본 고안은8100V/220V 입력전원 자동절환장치에 있어서, 최초전원 인가시나 전원변동시에 기기에 공급되는 전원을 안정되게 공급시킬 수 있는 전원자동절환장치에 관한 것이다. 종래에도 100V나 220V의 전원변동시에 트랜스의 탭을 자동절환시켜 기기에 일정한 전원을 공급하는 장치로서 제3도와 같은 회로가 제안된바 있으나 이러한 경우는 릴레이(Ry)를 220V용으로 사용하여 입력전원이 220V일 때만 동작시켜 트랜스탭을 절환시키게 되는 것인데, 전원이 없는 상태 또는 100V전원이 인가되고 있을 때는 트랜스(Trans)의 100V 단자에 접속되어 있다가 220V가 인가될 때 렐리에 동작으로 탭을 절환시키게 되므로, 릴레이 스위치(SW')가 절환될 때까지는 순간적으로 100V단자에 접속되어 있는 상태에서 220V 전원이 인가되게 된다. 따라서 기기에 공급되는 전원이 절환되는 순간 급상승하여 기기의 손상을 초래하는 결정적인 요인이 되어 왔다.The present invention relates to an 8100V / 220V input power automatic switching device, the power automatic switching device that can stably supply the power supplied to the device when the first power is applied or the power fluctuation. Conventionally, a circuit as shown in FIG. 3 has been proposed as a device for supplying constant power to a device by automatically switching a tap of a transformer when a power supply of 100V or 220V changes, but in this case, a relay (Ry) is used for 220V input. It operates only when the power is 220V and switches the transformer.When there is no power or when 100V power is applied, it is connected to the 100V terminal of the trans and when the 220V is applied, Since switching is performed, 220V power is applied while being connected to the 100V terminal momentarily until the relay switch SW 'is switched. Therefore, it has been a decisive factor that suddenly rises when power supplied to the device is switched, causing damage to the device.
또한, 종래의 전원절환장치는 정류회로와 정전압회로가 반드시 있는 제품에서만 사용이 가능한 것으로 전원회로가 복잡하고 전축과 같은 전류기폭이 심한 전류가 많이 흐르는 기기와 정류회로가 없는 냉장고와 같은 기기에는 사용할 수 없는 것이며, 다용도로 사용하고잘할 때에는 부착하고자 하는 제품의 실정에 따라 회로가 변경되어야 사용할 수 있는 폐단이 있었다.In addition, the conventional power switching device can be used only in a product that has a rectifying circuit and a constant voltage circuit, and it is used for a device such as a refrigerator without a rectifying circuit and a device in which a power circuit is complicated and a large current amplification such as an electric shaft flows. It is impossible to use it, and when it is versatile and well used, the circuit has to be changed according to the situation of the product to be attached.
본 고안은 이러한 점을 감안하여 안출한 것으로서, 전원이 인가되지 않은 상태에서는 트랜스의 100V단자가 아닌 완전차단상태에 놓이도록 하고, 전원변동시에 대비하여 순간적인지 연동작을 시키도록 한 것으로 이를 도면에 의거 상세히 설명하면 다음과 같다.The present invention has been devised in view of the above points, and when the power is not applied, the transformer is placed in a completely cut-off state instead of the 100V terminal of the transformer, and a momentary delay operation is made in preparation for a power change. The detailed description is as follows.
즉, 제1도와 같이 전원트랜스(T)의 단자에 정류용 다이오드(D1,D4)를 연결하고, 다이오드(D1,D2)에는 220V전원인가시 도통되는 42V제너전압의 제너다이오드(Dz)와 저항(R1)을 거쳐 트랜지스터(Q1)의 베이스에 연결하여, 상기 트랜지스터(Q1)의 콜렉터에는 충전용 콘덴서(C3)를 연결하고, 제너다이오드(Dz)의 캐소오드접속점 사이에 저항(R3)을 연결하는 한편, 다링톤 결선형트랜지스터(Q2,Q3)를 연결하여 이의 출력단에 릴레이(L1)를 연결하고, 상기 트랜지스터(Q1)의 에미터에는 트랜지스터(Q4,Q5)를 거쳐 릴레이(L2)를 연결하며, 상기 릴레이(L1,L2)의 접속점을 릴레이스위치(SW)를 220V용 단자(b)로 절환시킨다.That is, as shown in FIG. 1, the rectifier diodes D 1 and D 4 are connected to the terminals of the power supply T, and the zener diodes of 42 V zener voltage which are conducted when 220 V power is applied to the diodes D 1 and D 2 are connected. Connect to the base of transistor Q 1 via Dz) and resistor R 1 , connect charging capacitor C 3 to the collector of transistor Q 1 , and connect the cathode of Zener diode Dz. While connecting a resistor (R 3 ) between, while connecting the Darlington connected transistor (Q 2 , Q 3 ) to connect the relay (L 1 ) to its output terminal, the transistor of the transistor (Q 1 ) The relay (L 2 ) is connected via (Q 4 , Q 5 ), and the connection point of the relay (L 1 , L 2 ) is switched to the relay switch (SW) to the terminal (b) for 220V.
