本文针对改制谐波励磁发电机时,由于原产品型号或生产年代不同而产生的性能差异较大的情况,提出根据发电机铁芯的极弧系数αP 进行电枢绕组结构选择,给出了进行谐波绕组可靠匝数计算的实用公式 W_(3K)=(W_1·U_(BH)·(δ_m/a)~(1/2))/(m_3·U_1·αp~3·K_(r3)),并讨论了凸极铁芯参数对谐波励磁发电机性能的影响及其处理方法.
In this paper, based on the pole arc coefficient αP of generator core, the structure of armature winding is proposed to solve the problem that when the harmonic excitation generator is reformed due to the different performance of original product model or production age, Practical formulas for calculating the number of reliable turns of harmonic windings W_ (3K) = (W_1 · U_ (BH) · (δ_m / a) ~ (1/2)) / (m_3 · U_1 · αp ~ 3 · K_ (r3)) The influence of the salient pole iron core parameters on the performance of harmonic excitation generator and its processing method are also discussed.
