Why Is High-purity Nitrogen Injected Into The Operating Mechanism Of The Sf6 Circuit Breaker And Subjected To Multiple Venting Processes?

High-purity nitrogen gas, with a purity exceeding 99.99%, is introduced into compartment sf6 circuit breaker operating mechanism to ensure operational stability and reliability. The introduction of high-purity nitrogen effectively removes impurities and moisture from compartment sf6 circuit breaker spring mechanism, preventing adverse effects on electrical equipment. Through venting and repeated treatment twice, the system is further cleaned and purified, ensuring optimal results at every stage of the nitrogen filling process.
