첨부 도면은 본 고안의 회로도.The accompanying drawings are circuit diagrams of the present invention.

본 고안은 부피가 작고 중량이 가벼워 이동 및 보관이 편리하며 작업시에 소음이 없고 제어특성이 우수할뿐만 아니라 직류이므로 감전에 위험이 없으며 무부하 손실이 거의 없고 소전력에서 대전력이 필요한 용접작업시에 방전 안정도가 우수하도록한 광 제어식 삼상직류 용접기에 관한 것이다.This design is small in size and light in weight, so it is easy to move and store, and there is no noise during operation, excellent control characteristics as well as direct current, so there is no risk of electric shock, almost no load loss, and welding work requiring high power at low power. The present invention relates to a light-controlled three-phase DC welding machine having excellent discharge stability.

종래에 사용되었던 교류(AC) 용접기는 그 대개가 부피가 크고 중량이 무거웠으며 소전력을 사용하는 용접작업시에 대전력을 필요로 하는 광범위의 용접작업에는 사용이 거의 불가능하였을 뿐만 아니라 많은 전력이 소비되어 비 경제적이고 많은 소음이 발생되어 소음 공해를 일으키는 요인이 되었었다.AC welding machines used in the past were usually bulky and heavy, and were almost impossible to use for a wide range of welding operations requiring a large amount of electric power. It was consumed, was uneconomical and produced a lot of noise, causing noise pollution.

본 고안은 상술한 종래의 제결점을 해소하기 위하여 광량에 따라 저항변화를 일으키는 광도전실을 사용하여 전류를 제어하고 제어된 주 전력을 이용하기전에 초기방전을 일으키도록 하므로서 용접작업시 소전력을 필요로 하는 용접에서부터 대 전력을 필요로 하는 광범위의 용접작업을 손쉽게 행할수 있을 뿐만 아니라 전체의 구성을 전자식으로 하였기 때문에 그 부피가 작고 중량이 가벼워 이동 및 보관이 편리하며 작업시에 소음이 없어 소음 공해를 미연에 방지할수 있도록 한 것으로 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention uses a photoconductor chamber that causes a resistance change according to the amount of light in order to solve the above-mentioned conventional defects, so that electric power is required during welding operation by controlling the current and causing initial discharge before using the controlled main power. It is not only easy to carry out a wide range of welding work that requires high power from welding, but also the whole structure is made electronically, so its volume is small and light, so it is convenient to move and store, and there is no noise in the work. It will be described in detail with reference to the accompanying drawings so as to prevent in advance as follows.

1차, 2차, 3차(N1,N2,N3)권선으로 구성된 트랜스(To)와 초기방전을 위하여 2차권선(N2)에 각각 코일(L1,L2,L3)을 거쳐 직렬 연결된 SCR(a,b,c)과 SCR(a,b,c)의 에노드와 게이드 사이에 병열 연결된 저항(R1,R2,R3) 및 다이오드(D1,D2,D3)와 각각의 스위치(SW1,SW2,SW3)로 구성되며 축전지(C)의 일측단자에 ON, OFF 스위치를 설치하고 가변저항(VR)에 의하여 램프(PL)광량을 조절하며 램프(PL)의 광량이 광도전셀(cds1,cds2,cds3)의 저항변화를 일으켜 SCR(A,B,C)에 게이팅 신호를 가하고 또한 게이팅신호에 의해 구동된 SCR(A,B,C)은 주전력 공급을 제어하는 SCR(Pa,Pb,Pc)을 구동시켜 SCR(Pa,Pb,Pc)에 전류, 전압을 제어하도록 한 것이다.Coils (L 1 , L 2 , L 3 ) in transformers (To) consisting of primary, secondary, and tertiary (N 1 , N 2 , N 3 ) windings and secondary windings (N 2 ), respectively, for initial discharge. Resistor (R 1 , R 2 , R 3 ) and diode (D 1 , D 2 , connected in parallel between the SCR (a, b, c) and the anode and the gate of SCR (a, b, c) connected in series D 3 ) and each switch (SW 1 , SW 2 , SW 3 ) and install ON / OFF switch at one terminal of the battery C and adjust the lamp light quantity by variable resistance VR. The amount of light of the lamp PL causes the resistance change of the photoconductive cells cds 1 , cds 2 , cds 3 to apply a gating signal to the SCRs A, B, and C and is driven by a gating signal. (C) is to drive the SCR (Pa, Pb, Pc) for controlling the main power supply to control the current and voltage to the SCR (Pa, Pb, Pc).

이와 같이된 본 고안의 작용효과를 설명하면 삼상교류를 각각 트랜스(To)의 입력선(R.S.T.)에 의해 1차권선(N1)에 연결되고 2차 권선(N2) 및 3차권선 (N3)에 각각 유기된 전압은 2차권선(N2)에서는 1차권선(N1)에 흐르는 전압의 1/4이고 3차 권선(N3)에서는 약 6V-8V이며 전류는 1A미만의 미약한 출력을 나타낸다.When explaining the effect of the present invention as described above three-phase alternating current is connected to the primary winding (N 1 ) by the input line (RST) of the transformer (To), respectively, the secondary winding (N 2 ) and the tertiary winding (N 3) each of the voltage induced is a secondary winding (N 2) and in one quarter of the voltage across the primary winding (N 1) three primary winding (N 3) the approximately 6V-8V to the current is less than 1A weak Indicates one output.

