The Operating Mechanism Container Of An Sf6 Circuit Breaker Must Be Replaced After Disassembly.

During the maintenance of high-voltage switchgear, once the sf6 circuit breaker operating mechanism container is completely or partially disassembled, it often needs to be replaced with a new enclosed unit according to the manufacturer's standards. This replacement requirement stems from the operating condition of the internal components.

The sf6 circuit breaker spring mechanism container undergoes rigorous sealing and gas treatment processes at the factory. The SF6 gas and related materials such as adsorbents inside provide a foundation for stable insulation and arc extinguishing performance. During long-term operation, the adsorbent's performance significantly degrades after capturing trace amounts of moisture and impurities. If the aged medium is continued to be used after the container is disassembled and reassembled, it will be difficult to meet the stringent internal environmental requirements of high-voltage switchgear.
