摘要
对一台220kV电力变压器分相进行了不同程度的突发短路试验,通过对比试验前后的短路阻抗测试、频率响应测试和绕组电容量测试数据,分析了绕组变形测试方法和相关规程的有效性和局限性。
In this paper, different grade sudden short-circuit test is applied on every phase of a 220kV power transformer. The diagnosis validity and limitation of transformer winding deformation test and standard are analyzed by comparing the data of short-cir- cuit impedance test, frequency response analysis and winding capacitance test before and after sudden short-circuit test.