다이오드(SD1,SD2,SD3)의 캐소드를 2차 권선(N2)의 일측에 연결하여 (-)전류만 흐르도록 되어 있으며 또, 한다이오드(DS1,DS2,DS3)의 에노드는 용접기의 방전부분(W1)에 연결되어 있다. 코일(L1,L2,L3)을 거쳐 2차권선(N2)에 직렬 연결되어 있는 SCR(a,b,c)은 저항(R1,R2,R3) 및 다이오드(D1,D2,D3)와 스위치(SW1,SW2,SW3)에 의해 게이팅 되어 초기방전을 위하여 저항(RS)과 대용량 전해 콘덴서(CN) 및 코일(H)로 이루어진 평활회로를 거쳐 용접기 방전부분(W2)에 연결되어 진다.The cathodes of the diodes SD 1 , SD 2 and SD 3 are connected to one side of the secondary winding N 2 so that only the negative current flows and the diodes DS 1 , DS 2 and DS 3 The anode is connected to the discharge portion W 1 of the welder. The SCRs (a, b, c) connected in series to the secondary winding (N 2 ) via the coils (L 1 , L 2 , L 3 ) have a resistor (R 1 , R 2 , R 3 ) and a diode (D 1). , D 2 , D 3 ) and the switch (SW 1 , SW 2 , SW 3 ) are gated through a smoothing circuit consisting of resistor (RS), large capacity electrolytic capacitor (CN), and coil (H) for initial discharge. It is connected to the discharge portion (W 2 ).

여기서 소전력이 필요한 용접을 할때는 초기방전을 스위치(SW1)을 작동시켜 SCR(a)를 구동 시키고 접점 더 높은 전력이 필요한 용접을 할때는 스위치(SW2) 및 스위치(SW3)을 전부 작동시켜 용접에 필요한 전력만큼 초기 방전을 시켜주게 된다.In this case, when welding is required for low power, the initial discharge is operated by the switch (SW 1 ) to drive the SCR (a), and when the welding is required for higher power, the switch (SW 2 ) and the switch (SW 3 ) are all operated. Initial discharge as much as the power required for welding.

초기 방전으로 용접이 시작되면 ON-OFF 스위치를 동작시켜 측전지(C)에서 가변저항(VR)을 거쳐 필요한 전력량 만큼 제어할수 있도록 램프(PL)의 광량을 조정하여 암실로 되어 있는 Box에서 광도전셀(cds1,cds2,cds3)이 저항변화를 일으키면서 전류가 3차 권선(N3)에 연결되어 있는 저항(R5,R6,R7)을 거쳐 다이오드(D1,D2,D3)를 통하여 SCR(A,B,C)을 게이팅 시켜준다.When welding starts by the initial discharge, operate the ON-OFF switch to adjust the amount of power of the lamp (PL) to control the required amount of power through the variable resistor (VR) from the side battery (C). The cells (cds 1 , cds 2 , cds 3 ) cause a change in resistance and the diodes (D 1 , D 2 ) pass through the resistors R 5 , R 6 , and R 7 where the current is connected to the tertiary winding (N 3 ). , D 3 ) to gate the SCR (A, B, C).

SCR(A,B,C) 가구동 되면 이곳에서 1차 제어된 신호가 주 전력 공급을 제어하는 SCR(Pa,Pb,Pc)의 게이트에 저항(Ra,Rb,Rc)을 통하여 게이팅 신호를 제공하므로서 SCR(Pa,Pb,Pc)이 구동한다. SCR(Pa,Pb,Pc)이 구동 되면 제어된 전압, 전류가 저항(RS), 콘덴서(CN), 코일(H)로 구성된 평활회로를 거쳐 용접기 방전 부분(W2)에 인가 된다.When the SCR (A, B, C) is built, the primary controlled signal provides the gating signals through the resistors Ra, Rb, and Rc to the gates of the SCRs (Pa, Pb, and Pc) that control the main power supply. As a result, the SCRs (Pa, Pb, Pc) are driven. When the SCRs Pa, Pb, and Pc are driven, the controlled voltage and current are applied to the welder discharge portion W 2 through a smoothing circuit composed of a resistor RS, a capacitor CN, and a coil H.

축전지(C)는 저항(R4), 다이오드 (D7) 및 정전압다이오드(ZD)로 구성된 정전압회로를 거쳐 충전 되며 SCR(A,B,C)의 에노드는 3차권선(N3)의 일측단자에 연결되고 SCR(Pa,Pb,Pc)의 에노드는 2차권선(N2)의 일측단자에 연결 된다. 상술한 바와 같은 본 고안은 전자식으로 되어 있어 그 부피가 작고 중량이 가벼워 보관 및 이동이 편리하며 제어특성이 우수할 분만 아니라 용접 작업시에 전력손실을 적게하여 주면서 오음이 거의 없으며 소 전력에서 대 전력에 이르기 까지의 작업에 필요한 전력을 광범위하게 사용할수 있게 되므로 누구나 손쉽게 사용할 수 있는 이점이 있게 된다.The battery C is charged through a constant voltage circuit composed of a resistor R 4 , a diode D 7 and a constant voltage diode ZD, and the anodes of the SCRs A, B, and C are on one side of the tertiary winding N 3 . It is connected to the terminal and the anode of SCR (Pa, Pb, Pc) is connected to one terminal of the secondary winding (N 2 ). The present invention as described above is electronic, so its volume is small and light, so it is easy to store and move, and has excellent control characteristics, and there is almost no noise while reducing power loss during welding work. Since the power required for the operation to a wide range can be used, there is an advantage that anyone can easily use.
