According to the thunder and lightning selection characteristic, promptly "point discharge" effect, the probability that the unit suffered the thunderbolt in this type of area is higher, consequently, the utility model provides a wind generating set's lightning arrester.

SUMMERY OF THE UTILITY MODEL

The above-mentioned is not enough among the prior art, the utility model provides a wind generating set's lightning arrester, its simple structure, convenient popularization.

A lightning arrester of a wind generating set comprises a wind driven generator main body and a lightning arrester, wherein the lightning arrester is fixedly installed at the top end of the wind driven generator main body, the wind driven generator main body is connected with the lightning arrester, the bottom of the lightning arrester is connected with a concrete foundation through a base, the concrete foundation is connected with a grounding grid of a pre-buried ground, and the lightning arrester is connected with the grounding grid through a grounding lead;

the lightning arrester comprises a triangular positioning rod, a base connected with the triangular positioning rod, a lightning rod arranged in the accommodating cavity, and three bases respectively arranged at the bottoms of the triangular positioning rod, wherein the base is provided with a through hole for installation on the wind driven generator main body.

Preferably, a limiting rod is further installed between the triangular positioning rod and the accommodating cavity.

Preferably, the base is a fixing flange, and fixing screw holes are formed in four corners of the fixing flange.

The utility model has the advantages that:

the utility model discloses wind generating set's lightning arrester adopts the lightning rod to trigger thunder device and comes to protect aerogenerator, and the ground net can be derived the electric current that the thunder and lightning produced fast, avoids suffering the thunder and lightning at thunderstorm weather generator and destroys, and the security is high.
