Closing delay arrangement for current limiting circuit breaker contacts. |
摘要 |
<p>A control arrangement to prevent or delay the closing of current limiting circuit breaker contacts after opening by repulsion due to a short circuit is disclosed. A first contact arm (10) and a second contact arm (12) are operatively associated with a ratchet (38) for locking the second contact arm (12). A release lever (62) operatable by the first contact arm (10) and the breaker operating mechanism releases the ratchet (38) after a delay period greater than the duration of the short circuit or the operating time of the breaker operating mechanism.</p> |
