Moisture-proof drainage system for prefabricated substation and using method thereof

Abstract

The invention relates to the technical field of electric power facilities, and concretely relates to a moisture-proof drainage system for a prefabricated substation, and a using method thereof. The system comprises a foundation pit base, a cabinet body, a condensing device, a circulating device and a drainage device, and the upper end of the foundation pit base is fixedly connected with the cabinet body. The front end of the cabinet body is rotatably connected with a cabinet door. The upper end of the cabinet body is fixedly connected with a rainproof ceiling. The right end of the cabinet bodyis fixedly connected with a side mounting cylinder; and the lower end of the side mounting cylinder is fixedly connected with the foundation pit base. In the present invention, the condensing device,the circulating device and the drainage device are arranged, so automatic drainage of the transformer substation foundation pit can be achieved, moisture in the cabinet body is promoted to be condensed into water drops on the surface of the cooling pipe, accordingly, the moisture in the cabinet body can be removed, the interior of the cabinet body is kept dry, meanwhile, a radiator operates to suck in hot air in the cabinet body through the heat dissipation air pipe and then discharge the hot air, and heat dissipation of a cooling liquid and the cabinet body is facilitated.

Description

technical field [0001] The invention relates to the technical field of electric power facilities, in particular to a moisture-proof drainage system for a prefabricated substation and a usage method thereof. Background technique [0002] The prefabricated substation is designed by concentrating the traditional transformer in the box-type shell. The box-type transformer is a complete set of power distribution equipment. It is an organic combination of transformers, high-voltage voltage control equipment, and low-voltage voltage control equipment. Lightweight, low noise, low loss, high reliability, widely used in residential quarters, commercial centers, light stations, airports, factories, mines, enterprises, hospitals, schools and other places. [0003] At present, the prefabricated substations used in the market need to build a concrete foundation pit first, and then install the prefabricated substation on the top of the foundation pit.

AI Technical Summary

Problems solved by technology

[0003] At present, the prefabricated substations used in the market need to build a concrete foundation pit first, and then install the prefabricated substation on the top of the foundation pit. In rainy weather, the air is humid and there is a lot of rain, and rainwater is easy to accumulate in the foundation pit. Ordinary prefabricated substations mostly do not have a separate moisture-proof drainage system. After a sunny day, the evaporation of rainwater to form water vapor will easily lead to high humidity inside the box, and water droplets will easily adhere to electrical equipment, which may lead to safety accidents. Therefore, in view of the above problems, a prefabricated substation moisture-proof drainage system and its application method are proposed
