Description
Technical field
The utility model relates to a kind of offshore wind farm and uses dry-type transformer, belongs to offshore wind farm transformer technology field.
Background technology
At present, wind-powered electricity generation is as a kind of regenerative resource of cleaning, and development is swift and violent in the world.Offshore wind farm because its aboundresources, wind speed are stable, less and allow the unit manufacturing more to maximize to the negative effect of environment, can large-scale development etc. advantage, receive wind-powered electricity generation developer's concern always.Because the special running environment (high humility, high salt density) of offshore wind generating group; The power transformer that is incorporated into the power networks that is used to boost can not adopt oil-immersed type transformer to be installed in the unit outside as land unit again; And adopt dry-type transformer to be installed in the cabin usually; So both solved the floor space problem of whole unit, and also avoided step-up power transformers is installed in the problems such as protection difficulty that lower position brings simultaneously.Harsh weather and environmental condition when adapting in the cabin operation, dry-type transformer should have the strong characteristics of resistance to corrosion.Dry-type transformer is installed in the offshore wind turbine cabin, safeguards and the maintenance cost height that dry-type transformer should have higher reliability.Simultaneously, because the restriction of the size in cabin own, the volume and weight of dry-type transformer also has strict requirement.And general transformer; The type of cooling adopts self cooling or air-cooled, the circulation of air in transformer case inner air and the cabin, and the air of the high moist high salt fog in the cabin gets into transformer case; Cause transformer device structure spare by heavy corrosion, transformer insulated level reduces greatly.Simultaneously, general transformer coil adopts copper coil usually, and Heavy Weight is difficult to satisfy the restriction of cabin load to transformer weight.
The utility model content
The purpose of the utility model provides a kind of offshore wind farm and uses dry-type transformer, and volume is little in light weight, and is anticorrosive, and reliability is high, solves the problems referred to above that background technology exists.
The technical scheme of the utility model is: offshore wind farm is used dry-type transformer; Comprise setting in the enclosure high-tension coil, main empty path, low-voltage coil, baffler, core lamination and be arranged on cooling fan, air channel, the heat-exchange device on the shell; High-tension coil and low-voltage coil ecto-entad are arranged on the core lamination, between high-tension coil and the low-voltage coil main empty path are set, and top is provided with baffler; Cooling fan connects shell and heat-exchange device through the air channel.
Also be provided with outside water pump, external heat switch, be connected into loop structure with heat-exchange device.
Said high-tension coil is a subsection cylindrical formula structure, and low-voltage coil is that paper tinsel is around structure; High-tension coil and low-voltage coil adopt aluminium matter conductor material to process the top mounting guiding board; The shell protection grade is provided with cooling fan, air channel and heat-exchange device greater than IP44 on the shell.In the transformer running; Cooling fan sucks the air channel to hot-air in the shell, carries out exchange heat at the heat-exchange device place, and outside water pump and external heat switch are taken away heat through boiler water circulation; The air of cooling gets into outer casing underpart; Under the baffler guiding,, transformer coil is cooled off through transformer main empty path and the inner air flue of low-voltage coil.
The good effect of the utility model: the dry-type transformer winding adopts aluminium matter, and the type of cooling adopts air portion's circulation in the enclosure, and not only volume is little in light weight, and anticorrosive, reliability is high, adapts to the harsh environment for use of offshore wind farm.
