Abstract

The invention relates to a large and permanent magnet wind turbine generator scatteredly embedded winding stator insulation mechanism which comprises a slot inside insulation component and an end part insulation component. The slot inside insulation component comprises a slot wedge, a slot insulation, a slot bottom filler strip, a middle insulation and a scatteredly embedded wire winding. The slot wedge is arranged on one end of the scatteredly embedded wire winding. The scatteredly embedded wire winding is composed of an upper winding and a lower winding. The middle insulation is arranged between the upper winding and the lower winding. The slot insulation is arranged on the outer side of the scatteredly embedded wire winding. The slot bottom filler strip is arranged at the lower part of the slot insulation. The end part insulation component comprises end part insulation pieces between phases, end part insulations, lashing ropes, soft end bands and a winding end part sealing piece. The end part insulation pieces between phases are arranged between windings at the end parts of a generator. The end part insulations wrap the outer sides of the windings. The winding end part sealing piece is arranged on the non wire outlet end of the scatteredly embedded wire winding. The soft end bands are lashed on the outer side of an end part insulation through the lashing ropes. Compared with the prior art, the mechanism provided by the invention has the advantages of strong anti halo ability, good insulation performance, less dielectric loss, good dielectric strength performance and the like.

Description

technical field [0001] The invention belongs to the field of motor insulation, and in particular relates to a large-scale permanent magnet wind power generator scattered embedded winding stator insulation mechanism. Background technique [0002] The development and utilization of wind energy is developing very rapidly, and the application technology of wind power generation has become increasingly mature. After the Fukushima nuclear power plant incident in Japan, the global wind power market has become a new focus. [0003] The rapid development of wind power in China is mainly driven by: government support and encouragement, increased demand for existing and new wind farms, and advantages in material costs. With the further improvement of the economics of wind power and the gradual resolution of the problem of wind power grid integration and consumption, and with the strong support of government policies, China will continue to lead the development of wind power in the wor...
