Anti-aging epoxy resin box-type transformer

Abstract

The invention provides an anti-aging epoxy resin box-type transformer. The transformer includes a box body and a transformer shell arranged in the box body; the box body and the transformer shell areboth made of a metal plate. An anti-aging coating layer, an electromagnetic shielding layer and a finish paint layer are sequentially arranged from inside to outside. The coating layer is prepared from 10-20 parts of butanol, 40-60 parts of zinc oxide-novolac epoxy resin, 20-30 parts of micro glass sheet, 20-30 parts of modified zinc oxide, 10-25 parts of polytetrafluoroethylene, 8-15 parts of polyurethane resin, 3-5 parts of polyvinyl acetate and 1-5 parts of other auxiliary agents. According to the invention, the anti-aging coating layer, the electromagnetic shielding layer and the finish paint layer are coated on the basis of the metal plate, three-layer protection is achieved, epoxy resin is modified to obtain zinc oxide-novolac epoxy resin, a micro glass sheet is introduced to preventrainwater, salt and the like from entering, modified zinc oxide and polytetrafluoroethylene are introduced to improve the corrosion resistance, coating degradation caused by ultraviolet rays can alsobe inhibited, and the aging resistance and corrosion resistance of the transformer are improved.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an anti-aging epoxy resin box-type transformer. Background technique [0002] Transformers are necessary electrical equipment in power transmission and distribution. In order to protect the transformer casing, paint is generally sprayed on the surface of the transformer box in the prior art to form a coating layer to prevent corrosion of the transformer box surface and at the same time Anti-insulation effect. Most of the electrical equipment is installed outdoors. Although the coating layer contains a large amount of organic matter, the coating layer will age under natural conditions, and the function of the coating layer will plummet, which will lead to the deterioration of the electrical equipment casing. Corrosion and aging will occur, and it will also make it difficult to guarantee the safety of electrical equipment. And when there are multiple electrical equipment in ...
