Description

A high-voltage line anti-rain backflow device

technical field

The invention relates to the technical field of power grid equipment, in particular to a high-voltage line rainwater backflow prevention device.

Background technique

The high-voltage line needs to be hung on the tower pole with an insulator. Although the insulator is made into an umbrella sheet and has a lip tape to prevent rain, the insulating ability is also reduced in cloudy and rainy days, and the leakage current will increase relatively. In cloudy and rainy days, the air becomes humid, the dielectric constant between lines and lines and between lines and ground changes, the distributed capacitance of the conductor increases, the loss angle of the distributed capacitance also increases, and the active loss and reactive power loss of the leakage current increase. When it rains, raindrops will fall on the wires, and they will drip after a period of time. Due to the high voltage of the high-voltage circuit, the raindrops will be filled with some electric charges, and the leakage current will also increase. The air is easier to ionize on cloudy and rainy days, and the noise generated by high-voltage ionization is silent. Discharge and sound discharge will also increase a lot. In addition, for high-voltage power transmission, the impact of DC power transmission is slightly less than that of AC power transmission in cloudy and rainy days.

Therefore, a high-voltage line anti-rainwater backflow device is proposed. The upper computer control device opens the baffle in rainy days to prevent the insulator from being damp and leaking electricity, causing the risk of electric leakage.
