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 damp, which affects the normal operation of the power equipment inside; Third: The buried substation is affected by the earthquake, causing damage to the power equipment; fourth: it is easy to cause water accumulation; fifth: the explosion of the transformer oil pillow in the buried substation causes the entire substation to be paralyzed

Abstract
The invention relates to an underground transformer substation for an outdoor power supply system. The underground transformer substation comprises a box which is arranged underground, wherein a protecting cover plate is arranged above the box. The underground transformer substation is characterized in that a middle interlayer is arranged in a box wall of the box; a semiconductor refrigeration chip is arranged in the middle interlayer, and a refrigerant fluid is filled in the middle interlayer; a radiating fin is arranged on a side wall of the box; the interior of the radiating fin is communicated with the middle interlayer in the box wall; the semiconductor refrigeration chip is connected with a power supply through a first electromagnetic relay; and a temperature sensor is arranged in the box.
Description
technical field [0001] The invention belongs to the technical field of power equipment, and in particular relates to an underground substation used in an outdoor power supply 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 i...
