Abstract

The invention provides filtering equipment for water in transformer oil and a use method thereof. The filtering equipment comprises an air compressor, a dryer and a triple filtering device, wherein connecting hoses are arranged among the air compressor, the dryer and the triple filtering device; the triple filtering device comprises a first filtering tank, a second filtering tank and a third filtering tank which are connected in sequence; each of the first filtering tank, the second filtering tank and the third filtering tank comprises an upper cover, a tank wall, a lower cover and super-hydrophobic filter cloth; the super-hydrophobic filter cloth is arranged above the lower cover, and the edge of the super-hydrophobic filter cloth is arranged between the tank wall and the lower cover; and a groove is formed in the middle of one side of the lower cover, an oil outlet hole is formed in the middle of the groove, and the oil outlet hole is provided with an oil outlet switch. The filtering equipment is used for removing trace moisture in the transformer oil without a large amount of energy consumption, and meanwhile, filtering precision can be improved; and moisture in insulating oil is finely filtered, so the operation safety and stability of oil filling equipment are improved.

Description

technical field [0001] The present application relates to the field of water-oil separation equipment, in particular to a moisture filtering equipment in transformer oil and a method for using it. Background technique [0002] Power grid construction has formed a number of large inter-provincial regional power grids. The operation mode of these regional power grids is long-distance, ultra-high voltage or even ultra-high voltage transmission. Due to long-distance power transmission, it is required to increase the transmission voltage to reduce power loss. [0003] The moisture in the transformer oil will reduce the breakdown voltage of the oil and reduce the life of the transformer. If the breakdown voltage drops to a certain level, it will directly cause the transformer to explode. Removing the moisture in the transformer oil is the focus of transformer maintenance. At present, the methods for removing moisture in transformer oil mainly include vacuum method, centrifugation ...
