24kV high votage Indoor Vacuum Circuit Breaker with 24kV Switchgear Equipment
Description
VS1-24 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
VS1-24VS1-24 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.
