The static end support is connected with a static contact of the vacuum arc-extinguishing chamber. A moving contact of the vacuum arc-extinguishing chamber is connected with the conductive connection. The transmission system comprises a connection plate capable of rotating round a three-phase rotating shaft, an insulation pull rod, a crank arm and a contact push rod capable of driving the moving contact of the vacuum arc-extinguishing chamber to perform horizontal movement in the vacuum arc-extinguishing chamber. The vacuum arc-extinguishing chamber is adopted to be a main part of the breaker. The vacuum circuit breaker has good on-off ability and long useful life and avoids problems caused by that an insulating oil or SF6 is used to be an insulation medium. The operating mechanism adopts modularization design. A tripping mechanism and an opening-closing mechanism are assembled in the same box body together. The structure is compact, operation is reliable and installation and maintenance are convenient.
