Box-type transformer substation

Abstract

The invention discloses a box-type transformer substation, which comprises a box body consisting of a bottom plate, four side plates and a top plate, wherein a box door is arranged on the front side plate, shutter type ventilation openings are formed in the left side plate and the right side plate, the inside of the box body is separated into a high-voltage chamber, a low-voltage chamber and a transformer chamber through a separation plate, high-voltage switch equipment is arranged in the high-voltage chamber, low-voltage power distribution equipment is arranged in the low-voltage chamber, a transformer is arranged in the transformer chamber, a heat radiation and dehumidification device adopting the low-voltage power distribution equipment for realizing the power supply is also arranged inside the box body, and comprises a single chip microcomputer, a temperature and humidity sensor, an electric heater and a small-size fan, the single chip microcomputer is fixedly arranged on the inner side walls of the side plates, and the temperature and humidity sensor, the electric heater and the small-size fan are respectively connected with the single chip microcomputer. The box-type transformer substation has the advantages that the structure is simple, the design is reasonable, the use is convenient, the cost of the additionally arranged equipment is low, the overhaul and the maintenance are easy, and the heat radiation and dehumidification effects are good.

[0002] In the power system, box-type substations are widely used. Box-type substations are a kind of factory prefabricated indoor / outdoor compact power distribution equipment that integrates high-voltage switchgear, distribution transformers and low-voltage power distribution devices according to a certain wiring scheme. Realize functions such as high-voltage power receiving, transformer step-down, and low-voltage power distribution. The box-type substation includes a box body composed of a base, side walls, and a top cover. Room, transformer room and low-voltage room are respectively placed with high-voltage switchgear, distribution transformer and low-voltage power distribution device. The distribution transformer will generate a lot of heat when it is working, and if the heat is not dissipated in time, it will make the transformer The indoor temperature is too high, which will affect the normal operation of the transformer in severe cases

[0003] The current box-type transformer has ventilation holes on the side wall, but the heat dissipation effect is still not very good. The air in the box is not circulated, and a large amount of heat tends to gather in the upper part of the box and cannot be dissipated, which makes the temperature of the whole box continue to rise. High, adversely affect the internal equipment

In addition, in some time periods, such as the rainy weather in the south or the light rainy weather in winter, the humidity of the air is very high, and because the side plate of the box-type substation has ventilation holes, it is connected to the outside air. Therefore, The humidity inside the box will also be high, which will also seriously affect the normal operation of the transformer and the safe use of the transformer
