VS1-12 630A-1250A Epoxy Resin Insulation With High Voltage Indoor Vacuum Circuit Breaker
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.
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 .
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.
