본 고안은 가정용 전기절감 장치에 관한 것으로 전압강하 및 역률개선 효과를 동시에 얻을수 있는 상호유도 리액터를 사용하되 부하측의 수요전류량이나 입력전원의 상태를 판단하여 자동적으로 입력전력를 직접 부하에 연결시켜 부하기기를 보호 할 수 있는 것을 특징으로 하는 자동바이패스기능이 장착된 가정용 전기절감장치에 관한 것이다The present invention relates to an electric power saving device for home use, which uses mutual induction reactor which can obtain the effect of voltage drop and power factor improvement at the same time, and automatically connects the input power directly to the load by judging the demand current amount or the state of the input power on the load side. Electric home saving device equipped with an automatic bypass function characterized in that it can protect

상호유도 리액터의 원리는 자가유도 상호작용을 이용한 리액터로서 부하측에 적정전압을 강하시켜 공급함으로써 절전효과를 얻고, 또한 역률을 개선시켜 절전효과를 얻을 뿐만아니라 부하측에 공급되는 전원은 파형(노이즈포함)을 정형시켜주고 급격한 돌입, 써지전압을 평활시켜주는 기능을 갖고 있다.The principle of the mutual induction reactor is a reactor using self-induction interaction, which provides a power saving effect by dropping and supplying an appropriate voltage to the load side, and also improves power factor to obtain a power saving effect, and the power supplied to the load side is waveform (including noise). It has the function of shaping and smoothing sudden inrush and surge voltage.

그러나 이러한 상호유도 리액터만으로는 입,출력 전압관계를 부하조건이나 입력전압상태에 따라 적절히 대응시킬수 없기 때문에 일정한 부하조건외에는 폭넓은 부하조건과 전원사정에 맞추어 사용하는데 실용적인 문제가 있을뿐아니라 저전압 및 과전류에 의거 부하기기가 파곤되는 등 안전에 많은 문제가 있었다.However, since these inductive reactors alone cannot adequately match the input and output voltage relationships according to the load conditions or the input voltage conditions, there are practical problems in using them under a wide range of load conditions and power supply conditions. There have been many problems with safety, such as the failure to load.

즉 모터운전과 같은 부하변동이 심한 경우 정상운전시에는 보통 부하율이 모터 정격의 60∼70％수준이기 때문에 일정 전압을 강하시키고, 역률을 개선시킬 경우 모터의 운전을 정상적으로 유지시키면서 상당한 절전효과를 얻을수 있지만 기동시에나 갑자기 부하율이 높아졌을 경우 충분한 전력공급을 위해 전압을 상승시켜 주거나 전원전압을 100％공급할 필요가 있다. 또한 입력전원이 일정전압이하로 떨어질 경우에 상호유도 리액터를 통한 부하측 전압이 정상적인 운전에 지장을 초래 할 만큼 전압강하가 일어나므로 이 경우에도 전압을 상승시켜주거나 전원전압을 100％공급할 필요가 있다.In other words, in case of heavy load fluctuation such as motor operation, in normal operation, since the load ratio is usually 60 ~ 70% of the motor rating, if a certain voltage drops, and the power factor is improved, a significant power saving effect can be obtained while maintaining the motor operation normally. When starting up or suddenly increasing the load rate, it is necessary to raise the voltage or supply 100% of the power supply voltage for sufficient power supply. In addition, when the input power drops below a certain voltage, the voltage drop occurs so that the load-side voltage through the mutual induction reactor may interfere with normal operation. Therefore, it is necessary to increase the voltage or supply 100% of the power supply voltage.

이에 본 고안의 목적은 상술한 문제점을 해결함에 있어서 상호유도 리액터의 작동 특성을 이용한 제어장치를 창출하여 상호유도 리액터의 절전특성을 실용화시키고, 입력전압 및 전류를 측정하여 자동적으로 입력전력를 직접 부하에 연결시켜 부하기기를 보호 할 수 있는 관련 제어기술은 제공하기 위한 것이다.Accordingly, an object of the present invention is to solve the above problems by creating a control device using the operating characteristics of the mutual induction reactor to realize the power saving characteristics of the mutual induction reactor, and to measure the input voltage and current to automatically input the input power directly to the load. It is to provide related control technology that can connect and protect the load.

본 고안의 첨부한 도면에 따라 상세히 설명한다.It will be described in detail according to the accompanying drawings of the present invention.

제 1도에 도시한 상호유도 리액터(4)는 입력전원(1)에 대해 병렬로 1차측 전압코일(2)과 2차측 전류코일(3)이 전자기적으로 결합되어 있고, 2차측 전류코일(3)은 부하(5)회로와 직렬로 연결되어 있다.In the mutual induction reactor 4 shown in FIG. 1, the primary side voltage coil 2 and the secondary side current coil 3 are electromagnetically coupled in parallel with respect to the input power source 1, and the secondary side current coil ( 3) is connected in series with the load 5 circuit.

