Description
Technical Field
The invention belongs to the technical field of stator winding manufacturing, and particularly relates to a winding method of a modularized stator winding of a direct-drive wind driven generator.
Background
The direct-drive wind driven generator is huge in size, and causes great difficulty and increase in cost for transportation and maintenance. In order to reduce the transportation and maintenance cost of the direct-drive wind driven generator, the wind driven generator is changed into a modularized structure, so that the transportation and maintenance are convenient, and the development trend of the direct-drive wind driven generator is realized.
The stator winding of the existing direct-drive wind driven generator is a preformed stator coil, the section of a wire for winding the stator coil is rectangular, namely, the stator coil is vertically wound in a flat mode, and then the stator coil is embedded into a slot of a stator core. The modularized motor stator winding structure is a concentrated winding structure that leads are vertically wound on a single iron core in a flat mode, and then iron core coils are arranged on a stator support, namely, scattered slot-by-slot coil inserting is changed into integral iron core coil assembling.
In the prior art, the section of a wire for winding a stator coil is usually circular, and the existing winding technology is used for winding a stator winding of a direct-drive wind driven generator, so that the defect is overcome.
First, the end wire skew, inter-turn gap is large: the existing winding technology can only meet the condition that the iron core with baffles at the periphery is wound, the baffles at the periphery are all arranged, a lead cannot have a large inter-turn gap due to extrusion during winding, as shown in fig. 1 and 2, but when the stator winding of the direct-drive wind driven generator is wound, the stator iron core is in a strip shape, a straight line part in the middle and semi-cylindrical ends at two ends are integrally formed, side wall baffles are arranged at two sides of the straight line part of the stator iron core, and are higher than the outer wall of the straight line part of the stator iron core, so that an installation groove for embedding the stator coil is formed at the straight line part of the stator iron core, and the semi-cylindrical ends are easy to topple or deflect during winding, as shown in fig. 3.
Second, the stator winding straight line segment is long and the width dimension cannot be guaranteed: the existing coil winding technology can only meet the requirement of coil winding with the linear length smaller than 400mm, and if the linear length of the coil exceeds 400mm, the middle part of the coil can be expanded and deformed, so that the deformation of the coil span (in the width direction) is larger than 5 mm.
The third point is that the winding cannot be wound and the section of the winding wire is rectangular and is in a vertical flat winding structure: in the prior art, only the wire with a circular section can be wound on the iron core, as shown in fig. 2, if the wire is rectangular in section and the narrow side of the rectangle is in contact with the bottom of the iron core (vertical flat winding is shown in fig. 4), when the wire is wound by using the prior art, the wire can be deflected and toppled over due to the fact that the wire cannot be fixed during winding, and the winding cannot be realized.
Fourth, when the prior art is used for winding, the R part in the coil end is thickened by about 0.4mm, the R angle of the end is thickened to cause large inter-turn gaps of the straight line part, and the insulation performance is poor.
Disclosure of Invention
The invention aims to provide a method for winding a wire with a rectangular section on an iron core, which can ensure that the wire does not deviate or incline during winding, solve the problems of thickening at two ends of a coil, overlarge inter-turn gap and shorter linear length during winding, meet the requirement of insulativity and furthest reduce deformation.

Fifthly, when the wire is wound to the right semi-cylindrical end head (14) again, the right cylinder assembly (6) retreats, the right inserting piece (15) is taken out, and the right inserting piece (15) is padded between the front turn of wire and the current wire to be wound; when the wire is wound to the left semi-cylindrical end (13) again, the left inserting piece (19) is taken out, and the left inserting piece (19) is padded between the front turn of wire and the current wire to be wound; repeating the actions of the third step and the fourth step until all turns of the wire are wound, and beating and shaping the wound turns by using a beating plate (18) in the winding process to enable the wire to be attached to the bottom of the mounting groove of the stator core (1) until the winding of the stator coil is completed;
and step six, cutting off the lead after the winding of the stator coil is completed, integrally demounting the winding of the stator core (1), fixing two sides of the linear part of the coil by using a clamping plate (16) and at least two U-shaped clamps (17), and shaping the linear part of the coil.
2. The method of claim 1, wherein in the second step, the wire tension is adjusted to a damping of 50%.
