Water-based fire extinguishing agent applicable to transformer oil fire

Abstract

The invention discloses a water-based fire extinguishing agent applicable to transformer oil fire and belongs to the field of transformer auxiliary materials. The water-basedfire extinguishing agent comprises 30-40 parts of kieselguhr, 8-13 parts of flame retardant, 5-10 parts of a lead salt stabilizer, 2-5 parts of a modifier, 5-20 parts of silicone oil, 1-5 parts of limestone powder, 7-9 parts of an adhesive, 35-40 parts of deionized water and 8-10 parts of sebacic acid. The water-based fire extinguishing agent which is disclosed by the invention and applicable to transformer oil fire is capable of extinguishing fire efficiently, effectively preventing self combustion of a transformer at a high temperature of oil fire, furthermore ensuring the use security of the transformer, and prolonging the service life of the transformer.

Description

technical field [0001] The invention belongs to the technical field of auxiliary materials for transformers, and in particular relates to a water-based fire extinguishing agent suitable for transformer oil fires. Background technique [0002] There is always the risk of fire in oil-immersed power transformers. The internal arc caused by overvoltage, short circuit, etc. makes the oil temperature exceed the ignition point, and decomposes a variety of combustible gases. Once the internal overpressure causes the oil tank to burst and rupture, resulting in oxygen Entering, encountering an open flame can cause a fire and cause great harm. At present, the transformer fire extinguishing system mainly includes oil discharge nitrogen injection fire extinguishing device, foam fire extinguishing device, water spray fire extinguishing device. However, the fire extinguishing efficiency of the oil discharge and nitrogen injection fire extinguishing device is low, the cost is high, and the...

AI Technical Summary

Problems solved by technology

However, the fire extinguishing efficiency of the oil discharge and nitrogen injection fire extinguishing device is low, the cost is high, and there are misoperations. Once the misoperation will cause serious damage to the main body of the transformer; the fire extinguishing efficiency of the foam fire extinguishing device is average, but the environmental pollution is serious; the fire extinguishing efficiency of the water spray fire extinguishing device Higher, but high water consumption, its fatal point is freezing below 0°C, it cannot be used in cold regions, which greatly limits its application range
