China's Gas-related Standards For Sf6 Circuit Breaker Operating Mechanisms

To ensure the high performance of sf6 circuit breaker operating mechanism, my country's standards stipulate that its gas moisture content should be kept below 300ppm (volume ratio). This standard not only effectively prevents the degradation of electrical insulation performance due to excessive gas moisture content, but also ensures the reliability and safety of the equipment during long-term use. sf6 circuit breaker spring mechanism is an important protective device in the power system, and the gas quality of its operating mechanism is crucial. Excessive moisture content can cause problems such as breakdown and corrosion of electrical equipment.
