Filed: 2000-10-31
Abstract: PROBLEM TO BE SOLVED: To count number of opening and closing times considering contact ablation due to applied current of the circuit breaker, and to alarm and indicate a service life of an opening/closing part when the count reaches a defined num ber. SOLUTION: Number M of opening and closing times until now is read out (41), the present contact output state (ON or OFF) is detected and the state is set as a previous value S1 (42), the present contact output state is detected at a predetermined interval and the state is set as a present value S2 (43). When the previous value is different from the present value (44) and it is contact OFF (break) (51), the number is corrected by a break current (52 and 53) and is counted (54). When the contact is not OFF but ON (51), the number is counted (45), and, when the counted number M reaches the defined number N (46), an alarm is outputted (47). When the number is smaller than the defined number, the present value S2 is set to the previous value S1 (48), and the operation is repeated from the step 43 until the counted number reaches the defined number.
