摘要(Abstract):
针对常用于充油变压器绝缘故障诊断的三比值法的局限性,提出了模糊三比值故障诊断法。仿真分析表明,模糊三比值法判断故障类型的准确率更高。
Fault diagnosis method of fuzzy three-ratio is proposed according to the limitations of three-ratio method which is commonly used for the diagnosis of insulation fault in oil-filled transformer.The simulation results indicate that the method of fuzzy three-ratio can provide higher accuracy in fault type judgment.
