| Abstract: |
| The design concept of breaker on-off hold circuit in current breaker operation e-quipment and its merits are reviewed,while the problems happened in operations and their possible consequences are analyzed. It is proposed to insert overtime relays in hold circuit to improve the operation reliability of circuit breaker and its auxiliary facilities. |
| Key words: hold circuit,overtime relay,improvement |
