리레이 작동케된 절전콘덴서를 가지는 교류아크 용접기AC arc welding machine with relay operated power saving capacitor

제1도는 본 고안의 회로도.1 is a circuit diagram of the present invention.

본 고안은 리레이에 의하여 작동케된 절전용 콘덴서를 용접기 1차측에 연결하여서된 것이다.The present invention is made by connecting the power saving capacitor operated by the relay to the primary side of the welding machine.

종래 교류아크 용접기에는 역률 개선을 목적으로 별도의 진상용 콘덴서를 사용할 필요가 있었고 또 본원 출원인은 특허원82-3463 및 실용신안원 82-6392, 82-6330호 등의 발명 고안에 따른 아크유도 회로에 의한 고전압을 용접기2차측에 인가하도록 함으로서 무부하전압을 낮게 하여 역률을 90%이상 향상시켜 전력을 절약하도록 한 절전용 교류아크 용접기를 개발하는 과정에서 용접기 1차측 전원에 진상용 콘덴서를 연결하여 왔던 것이다.In the conventional AC arc welding machine, it is necessary to use a separate fastening capacitor for the purpose of improving the power factor, and the applicant of the present application is an arc induction circuit according to the invention design of Patent Application 82-3463 and Utility Model Application 82-6392, 82-6330. In the process of developing a low-voltage AC arc welder that saves power by lowering the no-load voltage to improve the power factor by more than 90% by applying a high voltage to the secondary side of the welder, the condenser for the forward side of the welder was connected to the primary power source of the welder. will be.

그런데 종래의 이러한 목적의 콘덴서는 용접기 2차측의 전압이 높아진 경우나 또는 2차측에 부하가 걸려 전압이 낮아진 경우를 불문하고 일정의 큰 용량의 콘덴서가 연결되어 있어 무부하시에 전력소비를 증대시키는 결과가 되었던 것이다.However, the conventional condenser for this purpose is a result of increasing the power consumption at no load because the capacitor of a large capacity is connected regardless of whether the voltage on the secondary side of the welder is high or the load is reduced on the secondary side. It became.

본 고안은 이러한 종래의 결함을 시정하고저 용접기 1차측에 무부하전압에 상응한 콘덴서와 병열로 부하로 인하여 2차측에 많은 전류와 전압이 낮아진 경우에 리레이에 의하여 접속되는 절전용 콘덴서를 연결하므로서 부하시 병용되도록 하여 무부하시의 전력을 절약할 수 있도록 한 것이다.The present invention corrects such a conventional defect and connects a power saving capacitor connected by a relay when a large amount of current and voltage are lowered on the secondary side due to a load by a capacitor and a parallel load on the primary side of the low welding machine. It is designed to be used at the time of load to save power at no load.

이하 본 고안은 첨부회로도에 의하여 상세히 설명한다.Hereinafter, the present invention will be described in detail by the accompanying circuit diagram.

1차측 전원에 진상용 콘덴서 C4를 연결한 교류아크 용접기에 있어서 상기 콘덴서 C4와 병열로 리레이 RE1에 의하여 접속 작동하는 절전용 콘덴서 C5를 연결하였으며, 주변압기 MT의 2차측에 가변저항(R9)과 고정저항(R10)및 콘덴서(C3)로 되는 분압회로가 구성되어 분압된 전류는 제너다이오드(ZD3)와 저항R4, R5을 통해 에미터 접지된 트랜지스터(Q2)의 베이스에 연결되고 콜렉터는 제너다이오드(ZD2)를 통해 에미터 접지된 트랜지스터 Q1의 베이스에 연결되어 있다.In the primary side the fast AC arc welder is connected to the capacitor C 4 for the power source was connected to the section dedicated capacitor C 5 to work up by a relay RE 1 in the capacitor C 4 and byeongyeol, variable on the secondary side of the main transformer MT A divider circuit consisting of a resistor (R 9 ), a fixed resistor (R 10 ), and a capacitor (C 3 ) is configured so that the divided current is emitter grounded through a zener diode (ZD 3 ) and resistors R 4 , R 5 ( Is connected to the base of Q 2 ) and the collector is connected to the base of an emitter grounded transistor Q 1 through a zener diode (ZD 2 ).

