The Seals Of The Operating Mechanism Of An Sf6 Circuit Breaker Must Never Be Cleaned With Gasoline!
When overhauling sf6 circuit breaker operating mechanism, special attention must be paid to the handling of seals. For seals used with sf6 circuit breaker spring mechanism, organic solvents such as gasoline or chloroform must not be used during cleaning. Metal parts can be treated with cleaning agents or gasoline if necessary, but the parts of the seals that come into contact with SF6 gas are critical sealing elements.
If seals come into contact with gasoline or chloroform, it may cause material aging, hardening, cracking, or minor deformation, thereby reducing sealing performance. Once the seal fails, it may cause SF6 gas leakage, posing a threat to the safe operation and insulation performance of the circuit breaker. Therefore, the correct approach for seals is to replace them directly; never use gasoline or other solvents for cleaning.
