A high temperature and corrosion resistant oil-immersed transformer

Abstract

The invention relates to a high-temperature-resistant corrosion-resistant oil-immersed transformer which is prepared by coating an anticorrosive paint on a transformer shell. The anticorrosive paint comprises the following components in parts by weight: 20-30 parts of 601 epoxy resin, 30-40 parts of red lead, 45-54 parts of talcum powder, 5-6 parts of diethylenetriamine, 7-9 parts of methylbenzene, 8-10 parts of ethyl acetate, 0.5-1 part of butanone, 1-3 parts of cyclohexanone, 5-9 parts of tert-butyl hydroperoxide and 25-35 parts of dibutyl phthalate. The oil-immersed transformer has the advantages of fewer raw materials, lower cost, simpler manufacturing technique and excellent corrosion resistance in high-temperature and high-corrosion environments.

Description

technical field [0001] The invention relates to a transformer, in particular to an oil-immersed transformer with anti-corrosion performance in a high-temperature and high-corrosion environment by coating anti-corrosion paint. Background technique [0002] In the production process of smelting and chemical industries, the emission of smoke and dust is relatively large, which has a serious corrosion effect on the metal shell of large transformers, especially the damage to the weak part of the transformer - the radiator. Corrosion has become a major hidden danger to the operation safety of large transformers, which affects the service life of transformers. It is economical and technically feasible to use paint protection for large transformers in operation. The operation is relatively simple and can be carried out by taking advantage of power failure opportunities. [0003] In the prior art, CN103509388 describes an epoxy resin transformer shell antirust paint, which consists ...
