Abstract

In order to quickly and accurately forecast

analyze

and diagnose faults in circuit breaker

and determine fault nature

type

cause

and location

a diagnosis model of HV SF6 circuit breaker based on fuzzy diagnosis theory was presented. According to the analysis and statistics of the common failures

the on-line monitoring items of SF6 circuit breaker as well as the relationship between the characteristic parameters and the failures of CB was determined.

Subsequently

the failures array

failure symptoms array and fuzzy relational matrix were established

and the optimum fuzzy operator and diagnosis rules were given. A case study verified the convenience and the reliability of the algorithm.
