摘　　要：基于RLC参数模型,提出了变压器绕组断线谐振过电压情况下的绕组暂态特性分析方法,利用仿真软件计算和对比了绕组各单元及其匝间电压暂态响应,确定了容易受到铁磁谐振影响的绕组位置。Based on the RLC parameter model, a method for analyzing the transient characteristics of the transformer winding under the condition of resonant overvoltage is proposed. The simulation software is used to calculate and compare the transient response of the winding units and their turn-to-turn voltages. The position of the coil affected by magnetic resonance.
