Description
Technical field
The utility model provides a kind of refrigeration-type transformer case, belongs to electrical equipment technical field.
Background technology
Transformer case plays the effect that protection transformer safety is run, and avoids foreign matter to enter in transformer and causes security incident, can available protecting personal safety, and plays certain electromagnetic shielding action.In addition, can amount of heat be produced because transformer is in operation, cause transformer temperature to raise, and temperature directly determines the useful life of transformer, for the transformer of A class F insulation, along with the increase of temperature, ageing of insulation will be accelerated, and transformer working life will reduce.In order to ensure that transformer is safe and reliable to operation, extending the useful life of transformer, guaranteeing that the temperature of transformer is very important in normal range (NR); Although current used transformer is provided with fin on its housing, but in summer of sweltering heat, and when transformer load is overweight, fin does not often have good thermolysis, therefore the temperature of transformer can be caused to exceed normal range (NR), thus reduce the useful life of transformer, or even cause the generation of accident.
