본 고안은 전열기구 및 교류모터의 입력전류를 감지하여 과전류가 흐르지 않도록 하는 전력조절기에 관한 것이다.The present invention relates to a power regulator that detects the input current of the heating device and the AC motor so that overcurrent does not flow.

종래의 전력조절기는 열전대나 더어미스터(Thermister)등의 감온소자를 전열기나 모터등의 전기제품에 직접 부착하여 놓고 감온소자의 출력신호의 변화에 의하여 전기제품에 입력되는 전류가 조절되게 하였으므로, 감온소자를 전기제품에 추가로 설치해야 하며 또한 감온소자와 전류조절회로를 연결하여야 하는 번거로운 문제점이 있었다.In the conventional power regulator, a thermocouple such as a thermocouple or thermister is directly attached to an electrical appliance such as a heater or a motor, and the current input to the electrical appliance is controlled by a change in the output signal of the thermosensitive element. In addition, the device has to be additionally installed in an electric product, and there is a troublesome problem of connecting the thermosensitive device and the current control circuit.

본 고안은 이와같은 폐단을 제거하여 감온소자를)전기제품에 설치하지 않아도 입력전류를 조절할 수 있게 한 것으로 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention removes this closed end so that it is possible to control the input current without installing the thermosensitive element in the electrical product.

트라이악(1) 및 쵸우크 코일(2)을 통하여 부하(R/I)에 입력전류가 흐르도록 하고 트라이악(1)의 게이트에 다이악(2) 및 저항(R2), (R3) 그리고 콘덴서(C1)로서 구성된 통상의 점호회로를 연결하여 일정한 도통각을 갖고 점호되게 한 공지의 것에 있어서, 트라이악(1)의 방열판(4) 일측에 더어미스터(5)를 부착하고 이를 콘덴서(C2)와 직렬 접속하여 셀랙터 스위치(S)를 A측으로 하였을때 저항(R2)및 더어미스터(Ther mister)(5) 및 콘덴서(C1), (C2)에 의하여 트라이악(1)의 도통각이 결정되게 하고 셀랙터 스위치(S)를 B측으로 하였을 때에는 저항(R2), (R3) 및 콘덴서(C1)에 의하여 트라이악(1)의 도통각이 결정되게 하며, 트라이악(1)의 양단에 인가된 교류전압이 저항(R1) 및 다이오드(D1) 그리고 콘덴서로서 평활된 후 발광소자(LED)에 가해지도록 된 것이며 미설명부호 P1, P2는 교류전원 입력단자이며, P1', P2'는 부하연결 접속구이고 콘덴서(C4) 및 저항(R4)은 첨두치전압, 전류흡수 회로이다. 이와같이 된 본 고안의 작용 효과를 설명하면 다음과 같다. 먼저 제3도에 보인바와 같이 셀랙터 스위치(S)를 A측으로 하고 전원을 입력시키면 입력된 전압은 저항(R2)와 셀랙터 스위치(S)를 거쳐서 더어미스터(5)와 콘덴서(C2), (C1)에 가해지므로 이때의 시정수는 콘덴서(C2),(C1)의 용량을 합한 값과 더어미스터(5)의 저항 성분을 곱한 값으로 결정되고 이는 다이악(3)을 거쳐서 트라이악(1)의 게이트에 입력되어 그 도통각을 결정하게 되므로 결과적으로 부하(R/L)에 흐르는 전류량을 조절하게 되는 것이다. 예를 들면 어떤 요인으로 인하여 부하의 소비전류가 증가하였을 때에는 트라이악(1)에서 그 전류의 증가분만큼 발열하게 되고 따라서 그 방열판(4)에 부착된 더어미스터(5)는 열을 받아 결국 소비전력의 증가에 비례하여 저항 성분이 감소된다. 따라서 더어미스터(5)의 저항성분은 거의 무시되고 콘덴서 (C2, (C1) 및 저항(R2)만으로 그 시정수가 결정되며 이 신호가 다이악(3)을 통하여 트라이악(1)에 가하여져 그 도통각이 대폭 줄어들게 되어 부하(R/L)에 흐르는 전류의 값은 격감된다.The input current flows through the triac (1) and choke coil (2) to the load (R / I), and the diaac (2) and the resistors (R2), (R3) and In the well-known thing which connected the normal firing circuit comprised as the capacitor | condenser C1, and made it to be carried out with a constant conduction angle, the thermistor 5 was attached to one side of the heat sink 4 of the triac 1, and this was condenser C2. When the selector switch S is set to the A side in series connection, the conduction angle of the triac 1 is reduced by the resistor R2, the ther mister 5, and the capacitors C1 and C2. When the selector switch S is set to the B side, the conduction angle of the triac 1 is determined by the resistors R2, R3, and condenser C1, and at both ends of the triac 1 The applied AC voltage is applied to the light emitting device (LED) after smoothing as the resistor (R1), the diode (D1) and the capacitor. A source input terminal, P1 ', P2' are connected to the connection port and the load capacitor (C4) and a resistor (R4) is a peak-to-peak voltage, the current absorbing circuit. Referring to the effect of the present invention made as described above are as follows. First, as shown in FIG. 3, when the selector switch S is set to the A side and power is input, the input voltage passes through the resistor R2 and the selector switch S, and the demister 5, the capacitor C2, Since the time constant is added to (C1), the time constant at this time is determined by multiplying the capacitance of the capacitors (C2) and (C1) by the resistance component of the demister (5), which is passed through the triac (3) Since the conduction angle is determined by being input to the gate of 1), the amount of current flowing through the load R / L is adjusted. For example, when the current consumption of the load increases due to a certain factor, the triac 1 generates heat by an increase of the current, so that the demister 5 attached to the heat sink 4 receives heat and eventually consumes power. In proportion to the increase of the resistance component decreases. Therefore, the resistance component of the thermistor 5 is almost ignored and the time constant is determined only by the capacitors C2, (C1) and resistor R2, and this signal is applied to the triac (1) through the diaak (3). The conduction angle is greatly reduced, and the value of the current flowing through the load R / L is greatly reduced.

