Why Must The Adsorbent Be Replaced During The Disassembly And Maintenance Of The Sf6 Circuit Breaker Operating Mechanism?

When disassembling and repairing sf6 circuit breaker operating mechanism, it is necessary to open the casing and expose the internal components. At this time, the original adsorbent, due to long-term operation, is nearing saturation, and its ability to capture moisture and impurities has decreased, potentially failing to meet the requirements of the internal gas environment. Replacing the adsorbent with a new one, rather than continuing to use the old one, can quickly restore the internal gas control conditions and reduce the impact of residual moisture and impurities on subsequent operation.

During the overhaul, the adsorbent material itself may also change its properties due to temperature and pressure variations and prolonged contact with impurities. The introduction of the new adsorbent helps maintain the dryness and cleanliness level inside unit sf6 circuit breaker spring mechanism, thereby supporting the improvement of the internal environment during reassembly after maintenance.
