Preassembling-type transformer station

The invention relates to a preassembling-type transformer station. The preassembling-type transformer station comprises a main transformer, a high voltage side switch device connected to the high voltage side of the main transformer and a low voltage side switch device connected to the low voltage side of the main transformer. The preassembling-type transformer station also comprises an SVG device connected with the low voltage side switch device. The high voltage side switch is a GIS module, the low voltage side switch device is a switch cabinet and the SVG device is an SVD cabinet. A primary part of the main transformer is connected with the high voltage side switch device and the switch cabinet through a sleeve or an insertion cable. According to the invention, the low side switch device is of a switch cabinet structure and the SVG device is of an SVG cabinet structure, which can be prefabricated in a factory and directly installed after being transformed to the place, so a transformer station house buildi
