VS1-12/1250A Casting Resin Insulation With High Voltage Indoor Vacuum Circuit Breaker
1. Keep the core at the upper and lower limits without any mechanical locking. When there is an action signal, the current in the closing or separation coil produces a magnetic potential.
2. The magnetic field produced by the coil and the magnetic field produced by the permanent magnet is superimposed and synthesized by the magnetic field. The magnetic core, together with the driving rod fixed on it, is operated by the synthetic magnetic force and the switch body is turned on and off at the specified speed. This mechanism is called a two-bit bistable structure because the moving iron core can be maintained without any energy consumption at the two ends of the journey. In the traditional electromagnetic mechanism, the moving core is kept at one end of the journey by the action of a spring, while at the other end of the journey, it is protected by a mechanical latch or electromagnetic energy. From the above, the permanent magnet actuator is a special combination of electromagnet and permanent magnet to achieve the traditional circuit breaker operating mechanism of all functions: permanent magnet instead of traditional .
3. 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
4. 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.
