VS1(VBM7)-12 side mount high voltage Indoor Vacuum Circuit Breaker with power switchgear 630A-1250A
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.
VS1-12(VBM7) 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.
VS1-12(VBM7) 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.
VS1-12(VBM7) vacuum circuit breaker(pole type) adopts solid
insulation structure-integrated seal pole, realized maintenance
free.
VS1-12(VBM7) Vacuum circuit breakers can be installed in either
stationary or extractable form in a switching cabinet and can also
be installed on frames .
VS1(VBM7)-12 side mount
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.
