    Abstract: Introduction was made to the principle of eddy current forced fast vacuum circuit breaker. Analysis was made to the technologies used and problems existing including arc and resonance elimination, fault line selection and electric shock protection, grid short-circuit
current limitation, series compensation and transformer direct current magnetic bias suppression etc technologies in distribution network at present. According to the characteristic of fast vacuum circuit breaker, the solution method of those problems was proposed. This paper expounded the structure, experiment and application of the relevant device. The further application of the circuit breaker is prospected.
    Key words: fast vacuum circuit breaker; electric shock protection; short-circuit current limitation; series compensation; DC magnetic bias
