Abstract
The invention discloses a corrosion-resistant protecting process of a waterproof, salt-spray-preventing and dustproof high-voltage power generator. The corrosion-resistant protecting process comprises a power generator component processing step, a standard member processing step, a stator integral processing steps and a rotor integral processing step. The power generator component processing step comprises protecting processing on components which are exposed from housing, namely an end cap, a fan seat, a wire outlet box, a net cover and an anti-drop cover, and protecting processing on an exciter stator and a permanent magnetic motor stator. A corona preventing low-resistance paint is sprayed in a winding slot of the stator core. VPI vacuum paint dipping is performed on a main stator by means of epoxy anhydride dipping resin. An epoxy insulating pain is sprayed on the end of the main stator winding and the surface of the stator core. Shot blasting phosphatization corrosion-resisting processing is performed on the housing. After epoxy priming paint is sprayed on the integral outer surface of a rotating shaft, black epoxy protective painting is sprayed. The corrosion-resistant protecting process provided by the invention settles a problem that a high-voltage power generator cannot perform long-term stable operation in adverse environments such as airborne dust, high humidity and high salt spray.
Description
technical field [0001] The invention relates to a corrosion-resistant protection process for a generator, in particular to a corrosion-resistant protection process for a waterproof, salt-fog, and dust-proof high-voltage generator. Background technique [0002] With the development of modern technology, the demand for electricity in all walks of life is increasing, and the market demand for high-voltage generators is on the rise. High-voltage generators are more and more used in data centers, industrial and mining, post and telecommunications, ships, docks and other fields. . In many fields, harsh environments such as dust, high humidity, and high salt spray require generators to have high-performance protection and corrosion resistance. At present, the high-voltage three-phase AC generators manufactured at home and abroad adopt conventional protection, that is, the stator winding adopts the insulation system of polymica and epoxy resin; the rotor winding is coated with epox...
