Abstract

Fuzzy pattern recognition model is applied to electrical apparatus reliability evaluation. Based on dual-pole fuzzy pattern recognition model, the method for electromagnetic relay´s reliability dynamic and synthetic evaluation is developed. The characteristics vector, indicating the reliability of the electromagnetic relay, consists of contact resistance, open circuit voltage, contacts making time and contacts breaking time. Four performance parameters can be synthetically considered by this method, and the reliability can be accurately shown as the value of fuzzy membership degree.
