Description

Technical Field

[0002] The distribution room refers to the place where electric energy is transmitted, distributed and converted in the power system. It is mainly responsible for converting the electric energy in the power grid into voltage levels suitable for the needs of different power-consuming equipment through transformers and other equipment, and safely and reliably transmitting it to various power consumption points. The distribution room plays a vital role in the power system and is a bridge connecting the power supply and power-consuming equipment. The electrical equipment in the distribution room needs to operate within a stable temperature range. High temperature may accelerate the aging of the internal components of the equipment, while low temperature may affect the startup and operation efficiency of the equipment. The equipment in the distribution room will generate a lot of heat during operation. If the ambient temperature is too high, it will affect the heat dissipation effect of the equipment, which may cause the equipment to overheat and be damaged. Therefore, in order to prevent equipment failure or performance degradation caused by excessively high or low temperatures, a temperature and humidity monitoring system is usually installed to monitor the indoor temperature and humidity in real time, and to promptly alarm when abnormalities occur.

[0003] In the related art, electrical equipment in the power distribution room, such as high-voltage switchgear and low-voltage switchgear, etc., mostly keep running when no fault occurs. They are used continuously for a long time. When the load of the line or equipment exceeds the rated value or exceeds the computing design capacity of the equipment, overheating is also likely to occur.

However, the cooling method in the prior art is slow and cannot quickly reduce the operating temperature of the overloaded equipment, and other equipment that is not overloaded is also easily affected by low temperature.
