Description
Technical Field
The utility model relates to an electric power protection technical field especially relates to an accident oil bath of transformer substation.
Background
After a fire disaster occurs, the sprayed water drops are vaporized by heat to absorb a large amount of heat, so that the temperature of a combustion area and the surface of a main transformer is rapidly reduced, and when the surface of the main transformer is cooled to a certain temperature, combustible steam is not generated any more, and the combustion is stopped immediately. In addition, after the water spray is sprayed to the combustion area, the water spray is heated and quickly vaporized, and the water vapor covers around the transformer, so that the oxygen concentration in the combustion area is continuously reduced, the oxygen supply of a combustion object is cut off, and the combustion is restrained or interrupted. However, when the water spray is continuously sprayed to the surface of burning oil, the water spray is continuously stirred under the impact of the water spray, and part of the transformer oil is dissolved in the water body in an emulsified state, so that the content of the discharged oil exceeds the standard. Moreover, the amount of water sprayed at one time of water spray extinguishing is hundreds of, and the accident oil pool can not bear the oil-water mixture in such amount, so that effective oil-water separation is necessary.
The separation of oil water can only be realized to current accident oil bath, needs very big volume and settling time, but too big volume is unfavorable for the planning of transformer substation, and the sewage after the separation of accident oil bath directly discharges usually, causes water pollution easily, does not accord with emission standard.
