Product Description
VS1-12(VBM7) vacuum circuit breaker adopts fixed structure. It is mainly used in fixed switchgear and can be used separately to control and protect the transmission and distribution lines.
VS1 vacuum circuit breaker can operate frequently or break the short circuit current several times within the operating current range. Mechanical life up to 30,000 times, full capacity
Short circuit current can be broken 50 times.
VS1 vacuum circuit breaker is suitable for reclosing operation and has high operation reliability and service life.
VS1 vacuum circuit breaker(general type) uses vertical insulators to protect against climate effects; And in the maintenance and maintenance aspect, usually only need to do the operation between or sexual cleaning or lubricating.
VS1 vacuum circuit breaker(pole type) adopts solid insulation structure-integrated seal pole, realized maintenance free.
VS1 Vacuum circuit breakers can be installed in either stationary or extractable form in a switching cabinet and can also be installed on frames .
VS1-12 / M circuit breaker(with permanent magnet actuator) using vacuum arc extinguishing chamber, vacuum as arc extinguishing and insulation medium, arc extinguishing chamber has very high truth
VS1-12 VS1-12 Vacuum circuit breaker, voids, when the contact and static contacts are electrically divided under the action of the actuating mechanism, a vacuum arc will be generated between the contacts, and due to the special structure of the contact, an appropriate longitudinal magnetic field will be generated in the contact gap, which will cause the vacuum arc to remain diffusible and will spread evenly over the contact surface, maintaining a low arc voltage when the current is natural, The residual ion, electron and metal steam can be combined or assembled on the contact surface and shield over an order of magnitude of a microsecond, and the dielectric insulation of the interrupter break is quickly restored, resulting in the arc being extinguished and broken. As the vacuum breaker uses a magnetic field to control the vacuum arc, it has a strong and stable ability to break current.
