Claims (1)

와이어 전극과 공작물 사이에 전압을 인가하여 방전가공을 행하는 와이어 절단 방전 가공 전원에 대하여 전원 전압이 소정값 이상으로 상승하는 것을 검출하기 위한 전원 전압 및 기준 전압을 비교하는 비교기와 저항을 통해 전원에 병열로 접손되 있고 비교기의 검출 출력에 의해 도통 제어되는 스위칭소자를 구비하고 있는 것을 특징으로 하는 와이어 절단 방전 가공 전원.Parallel to the power supply through a comparator and a resistance comparing the power supply voltage and the reference voltage for detecting that the power supply voltage rises above a predetermined value with respect to the wire cutting discharge machining power supply for applying electrical discharge between the wire electrode and the workpiece. And a switching element which is folded into and is electrically controlled by the detection output of the comparator. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
