Beneficial effect of the present invention: lightning conductor is embedded in the web and one-body molded with web, improved the Security of blade lightning protection system greatly, thoroughly eliminate the many hidden danger because causing separating between lightning conductor and the web bringing to blade, reduced the blade production time simultaneously.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technological scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is preparation process FB(flow block) of the present invention.
Embodiment
Further describe the present invention below in conjunction with specific embodiment and accompanying drawing.
A kind of pre-buried technology of wind electricity blade lightning conductor as shown in Figure 1, its process using mode pre-buried and that one is solidified is embedded in lightning conductor on the web, and concrete steps are as follows,
1), laying lightning conductor and web molding vacuum material near a coxostermum of blade arrester, and reserves conductor length at the lightning conductor two ends, reserve in the position that lightning conductor connects the blade arrester wiring metal piece is installed;
2), the lightning conductor on web lays glass cloth, and is and lightning conductor is sealed at both ends;
3), adopt the priming by vacuum method with lightning conductor and web one-step solidification moulding.
This technology is to carry out lightning conductor to lay after existing production technology is carried out web shop layer, and the laying of web molding vacuum material, is existing process engineering for web shop layer and web molding vacuum material, does not repeat them here.For the laying of lightning conductor, it should be noted that 1, conductor length need be reserved in the lightning conductor two ends, and 2, installation wiring metal piece is reserved in the position that connects the blade arrester at lightning conductor, and 3, before perfusion, need lightning conductor is sealed at both ends.
Installation steps for described wiring metal piece comprise,
1.1), the position that connects the blade arrester at described lightning conductor removes the copper cable that is exposed with the protective layer of lightning conductor, and at described web the metal copper billet is installed;
1.2), adopt increasing pad and the bolt of A4 shape that aforementioned exposed copper cable is pressed on the metal copper billet, and laying the foam angle of wedge carries out transition all around at the metal copper billet;
1.3), lay to cover copper billet, and lay two-layer glass cloth covering copper billet and the foam angle of wedge.
Here, selected metal copper billet is the copper billet of one 80mm * 60mm * 10mm; And the protective layer of the position that is connected with the blade arrester on the lightning conductor removed, generally this length is about 50mm, adopts the increasing pad of A4 shape and the bolt of M12 * 20 that exposed copper cable is pressed on the metal copper billet at last.
And the described foam angle of wedge adopts the material consistent with the web sandwich, its thickness is the thickness of metal copper billet, the wedge degree ratio of the preferred foams angle of wedge is 1:5, that is to say along the metal copper billet to tilting to lay foam all around, make when vacuumizing of later stage poured into, can not produce non-essential displacement or distortion to arranging of lightning conductor, improve the formed precision of product when vacuumizing perfusion, that is to say and improve the once-through yield rate.
