  • The vacuum circuit breaker is the heart of the Switchgear which consists of the Vacuum Interrupter, spring charged motor, closing solenoid, opening solenoid, anti pumping device, contact arm with isolating contact, buffer system, with-drawable trolley and multi pole control wiring plug & socket through which the circuit breaker is coupled with the control and protection circuit.
  • The With-drawable trolley mechanism establishes the mechanical connection between the panel and the circuit breaker.
  • Operating Mechanism: The mechanism employed in the circuit breaker is stored energy system that uses a charging motor to compress the closing spring. During the closing operation, the energy stored in the closing spring is released.
  • This allows the mechanism to close the vacuum interrupter contacts, compress the contact pressure springs, charge the opening spring and overcome frictional force. When the circuit breaker is opened, the energy stored in the opening and contact pressure spring is released and the vacuum interrupter contacts are opened.
