Product Description

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.