또한 1차측 전압코일(2)의 권선(n1)은 입력전원(1)의 전압(V1)에 의해 결정되고 2차측 전류코일(3)의 권선(n2)은 임의의 적정전압강하량(VZ)에 따라 결정한다.In addition, the winding n 1 of the primary side voltage coil 2 is determined by the voltage V 1 of the input power source 1, and the winding n 2 of the secondary side current coil 3 has any appropriate voltage drop amount ( V Z ).

이때 출력전압(V2)은 V1-VZ로 결정되며 VZ × I2만큼의 전력량이 상호유도작용으로 1차측 전원(1)으로 궤환되어 절전이 되므로 역률개선 효과를 제공한다.At this time, the output voltage (V 2 ) is determined by V 1 -V Z and the power amount of V Z × I 2 is fed back to the primary power source 1 by mutual induction, thereby saving power.

그러나 이와같은 상호유도 리액터(4)는 부하(5)의 정상적인 작동전압범위가 200±15％일 경우 187 ∼ 253V 전압 범위가 히용되지만 예를 들어 2차측 전류코일(3)의 전압(VZ)이 15V이고 입력전원(1) 전압이 190V일 경우 부하(5)에 공급되는 전 압은 175V밖에 되지 않는다. 이럴 경우 절전효과 보다는 부하가 정상적인 일을 할수 없게 되므로 이런 경우 최소한 입력전원(1)을 직접 부하측에 연결할수 있는 수단이 필요하다.However, such a mutually inductive reactor 4 has a voltage range of 187 to 253V when the normal operating voltage range of the load 5 is 200 ± 15%, but for example, the voltage of the secondary current coil 3 (V Z ). Is 15V and the voltage of the input power source 1 is 190V, the voltage supplied to the load 5 is only 175V. In this case, the load cannot work normally rather than the power saving effect. In this case, at least a means of directly connecting the input power source 1 to the load side is required.

한편 부하(5)가 급격한 부하변동이나 과부하로 대전류를 필요로 할 때 2차측전류코일(3)에 흐르는 전류도 크게 증가하게되고 이때 2차측 전류코일전압(VZ)이 크게 증가하므로 부하측 출력전압(V2)은 그 만큼 감소하여 부하(5)측 수요전력을 충족시키지 못하게 된다.On the other hand, when the load 5 requires a large current due to a sudden load change or an overload, the current flowing in the secondary side current coil 3 also increases greatly, and at this time, the secondary side current coil voltage V Z increases greatly, thus the load side output voltage. (V 2 ) decreases so much that it cannot meet the demand power of the load 5 side.

이럴경우도 상호유도 리액터(4)의 절전기능 발휘에 대한 역기능이 제공되므로 실용상 문제가 있을 것이다.Even in this case, since the reverse function is provided for the power saving function of the mutual induction reactor 4, there will be a practical problem.

본 고안의 제어구성 개념은 1차측 전압코일(2)에 병렬 연결된 입력전원(1)을 1차측 전압코일(2)의 중간탭(12)을 통해 1차측 전압을 검출비교제어 할수 있는 1차측 전압검출제어수단(6)을 구성시켜 입력정눠(1)의 변동을 감시하고, 2차측 전류코일(3)에 흐르는 전류(I2)량을 감시하기 위해 전류코일전압(VZ)을 검출비교제어 할수 있는 2차측전류코일 전압검출제어수단(7)을 구비하여 각 수단(6)(7)의 출력신호에 따라 부하(5)에 입력전원(1)이 직접 공급되게 하거나 상호유도 리액터(4)의 2차측 전류코일(3)과 직렬로 연결시키는 스위치 절환수단의 접점단자(27.28)를 구성시켜서 입력전원(1)과 부하조건의 상황에 따라 적절히 대응할수 있는 기능을 부여한 것이다.The concept of the control structure of the present invention is that the primary side voltage capable of detecting and controlling the primary side voltage through the middle tap 12 of the primary side voltage coil 2 with the input power source 1 connected in parallel to the primary side voltage coil 2. The detection control means 6 is configured to monitor the variation of the input sorting 1 and to detect and compare the current coil voltage V Z to monitor the amount of current I 2 flowing in the secondary side current coil 3. A secondary side current coil voltage detection control means (7) capable of supplying the input power (1) directly to the load (5) or mutually inducing reactor (4) in accordance with the output signal of each means (6) (7). The contact terminal (27.28) of the switch switching means connected in series with the secondary side current coil (3) is configured to give a function capable of appropriately responding to the situation of the input power source 1 and the load conditions.

