本文分析了压缩机电机匝间短路的原因，并用物理等效电路和有限元仿真计算，得出电机匝间短路时电流的变化及特点，证明了匝间短路形的大电流是造成短路绕组烧损的直接原因。%The present study analyzed the causes of turn-to-turn short circuit of compressor motor. And the variations and the characteristics of current during motor turn-to-turn short circuit were obtained via physical equivalent circuit and FEM simulations and computations. It is found that the big current formed during turn-to-turn short circuit is the direct cause of burnout of the short-circuited windings.
