Circuit breakers play an extremely important role in power systems, and Sulfur Hexafluoride (hereinafter referred to as SF6) gas is the medium for the main functions of circuit breakers, and it has the functions of insulation and arc suppression. After the excavation of SF6 and reports on its application in electric power equipment and recently related literature, inspiring the author to summarize - the unique characters of SF6 and the arc suppression and operation principle, and explained some proper terms on the nameplate of the circuit breaker, all those combine an article, which can be prone to understand, at the same time it is easy to navigate of international journal on the website. In addition, for the abnormal situation of the connecting circuit breaker between the two busses in the substation, the "time constant" formed by the equivalent resistance and inductance value of the DC component of the zero-sequence fault current is related to the breaking time of the circuit breaker. Finally, combined above mentioned character with the points that must be paid attention to maintenance and being repaired on SF6 breaker in during, those things will be compiled into an article, which can be used as a reference for technical personnel in the field of power engineering.
