An underground substation with alarm function

Abstract

The invention relates to a buried transformer substation with an alarming function. The buried transformer substation comprises a box body arranged under the ground, wherein a protection cover plate is arranged above the box body; a middle interlayer is arranged in a box wall of the box body; a semiconductor refrigeration chip is arranged in the middle interlayer and the middle interlayer is filled with refrigeration liquid; a heat dissipation sheet is arranged on a side wall of the box body; the inner part of the heat dissipation sheet is communicated with the middle interlayer in the box wall; the semiconductor refrigeration chip is connected to a power supply through a first electromagnetic relay; the box body is internally further provided with a temperature sensor; the box body is internally further provided with a draught fan; an air outlet of the draught fan is connected with a dryer through a pipeline; the dryer is internally provided with a moisture absorption layer and a heating layer; the moisture absorption layer is internally filled with calcium oxide powder; the heating layer is internally provided with an electric heating wire; the draught fan and the electric heating wire are both connected to the power supply through a second electromagnetic relay; and the box body is internally further provided with a humidity sensor.

Description

Technical field [0001] The invention belongs to the technical field of power equipment, and specifically relates to an underground substation with an alarm function. Background technique [0002] With the continuous development of economic construction, more and more outdoor substations have emerged to provide more convenient material conditions for economic construction. [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, in the prior art, buried substations have the following technical problems: [0004] First: due to the relatively tight sealing of the underground substation, the heat emitted by the transformer and other power equipment inside it cannot be discharged in time; second: the underground substation is prone to moisture, which affects the normal operation of the power equipment inside; third: It is easy to cause accumulation o...

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 damp, which affects the normal operation of the power equipment inside; Third: It is easy to cause water accumulation; fourth: the transformer oil conservator in the buried substation explodes and the entire substation is paralyzed; fifth: the remote control center cannot be reported to the police in time
