An underground substation for power system

Abstract

The invention relates to a buried substation for an electric power system. The buried substation comprises a box body which is arranged under the ground. A protective cover plate is arranged above the box body. An intermediate interlayer is arranged in the wall of the box body. A semiconductor refrigeration chip is arranged in the intermediate interlayer which is filled with a cooling liquid. Heat dissipation pieces are arranged on the side wall of the box body. The inside heat dissipation pieces are communicated with the intermediate interlayer in the box wall. The semiconductor refrigeration chip is connected with a power supply through a first electromagnetic relay. A temperature sensor is arranged in the box body. A drainage fan is arranged in the box body. The air outlet of the drainage fan is connected with a dryer through a pipe. 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 connected with the power supply through a second electromagnetic relay. A humidity sensor is arranged in the box body.

Description

technical field [0001] The invention belongs to the technical field of power equipment, and in particular relates to an underground substation used in 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 th...
