ZW8-12C Medium Voltage High Voltage Outdoor Vacuum AC Circuit Breaker
The division of circuit breaker, closing operation can be manual or
electric operation and remote control operation. It can be used for
power distribution automation with intelligent controller. It can
also be used with overlapping controller to form automatic
recombine and segment divider.
The circuit breaker may be installed with a two-phase or
three-phase current Transformer for overcurrent or short-circuit
protection, and may also provide current acquisition signals to the
intelligent controller; According to the requirements of the user,
the current Transformer for metering can be installed.
Function:
A load switch is an electrical switch between an isolation switch
and a circuit breaker. It has a simple arc extinguishing device
that can cut the rated load current and a certain overload current,
but can not cut the short circuit current.
Principle:
Under the action of the separation spring, the spindle rotates
clockwise, on the one hand, the piston moves upwards through the
crank slide mechanism, compressing the gas. On the other hand, two
sets of four-rod drive system make the main gate knife open first,
then push the arc cutter to open the arc contact, the compressed
air in the cylinder through the vent to extinguish the arc.
