| 摘要 | PURPOSE: To control a relay by opening or closing a zero-current point in an AC load circuit with a relay connected to a load, and controlling an operating or dropout point so as to eliminate arc discharge in a relay contact. CONSTITUTION: A relay 42 and a detector 46 are connected to an AC circuit and a control circuit respectively, in order to minimize relay arc discharge by operating a relay 42 so as to open or close the contact in a zero-current point in the AC circuit. That is, the control circuit receives an instruction signal, inspects its memory, sends an operation signal to the relay to operate the relay 42 by opening or closing the contact in the zero-current point. When a load is switched to on or off, the relay for supplying an AC load is controlled, so as to minimize arc discharge in the relay contact and maximize the life time of the relay.
