An underground substation for power system

Abstract

The invention relates to a buried transformer substation for an electrical power system. The buried transformer substation comprises a box body arranged underground, wherein a protecting cover plate is arranged above the box body; an intermediate sandwich is arranged in the box wall of the box body; the intermediate sandwich is internally provided with a semiconductor refrigeration chip and is filled with refrigerant fluid; cooling fins are arranged on the side wall of the box body; the inner parts of the cooling fins are communicated with the intermediate sandwich in the box wall; the semiconductor refrigeration chip is connected to a power supply source through a first electromagnetic relay; a temperature sensor is also arranged in the box body; a drainage fan is also arranged in the box body; a dryer is connected to an air outlet of the drainage fan through a pipeline; a moisture absorbing layer and a heating layer are arranged in the dryer; the moisture absorbing layer is filled with calcium oxide powder; an electric heating wire is arranged in the heating layer; the drainage fan and the electric heating wire are both connected to the power supply source through a second electromagnetic relay; a humidity sensor is also arranged in the box body.

Description

technical field [0001] The invention belongs to the technical field of power system equipment, and in particular relates to an underground substation for a power system. Background technique [0002] With the continuous development of economic construction, more and more outdoor substations have emerged to provide material conditions for economic construction more conveniently. [0003] However, the construction of above-ground substations needs to occupy land area; therefore, buried substations have become an important aspect of outdoor substation construction; however, the buried substations in the prior art have the following technical problems: [0004] First: Due to the relatively tight seal of the buried substation, the heat emitted by the transformer and other power equipment inside cannot be discharged in time; Second: The buried substation is prone to damp, which affects the normal operation of the power equipment inside; Third: The buried substation is affected by...

AI Technical Summary

Problems solved by technology

[0004] First: Due to the relatively tight seal of the buried substation, the heat emitted by the transformer and other power equipment inside cannot be discharged in time; Second: The buried substation is prone to moisture, which affects the normal operation of the power equipment inside; Third: The buried substation is affected by the earthquake, causing damage to power equipment; fourth: it is easy to cause water accumulation; fifth: it cannot report to the remote control center in time
