Preferably, described high resiliency washer sets are made up of some spheric washers facing each other.
Preferably, the described sudden strain of a muscle face upper surface that connects is provided with the cylindricality slotted eye for rotating power-assisted.
A kind of wind power generation unit blade being provided with arrester, including blade, arrester and downlead, described downlead located at
In blade, described arrester is connected with downlead and is fixed on blade it is characterised in that described downlead includes main downlead
With auxiliary downlead, both pass through the first deconcentrator concatenation, wherein main downlead are also serially connected with some second electric wire connecting junctions, each the
Two electric wire connecting junctions are connected be made up of and line cable and metal tooth, and this metal tooth punctures and conducts auxiliary downlead；Described connect sudden strain of a muscle
Device is the arrester described in claim 1, and this arrester is installed on electric wire connecting junction by bolt.
Beneficial effects of the present invention:
1st, the present invention is conveniently replaceable using the fixing structure of arrester body and the combination of arrester parent；
2nd, the present invention is fixed by the way of arrester body and arrester parent grafting, rotation, and structure is simple, operation is fast
Prompt；
3rd, the present invention is using the high resiliency washer sets being socketed in connecting post, when arrester body and arrester parent grafting
Extruding high resiliency packing ring produces compressive deformation, and after arrester body ratates 90 degrees after fixing, the elasticity release of high resiliency packing ring will connect
Dodge device body to hold up, realize bottom connecting surfaces and the close physical connection of hollow cylinder top surface, realize electric current conduction；
4th, the present invention passes through to install main downlead and auxiliary downlead in blade interior, and it is double that initiative employing segmentation connects
Downlead designs, and ensures that each group of arrester on blade all conducts lightning current by two downleads, and in arrester
Puncture the deconcentrator connecting with employing of innovation in the connection of downlead, it is to avoid traditional blades downlead needs the broken string to pass through
Screw rod connects the redundancy backup keeping the technique of electrical continuity to realize blade lightning protection wire.