또 신호용 변압기T1와 브리지 정류회로 BD1로 구성된 정류전압은 저항 R1과 리레이 RE1가 직열연결 되어 상기한 트랜지스터(Q1)의 콜렉터에 연결하여서 된 것이다. 도면중 미설명 부호 C1-C2은 평활용 콘덴서이며 R2,R3은 저항 ZD1의 제너다이오드 D2는 다이오드를 의미한다.In addition, the rectified voltage composed of the signal transformer T 1 and the bridge rectifier circuit BD 1 is obtained by connecting the resistor R 1 and the relay RE 1 in series with the collector of the transistor Q 1 . In the drawings, reference numerals C 1 -C 2 denote smoothing capacitors, and R 2 and R 3 denote zener diodes D 2 of the resistor ZD 1 .

상기와 같은 구성으로 된 것이므로 주변압기 MT의 일차측에 전원을 인가하면 2차측에 유기되는 전압은 다이오드D2에 의해 반파정류되고, 저항(R10)가 가변저항R9에 의해 분압된 전압은 제너다이오드 ZD3의 설정된 한정치를 넘게 되면 에미터 접지된 트랜지스터(Q2)의 베이스를 트리거 하여 도통됨으로서 브리지 정류회로(BD1)의 정류된 전류는 저항(R2)을 통해 흐르게 된다.Since the above configuration is applied, when the power is applied to the primary side of the peripheral voltage MT, the voltage induced on the secondary side is half-wave rectified by the diode D 2 , and the voltage at which the resistor R 10 is divided by the variable resistor R 9 is When the set limit value of the zener diode ZD 3 is exceeded, the base of the emitter grounded transistor Q 2 is triggered so that the rectified current of the bridge rectifying circuit BD 1 flows through the resistor R 2 .

이와같은 상태에서 용접부를 응접키 위하여 접지되면 많은 전류가 용접부로 흐르게 되므로 분압회로에 흐르는 전류가 감소함에 따라 설정된 규정치 이하의 전류로 제너다이오드(ZD3)는 불통되므로 지금까지 도통상태에 있던 트랜지스터(Q2)가 OFF됨으로서 저항(R2)에 의해 접지측으로 흐르고 있던 전류는 제너다이오드(ZD2)를 도통시켜 에미터 접지된 트랜지스터(Q1)를 도통시켜 주무로 리레이 RE1가 여자되어 주변압기(MT)의 1차측에는 콘덴서(C5)와 직열 연결된 릴레이 접점(RE1)이 ON된다.In this state, when grounded to weld the welded part, much current flows to the welded part. As the current flowing in the voltage dividing circuit decreases, the zener diode ZD 3 is turned off by the current below the set value, so that the transistor (which has been in the conducting state until now) When Q 2 ) is turned off, the current flowing to the ground side by the resistor R 2 conducts the zener diode ZD 2 to conduct the emitter grounded transistor Q 1 , causing the relay RE 1 to be excited. On the primary side of the transformer MT, the relay contact RE 1 connected in series with the capacitor C 5 is turned on.

따라서 진상용 콘덴서(C4)와 콘덴서(C5)가 병열상태가 되어 주변압기(MT)외 1차측에는 용량이 증가된 콘덴서를 2차측에 유기되는 용접전류를 증가시켜 주고 용접이 끝나면 다시 분압회로의 규정치를 넘는 전압변화에 따라 다시 제너다이오드(ZD3)가 도통되어 에미터 접지된 트랜지스터 Q2를 도통시킴으로서 브리지 정류회로 BD1의 정류된 전류가 트랜지스터(Q2)에 의해 접지로 흐르므로 제너다이오드 ZD2에는 전류가 도통되지 않아 에미터 접지된 트랜지스터 Q1를 OFF시켜 리레이(RE1)의 리레이 접점(RE1)도 OFF되어 주변압기(MT)의 1차측에 연결된 콘덴서(C5)용량이 제거되어 전하전력을 절약할 수가 있게 되는 것이다.Therefore, the condensing capacitor (C 4 ) and the condenser (C 5 ) become parallel, increasing the welding current induced in the secondary side of the capacitor with increased capacity on the primary side and the surrounding pressure (MT). As the zener diode ZD 3 conducts again and conducts the emitter grounded transistor Q 2 according to the voltage change exceeding the specified value of the circuit, the rectified current of the bridge rectifier circuit BD 1 flows to the ground by the transistor Q 2 . Zener diode ZD 2 is to turn OFF the emitter grounded transistor Q 1 because current is not conducting relay (rE 1) of the relay contacts (rE 1) FIG capacitor connected to the primary side of the OFF main transformer (MT) (C 5 ) Capacitance can be removed to save charge power.
