Vacuum Circuit Breaker

Abstract: The present utility model relates to a vacuum circuit breaker. The vacuum circuit breaker comprises an operating mechanism (2). The vacuum circuit breaker further comprises a plurality of vacuum interrupter modules (3). The operating mechanism (2) is in driving connection with the plurality of vacuum interrupter modules (3). Each vacuum interrupter module (3) comprises: a housing (4); a vacuum interrupter chamber (6), accommodated inside the housing, and provided with a static contact and a moving contact oppositely arranged; a contact support assembly (7), accommodated inside the housing and connected to the moving contact in the vacuum interrupter chamber (6). The operating mechanism (2) is in driving connection with the contact support assembly (7). The inner wall of the housing is matched with the vacuum interrupter chamber (6) and the contact support assembly (7) to form a concave-convex structure, and is formed with connection openings corresponding to the static contact, the moving contact and the contact support assembly (7).
