Study of SF6 circuit breaker fault diagnosis expert system

Abstract

Set the expert analysis and diagnose system of the moisture content in SF 6 .make good use of the manual work blur NN technique and illegibility technique and expert system technique to deal with the illegibility and uncertainty in the course of analyzing of moisture content in SF 6 switch and make good use of the superiority of all kind of the reasoning method, and get over the shortage of existent ,so that we can find the answer of the question in the great extent ,and improving the nicety rate of the diagnose and the reliability of current analysis. The overall structure of the system design scheme This system mainly consists of the following parts: man-machine interface, inference engine, explanation module, learning module, neural network module of dynamic database module, knowledge base module, knowledge database management module etc. System structure diagram is shown in Fig. 1.
