Cooling dehumidifying electrical cabinet based on semiconductor cooler

Abstract

The invention relates to an electrical cabinet, in particular to a cooling dehumidifying electrical cabinet based on a semiconductor cooler, comprising a drying box, a plurality of semiconductor coolers, an intake fan, a circulating pump, a gas guide pipe, a temperature-humidity sensor, a PLC (programable logic controller), a display, and an exhaust fan. The top of an electrical cabinet body is provided with the semiconductor coolers connected in series; Peltier effect of the semiconductor material helps cool and dehumidify the electrical cabinet at the cold and hot ends of the semiconductor coolers; the PLC automatically controls the semiconductor coolers, the exhaust fan, the circulating pump and the exhaust fan to operate, providing intelligent cooling and dehumidifying for the electrical cabinet; manpower is saved, efficiency is improved, reliability is high, and small space is used.

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. Condensation w...

[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
