Abstract

The invention discloses a buried integrated transformer device, which comprises a buried control room, an oil-immersed transformer accommodated in the buried control room, and a cooling fin installed on the side wall of the buried control room. In the technical solution of the present invention, by setting the heat sink embedded on the side wall, the heat energy in the oil tank is directly transferred to the side wall through the heat sink and diffused into the external soil. Compared with the prior art, the intermediate link of conducting heat through a medium with a low specific heat capacity, such as air, is omitted, thus greatly improving the heat dissipation efficiency. Not only that, the heat sink in the buried integrated transformer device of the present invention is separated from the oil tank, which greatly reduces the volume of the oil-immersed transformer and is more convenient for installation and maintenance.

Description

technical field [0001] The invention relates to the technical field of transformer devices, in particular to an underground integrated transformer device. Background technique [0002] Most of the traditional underground transformer installations install oil-immersed transformers directly in the control room, which has poor heat dissipation effect. In order to accelerate heat dissipation, it is necessary to increase the volume of the heat dissipation structure, thereby affecting the overall structure of the transformer and increasing the manufacturing cost. Not only that, the heat dissipation of the traditional buried oil-immersed transformer needs to dissipate the heat inside the oil tank to the air inside the control room through the corrugated sheets, and then transfer the heat to the shell of the control room through the air, and finally the heat from the shell Conducted to the external soil. Due to the low heat conduction efficiency of air, this heat dissipation metho...
