Moisture-proof semi-buried transformer substation and moisture-proof method thereof

Abstract

The invention discloses a moisture-proof semi-buried transformer substation and a moisture-proof method thereof. The transformer substation comprises a double-layer moisture-proof box body, a hollow box bottom and a moisture-proof box top. A moisture-proof system is arranged in the hollow box bottom. The moisture-proof system comprises an air storage convection area arranged on the upper layer ofthe hollow box bottom, and a heat collection moisture-proof area which is arranged on the lower layer of the hollow box bottom. The air storage convection area and the heat collection moisture-proof area are separated by an insulating isolation plate. A semiconductor refrigerator is mounted on the insulating isolation plate. Each side plate of the heat collection moisture-proof area is provided with a heat conduction network pipe fixedly arranged between interlayers of the double-layer moisture-proof box body. The side plate of the air storage convection area is provided with an air inlet driving mechanism. A plurality of layers of evenly-distributed breathable grids are arranged in the air storage convection area from top to bottom, and a dehumidification moisture-proof bag is laid on thesurface of each layer of breathable grids. According to the scheme, the moisture-proof function and the heat dissipation function are combined into an integrated moisture-proof mechanism; the interior and the exterior of the transformer substation box body can be effectively dried; and a damp passage of the transformer substation box body is blocked.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of substations, in particular to a moisture-proof semi-buried substation and a moisture-proof method thereof. Background technique [0002] A substation is a place in a power system that transforms voltage and current, receives electric energy and distributes electric energy. The substation in the power plant is a step-up substation, whose function is to boost the electric energy generated by the generator and feed it to the high-voltage grid. [0003] Traditional box-type substations, whose transformers and distribution cabinets are installed on the ground, occupy a large area, are extremely incompatible with the urban environment, and the noise will affect the lives of nearby residents. Therefore, many substations now choose to be buried. The buried substation is to completely bury the traditional box-type substation and semi-buried box-type substation under the ground, and the g...

Problems solved by technology

[0006] To this end, the embodiment of the present invention provides a moisture-proof semi-buried substation and a moisture-proof method thereof. A moisture-proof mechanism that combines the moisture-proof function and the heat dissipation function is used to effectively dry the inside and outside of the substation box. The substation box is exposed to damp passages, and the transformer components are cooled in a timely manner to solve the problems in the prior art that the moisture-proof method is poor, and the moisture-proof and heat-dissipating mechanism occupies a large space, and it is difficult to reasonably arrange it inside the substation box.
