摘要
在所有变压器故障中,变压器绕组损坏所引起的变压器故障的故障率是最高的。在介绍绕组变形机理的基础上,阐述了短路阻抗法、低压脉冲法和频率响应法三种绕组变形测量方法,并对比分析了这些方法的优缺点。
In transformers,the fault rate of transfomer fault caused by the transformer winding hreakdown is the most.On the baiss of presenting the winding tranform mechanism,the paper explains three winding transform measuring methods of short-circuit impedance method,low-voltage impulse method and frequency response method,and analyzes and compares strong and weak pionts of these methods.
