Description

Technical Field

[0001] The utility model relates to the technical field of hydropower stations, in particular to a lightning protection device for a hydropower station. Background Art

[0002] A hydropower station is a place where water energy is converted into electrical energy. It uses the potential energy of water to generate electricity. Its working principle is to use the difference in water level (potential energy) to flow under the action of gravity (kinetic energy). By diverting water from high-level water sources such as rivers or reservoirs to a lower level, the water flow drives the turbine to rotate, driving the generator to generate electricity. To protect hydropower stations from the effects of lightning, corresponding lightning protection devices are generally installed in hydropower stations.

[0003] Existing lightning protection devices are often installed on high-voltage lines, but it is difficult to stabilize the position of the lightning protection device through a single high-voltage line, which leads to certain limitations when installing the lightning protection device.
