Background technology
Wind-driven generator current transformer（Or frequency converter）At work, energy loss fever phenomenon can be produced.Current transformer master
Circuit devcie, such as IGBT, reactor, transformer etc., produce substantial amounts of heat.Generally, using back to back circuit topologies,
IGBT is as switching device, and the loss of IGBT, which can account for, flows through the 3% of converter system energy, and the reactor loss of rectification side accounts for
3%.Thus, there is amount of heat to need to exchange in external environment condition in time inside current transformer.

Tentaculum）, reduce system reliability.In addition, simple air-cooled or water cooling, when variation of ambient temperature scope is larger, effect is bad, than
Such as 45 DEG C of environment temperature superelevation, current transformer interior environment temperature can be more than 45 DEG C.Temperature is to electronic component, electric component longevity
Life image is larger.Such as electrolytic capacitor, near general 25 DEG C, device lifetime is most long, and as temperature raises, device lifetime is reduced,
When temperature is to 45 DEG C, the service life is reduced at double.For another example, in the service life of Switching Power Supply, raised with temperature, life and reliability all subtracts
It is small.
Another scheme is water cooling, and water cooling is used for the cooling of IGBT constant power modules, is filled inside current transformer by heat exchange
Put, carry out water-wind-heat and exchange.This scheme can realize that current transformer inner air and outer air completely cuts off, and strengthen environmental suitability.But same wind
Cold the same, when environment temperature is higher, current transformer internal temperature can be some higher.The equally reliability to converter system and longevity
Life has a great influence.
