Problems solved by technology

[0002] In order to control the temperature and humidity in the electrical room and prevent condensation in the high-voltage electrical cabinet, air conditioners are currently used, and some also use dehumidifiers at the same time. However, after long-term use, it is found that this does not prevent condensation, because the air conditioner only controls the electrical room. temperature and humidity, but can not control the temperature of the cable trench
If the air conditioner is used excessively, it will cause cold surfaces on the surface of electrical equipment and cause condensation
The principle of using a dehumidifier is to reduce the indoor moisture content and control the moisture content in the air to prevent condensation, but it also cannot solve the temperature and humidity of the cable trench. The cold and humid air in the cable trench follows the air in the cabinet. The thermal expansion and contraction are sucked into the sealing gap of the incoming and outgoing cables and accumulated in the cabinet. When the temperature difference between the room temperature and the inner and outer surfaces of the high-voltage equipment reaches the dew point, condensation will inevitably occur
Especially in the state of low temperature and high humidity in the cable trench, it will directly affect the internal temperature and humidity of the high-voltage electrical cabinet. Condensation on the surface and outside of the cabinet

Abstract

The invention relates to a temperature control and condensation prevention system for a high-voltage electrical cabinet, in particular to a temperature control, humidity control and condensation prevention technology for the high-voltage electrical cabinet in a high-voltage electrical room provided with an air conditioner. The electrical room is provided with a cable duct and comprises an air ductfor connecting the electrical room and the cable duct, wherein a fan for supplying air to the cable duct and a heating device for heating the air supplied by the fan are arranged in the air duct; andthe fan and the heating device are controlled by an intelligent control system, and the intelligent control system is connected with a temperature and humidity sensor. According to the temperature control and condensation prevention system for the high-voltage electrical cabinet, on the basis that a cooling function of the air conditioner is reserved, moisture in the cable duct is removed by supplying the air into the cable duct, the moisture in the duct is prevented from entering the high-voltage electrical cabinet through a gap between an inlet cable plugging opening and an outlet cable plugging opening, and meanwhile the purpose of temperature and humidity balance of the cable duct and the electrical room is achieved.
