<p>PURPOSE: To eliminate disconnecting to the power source side and the load side of a breaker by operating a lever coupled to the breaker, longitudinally moving a support and separating or bringing the two movable contactors of the breaker from or into contact with both contactors. CONSTITUTION: When a breaker 40 is disconnected by operating means 58, an operating lever 59 is moved down, a shaft 48 is rotated counterclockwise via a lever 60, a coupling lever 50 is moved to the rear via a lever 49, a main shaft 51 is rotated counterclockwise via a lever 52, and the breaking unit of the breaker 40 is tripped. The motor of drive means is reversely rotated in this state, a support 43 is moved forward, the breaker 40 is moved forward together with a support lever 46, and both movable contactors 41, 42 are separated from both stationary contactors 33, 34 in a disconnected state. On the other hand, when the breaker 40 is connected, the motor of the drive means is rotated forward, the breaker 40 is moved to the rear, both contactors 41, 42 are connected to both contactors 33, 34 to the connected state. Thus, a disconnecting to the power source side and the load side of the breaker 40 is eliminated.</p> |
