Abstract

본 발명은 릴레이(relay)를 온·오프시킬때 발생되는 릴레이 스위치접점의 전위현상으로 기인된 스위치의 손상을 방지하여 제품의 수명을 연장하도록 한 릴레이의 스위치접점 전위현상 방지제어방법에 관한 것으로, 부하(20)에 인가되는 전원(13)에 따른 전원주파수와 동기하여 상기 부하(20) 구동용 릴레이(15)를 제어하는 방법에 있어서, 상기 전원주파수에 동기하여 릴레이(15) 온출력을 행할때에는 전원의 정전압이 인가되는 시기에, 상기 릴레이(15) 오프출력을 행할때에는 전원의 부전압이 인가되는 시기에, 또는 그 반대로 하여 상기 릴레이(15) 온·오프시에 전원의 정 또는 부전압이 번갈아가며 인가되도록 한 것을 특징으로 하는 릴레이의 스위치접점 전위현상 방지 제어방법.The present invention relates to a control method for preventing switch contact potential phenomenon of a relay to prevent damage to a switch caused by a potential phenomenon of a relay switch contact generated when a relay is turned on and off, thereby extending the life of the product. In the method for controlling the relay 20 for driving the load 20 in synchronization with a power source frequency according to the power source 13 applied to the load 20, the relay 15 may be turned on and output in synchronization with the power source frequency. When the constant voltage of the power supply is applied, when the output of the relay 15 is performed, when the negative voltage of the power supply is applied, or vice versa, the positive or negative voltage of the power supply when the relay 15 is turned on and off The switch contact potential prevention control method of the relay, characterized in that the alternating application.
