Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage power transmission, in particular to a high-voltage power transmission and distribution lightning protection system. Background Art

[0002] High-voltage power transmission is a method of transmitting power by stepping up the voltage output by the generator through a transformer in a power plant. The reason for using this method of power transmission is that under the same transmission power, the higher the voltage, the smaller the current. In this way, high-voltage power transmission can reduce the current during transmission, thereby reducing the heat loss caused by the current and reducing the material cost of long-distance transmission. High-voltage transmission towers are used for high-voltage power transmission, but high-voltage transmission towers will be struck by lightning, so a high-voltage transmission and distribution lightning protection system is needed.

[0003] When operators perform lightning protection work on high-voltage power transmission and distribution, they often use the corresponding high-voltage power transmission and distribution lightning protection system. Although the existing system can achieve the purpose of lightning protection, in actual use, lightning rods or lightning arresters are mostly used for lightning protection. However, lightning arresters are mostly fixedly installed. When they fail, they need to be replaced as a whole, which reduces their practicality. In addition, the installation and fixing method of the lightning protection system is single, which may cause looseness during long-term use, affecting the normal lightning protection work.
