Technical Field

The invention belongs to the technical field of transformer auxiliary materials, and particularly relates to a water-based fire extinguishing agent suitable for transformer oil fire.

Background

The oil-immersed power transformer always has the danger of fire hazard, the oil temperature exceeds the ignition point due to internal electric arcs caused by overvoltage, short circuit and the like, various combustible gases are decomposed, once the internal overpressure causes the oil tank to explode and break, oxygen enters, and the fire hazard can be caused when the oil tank meets open fire, so that great harm is caused. At present, a transformer fire extinguishing system mainly comprises an oil discharge and nitrogen injection fire extinguishing device, a foam fire extinguishing device and a water spray fire extinguishing device. However, the oil-discharging nitrogen-injecting fire extinguishing device has low fire extinguishing efficiency and high cost, has a malfunction condition, and can cause serious damage to the transformer main body once the malfunction occurs; the foam fire extinguishing device has general fire extinguishing efficiency, but serious environmental pollution; the water spray fire extinguishing device has high fire extinguishing efficiency, but high water consumption, and the fatal point is that the water spray fire extinguishing device is frozen below 0 ℃, so the water spray fire extinguishing device cannot be used in cold regions, and the application range of the water spray fire extinguishing device is greatly limited.

At present, related researches on transformer oil fire extinguishing agents at home and abroad are few, and Chinese patent CN1188678A discloses a water-based extinguishing agent, the main components of which are phosphoric acid and salts thereof, boric acid and salts thereof, carbonate and silicate, and mainly aim at wood fire and gasoline fire; chinese patent CN101366999A describes a water-based fire extinguishing agent, which comprises fluorine-containing surfactant, fatty alcohol, fire retardant, etc., and is mainly used for extinguishing gasoline fire and industrial ethanol fire.
