摘要
频率响应分析法只能检测变压器绕组变形故障 ,而不能实现对局部放电故障的定位。在频率响应分析法的基础上 ,对变压器绕组的模拟电路进行了分析研究 ,利用绕组在一定频率范围内呈现纯容性的特性 ,给出了实现变压器绕组局部放电故障定位的新思路。经仿真计算 ,验证了这种局部放电故障定位的有效性。
Frequency response analysis can be used to examine distortion fault in transformer windings,but can't perform partial discharge Location. Based on frequency response analysis, the simulative circuit of transformer's winding was analyzed in this paper.According to the pure capacitive characteristic in current frequency range in transformer winding,a new method was given to realize locate the partial discharges fault in transformer winding.The method is proved to be effective by simulative experimentation.
