Technical field
The present invention relates to wind-driven generator, be specially a kind of 1.5 MW offshore type air-air cooling double-fed asynchronous wind-driven generators.
Background technology
According to statistics, about 1,000,000,000 kw of the wind energy content that China can develop at present, wherein, about 2.53 hundred million kw of land wind energy content, but about 7.5 hundred million kw of the wind energy content of sea development and utilization.Along with the fast development of China's wind power technology, land wind energy resources can not be satisfied the demand, and the exploitation of coastal waters and offshore wind generating group is the development trend of China's wind generating technology.
Coastal waters, the world and offshore wind farm technology have entered the commercial development stage; China also is in the starting stage at present; the existing absolutely empty cooling double-fed asynchronous wind generator of 1.5 megawatts is Lu Yongxing, can not satisfy the anti-salt fog of coastal waters or marine unit, anti-damp and hot, mould proof special running environment requirement.Offshore type wind-force electrical machinery running environment is defined as according to ISO 9223: open not closed environment (T3), moderate SO2 pollutes (P2) and high salt fog (S3) coastal region.Ambient temperature :-40 ℃～+ 50 ℃.Humidity: 10～88%.If use under this paralic environment, each parts of wind-driven generator will be because of humidity and the salt mist environment that is in the coastal waters, and occur mouldy, get rusty and adhere to a large amount of solid salt particles, thereby have influence on the operate as normal of wind-driven generator.
Summary of the invention
The present invention provides a kind of 1.5 MW offshore type air-air cooling double-fed asynchronous wind-driven generators in order to solve the problem that existing wind-driven generator is not suitable for off-shore operation, easily gets rusty.
The present invention is concrete to adopt following technical scheme to realize:
1.5 MW offshore type air-air cooling double-fed asynchronous wind-driven generator, comprise support, stator, rotor, end cap, the brush holder-slip ring system that contains the slip ring chamber, stator terminal box, rotor junction box and the hollow cooler that is fixed in the generator top, stator and rotor cores, the moistureproof ageing-resistant silicon fluoride paint layer of rotor winding surface anticorrosion with painting; Support, end cap, slip ring chamber, stator terminal box and each component surface of rotor junction box welding back of being made with cut deal carry out Shot Blasting, the anti-salt fog skin of paint of spraying; Dust-removing box, each parts of cover plate welding back of being made with thin plate carry out zinc-plated processing (promptly covering zinc coat), the anti-salt fog skin of paint of spraying; With non-mating surface hacking, the salt fog skin of paint is prevented in spraying after seal ring, the balancing frame assembling; Electric connected component busbar, line nose with copper or copper alloy material adopt electrotinning to handle (promptly covering tin coating); Securing member zinc chrome coating is handled (promptly covering zinc-plated chromium layer).Outsourcing pieces such as hollow cooler, slip ring-brush holder system, self-acting lubricator, encoder are selected anti-salt fog type for use.
Compared with prior art; provided by the invention 1.5 MW offshore type air-air cooling double-fed asynchronous wind-driven generators have anti-salt fog, anti-damp and hot, mould proof special-effect; can be in paralic environment the stable operation that lean on of safety, can satisfy wind-driven generator in the coastal waters or the condition of marine operate as normal.
