摘要
Abstract
A 110 kV substation main transformer in Bayannur region of Inner Mongolia fault tripping due to bad weather conditions, cause the circuit breaker tripping on the three side of the transformer, differential protection and the weight of the gas protection action. To the accident, use oil chromatographic analysis, the winding deformation and dc resistance test, capacity rate analysis methods such as judge the damage, the damaged degree of the main transformer, to verify the fault and found that the test results are consistent. Several ways used in this paper provide a reference for other substations to accurately diagnose transformer faults in future.关键词
