Advantages of Operating Mechanism
Faster response time:
When a system fault occurs, the operating mechanism must actuate the circuit breaker to open within a very short time (typically within tens of milliseconds) after the relay protection device issues a signal. This rapid operation quickly interrupts the fault current, minimizing damage to power equipment and shortening grid outage duration.
Improved reliability:
The operating mechanism is designed to operate accurately even under extreme conditions, such as the significant electrical and mechanical stresses experienced during a short-circuit fault.
Good environmental adaptability:
Its performance is less affected by ambient temperature and is more stable than hydraulic or pneumatic mechanisms.
Relatively simple maintenance:
No complex oil or air circuits are required, resulting in high reliability and minimal maintenance.
Instructions of operating mechanism
Energy Storage Operation:
After the mechanism is mounted on the cabinet, insert the dedicated handle into the operating shaft located on the lower right side of the mechanism. Turn the handle clockwise until it clicks (the energy storage indicator shaft will push the energy storage microswitch to the fully closed position), and energy storage is in place. For electric operation, the mechanism automatically charges energy upon power-up. Once energy storage is in place, the motor circuit is disconnected, and the energy storage is maintained, waiting for energy release to close the circuit breaker (during electric operation, ensure that the secondary circuit is correct).
Closing Operation:
Press the green button to momentarily release the closing energy, and the mechanism pushes the circuit breaker to close the main circuit. For electric operation, energize the closing solenoid coil, which momentarily releases the stored energy. The mechanism pushes the circuit breaker to close the main circuit and simultaneously charges the opening spring (energy storage can continue at this point, but the anti-error interlock prevents further closing).
Opening Operation:
Press the red button to momentarily release the opening energy, and the mechanism pushes the circuit breaker to open the main circuit. During electric operation, the tripping electromagnet coil is energized, the tripping electromagnet acts instantaneously to release the stored energy, and the mechanism pushes the circuit breaker switch to complete the main circuit trip.
