Abstract
This paper makes a statistical analysis to the failures of actuators of 110~500?kV SF 6 circuit breakers in Chinese power system during 1989 to 1997. It also analyses the factors that influence the operational reliability of actuators. It then introduces development and features of the breaking principles of SF 6 circuit breaker with its operating mechanism. Finally
it discusses the ways to improve the reliability of actuators and the issues to be noticed when it is applicated.
