Integration transformer substation for wind power generation

The invention provides a special integrated-type substation for wind power generation, comprising a semi-encapsulated impregnated insulated transformer unit, as well as a high voltage unit and a low voltage unit which are cast and sealed by epoxy resin. The transformer unit, the high voltage unit and the low voltage unit are fixed in a shell, showing a shape like a Chinese character 'pin'. The high voltage unit is connected to a high voltage end of the transformer unit through a touchable connecting cable, and the lower voltage end of the transformer unit is connected to an input end of the low voltage unit. The special integrated-type substation for wind power generation is arranged in a wind power generation host tower cylinder. The substation not only overcomes the disadvantage that the transformer unit, the high voltage unit and the low voltage unit in the prior substation for wind power generation are arranged independently and separately, but also completely gives play to the superiority of solid insulated electrical equipment, is long in life span and little in overload time, can automatically adopt speed limit measures or stop operating when a blower is overloaded, and can not be overloaded on the whole. The design that the substation is unattended reduces maintenance cost.
