Abstract

The invention discloses a temperature and humidity regulation and control system for a box-type transformer station. A side wall of a high-voltage chamber and a side wall of a low-voltage chamber are respectively provided with a heat-dissipation ventilation structure. The system comprises a temperature and humidity detection device, a controller, a cooling dehumidifying device, and a power module. Each heat-dissipation ventilation structure is provided with an air inflowing opening protection plate and an air flow outflowing top plate, wherein the air inflowing opening protection plates are rectangular structures which are disposed at the lower half parts of the side walls of the high-voltage chamber and the low-voltage chamber. The air flow outflowing top plates are rectangular structures which are disposed at the tops of the side walls of the high-voltage chamber and the low-voltage chamber, and are provided with two groups of rectangular ventilation units. The rectangular ventilation units respectively consist of a plurality of rectangular ventilation holes which are arranged to be parallel. The system can monitor the temperature and humidity of a transformer station, carries out the automatic regulation of the temperature and humidity, effectively achieves the ventilation and cooling of the transformer station, prevents the higher internal temperature of the high-voltage and low-voltage chambers of the transformer station from causing the aging of a line, and prolongs the service life of the transformer station.

Description

technical field [0001] The invention relates to a temperature and humidity control device, in particular to a temperature and humidity control system of a box-type substation, which belongs to the technical field of substation monitoring. Background technique [0002] The existing box-type substation includes a high-voltage room, a low-voltage room and a transformer room. In order to reduce costs, the entire box-type substation has a compact structure, but the heat dissipation and ventilation in the transformer room are not good. Especially in the hot summer, users consume a lot of electricity and the air temperature is high, and the heat dissipation of the box-type substation is even worse. Most of the existing box-type substations use natural heat dissipation. The heat dissipation of electrical components is mainly concentrated in the transformer room. Although heat sinks are installed on the transformer, the temperature in the transformer room is still high only through n...