이와 같이하여 본 고안은 부하(R/L)를 과전류로부터 보호하게 되는 것이며, 셀랙터 스위치(S)를 B측으로 하면 이번에는 저항(R2), (R3)의 저항값과 콘덴서(C1)의 용량을 곱한 값으로 시정수가 결정되어 트라이악(1)의 도통각은 소정의 값으로 고정되는 것이어서 부하(R/L)에는 일정한 값을 공급하게 되는 것이다. 그리고 트라이악(1)의 양단에 인가된 교류전압을 저항(R1) 및 다이오드(D1) 그리고 콘덴서(C3)로써 정류시키고 평활시켜 발광소자(LED)를 점등 시킴으로써 전원표시등의 역활을 함과 동시에 그밝기는 트라이악(1) 양단의 인가전압에 따라 변화하게 되어 본 고안의 동작 상태를 표시하는 역활도 하게 된다.In this way, the present invention protects the load R / L from overcurrent. When the selector switch S is turned to the B side, this time, the resistance values of the resistors R2 and R3 and the capacitance of the capacitor C1 are used. The time constant is determined by multiplying and the conduction angle of the triac 1 is fixed to a predetermined value to supply a constant value to the load R / L. The AC voltage applied to both ends of the triac 1 is rectified and smoothed by the resistor R1, the diode D1, and the capacitor C3, and the LED is turned on to act as a power indicator. The brightness is changed according to the applied voltage across the triac (1), and also serves to display the operating state of the present invention.

이와 같이하여 본 고안은 감온소자를 전기제품에 직접 부착하지 않고도 부하의 소비전력을 조절할 수 있으므로 설치가 극히 용이하여 사용이 편리하게 되는 유용한 고안이다.In this way, the present invention is a useful design that makes the installation extremely easy to use because the power consumption of the load can be adjusted without directly attaching the thermostat to the electrical appliance.
