본 고안은 부하와 제어장치의 전원을 별도 분리하여 부하에 전원이 인가되지 않을 때에는 제어 장치에도 전원이 인가되지 않도록 하여 필요없는 전력손실을 제거하기 위한 전력 제어장치에 관한 것이다.The present invention relates to a power control device for removing unnecessary power loss by separating power from the load and the control device so that power is not applied to the control device when power is not applied to the load.
종래에도 제3도에 도시된 바와 같이 AC입력(31)을 주부하(32)와 제어기(33) 에 병렬 접속하되 주부하(32)측에는 스위치(SW)를 달아서 주부하(32)측 전원을 제어 하도록 되어 있으나, 스위치(SW)를 오프하여 주부하(32)에 전력을 공급하지 않더라도 제어기(33)측에는 연속적으로 AC입력(31)이 인가되어 지속적인 전력낭비가 많았다.Conventionally, as shown in FIG. 3, the AC input 31 is connected in parallel to the main load 32 and the controller 33, and the main load 32 is connected to the main load 32 by supplying a switch SW. Although it is to control, even if the switch (SW) is off to supply power to the main load 32, the controller 33 side is continuously applied to the AC input 31, there was a lot of continuous power consumption.
본 고안은 이러한 종래의 단점을 제거하도록 주부하측의 AC전원선에 전류감지기를 설치하여 주부하측에 AC전원이 공급될 때에만 제어기측에 작동전원이 공급토록하여 필요없는 지속적인 전력낭비를 없이할 수 있는 전력제어장치를 제공하는 것을 목적으로 하며, 이하 첨부된 도면을 참조하면서, 본 고안의 구성, 작용 효과를 설명하면 다음과 같다.The present invention installs a current sensor on the AC power line of the main load side to eliminate this conventional disadvantage, so that the operating power is supplied to the controller side only when AC power is supplied to the main load side, eliminating unnecessary unnecessary power waste. An object of the present invention is to provide a power control device, which will be described below with reference to the accompanying drawings.
제1도 및 제2도를 참조하면 본 고안장치는 주부하측(1)측 AC전원선의 일측선에 변류기(2)를 설치하고, 변류기(2)의 출력을 다이오드(D)와 평활콘덴서(C1) 및 로직트라이악(LT)으로 구성된 정류단(3)에서 정류하고 제어기(4)의 AC전원선에 직렬로 연결된 트라이악(TAiC)의 게이트에 정류단(3)의 출력을 연결하여 된 구성으로서 이러한구성의 작용효과를 설명하자면 먼저 스위치(SW)를 오프한 상태에서는 주부하(1)측 AC전원선에 전류가 흐르지 않으므로 변류기(2)에 전압이 유기되지 않아 정류단(3)에서의 출력이 없다.Referring to FIGS. 1 and 2, the device of the present invention includes a current transformer 2 installed at one side of an AC power line of the main load side 1, and the output of the current transformer 2 is a diode D and a smoothing capacitor C. 1 ) and rectifying at the rectifying stage 3 composed of logic triac LT and connecting the output of the rectifying stage 3 to the gate of the triac TAiC connected in series with the AC power line of the controller 4 In order to explain the effect of such a configuration, first, when the switch SW is turned off, no current flows in the AC power line of the main load 1 side, so that no voltage is induced in the current transformer 2, There is no output.
만약 스위치(SW)를 온 상태로 하면, 주부하(1)에 AC전원이 공급되므로 AC전원선에 전류가 흐르기 시작하여 변류기(2)에 2차전압이 유기된다. 변류기(2)에 유기된 2차전압은 정류단(3)에서 다이오드(D)로 정유된 다음 평활콘덴서(C1)에 의하여 평활된 후 로직트라이악(LT)을 도통시킨다. 이에 따라서, 제어기(4)의 AC전원선에 직렬로 연결된 트라이악(TAiC)의 게이트에 논리트라이악(LT)로 통과한 다이오드(D)에서의 정류전압이 인가되어 트라이악(TAiC)이 도통되고, 이에 따라 제어기(4)의 AC전원이 인가된다.If the switch SW is turned on, since AC power is supplied to the main load 1, current begins to flow in the AC power line and secondary voltage is induced in the current transformer 2. The secondary voltage induced in the current transformer 2 is rectified by the diode D in the rectifier stage 3 and then smoothed by the smoothing capacitor C 1 to conduct the logic triac LT. Accordingly, the rectified voltage from the diode D passed through the logic triac LT is applied to the gate of the triac TAiC connected in series with the AC power line of the controller 4 so that the triac TAiC conducts. Thus, AC power of the controller 4 is applied.
이상에서 설명된 바와 같이 본 고안에 의하면 주부하의 전원스위치(SW)를 온ㆍ오프하므로서 이에 따라 자동적으로 제어기(4)의 전원이 온ㆍ오프되므로 주부하에 AC전원이 인가되지 않으면 제어기에도 AC전원이 인가되지 않아 필요없는 전력손실이 없는 것이다.As described above, according to the present invention, the power switch SW of the main load is turned on and off, and accordingly, the power of the controller 4 is automatically turned on and off. Therefore, if the AC power is not applied to the main load, the AC power is also supplied to the controller. There is no unnecessary power loss because it is not authorized.
