Abstract
PURPOSE: To adapt a breaker in the end of a variable electric source for a previous closing by hand by locking the output of a phase comparison relay on conditions of "open" of the breaker of the self-end, "off" of line voltage, and the issue of a closing instruction of the breaker.
CONSTITUTION: Outputs of a breaker manual closing instruction circuit 201, a breaker "open" detecting circuit 202, and a line-voltage "off" detecting circuit 203 are input into an AND circuit 206 to be supplied to a flip-flop circuit 204 together with outputs of NOT circuits 209 and 210 and a line-voltage "on" confirming on- delay timer 211. then, the output of a phase comparison relay 205 is locked by continuous F1 control or the rising of current level to be maintained until the completion of the closing of the breaker is confirmed for a fixed time. In this construction, when a breaker is closed earlier in the end of a variable electric source for starting operation on the basis of restrictions of the system operation, a previous closing can be ensured.
