Rapid cooling and dehumidifying substation cabinet

Abstract

The invention provides a rapid cooling and dehumidifying substation cabinet. A first cooling cavity is formed in a first side wall of a cabinet body; a second cooling cavity is formed in a second side wall; a third cooling cavity communicated with the first cooling cavity and the second cooling cavity is formed in a bottom plate of the cabinet body; the first cooling cavity, the second cooling cavity and the third cooling cavity are filled with a cooling liquid; a cover plate is matched with an opening of the cabinet body to seal the cabinet body; and a first baffle plate and a second baffle plate sequentially partition the inside of the cabinet body into a first chamber, a second chamber and a third chamber. The cabinet body is cooled through the cooling liquid, the cooling liquid is timely refrigerated and cooled through a circulating pump and a refrigerating device, and cold and heat exchange of the cooling liquid and the cabinet body is kept in balance, so that the cooling target in the cabinet body is achieved, waste of cold is avoided, the humidity balance in the cabinet body is maintained in ventilation and air exchange manners, the humidity in the cabinet body is controlled within a safety range in real time, the damp-proof effect is good, and meanwhile, one part of heat in the cabinet body can be taken away through introducing air.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a rapid heat dissipation and moisture removal transformer cabinet. Background technique [0002] Because of its low cost and convenient maintenance, the box-type substation has gradually attracted people's attention, and its application range has become wider and wider. It has gradually replaced substations in various urban and rural areas. Due to the concentrated distribution of multiple devices in the cabinet type substation, the space is small and the heat dissipation is difficult. The substation will release a lot of heat during the working process, which will cause the temperature to rise and affect the reliability of the internal equipment. When the substation works at high temperature for a long time, it may even cause a fire hazard. When the temperature difference between the inside and outside of the cabinet-type substation is too large, it is easy to accum...

AI Technical Summary

Problems solved by technology

The substation will release a large amount of heat during the working process, which will cause the temperature to rise and affect the reliability of the internal equipment. When the substation works at high temperature for a long time, it may even cause a fire hazard.

When the temperature difference between the inside and outside of the cabinet-type substation is too large, it is easy to accumulate moisture, which increases the humidity inside the substation, and the equipment in the cabinet-type substation is eroded by moisture, which affects the working stability and service life, and may even cause short circuits and other hazards to the operator. safety hazard
