Description

Technical field [0001] The invention belongs to the field of high-voltage power transmission lightning protection devices, and particularly relates to a high-voltage transmission line tower lightning protection device. Background technique [0002] High-voltage power transmission is a method in which the voltage output by the generator is boosted by a transformer in a power plant and transmitted. This transmission method is used because in the case of the same transmission power, the higher the voltage, the lower the current, so that high-voltage transmission can be Reduce the current during transmission, thereby reducing the heat loss caused by the current and reducing the material cost of long-distance transmission. However, due to the long transmission distance of high-voltage transmission lines and the intricate terrain passing by, it is prone to lightning strikes, which may cause the transmission lines to trip and power outages. Will burn the wire. Summary of the invention ...

AI Technical Summary

Problems solved by technology

[0002] High-voltage power transmission is a way to boost the output voltage of the generator through a transformer in a power plant and then transmit it. This method of power transmission is adopted because the higher the voltage is, the smaller the current is under the same power transmission power. In this way, high-voltage power transmission can Reduce the current during power transmission to reduce the heat loss caused by the current and reduce the material cost of long-distance power transmission. However, due to the long transmission distance of high-voltage transmission lines and the intricate terrain they pass through, they are prone to lightning strikes, which will cause the transmission line to trip and blackout. In severe cases will burn the wire
