Wind energy is a renewable and clean energy source, and wind power generation is the power resource with the most large-scale development conditions today. In order to obtain more wind energy, the single-unit capacity of wind power generators spd which is pv surge protective device is constantly increasing with the height of the hub and the diameter of the impeller. , the risk of lightning strikes is also increasing.

As towering and protruding objects on the ground, wind turbines are exposed to long-term exposure and are mostly located in wilderness areas, so they are very vulnerable to lightning strikes. The transmission device, power generation equipment and control system cause severe accidents that cause the unit to stop operating, thereby causing greater economic losses. The special surge protector for wind power system adopts excellent non-linear overvoltage protection components. Under normal circumstances, the surge protector is in a high-impedance state and the leakage current is extremely low, so that the system can supply power normally.

When a surge overvoltage occurs in the power system, the surge protector will be turned on immediately in nanoseconds, limiting the overvoltage amplitude within the safe working range of the equipment, and releasing the surge energy into the ground. Subsequently, the surge protector quickly changes to a high-resistance state, so as not to affect the normal power supply of the wind power system.
