Perform periodic inspection of the internal parts of an SF6 circuit breaker to ensure that mechanical parts are in proper operating condition.
SF6 circuit breakers use sulfur hexafluoride (SF6) gas to quench the powerful arc that is created when a breaker interrupts a fault. Using SF6 offers a smaller footprint, higher operating voltages than vacuum technology, and relatively low maintenance, but it’s important to perform periodic inspection of the internal parts of an SF6 circuit breaker to ensure that mechanical parts are in proper operating condition.
A power generation customer recently needed to replace the operating mechanism on one of the phases of their ABB 145 SF/P 63 SF6 circuit breaker. Circuit Breaker Sales Northeast and Premier Power Maintenance were called in to replace the mechanism and perform preventive maintenance and testing. Just three days after the circuit breaker went out of service, the customer was back online.
Beyond regular maintenance, our partners at Vacuum Interrupters can refill SF6 interrupters, repair SF6 breaker pole assemblies, and replace SF6 interrupters.