한편, 입력전원이 100V로 인가되어 제너다이오드(Dz)의 캐소오드쪽에 42V의 제너전압보다 낮은 24V정도가 가해지면, 제너다이오드(Dz)의 차단으로 저항(R2)을 통한 트랜지스터(Q1)의 베이스전위는 낮아져서 트랜지스터(Q1)는 OFF되므로 트랜지스터(Q4,Q5)가 OFF되어 릴레이(L2)는 동작을 멈추게 되어 단자(b)에 있던 절환스위치(SW)는 무접점단자(c')로 절환되고, 트랜지스터(Q1)의 OFF로 인해 전원전류 저항(R3)을 거쳐 콘덴서(C3)에 충전되면서 트랜지스터(Q2)의 베이스전위가 높아지면 트랜지스터(Q2, Q3)가 ON되어 릴레이(L1)가 동작하게 된다. 이때, 단자(c')에 있던 스위치는 100V용 단자(a)로 절환되는 것이다.On the other hand, when the input power is applied at 100V and a voltage of about 24V lower than the zener voltage of 42V is applied to the cathode of the zener diode Dz, the transistor Q 1 through the resistor R 2 is blocked by the zener diode Dz. Since the base potential of the transistor is lowered, the transistor Q 1 is turned off, so the transistors Q 4 and Q 5 are turned off, and the relay L 2 is stopped. The switching switch SW at the terminal b is a contactless terminal ( c ') to be switched, due to the OFF of the transistor (Q 1) via the supply current resistance (R 3) a capacitor (C 3) a base potential of the transistor (Q 2) increases as charging the ground transistor (Q 2, Q 3 ) is turned on and the relay (L 1 ) is operated. At this time, the switch in the terminal c 'is switched to the terminal 100a for 100V.
이와같이, 입력전원에 따라 기기내에 이미 부착된 트랜스의 1차측 입력단자를 가동절환시키게 되므로 소정의 정격전원을 요하는 전자는 기기에 항상 안정된 전원을 공급시킬 수 있는 것으로서, 평상시 입력전원을 220V로 사용하고 있는 상황에서 한전 등으로부터의 전기공사도 중 실수로 인해 100V를 공급하는 경우에는 자동절환시간을 순간적으로 지연시키기 때문에 전원변동으로 인한 과전류로기기가 손상될 우려가 없으며, 특히 처음 전원공급시에 220V를 인가할 경우 종래에는 평상시에 트랜스의 100V 단자에 접속되어 있으므로 릴레이가 동작하여 220V단계로 절환시킬 때까지는 기기에 과전압이 걸려 기기가 손상될 우려가 있던 것을 본 고안에서는 트랜스이 무접점상태에 대기하고 있다가 입력전원을 받아 절환시키게 되는 것이므로 입력전원변동에 상관없이 기기가 안정되게 보호받을 수 있으며, 어느 제품이라도 전원 1차측이 0V, 100V, 220V의 배선만 되어, 있으면 기기내부의 트랜스가 있든 없든 어느 기기에라도 사용할 수 있을 뿐만 아니라 타기기전원의 내부가 복잡하거나 전원전압이 틀리거나 또는 정류회로의 유무에 상관없이 사용할 수 있는 특징을 지닌 것이다.In this way, since the primary input terminal of the transformer already attached to the device is switched according to the input power, the electronics requiring a predetermined rated power can always supply stable power to the device. In case of supplying 100V by mistake during the electric work from KEPCO, the automatic switching time is delayed momentarily, so there is no risk of damage to the device due to over current due to power fluctuation. In the case of applying 220V, the transformer is normally connected to the 100V terminal of the transformer, so that the device may be damaged due to the overvoltage of the device until the relay operates to switch to 220V. Input power and change the input power. The equipment can be protected stably regardless of the power supply, and if any product has only 0V, 100V, 220V wiring, it can be used for any device with or without transformer inside the device, It is a feature that can be used regardless of the complexity, incorrect power supply voltage, or the presence of a rectifier circuit.
