Problems solved by technology

[0002] The high-voltage capacitors and high-voltage reactors in the high-voltage reactive power compensation device are sensitive to temperature, and have certain requirements on the external environment temperature during use; when the capacitor is working normally, the surrounding rated ambient temperature is generally -20 ° C ~ 40 ° C; The temperature of the internal medium should be lower than 65°C; if the temperature is too high, the service life of the high-voltage capacitor will be shortened. The high-voltage capacitor breaks down and explodes, causing a bigger accident
The reactor in the high-voltage reactive power compensation device, according to its working principle of electromagnetism, will generate a large amount of heat during work, which will further increase the internal temperature of the high-voltage reactive power compensation device, resulting in a greater existence of the high-voltage reactive power compensation device. security risks
[0003] At present, the placement of capacitors and reactors in high-voltage reactive power compensation devices is relatively random. Many capacitors and reactors in high-voltage reactive power compensation cabinets are placed close to each other. In this way, the heat generated by the reactors is easy to affect the capacitors, which seriously affects the service life of the capacitors. The reactor will also be aging due to long-term high temperature; and the heat dissipation efficiency of the existing high-voltage reactive power compensation cabinet is low, and the dust-proof performance is lost due to the setting of the heat dissipation system, and the existence of dust has no effect on the high voltage. The power compensation device will cause adverse effects, causing a vicious circle and seriously reducing the service life of the equipment