먼저 입력전원(1)의 전압이 제2도(a)의 정격전압(10)보다 기준전압(11,VIL) 이하로 될 경우 부하회로가 자동으로 입력전원에 직결되도록 하는 제어방법을 제1도의 본 고안 절전장치 일 구성도에 따라 설명한다.First, when the voltage of the input power source 1 becomes less than the reference voltage (11, V IL ) than the rated voltage 10 of FIG. The present invention will be described according to one configuration of the power saving device.

상호유도 리액터(4)의 1차측 전압코일(2)에 일정전압을 검출키 위한 중간탭(12)을 인출하고 그 인출선과 1차측 전압코일(2) 권선(n1) 시작(.)라인 사이의 전압을 공지의 브릿지 정류장치(15)에서 정류, 평활하고 정류된 직류전압을 비교전압으로 하되 기준전압(23: VIL)에 대한 히스테리시스 동작점을 갖도록 공지의 히스테리시스 회로를 구성시키고 그 출력을 비교증폭기(18)의 부(-)입력 (으)로 인가한다.Draw an intermediate tap 12 for detecting a constant voltage to the primary side voltage coil 2 of the mutual induction reactor 4, and between the lead line and the starting line of the primary side voltage coil 2 winding n 1 . A known hysteresis circuit is configured to have a hysteresis operating point with respect to a reference voltage (23: V IL ) as a comparison voltage, but the rectified, smoothed and rectified DC voltage is compared at a known bridge stop 15. It is applied as negative input of comparative amplifier 18.

그리고 기준전압(23: VIL)을 정(+) 입력(으)로 인가한다.The reference voltage 23 V IL is applied to the positive input.

이와같은 회로구성(15)(17)(18)에 의한 제어특성은 제3도a와 같이 실현된다.Such control characteristics by the circuit configurations 15, 17 and 18 are realized as shown in FIG.

즉, 입력전원(1)의 1자측전압(V1)이 비교기(18)의 정(+)입력에 인가된 기준전압(23: VIL) 보다 낮은 전원전압이 정류되어 비교기(18)의 부(-)입력에 인가될 경우 비교기(18)의 출력은 H상태를 출력한다.That is, the power supply voltage of which the one-side voltage V 1 of the input power supply 1 is lower than the reference voltage 23 V IL applied to the positive input of the comparator 18 is rectified, so that the negative voltage of the comparator 18 is rectified. When applied to the negative input, the output of the comparator 18 outputs an H state.

이 출력이 OR게이트의 한 입력에 인가되면 OR게이트 출력은 이 H상태를 출력하고 이때 파워 릴레이(26)는 ON되고, NOT게이트(22)를 거친 출력은 L상태가 되어 파워 릴레이(25)는 OFF된다. 따라서 부하입력라인(29)은 입력전원(1)과 직결될수 있는 릴레이(26)의 접점단자(27)와 연결된다.When this output is applied to one input of the OR gate, the OR gate output outputs this H state. At this time, the power relay 26 is turned ON, and the output passing through the NOT gate 22 is turned to L state, and the power relay 25 is OFF. Therefore, the load input line 29 is connected to the contact terminal 27 of the relay 26 that can be directly connected to the input power source (1).

반대로 기준전압(VIL)이상의 정상적인 전압이 인가될 경우 히스테리시스 입력특성에 저전압 검출제어전압보다 다소 높은 전압에서 비교앰프(18)의 출력이 L상 태로 되고, 파워 릴레이(25: TRY)가 ON되고 부하 입력라인(29)은 릴레이(25)의 접점단자(28)로 연결되어 정상적인 절전 운전을 할수 있게 한다.On the contrary, when a normal voltage higher than the reference voltage V IL is applied, the output of the comparison amplifier 18 becomes L at a voltage slightly higher than the low voltage detection control voltage in the hysteresis input characteristic, and the power relay 25 (T RY ) is turned on. The load input line 29 is connected to the contact terminal 28 of the relay 25 to enable normal power saving operation.

한편 부하측의 전류가 증가했을 때 2차측 전류코일(3)의 전압(VZ)변동에 따른 부하전류 검출제어방법을 설명한다.On the other hand, the load current detection control method according to the voltage V Z variation of the secondary side current coil 3 when the current on the load side increases.

제1도에 도시된 상호유도 리액터(4)의 2차측 전류코일(3)을 부하(5)측과 직렬로 연결되어 있기 때무에 부하(5)측 부하전류가 많이 흐를 경우 2차측 전류코일(3)의 전류(I2)가 증가하고 전류코일전압(VZ)은 E(VZ)=I.R법칙에 따라 전류에 비례하여 증가한다.Since the secondary side current coil 3 of the mutually induced reactor 4 shown in FIG. 1 is connected in series with the load 5 side, the secondary side current coil ( The current (I 2 ) of 3) increases and the current coil voltage (V Z ) increases in proportion to the current according to E (V Z ) = IR law.

