Abstract

PURPOSE:To prevent circuit disconnection for a long period of time by driving a timer circuit with an alarm signal given from a voltage monitor circuit, at the same time counting the short-circuit frequencies and inhibiting the short-circuit when the count value of short-circuits reaches a prescribed level. CONSTITUTION:When a circuit breaker 2 is turned off by the surge voltage, etc., a voltage monitor circuit 9 detects a drop of the output voltage 102 given from a stabilized power supply circuit 3. An alarm signal 103 is applied to a drive circuit 10 of a relay 8 from the circuit 9, and therefore a contact 81 of the relay 8 is turned on. Then an earth signal 105 is sent to a timer circuit 7. This circuit 7 drives a relay 5 when the time T1 has passed and turns on a relay contact 51 set in parallel to the breaker 2. At the same time, the time counting is also started. Thus the circuit 9 detects the normal voltage, and the contact 51 is kept closed even after the signal 103 is delivered during the OFF time T2 of the relay 8. For this purpose, the relay 5 is controlled. Furthermore, the normal voltage is also supplied to a counter circuit 6 to count the short-circuit frequencies. When the count value of the counter 6 reaches a prescribed level, the drive of the relay 5 is stopped.
