The Importance Of Vacuum Processing In Sf6 Circuit Breaker Operating Mechanisms

Residual gas or impurities in the sealed cavity sf6 circuit breaker operating mechanism can reduce the system's insulation level and may cause arcing, insulation breakdown, or mechanical jamming during equipment operation. Thoroughly removing residual gas from sf6 circuit breaker spring mechanism using a vacuum pump helps remove air, water vapor, impurities, etc., thus providing a low-impurity, low-humidity environment for subsequent SF6 gas filling or maintenance work.
