VCB Spring operation mechanism for vacuum circuit breaker switchgear

Model:

Description:

The Spring operation mechanism adopts high-precision machining and professional design, which has the characteristics of reliable operation, compact structure, small volume, smooth operation, and long service life. When the power supply fails, it can still complete the operation of disconnecting and closing, which can meet the needs of customers and improve equipment reliability.

Product definition

Operating specification
O Energy storage operation Confirm the inspection of the product for transport deformation, fix the mechanism to the switch and insert it into the lower right part of the mechanism with a dedicated operating handle. Rotate clockwise (or charge the motor) till cracking sound occurs, which indicates the finish of energy storage. O Closing operation Press the green button, and the breaker switch is closed by the spring force of the mechanism. Or when the motor is operated, the closing operation of the closing coil charging mechanism is completed, and the opening spring is stored. At this time, the energy can be stored again but cannot be closed again (with interlock). O Opening operation Press the red button, and the breaker switch is opened by the spring force of the mechanism. Or when the motor is operated, the opening operation of the opening coil charging mechanism is completed.
