| Abstract: | Aiming at several problems existed in the typical designs of both the relay protection device of electrical equipment and the relevant secondary circuit, i.e. the reliability of starting-up the circuit breaker failure protection through the contact of permanent hop relay, the reliability of taking the auxiliary contact of isolating switch for stub protection of short-lead wire as the judging criterion of protection action, the closing circuit cannot be monitored under the normal operation condition of breaker, etc., some corresponding improvement measures are put forward herein. |
