Corrosion-resistant transformer for coastal areas

Abstract

The invention provides a corrosion-resistant transformer for coastal areas. The corrosion-resistant transformer includes a box body, wherein the transformer shell and the transformer main body are arranged in the transformer shell; the box body and the transformer shell are both made of metal plates; a saline-alkaline corrosion resistant coating layer, an anti-corrosion layer and a pigment layer are sequentially arranged on the metal plate from inside to outside; the coating layer is prepared from the following components in parts by weight: 10 to 20 parts of ethanol, 40 to 60 parts of modified epoxy resin, 15 to 25 parts of nano silicon carbide, 10 to 25 parts of polytetrafluoroethylene, 8 to 15 parts of polycarbonate, 3 to 5 parts of polyvinyl acetate, 3 to 5 parts of silica sol, 1 to 2parts of cerium nitrate, 1 to 2 parts of asbestos and 1 to 5 parts of other auxiliary agents. According to the invention, the saline-alkali corrosion resistant coating layer, the anticorrosive layer and the pigment layer are applied to the metal plate, wherein the saline-alkali corrosion resistant coating is prepared by modifying epoxy resin and introducing polycarbonate, nano silicon carbide, silica sol and polytetrafluoroethylene, and the weather resistance and saline-alkali corrosion resistance of the coating are improved.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a corrosion-resistant transformer used in coastal areas. Background technique [0002] Transformers are necessary electrical equipment in power transmission and distribution. The materials of transformers mainly include stainless steel, SMC, etc., and their corrosion resistance can meet the requirements of various harsh environments. However, at present most of the domestic transformers are made of galvanized steel plate, and its anti-corrosion performance is excellent in the inland environment dominated by weak acid corrosion, but in coastal areas or marine environments, due to seawater Alkaline, the anti-corrosion ability of the transformer in the saline-alkaline environment is not satisfactory. Therefore, it is of great significance to study a transformer used in coastal areas. Contents of the invention [0003] In order to overcome the problem of weak anti-corrosion ...
