| 摘 要： | 以六相八极双绕组发电机为例,分析了半周连续分布和交替极下分布的两种不同绕组形式电机在其中一套Y绕组故障时,电机空间磁场的不对称产生的各次空间谐波磁场,研究了各次谐波旋转磁场在励磁线圈上产生的感应电势。结果表明,在定子双绕组布置方面,交替极下分布的绕组比半周连续分布的绕组对励磁绕组产生的过电压较小,此结论可推广至多Y绕组电机。

| Abstract: | This paper deals with the space magnetic hamornics in two typical kinds of dual-winding generator due to dissymmetry of magnetic field when one of two windings in this generator is short circuit.The induced electrical motive force in the field winding corresponding to magnetic hamornics was studied.On the basis of that,the advantages and disadvantages of these two windings were compared at last.The result shows that dual-Y winding generator with symmetrical winding is superior to those with dissymmetrical winding.This conclusion can be extended to multi-Y winding generator. |
