이하 첨부된 도면을 참조하여 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제1도를 참조하여 설명하면, 전원입력부(10)에는 릴레이구동부(20)와 릴레이스위치부(30)가 접속된다. 상기 릴레이구동부(20)는 전원입력부(10)로부터 90V∼132V의 전압이 인가되면 동작하지 않고, 180V∼264V가 입력되면 동작하여 릴레이스위치부(30)를 구동시킨다.Referring to FIG. 1, the relay driving unit 20 and the relay switch unit 30 are connected to the power input unit 10. The relay driver 20 does not operate when a voltage of 90V to 132V is applied from the power input unit 10, and operates when 180V to 264V is input to drive the relay switch unit 30.
상기 릴레이스위치부(30)는 90V∼132V의 전압이 릴레이구동부(20)에 인가되었을때는 온(ON)상태를 유지하는 제3 및 제4릴레이스위치부(34)(38)와, 180V∼264V의 전압이 릴레이구동부(20)에 인가되었을때 온(ON)상태를 유지하는 제1및 제2릴레이스위치부(32)(36)로 이루어져 있으며, 트랜스부(40)는 상기 릴레이스위치부(30)에 접속되어 제1및 제2릴레이스위치부(32)(36)와 제3. 및 제4릴레이스위치부(34)(38)의 연계동작에 의해 출력부(50)에 110V 또는 220V의 전압을 인가시킨다.The relay switch unit 30 includes the third and fourth relay switch units 34 and 38 that maintain an ON state when a voltage of 90 V to 132 V is applied to the relay driver 20, and 180 V to 264 V. It is composed of the first and second relay switch unit 32, 36 to maintain an ON state when the voltage is applied to the relay driver 20, the transformer unit 40 is the relay switch unit 30 And the first and second relay switch portions 32, 36 and 3. And a voltage of 110V or 220V to the output unit 50 by the interlocking operation of the fourth relay switch units 34 and 38.
일실시예를 통해 좀더 상세히 설명하면, 전원입력부(10)를 통해 90V∼132V가 입력되면 릴레이구동부(20)는 동작을 하지 않으므로 제1릴레이스위치부(32)와 제2릴레이스위치부(36)는 오프(Off) 상태가 되며, 제3릴레이스위치부(34)와 제4릴레이스위치부(38)는 온(ON)상태를 유지하게 된다.In more detail through one embodiment, when the 90V ~ 132V is input through the power input unit 10, the relay driver 20 does not operate, so the first relay switch unit 32 and the second relay switch unit 36 Is in an off state, and the third relay switch unit 34 and the fourth relay switch unit 38 are maintained in an ON state.
따라서 입력된 저전압(90V∼132V)은 제3릴레이스위치부(34)를 통해 트랜스부(40)의 제1점점(42)에 인가되고, 상기 제1접점(42)에 인가된 저전압은 제2접점(44) 및 고전압출력표시램프(74)에 인가되며, 이때 제1접점(42)에서 제2접점(44)으로 인가된 저전압은 고전압으로 승압되어 제4릴레이스위치부(38)를 통해 출력부(50)로 출력된다.Therefore, the input low voltage (90V to 132V) is applied to the first point 42 of the transformer unit 40 through the third relay switch unit 34, the low voltage applied to the first contact 42 is the second The low voltage applied to the contact point 44 and the high voltage output display lamp 74 is increased from the first contact point 42 to the second contact point 44 and is outputted through the fourth relay switch unit 38. Output to the unit 50.
전원입력부(10)를 통해 180V∼264V가 입력되면 릴레이구동부(20)가 동작을 하여 제1릴레이스위치부(32)와 제 2 릴레이스위치부(36)는 온(ON)상태로 절환이 되며, 제 3 릴레이스위치부(34)와 제 4 릴레이스위치부(38)는 오프(Off)상태로 절환이 된다.When 180V to 264V is input through the power input unit 10, the relay driving unit 20 operates to switch the first relay switch unit 32 and the second relay switch unit 36 to an ON state. The third relay switch unit 34 and the fourth relay switch unit 38 are switched to the off state.
따라서 입력된 고전압(180V∼264V)은 제1릴레이스위치부(32)를 통해 트랜스부(40)의 상기 제2접점(44)에 인가되고, 상기 제2접점(44)에 인가된 고전압은 제1접점(42)과 저전압출력표시램프(72)에 인가되며, 상기 제1접접(42)에 인가된 고전압은 저전압으로 절환되어 제2릴레이스위치부(36)를 통해 출력부(50)에 출력되게 된다.Accordingly, the input high voltage 180V to 264V is applied to the second contact 44 of the transformer 40 through the first relay switch 32, and the high voltage applied to the second contact 44 The high voltage applied to the first contact point 42 and the low voltage output display lamp 72 is switched to the low voltage and output to the output unit 50 through the second relay switch unit 36. Will be.
이상 설명에서 알 수 있는 바와같이, 본 발명은 입력된 전압값에 따라 구동되는 릴레이구동부를 이용하여 고전압이 입력되면 저전압이 출력되고 저전압이 입력되면 고전압이 출력되게 하므로서 고전압용 변압기와 저전압용 변압기를 별도로 구입하지 않아도 되는 효과가 있다.As can be seen from the above description, the present invention provides a high voltage transformer and a low voltage transformer by outputting a low voltage when a high voltage is input and a high voltage when a low voltage is input using a relay driver driven according to the input voltage value. There is no need to purchase separately.
