| 摘要 |
The present invention relates to an energy storing apparatus of a vacuum circuit breaker, in particular to an energy storing apparatus of such a vacuum circuit breaker for absorbing impact between an energy storing gear and a braking pawl caused by reverse rotation of the energy storing gear generated during a closing operation, thereby preventing the damage and wear of the built-up members. The energy storing apparatus can comprise an energy storing gear configured to be rotated through receiving electric power from a motor; a lever configured to transmit the rotation force of the energy storing gear; and a closing spring tensioned by the lever and provided with a hook and a brake therein, and the reset displacement of the closing spring is limited by the contact between the hook and the brake. |
