Fault Diagnosis Technology of Power Capacitor Insulation Based on Fuzzy Theory Algorithm
摘要
Abstract
There are many kinds of faults in power capacitors, fault phenomena are ambiguous, and the relationship between the cause of the fault and the symptoms of the fault is complex and complicated, and it is very easy to see misdiagnosis and missed diagnosis in equipment fault diagnosis. Based on the analysis of the common faults of power capacitors, this paper analyzed and compared the sensitivity of the insulation fault status, determined the parameters that reflect the insulation fault under different fault conditions, and finally proposed an insulation fault diagnosis method based on fuzzy theory. The insulation fault fuzzy diagnosis model is based on insulation moisture content and aging degree as the output of power capacitor insulation status. The fault membership degree vector was obtained by the fuzzy operator, so as to diagnose the moisture content and aging degree of the insulation.The feasibility of the fuzzy diagnosis method was verified by analyzing the power capacitor anatomy experiment.关键词