이와같은 전류(I2)와 전류코일전압(VZ)의 관계를 제2도 b에 나타내었다.The relationship between the current I 2 and the current coil voltage V Z is shown in FIG.

본 고안은 별도의 전류검출장치를 사용하지 않고 2차측 전류코일(3)에서 전류코일전압(VZ)을 직접 검출하여 일정 한계이상의 기준전압(VZL)이상이 되면 입력전원(1)에 부하(5)회로가 직결되도록 제어장치를 구성시킨다.The present invention directly detects the current coil voltage (V Z ) at the secondary side current coil (3) without using a separate current detector, and loads the input power supply (1) when the reference voltage (V ZL ) is above a predetermined limit. (5) The control device is constructed so that the circuit is connected directly.

이와같은 착상에 의해 구성된 본 고안의 부하전류 검출제어방법은 제1도의 2차측 전류코일(3)의 양단(13.14)의 전압을 브릿지 정류장치(16)로 전파정류하고, 그 정류전압을 비교앰프(19)의 부(-)입력에 연결하고 기준전압(24, VIL)을 정(+)입력에 연결한다.The load current detection control method of the present invention constituted by such an idea is to perform full-wave rectification of the voltage at both ends 13.14 of the secondary side current coil 3 of FIG. 1 to the bridge stop value 16, and compare the rectified voltage with the comparison amplifier. Connect to negative input of (19) and connect reference voltage (24, V IL ) to positive (+) input.

그러므로 2차측 전류코일전압(VZ)이 정류장치(16)에 의해 전파정류되면 제5도(b)와 같이 출력되고 예를들어 모터 기동시와 같은 부하전류가 증가할 경우 기준 전압(VZL)보다 높은 전류코일전압(VZ)이 비교앰프(19)에 인가되어 비교앰프(19)출력이 H상태로 된다.Therefore, when the secondary side current coil voltage V Z is full-wave rectified by the stop value 16, it is output as shown in FIG. 5 (b), and when the load current increases, for example, when the motor is started, the reference voltage V ZL ) than is comparison amplifier (19 is the high current coil voltage (V Z), the comparison amplifier 19) to the output is H state.

정상 운전시는 전류코일전압(VZ)이 낮아져서 기준전압(VZL)보다 낮을 경우 비교앰프(19)출력은 L상태로 된다.In the normal operation, when the current coil voltage V Z is lowered and lower than the reference voltage V ZL , the output of the comparison amplifier 19 is in the L state.

따라서 비교앰프(19)의 출력이 H일 경우, 즉 모터기동과 같은 많은 전류가 흐르게 될 경우 릴레이(26: TRY)가 ON되고 부하입력라인(29)은 릴레이(26)의 접점단자(27)에 연결되므로 입력전원(1)과 직접 연결된다.Accordingly, when the output of the comparison amplifier 19 is H, that is, when a large amount of current such as a motor starts to flow, the relay 26 T RY is turned on and the load input line 29 is connected to the contact terminal 27 of the relay 26. ) Is directly connected to the input power source (1).

그러므로 부하측에 충분한 전력을 공급할수 있게되고 적정전류이하로 부하 전류가 떨어지게 되면 릴레이(25: TRY)가 ON되고 부하입력라인(29)은 릴레이(25)의 접점단자(28)에 연결되므로 절전 운전을 할수 있는 것이다.Therefore, when enough power can be supplied to the load side and the load current falls below a proper current, the relay 25 (T RY ) is turned on and the load input line 29 is connected to the contact terminal 28 of the relay 25 to save power. You can drive.

한편, 릴레이(25)(26)는 파워반도체스위칭소자를 사용할수도 있다.On the other hand, the relays 25 and 26 may use power semiconductor switching elements.

이와같이 구성된 본 고안은 상호유도 리액터의 절전특성을 실용화 할수 있게 하고 입력전원변동과 부하변동에 따른 전력공급을 원할히 함으로써 부하측의 정상 운전 또는 정상작동에 지장을 전혀 초래하지 않고 입력전원이 바로 부하에 연결하도록하여 부하기기를 보호하여 안전성을 확보할 수 있는 가정용 잔기절감장치를 제공할수 있는 것이다.In this way, the present invention can realize the power saving characteristics of the mutual induction reactor and the power supply according to the input power variation and the load variation can be realized, so that the input power is directly connected to the load without any disruption to the normal operation or normal operation of the load side. It is possible to provide a domestic residue reduction device that can ensure the safety by protecting the load.
