摘要
该文在分析 3Y/3Y 换相变极局限性之后,提出一种新的交流电机换相变极法-2△/3△变极,并阐述了其换相原理。这种变极法用于稍宽极比变极电机较 3Y/3Y 变极优越;文中分析了 2△/3△网络接法时的感应电势、负载电流、相电压的分布以及激磁的合成;并以常用风机变极方案为例,把 2△/3△变极方案与 3Y/3Y 变极方案作了比较。
In this paper ,the limit use of 3Y/3Y change-pol is analyzed, then a new commutating method for change pole t variable-pole machine-2?/3? -change-pole is presented, an its commutating principle is discuussed. The presented metho is used for some-wide-ratio change-pole machine superior t 3Y/3Y-change-pole. The distributions over 2?/3? -network o the inductive electromotive foce, load current, phase voltag and the excitation merging are anelyzed in the paper. Then tak the blast change-pole machine as example, the plan of 2?/3? change-pole and the plan of 3Y/3Y-change-pole are compare in the paper.
