Transformer substation uses monostable permanent magnetism breaker in station

The utility model relates to a transformer substation uses monostable permanent magnetism breaker in station belongs to a transformer substation station and uses the equipment field, and in particularto uses the monostable circuit breaker to a transformer substation station, include: frame, vacuum interrupter, moving contact, flexible coupling, operation insulator, permanent magnetic mechanism, permanent magnetic mechanism casing, move iron core, mechanism's coil, separating brake spring, contact pressure spring, a binding post, through the utility model discloses a design promotes output characteristic, and the opening range who reduces the explosion chamber makes the utility model discloses the clearance between open contacts of circuit breaker reduces, has reduced the stroke of work original paper like this, has reduced the utility model discloses an operate time makes the reaction rate faster. Simultaneously the utility model discloses the installation nimble can the formal dress,flip -chip and side dress
