摘要
Abstract
The paper introduces a 220 kV transformer windings breakage fault which caused by low-voltage switch cabinet inner short-circuit. In order to check the damage extent of the windings, winding resistance test, oil chromatographic analysis and frequency-scan response analysis (FRA) are implemented. The conclusion reached by analyzing the test data is that the low-voltage windings of the transformer is deformated and the phase C winding is broken, then the conclusion is proved to be corrert by disintegrate result. At last, the reasons of the fault are comprehensive analyzed, and the preventive measures are given.关键词
