Description
제1도는 본 고안의 회로도.1 is a circuit diagram of the present invention.
본 고안은 보조전압을 이용한 절전형 교류아크 용접기에 관한 것으로, 더 자세히는 변압기의 1차측에 110V와 220V전원이 인가되도록 된 2차측 양단이 보조권선을 병설하여 이들간에는 트라이악과 콘덴서가 직열로 연결하고 출력측의 일단에 감지용 쵸크코일이 유도되어 트라이악의 캐소드와 게이트에 연결하여서 된 것으로 용접작업 개시, 즉 부하가 걸리면 동시에 쵸크코일에 유도된 전력에 의하여 트라이악을 도통되어 양 보조권선에 유기된 전압이 출력단에 가합 인가되므로서 높은 전압으로 아크 발생을 용이하게 하므로서 2차 주권선측에 유도된 전압, 측 무부하전압을 아크를 유지할 수 있는 저전압으로 하므로서 용접기의 역률을 90%이상 개선하도록 함을 목적으로 하는 것이다.The present invention relates to a power-saving AC arc welder using an auxiliary voltage. More specifically, secondary ends of the secondary side to which 110V and 220V powers are applied to the primary side of a transformer are provided with auxiliary windings, and a triac and a capacitor are connected in series. The sensing choke coil is induced at one end of the output and connected to the triac cathode and gate.The welding operation starts, that is, when the load is applied, the triac is conducted by the electric power induced in the choke coil and induced to both auxiliary windings. It is applied to this output terminal to facilitate the generation of arc at high voltage, and to improve the power factor of the welder by 90% by making the voltage induced on the secondary main winding side and the no-load voltage side low to maintain the arc. It is.
본 고안 출원인은 절전형 교류아크 용접기에 관한 여러가지 발명 고안을 출원하고 실제 제품을 제조 시판하므로서 절전형 교류아크 용접기가 대호평을 받고 있으며, 본 고안은 이와 같은 선 발명 고안들의 연관된 개량 고안으로 첨부도면에 의하여 상세히 설명하면 다음과 같다.Applicant of the present invention has filed various invention designs related to the power-saving ac arc welder and manufactures and marketed the actual product, and the power-saving ac arc welder has been very popular. It will be described in detail as follows.
교류아크 용접기의 메인트랜스 MT의 1차측에는 110V와 220V의 전원이 인가되도록 되고 2차측에는 주권선 N3및 N4의 외측에 보조권선 N5,N6를 각기 병설 연결하고 이들 보조권선 간에는 트라이악 TRAC과 콘덴서 C가 직열로 연결되고 출력측 OUT PUT의 일단에는 감지용 쵸크코일 L이 유도되어 크라이악 TRAC의 캐소드와 게이트 G에 연결하여서 된 것이다.110V and 220V power is applied to the primary side of the main transformer MT of the AC arc welder, and the secondary windings N 5 and N 6 are connected to the secondary side of the main windings N 3 and N 4 , respectively. The evil TRAC and capacitor C are connected in series and the sensing choke coil L is induced at one end of the output PUT and connected to the cathode and gate G of the Cryak TRAC.
이와 같이된 본 고안은 무부하시에는 보조코일 N5,N6의 전압은 트라이악 TRAC이 도통되지 않어 출력단 OUT PUT에는 주권선 N3및 N4의 전압이 나타나지만 용접작용으로 출력단에 부하가 걸리면 쵸크코일 L에 유기된 전압이 트라이악 TRAC의 게이트 G를 도통하여 콘덴서 C를 통해 출력단 OUT PUT에 인가되어 출력단 OUT PUT에는 무부하전압 E0와 보조전압 E1,E2의 합계 E0+E1+E2의 높은 전압으로 되어 아크발생을 용이하게 하는 것이다.In this design, the voltage of the auxiliary coils N 5 and N 6 at no load does not conduct the triac TRAC, so the voltage at the main windings N 3 and N 4 appears at the output OUT PUT. The voltage induced in the coil L conducts to the gate G of the triac TRAC and is applied to the output terminal OUT PUT through the capacitor C. The output terminal OUT PUT has the sum of no-load voltage E 0 and auxiliary voltages E 1 and E 2 E 0 + E 1 + The high voltage of E 2 facilitates arcing.
따라서 주권선 N5및 N4에 유기되는 전압(무부하전압 E0)을 아크유지에 충분할 정도의 낮은 전압으로 할수 있으므로 역률이 대폭 개선되는 것으로 실제 제품실험에서는 역률이 90-95%이었고 종래 일반 교류아크 용접기의 역률45%정도에 비하면 전력소비가 1/2정도로 절전되는 것으로 역률 개선으로 이루어지는 전력은 전주적으로 본다면 큰 발전소 하나 정도에서 발전하는 적력에 해당되어 국가적 에너지 절약에 기여하는 바 큰 것이다.Therefore, the power factor is greatly improved because the voltage induced at the main windings N 5 and N 4 (no-load voltage E 0 ) can be made low enough to maintain the arc. The power factor is 90-95% in the actual product test. Compared with 45% of the power factor of arc welding machine, the power consumption is reduced by about 1/2. Power generated by power factor improvement is the major force generated by one large power station, which contributes to the national energy saving.
