- Summary:
- ABSTACT A new kind of Vacuum Generator Circuit
Breaker (VGCB) is introduced. The new VGCB have 2
breaks in each phase. One break is a Vacuum
Disconnector (VD) which can load large rated current
and the other one is a Vacuum Interrupter (VI) that can
interrupt large short circuit current. In open operation, it
is required that VD opens first and when the total
current passes through VI then VI opens. An experiment
that can simulate the situation is shown. In this
experiment sinusoidal current up to 24kA(r.m.s) is used
and the current can transfer from VD to VI successfully
each time. In addition to the experiment, a theoretical
analysis is made and a typical result is simulated. The
simulation result is similar to the experiment one. From
the experiment and theoretical results it is known that
the new vacuum generator circuit breaker design is
feasible.
