Abstract

The authors discuss the decomposition of the dielectric SF6 in a high-voltage circuit breaker

and introduce the partial discharge methods with UHF and ultrasound technologies for the advanced high-voltage circuit breaker.Moreover

the methods for analyzing the purity of SF6 and detecting trace moisture are described

and the control indexes for the transfer of SF6 gas are provided.A high-voltage circuit breaker in operation is chosen for fault diagnosis with partial discharge detection method.Some suggestions about purity analysis of SF6 are offered in order to facilitate the application of the SF6 gas control indexes and the improvement of the partial discharge methods with UHF and ultrasound technologies.
