4 FAQs about [Yueneng energy storage vacuum circuit breaker]

Are vacuum circuit breakers qualified as generator circuit breaker (GCBs)?

Circuit breakers employing vacuum technology fulfil all defined requirements to be qualified as Generator Circuit Breakers (GCBs) according to the above mentioned standards.

Do generator circuit breakers increase the availability of power plants?

In order to ensure such reliability, the availability of the power plant must be high. The generator circuit breakers (GCB) are proven to increase the availability of power plants in general. However, in regards with PSPPs the challenges on the GCBs are different than conventional power plants.

How does a medium voltage breaker work?

Medium voltage breakers employ the principle of current-zero-interruption; means a zero crossing is required for the breaker to interrupt the current. In case of unfavourable generator parameters, the current zero crossings can delay for several cycles.

What are opening and closing buffering components in fast vacuum switches?

The opening and closing buffering components in the fast vacuum switches are adopted to lower down the opening and closing velocities and moderate the impact force when the movable contact of the VI approaches the open or close position.
