A self-controlled temperature type power transformation cabinet

Abstract

The invention brings forward a self-controlled temperature type power transformation cabinet. The internal portion of a main body is provided with a vertical division plate; the vertical division plate divides the main body into a first installation cavity and a second installation cavity; the vertical division plate is provided with a plurality of ventilation holes connecting the first installation cavity and the second installation cavity; a first cover plate and a second cover plate are matched with openings in the two ends of the main body to seal the main body; the first cover plate is provided with a first opening and a first air outlet; a first draught fan is arranged in the first opening; a second valve is arranged in the first air outlet; the second cover plate is provided with a second opening and a second air outlet; a second draught fan is arranged in the second opening; a third valve is arranged in the second air outlet; and a controller controls the first draught fan, the second draught fan, the first valve, the second valve and the third valve to work according to detection signals of a first temperature sensor, a second temperature sensor, a first humidity sensor and a second humidity sensor. The power transformation cabinet of the invention can realize automatic adjusting of the temperature and humidity inside the power transformation cabinet so as to facilitate stable, reliable and safe working of the power transformation cabinet.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a self-temperature-controlling type transformer cabinet. Background technique [0002] 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. In addition, 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 hazardous operations such as sh...

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.

In addition, 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 hazardous operations such as short circuits. hidden danger to personal safety
