본 고안은 출원인의 선발명 82-3463호, 특허1758호 및 동일자 실용신안출원인 교류아크 용접기의 아크유도 장치에서의 유도되는 아크유도 전압의 순화, 즉 진동 전압을 유기하도록 하므로서 상기 선발명 고안에서의 아크유도 전압이 단발식으로 유기되어 무부하 전압의 주파의 아크발생 위상에서 동시적으로 인가되록 함은 가장 바람직한 것이나, 실제 아크유도 회로의 각 소자의 특성에 의하여 아크유도 전압의 유기되는 위상이 다소 지연되거나 또는 빨라질수 있어 아크 발생에 무리를 야기하게 된는 문제점이 있는 것이다.The present invention proposes to purify the induced arc induction voltage in the arc induction apparatus of the AC arc welding machine, which is the applicant's prior application Nos. 82-3463, 1758, and the same utility model, that is, induces vibration voltage. It is most desirable that the arc induction voltage is induced in a single fashion and applied simultaneously in the arc generation phase of the frequency of no-load voltage, but the phase of the induction of the arc induction voltage is somewhat delayed by the characteristics of each element of the arc induction circuit. Or it may be faster to cause a problem in the generation of arc is a problem.
본 고안은 이러한 출원인의 선출원 발명 고안의 문제점을 감안하여 아크유도 회로에 의한 교류용접기에 있어서 아크 유도를 순탄하게 하기 위한 것으로 첨부 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is made in order to smooth the arc induction in the AC welding machine by the arc induction circuit in consideration of the problems of the applicant's prior application invention described in detail as follows.
제1도는 교류용접기MT와 병열로 본 고안 아크유도장치 I를 결선한 개략 회로도이며, 제2도는 본 고안의 상세한 회로도이다.FIG. 1 is a schematic circuit diagram of the arc induction device I of the present invention in parallel with the AC welding machine MT, and FIG. 2 is a detailed circuit diagram of the present invention.
제2도에서 SCR게이트 신호용 트랜스T1에 의해 SCR1, SCR2의 게이트에 가해지는 신호 전압은 항상 교대로 점호하도록 구성되어 있어, 예로서 다이오드CR1에 의하여 충전된 직류 전압을 SCR1가 콘텐서C1의 충전 전압을 코일 N1에 방전하고 있는 동안 콘텐서C2를 반대로 다이오드CR2에 의하여 충전되고 있는 상태이며, SCR2도 역시 캐소드쪽에 걸려있는 역전압에 의해 OFF상태로 되는바 SCR1과 SCR2는 콘텐서C1과 C2의 전압을 게이트 신호용 트랜스T1에서 지시하는 신호에 따라 교대로 ON, OFF되고 따라서 유도회로의 코일 N1과 N2는 교대로 유도되는 유도 전압 E1이 교류아크용접기의 2차 출력단에 인가되는 것은 선출원 발명에 설명한 바와 같다.In FIG. 2 , the signal voltage applied to the gates of SCR 1 and SCR 2 by the transformer T 1 for the SCR gate signal is configured to always alternately alternate. For example, the DC voltage charged by the diode CR 1 is converted into an SCR 1 cone. While discharging the charging voltage of the tensor C 1 to the coil N 1 , the capacitor C 2 is being charged by the diode CR 2 , and the SCR 2 is also turned off by the reverse voltage applied to the cathode. 1 and SCR 2 alternately turn on and off the voltages of capacitors C 1 and C 2 according to the signal indicated by the gate signal transformer T 1 , so that the coils N 1 and N 2 of the induction circuit alternately induce the induced voltage E 1 is applied to the secondary output of the AC arc welder as described in the prior application.
본원은 상기 선출원 발명 (82-3463, 특허17584호)의 아크류도 회로의 코일 N1과 N2에 각기 콘텐서C3,C4를 연결하여서된 것이다.The present application is made by connecting the capacitors C 3 and C 4 to the coils N 1 and N 2 of the arc flow diagram circuit of the above-described invention (82-3463, Patent 17584), respectively.
이와 같은된 본 고안은 콘텐서C1,C2의 충전전압을 SCR1,SCR2가 코일N1,N2에 방전하여 직류전압은 서로 교대로 점호하여 2차측 코일에 교류전압 E1을 유기하여 교류아크용접기의 2차 출력단의 두부하 전압 E」에 인가하여 높은 유도전압 E1은 P1으로 되었다.In the present invention, the charging voltages of the capacitors C 1 and C 2 are discharged to the coils N 1 and N 2 by the SCR 1 and SCR 2 , and the DC voltages are alternately fired to induce the AC voltage E 1 to the secondary coil. The high induced voltage E 1 became P 1 by applying it to the head load voltage E ”of the secondary output terminal of the AC arc welder.
콘텐서C1의 방전이 끝나기까지 점차 하강곡선을 그리나 이때 콘텐서C3의 충정전압은 저항R3로 인하여 시차를 가지고(지연되어)방전되므로 전기하강곡선은 콘텐서C3에 한 유도전압의 인가로 유도전압 E1은 다시 상승하게 되고 따라서 결국 합성유도전압E1은 제3도에서 보는 바와 같이 전압의 곡선이 굴곡된 진동파로 되므로 정확히 유도전압 E1의 피크점 P1이 무부하 전압E」의 피크점 P」와 위상을 약간 달리 하더라도 유도전압 E1의 진동파에 의하여 아크발생을 넓은 범위에서 얻을 수 있는 것이다.Loyalty voltage But, install isolated a gradually falling curve to the end of the discharge of the cone tensor C 1 The cone tensor C 3 is (delayed) with the time difference due to the resistance R 3 discharge because electric falling curve of the induced voltage in the cone tensor C 3 induced by an applied voltage E 1 is again raised thus eventually synthesizing the induced voltage E 1 is the exactly the induced voltage since the curve of the voltage of the flexural vibration wave E 1 as shown in FIG. 3 the peak point P 1 is the no-load voltage E " even if the slightly different peak point P 'and the phase is to obtain the arc generated by the oscillation wave of the induced voltage E 1 in a wide range.
따라서 본 고안은 아크발생을 순탄히 하여 용접기에 무리를 야기하지 아니하는 것이다.Therefore, the present invention is to smooth the arc generation does not cause an excessive welder.
