The down conductor that one section of cable is constituted, arrester is connect with down conductor, after arrester is connected to lightning current, passes through grounding lead
It is offline to be transmitted to the earth by wheel hub, cabin, pylon.But blade arrester arranges that limited amount, especially 2010 are year pervious
Unit, at most setting two, quantity is obviously insufficient, greatly reduces thunder and lightning and connects sudden strain of a muscle efficiency, fan blade can not be effectively prevent to meet with
By lightning strike accident.But it since fan blade installs arrester additional, needs to remove in blade, transformation difficulty is larger, and the modification scheme is not
It is feasible.Therefore, it is imperative to find a kind of Lightning Transformation scheme of feasible fan blade.
Invention content
For the above situation, to overcome the defect of the prior art, the purpose of the utility model to be just to provide a kind of wind-force hair
Electric turbines vane Lightning Transformation device can effectively solve the take place frequently wind generator set blade Lightning Transformation in area of thunderstorm and ask
Topic.
The technical solution that the utility model solves is a kind of wind generator set blade Lightning Transformation device, including blade
Ontology is provided at least one arrester, the lower end of arrester and the down conductor phase positioned at blade body in blade body
Even, the lower end of down conductor is connected after stretching out blade body with the earth, is covered on blade body surface and is led with arrester
The connected aluminium row in electric part, aluminium row be longitudinal aluminium isostere by arrange along blade body length direction and be distributed on longitudinal aluminium row
The conductive integral structure that body and perpendicular connected lateral aluminium isostere are constituted.
At least 1 tip segment for being located at blade body of the arrester.
The total length of the longitudinal direction aluminium isostere is more than the 1/5 of blade body total length.
The aluminium row is adhesively fixed on the surface of blade body by double faced adhesive tape.
The end of the transverse direction aluminium isostere is equipped with the rivet for further fixing aluminium row, after rivet passes through lateral aluminium isostere
It is fixedly connected with fixed aluminium row.
The utility model structure novel is unique, and advantages of simple is easy to produce, easy to operate, at low cost, can effectively solve wind-force hair
The problem of electric turbines vane lightning stroke, fixes lightning protection aluminium row in blade surface, increases blade thunder and lightning and connect sudden strain of a muscle area, improve thunder and lightning and connect sudden strain of a muscle
Rate is reequiped on existing blade, easy to use without re-working blade, is easy to be transformed, and is wind-force hair securely and reliably
Innovation on motor group Lightning Transformation device.

Fig. 2 is the vertical view of the utility model.
Fig. 3 is the enlarged partial sectional view of the utility model aluminium row.
Specific implementation mode
Specific embodiment of the present utility model is described in further detail below in conjunction with attached drawing.
It being provided by Fig. 1-3, the utility model includes blade body 1, and at least one arrester 5 is provided in blade body 1,
The lower end of arrester 5 is connected with the down conductor 6 positioned at blade body 1, after the lower end stretching blade body of down conductor 6
It is connected with the earth, the aluminium row 2 being connected with 5 current-carrying part of arrester is covered on 1 surface of blade body, aluminium row 2 is by along leaf
1 length direction of piece ontology arrangement longitudinal aluminium isostere 21 and be distributed on longitudinal aluminium isostere 21 and the perpendicular lateral aluminium being connected
The conductive integral structure that isostere 22 is constituted.
To ensure using effect, at least 1 tip segment for being located at blade body 1 of the arrester 5；
The total length of the longitudinal direction aluminium isostere 21 is more than the 1/5 of 1 total length of blade body.
The arrester 5 has 2, one of them is located at the tip segment of blade body 1, another is located at blade body 1
Middle part.
The aluminium row 2 is adhesively fixed on the surface of blade body 1, the end of the transverse direction aluminium isostere 22 by double faced adhesive tape 4
Equipped with the rivet 3 for further fixing aluminium row, rivet 3 is fixedly connected after passing through lateral aluminium isostere 22 with fixed aluminium row 2, two-sided
Glue 4 can be used the hydrophobic double faced adhesive tape of high intensity, and longitudinal aluminium row is directly adhesively fixed on blade body surface by when transformation, is glued
It connects after fixing, is further fixed by rivet.
