Box structure of fully buried substation

Abstract

The invention discloses a box structure for a fully buried transformer substation, and the structure comprises a box body. A side wall of the box body comprises an internal housing, an external housing, and a hollow layer disposed between the internal housing and the external housing. The interior of the hollow layer is provided with a tap water pipe, and the hollow layer is fully provided with the tap water pipe in a wound manner. The upper part of the internal housing is provided with an internal circulating air incoming fan, and the internal circulating air incoming fan is communicated withan internal space between the hollow layer and the box body. The lower part, opposite to the internal circulating air incoming fan, of the internal housing is provided with an internal circulating air outgoing fan, and the internal circulating air outgoing fan is communicated with the internal space between the hollow layer and the box body. The box structure provides a relatively low temperaturespace for the transformer substation through the characteristics of continuous flowing and small temperature difference of tap water. The internal circulating air incoming fan and the internal circulating air outgoing fan exchange the air in the box body and the air in the hollow layer, thereby effectively solving a problem of heat dissipation of the fully buried transformer substation. The box structure has a complete heat dissipation function, and achieves the reasonable use of resources.

Description

technical field [0001] The invention relates to the technical field of substations, in particular to a box structure of a fully buried substation. Background technique [0002] The pre-installed substation is an indispensable and important part of the power system. It is sent to the load center by 10KV or 20KV medium voltage as the transmission and distribution voltage. After the pre-installed substation is transformed into 220 / 380 volts, the low-voltage voltage is sent to the user. The type can mainly ensure the stability of the user's voltage, reduce line loss, reduce voltage drop, and improve the quality of power supply. This type of substation device has brought many benefits to power supply and consumption, and is currently the best form of power distribution in the world. However, a large number of pre-installed substations, switch stations, and ring network cabinets have brought uncoordinated contradictions to the surrounding environment. There have been contradiction...
