguishers conduct electricity.
Generators under 150 MW are usually cooled with hydrogen and. air-cooled and generators over 150 MW are water-cooled.
Water cooling is a separate circuit. It is not in direct contact with the winding or iron core. Instead, water circulates through the pipe and into the circuit. The winding or iron core is cooled externally. The sand is so fine that it would be very difficult to pour and clean. There is no guarantee that it can be completely eliminated. fire. If you want to use nitrogen for cooling, it is no different from air cooling, because the nitrogen in our air accounts for 78.12% of the total air and cannot achieve the effect of cooling. Use aliquid zote. The cost is too high. /p>
Carbon dioxide fire extinguishers should be used for energized electrical equipment and generator motors. Carbon dioxide fire extinguishers are suitable for extinguishing first fires involving flammable liquids and gases, and can also be used to extinguish fires involving electrical equipment. It is often used in laboratories, computer rooms, power transformation and distribution stations, as well as for the maintenance of precision electronic instruments, equipment or valuables. Looking for a higher place.
To extinguish electrical fires, use carbon dioxide, carbon tetrachloride, or dry powder extinguishers. You can also use sand, dry earth, etc. to put out fires. Remember not to use water to extinguish the infires, because water conducts electricity and can easily injure people by electric shock.
Detailed information:
When escaping a fire, do not blindly follow the flow. people and rush at each other. When evacuating, be careful and run to a bright spot or open space outside. After a fire, never take the elevator to escape. Use the fire escape and take the stairs to escape. When there are children or elderly people indoors, make a simple lifeline out of sheets, curtains, etc., and slowly lower it from the window sill to the floor or ground by underneath to help them escape as quickly as possible. After escaping from the fire scene, if your clothes are on fire, you should take them off as soon as possible. If you cannot remove them in time, vYou can roll over to put out the fire.
