6 FAQs about [Samoa vacuum circuit breaker energy storage]

What is a vacuum circuit breaker (VCB)?

What was the first vacuum circuit breaker?

By the mid-1960s, General Electric (GE) Corporation (USA) developed a 15 kV/1.2–12 kA vacuum circuit breaker (VCB) which was the first VCB product worldwide. At the same period, Xi’an Jiaotong University developed the first three-phase vacuum switch in China in 1965, which was with 10 kV and 1500 A.

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 happens if a fast vacuum switch reaches a contact gap?

The contact gap distance of the fast vacuum switch keeps increasing until it approaches a contact gap that could withstand the transient interruption voltage of the DCCB, the power electronic switches turn off, and the fault current further commutates into the energy dissipation circuit and decays to zero.

Can a fast vacuum circuit breaker interrupt a fault current?

Fast vacuum circuit breaker can interrupt a fault current in the first half-cycle. Fast vacuum switching technology is promising for accurate controlled switching. Future power systems could benefit from the application of fast vacuum switches. Vacuum switching technology is changing the future of power systems.

How can vacuum switching improve the transient stability of power networks?

This can thus greatly enhance the transient stability of power networks in the presence of short-circuit faults, especially for ultra- and extra-high-voltage power transmission lines. Third, based on fast vacuum switching technology, various brilliant applications emerge, which are benefiting the power systems.
