Anticorrosive and insulating power equipment and manufacturing method thereof

Abstract

The invention discloses anticorrosive and insulating power equipment and a manufacturing method thereof. A composite layer comprising an unsaturated polyimide solvent-free impregnating resin layer and a fluorinated silicone rubber layer is coated on the surface of a power equipment body, thus the anticorrosive and insulating power equipment has not only higher insulativity but also better anti-corrosion properties. Taking a stator of a generator for example, the anticorrosive and insulating stator of the generator coated with the composite layer has six-phase cold insulation resistance to the ground of 1,500 megohms and good properties of ultraviolet ray resistance, ozone resistance, oil prevention, chemical agent resistance, salt spray resistance, temperature fluctuation resistance and mildew resistance, and water absorption rate of 0.16 percent, can resist environmental attack, and has no scaling and no crazing. The composite layer of the anticorrosive and insulating power equipment has first level adhesive attraction, more than 20-year service life and low cost, and the composite layer of the anticorrosive and insulating power equipment and the power equipment body have better compatibility and breakdown voltage conservation rate of over 81.5 percent.

Description

technical field [0001] The invention relates to an insulating anticorrosion power equipment and a manufacturing method thereof. Background technique [0002] Generators operate on land and will be eroded by rainwater and wind and sand. Once the insulation of the generator is eroded by rainwater, the insulation resistance will soon drop to a very low level, or even zero in severe cases. If wind and sand intrude into the generator, dust may adhere to the end of the coil, making the creepage distance insufficient and causing corona. Generators run on the seaside and at sea, and they will be eroded and damaged by rainwater, salt spray, and mold, which will cause the stator core of the generator to rust. The above situations will affect the normal operation of the generator, so the generator must be treated with anticorrosion. [0003] At present, the commonly used anticorrosion treatment for generators is to apply alkyd resin on the surface of the generator stator, but the alk...

Problems solved by technology

[0003] At present, the commonly used anti-corrosion treatment of generators is to apply alkyd resin on the surface of the generator stator, but the water resistance and salt spray resistance of alkyd resin are poor, and the anti-corrosion effect is not good.
