Sulfr hexafluoride Circuit Breaker Types, Working Principles Maintenance.

Feb 20, 2021 · Maintenance of Sulfr hexafluoride circuit breaker. A common problem with an sf6 gas circuit breaker is gas leakage. When leakage occurs, the gas pressure decreases. This reduces the quenching ability of the circuit breaker. To avoid this, always check your breakers often. You can check that via the pointer of the gas gauge. If the gauge shows a decrease in gas pressure, subject it to a gas leakage test.
