Therefore, how to solve the problems of water resistance, salt fog resistance, damp and hot resistance, mould resistance and reliable positioning of the transformer body in ship operation becomes the central problems of transformer design and manufacture. In order to meet the requirements of salt mist resistance, damp-heat resistance and mould resistance, the outgoing copper bars and the conducting rods are subjected to silver plating treatment. All the parts are required to have the characteristics of water resistance, salt mist resistance, damp and hot resistance and mould resistance, and all the transformer external sealing gaskets are made of high-quality corrosion-resistant nitrile rubber. The outer surfaces of the transformer steel plates are all subjected to shot blasting treatment, and the surface paint of the steel plates is special primer for marine ships, so that salt mist, damp and hot resistance and mould resistance of the whole transformer shell are guaranteed. However, at present, a device for preprocessing the transformer oil tank is not provided, and when shot blasting is performed on gaps between radiating pipes on the surface of the transformer oil tank by traditional manual work, the problem of low efficiency exists, and the problem of uneven shot blasting also exists due to the influence of experience of operators, so how to design a steel plate preprocessing device for the whole transformer shell to realize preprocessing of the transformer oil tank is very important for improving the production quality and the production efficiency of transformer manufacturing. In view of this, we propose a steel plate pretreatment apparatus for manufacturing a marine transformer.
