What are the characteristics of using high purity sulfur hexafluoride in circuit breakers?

　　High insulation level.Sulfur hexafluoride at 0.3MPa air pressure,can pass various insulation tests and has a lot of margin.After the cumulative breaking current is 3000kA,each fracture can withstand the power frequency voltage of 250kV for 1 minute under the pressure of 0.3MPa.When the high-purity sulfur hexafluoride is reduced to zero,the power frequency voltage of 166.4kV5 min can still be tolerated.

　　Good sealing performance.High purity sulfur hexafluoride gas has low water content.The arc extinguishing chamber,resistance and pillar are divided into independent gas compartments,which can be installed on site without opening,and connected with automatic joints after installation.Convenient installation and maintenance,but also can prevent dirt,moisture into the circuit breaker.
