Abstract: 220kV line protection agencies for me to operate closed-loop problem of the aging, operation of microprocessor-based protection combined with me now more reliable performance. Now take full advantage of the reliability of microprocessor-based protection devices can, circuit breaker will be closed to protect from the original single-loop combination locking relay, Now replaced by the use of closed-loop operation box, To improve the reliability of the circuit, Ensure the normal operation of microprocessor-based protection。
