Q: How is 11kv vacuum circuit vcb breaker switch indoor different from SF6 or oil circuit breakers?
A: The 11kv vacuum circuit vcb breaker switch uses vacuum interrupters to extinguish arcs, which means no oil leakage, no greenhouse gas emissions, and far less maintenance. It is cleaner, safer, and offers longer contact life.
Q: What are the maintenance requirements of a 11kv vacuum circuit vcb breaker switch?
A: Routine inspections are recommended, such as checking contact resistance, mechanical operations, and insulation. However, because vacuum interrupters are almost maintenance free, the 11kv vacuum circuit vcb breaker switch requires very little servicing compared with oil insulated type or SF6 gas insulated type circuit breaker.
Q: Is 11kv vacuum circuit vcb breaker switch suitable for smart grid or remote monitoring?
A: Yes. The 11kv vacuum circuit vcb breaker switch can be combined with protection relays, remote control, and communication devices, of which the components can support SCADA systems and smart grid automation, providing real time monitoring and remote operation.
