Analysis Of Adhesive Treatment For Improving Maintenance Quality Of Sf6 Circuit Breaker Operating Mechanisms

For flange gaps at point sf6 circuit breaker operating mechanism, 703 sealant is applied. This sealant, in conjunction with other lubricants and sealing materials, seals the gaps on the outer side of the flange mating surface. This practice originates from field maintenance experience and industry guidelines in the high-voltage switchgear industry. The sealant forms a continuous barrier between the metal contact surfaces, reducing the possibility of impurities entering through tiny gaps.

In practice, after cleaning metal residue, oxide layers, and oil stains from the flange surface, maintenance personnel apply 703 sealant to the flange gaps at point sf6 circuit breaker spring mechanism, either by dotting or along the gap line. This adhesive material, after curing, forms a flexible sealing layer that, in conjunction with the surrounding lubricant and sealing ring, provides a durable barrier effect and adapts to the dynamic state of the SF6 circuit breaker under changes in temperature and pressure.
