Rapid vacuum circuit breaker and control system thereof

[0033] figure 1 It is a schematic diagram of the principle of the rapid vacuum circuit breaker described in the embodiment of the present invention.

[0034]The embodiment of the present invention provides a fast vacuum circuit breaker, which is applied to a 500KV transmission line. The fast vacuum circuit breaker includes at least three unit modules 10 connected in series, and each unit module 10 includes two groups of circuit breaker assemblies connected in series 11. Each circuit breaker assembly 11 includes at least a first main circuit breaker, a second main circuit breaker and a voltage equalizing capacitor connected in parallel, and the first main circuit breaker is also connected in series with the first current sharing reactance and then connected in parallel with the voltage equalizing capacitor, The second main circuit breaker is also connected in series with the second current sharing reactance and then connected in parallel with the voltage sharing capacitor.
