Sf6 Circuit Breaker Operating Mechanism Three-phase Split Circuit Breaker Closing Circuit

Analysis of the action process of GL314sf6 circuit breaker operating mechanism:
Action process of closing coil Y01: When the switch is in the open position, when sf6 circuit breaker spring mechanism receives the closing command issued by DCS or the local button, the power supply is returned to the negative pole of the power supply from the positive pole through the command contact, through the anti-trip lock K01 closing contact, the circuit breaker position lock auxiliary contact (S01, S04) - closing coil Y01 - gas lock closing contact (K13 and K03).
Action conditions of closing coil Y01: When the closing coil Y01 is energized and the circuit breaker is closed, no matter whether the closing command disappears or not, the closing command is only issued once through the anti-trip relay K01 lock; secondly, if the circuit breaker closing command disappears, the circuit breaker cannot issue a closing command in the closed position due to the lock of the auxiliary contacts (S01, S04); the circuit breaker is allowed to open only when the gas relay does not issue a lock command (K03, K13 do not act).
