Outgoing line device, stator, generator, wind generating set and wiring method

Abstract

The invention provides an outgoing line device, a stator, a generator, a wind generating set and a wiring method. The stator includes a stator core with a yoke portion and a tooth portion, a stator winding disposed on the tooth portion, and a stator support for supporting the yoke portion, the stator support comprises an extension part extending beyond the axial end of the stator core, the outgoing line device is fixed on the extension part and comprises a fixing seat, wherein the fixing seat is positioned on one side of the extension part facing away from the tooth part, and the fixing seat is provided with an outgoing line hole; an outgoing line plate, the outgoing line plate is fixed on one side of the extension part away from the tooth part with respect to the extension part, and the outgoing line plate comprises outgoing line holes, each outgoing line hole is connected to the corresponding cable hole on the fixing seat, the cable leading out from the stator winding extends in thecircumferential direction, and then passes through the cable hole and draws out from the outgoing line hole. The outgoing line device not only has a simple structure, but also makes the wiring structure more compact.

Description

technical field [0001] The present invention generally relates to the field of ancillary equipment for wind power generation. Specifically, it relates to a wire outlet device for a stator, a stator, a generator, a wind power generator set and a wiring method. Background technique [0002] The stator windings are usually led out through end rings or directly to the motor cabinet, which can provide power to the stator windings or receive power from the stator windings. However, large electric machines (for example, generators for wind turbines) have large dimensions for both the stator and the stator windings. If the stator winding is directly drawn out, the lead-out end of the stator winding will occupy a larger space, which will lead to a larger size of the motor. If the stator windings are led out using end rings, the cost of the motor will increase. Contents of the invention [0003] Therefore, it is an object of the present invention to provide a cable outlet device ...
