Abstract :
This paper studies the method of fault diagnosis in HVCB (high voltage circuit breaker), and discusses application of D-S (Dempster-Shafer) evidence theory in the HVCB´s faults. D-S evidence theory is discussed the problem of the validity, and out of work in the cases, a theory of evidence and the improved method were provided to resolve the D-S algorithm in realizing the conflict problem of the evidence in the process, a set of reliable fault diagnosis method is given in high voltage circuit breaker. Experimental results show that the new synthetic rules not only better integrate the advantages of retained correction model, avoid deficiency, and this combination rule can reach a better result.
