Description

Cable outgoing line structure of permanent magnet synchronous wind driven generator
Technical Field
The utility model belongs to the technical field of the synchronous aerogenerator's of permanent magnetism technique and specifically relates to indicate a synchronous aerogenerator cable outgoing line structure of permanent magnetism.
Background
In the prior art, the output power of the permanent magnet synchronous wind driven generator is high and is megawatt, the outlet voltage of the generator is low and is mostly 690V grade, and the outlet current of the generator is high, so the quantity and the sectional area of the outgoing cables of the generator are large, but the structure of the generator is compact and the space is narrow, the insulation at the joint of the cables and the copper bars usually needs to be treated by spraying insulating paint, the cables are difficult to bend after the insulating paint is cured, and the installation process of leading out the cables becomes a technical problem.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome prior art's shortcoming and not enough, provide a synchronous aerogenerator cable outgoing line structure of permanent magnetism, can effectively solve the technological problem that the installation of generator outgoing cable is difficult.
In order to achieve the above object, the present invention provides a technical solution: a cable leading-out wire structure of a permanent magnet synchronous wind driven generator is characterized in that a cable joint is fixedly connected with a stator copper bar through a bolt, and is connected with a conducting ring of the generator through a wire lug and led out from a cable outlet on a cable outlet cover plate of the generator; the special-shaped structure is made into to the lug, by conducting ring installation part and cable installation part integrated into one piece, wherein, the conducting ring installation part is the slice, and it has the bolt mounting hole to open on it, can be through bolt fixed mounting on the conducting ring, the cable installation part is sleeve structure, the cable is that the cartridge is fixed in this sleeve structure, just there is the contained angle between conducting ring installation part and the cable installation part, through keeping corresponding angle and guaranteeing that after the cable installation has the lug, its position just can aim at the cable outlet on the cable outlet apron, avoids crooked cable to be qualified for the next round of competitions.
Compared with the prior art, the utility model, have following advantage and beneficial effect:
through the structural design optimization to the generator lug, the cable can be prevented from bending in the generator, the reliability of the cable is enhanced, meanwhile, the process of installing the generator cable is simplified, and the purposes of cost reduction and efficiency improvement are finally achieved.

Detailed Description
The present invention will be further described with reference to the following specific embodiments.
In the cable outgoing line structure of the permanent magnet synchronous wind driven generator provided by the embodiment, the cable 3 is fixedly connected with the stator copper bar by a cable joint through a bolt, because of the space limitation of the generator, the axial distance between the cable outlet cover plate 4 and the conductive ring 1 is very close, the space is compact, and as seen from fig. 1, the conductive ring 1 of the generator is arranged from left to right in fig. 1, however, in order to ensure the manufacturability of cable arrangement in the engine room of the wind generating set, when the cable 3 of the generator is led out from the cable outlet cover plate 4, three phases need to be arranged from top to bottom, as shown in fig. 2, the cable 3 of the generator is connected to the conductive ring 1 of the generator through the lug 2, as shown in fig. 1, the cable 3 is limited by the inner space, the sectional area of the cable 3 is large, the number of cables is large, and bending is difficult, so that the cable 3 cannot align with the cable outlet hole of the cable outlet cover plate 4. In order to solve the wire outlet problem of the cable 3, in the design, in this embodiment, the wire lug 2 is made into a special-shaped structure, as shown in fig. 3, the conductive ring mounting portion 21 and the cable mounting portion 22 are integrally formed, wherein the conductive ring mounting portion 21 is a thin sheet, a bolt mounting hole 211 is formed in the conductive ring mounting portion, the conductive ring mounting portion can be fixedly mounted on the conductive ring 1 through a bolt, the cable mounting portion 22 is a sleeve structure, the cable 3 is fixed in the sleeve structure in an inserting manner, an included angle a exists between the conductive ring mounting portion 21 and the cable mounting portion 22, and after the wire lug 2 is mounted on the cable 3, the position of the cable 3 can be just aligned with a cable outlet on the cable outlet cover plate 4 by maintaining a corresponding angle, so that the cable 3 is prevented from being bent to be outlet.
The above scheme of this embodiment has implemented and has used on 3MW aerogenerator, and after the design improvement, the cable mounting process is more convenient, simplifies, has improved the installation effectiveness of generator cable, has practical application and worth promoting.
The above-mentioned embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, so that all the changes made according to the shape and principle of the present invention should be covered within the protection scope of the present invention.
