A kind of cooling and dehumidification power cabinet based on semiconductor refrigeration sheet

Abstract

The present invention relates to a power cabinet, in particular to a cooling and dehumidification power cabinet based on a semiconductor refrigerating sheet, including a drying box, a semiconductor refrigerating sheet, an intake fan, a circulation pump, an air duct, a temperature and humidity sensor, a PLC controller, and a display , Exhaust fan, on the top of the power cabinet body, there are several series-connected semiconductor cooling chips, using the Peltier effect of semiconductor materials, cooling and dehumidifying the power cabinet at the cold and hot ends of the semiconductor cooling chips, temperature and humidity sensors, PLC controller , the monitor is used in combination, the temperature and humidity in the power cabinet can be seen intuitively from the monitor, and the PLC controller automatically controls the work of the semiconductor refrigeration chip, intake fan, circulation pump, and exhaust fan to realize intelligent cooling and dehumidification of the power cabinet, saving energy. Manpower, improve efficiency, high reliability, small footprint.

Description

technical field [0001] The invention relates to a power cabinet, in particular to a cooling and dehumidification power cabinet based on a semiconductor refrigeration sheet. Background technique [0002] As an important part of the power system, the power cabinet plays a very important role in the transmission process of the power grid. The normal operation of the electrical components in the power cabinet is an important guarantee for the normal transmission of the power grid. However, the electrical components inside the power cabinet are in A lot of heat will be generated when working for a long time, especially in summer, due to the small space inside the power cabinet, the heat inside the power cabinet is not easy to dissipate, and the electrical components inside the power cabinet will cause accidents due to aging or short circuit. , In the high temperature and rainy season, the air humidity is high, which will cause condensation inside the power cabinet.

[0002] As an important part of the power system, the power cabinet plays a very important role in the transmission process of the power grid. The normal operation of the electrical components in the power cabinet is an important guarantee for the normal transmission of the power grid. However, the electrical components inside the power cabinet are in A lot of heat will be generated when working for a long time, especially in summer, due to the small space inside the power cabinet, the heat inside the power cabinet is not easy to dissipate, and the electrical components inside the power cabinet will cause accidents due to aging or short circuit. , In the high temperature and rainy season, the air humidity is high, which will cause condensation inside the power cabinet. Condensation will cause corrosion of power equipment, short circuit and power outage accidents, causing great losses

[0003] When the power cabinet is in normal operation, it only needs a normal temperature, and it does not need to be too low. If the air conditioner is used to cool down, the air conditioner is large in size and takes up a lot of space, so it is very inconvenient to move
