본 고안은 잡음 차폐 변압기에 관한 것으로 특히 환상철심을 이용하여 전원선으로 입력되는 각종 라인 전도 잡음을 차폐하기에 적당하도록 한 것이다.The present invention relates to a noise shielding transformer, and particularly to shield various line conduction noises input to a power line using an annular core.
종래에는 제 1 도와 제 2 도에 도시된 바와같이 1차권선(1)을 환상철심(6)위에 권선한 후 차폐선(3)을 1차권선(1)의 총권선수와 같은 권선수로 하여 1/2씩 역방향(역직렬)으로 권선하였다.Conventionally, as shown in FIG. 1 and FIG. 2, the primary winding 1 is wound on the annular core 6, and the shielding wire 3 is the same number of turns as the total winding of the primary winding 1. Winding in reverse direction (reverse series) by half.
그리고, 차폐선(3)위에 2차권선(2)을 상기의 1차권선(1)처럼 균등히 권선한후 그 위에 차폐선(4)을 차폐선(3)과 동일하게 권선하였다.Then, the secondary winding 2 was wound on the shielding wire 3 evenly as in the primary winding 1 above, and then the shielding wire 4 was wound on the shielding wire 3 in the same manner as the shielding wire 3.
또한, 제 2 도와 같이 1차권선(1)과 2차권선(2)의 리드선(8)(9)을 각각 빼내어 이러한 차폐선(3)(4)의 4개 리드선을 동일극성끼리 접속 접지하였다.In addition, as shown in the second diagram, the lead wires 8 and 9 of the primary winding 1 and the secondary winding 2 were removed, respectively, and the four lead wires of the shielding wires 3 and 4 were connected to the same polarity. .
상기한 바와같은 종래의 기술에 있어서는 리드선(8)을 통하여 1차 권선(1)으로 입력되는 잡음은 1, 2차 권선(1)(2)간의 콘덴서(C1-C6)를 통하여 2차권선(2)으로 전도되는데 차폐선(3)을 접지하므로써 제 3 도와 같이 권선간의 정전용량을 줄이고 권선과 대지간의 대지정전 용량을 만들므로 1차권선(1)으로 입력되는 잡음을 콘덴서(C1-C6)를 통하여 대지로 바이패스 시켰다.In the prior art as described above, the noise input to the primary winding 1 through the lead wire 8 is secondary through the capacitors C 1 -C 6 between the primary and secondary windings 1 and 2. winding (2) there is conducted to the shield (3), so reducing the capacitance between the windings, as a third help by ground to make the ground capacitance between the winding and the ground capacitor for the noise that is input to the primary winding (1) (C 1 -C 6 ) was bypassed to the ground.
또한, 차폐선(4)은 외부전계 및 자계의 영향이 2차권선(2)에 미치는 것을 방지하기 위한 것이며 이러한 차폐선(3)(4)이 각각 역직렬로 권선되어 있으므로 리드선(8)(9)으로 병렬 접속되어 있어도 순환전류가 발생하지 않는다.In addition, the shielding wire 4 is for preventing the influence of the external electric field and the magnetic field on the secondary winding 2, and since the shielding wires 3 and 4 are respectively wound in series, the lead wire 8 ( Circulating current does not occur even when connected in parallel.
그러나, 종래에는 차폐선(3)(4)만을 장치하여 1, 2차권선(1)(2)간의 정전용량이 감소됨은 물론 잡음전도를 방지하기가 어렵고 1, 2차 권선(1)(2)간의 정전용량이 수백 PE이상이 되어야 했으며 차폐선(3)(4)을 직접 접지하므로 고주파 잡음 바이패스 회로로는 부적당할 뿐만 아니라 다중 차폐구조가 아니므로 잡음 차폐능력이 크게 떨어지는 결점이 있었다.However, in the related art, only the shielding lines 3 and 4 are provided so that the capacitance between the primary and secondary windings 1 and 2 is reduced, and it is difficult to prevent noise conduction. Since the capacitance between them should be more than several hundred PE, and the shield wires (3) and (4) are directly grounded, they are not only unsuitable for high-frequency noise bypass circuits, but also have a disadvantage in that the noise shielding capability is greatly reduced because they are not multi-shielded structures.
본 고안은 이와같은 종래의 결점을 감안하여 안출한 것으로 이를 첨부된 도면 제 4 도와 제 5 도에 의하여 상세히 설명하면 다음과 같다.The present invention has been devised in view of the above-described drawbacks and will be described in detail with reference to FIGS. 4 and 5 of the accompanying drawings.
본 고안은 환상철심(6)위에 1차권선(1)을 전체 자로장에 균등하게 권선하고 그 위에 차폐선(3)을 동일하게 권선한다.The present invention evenly wound the primary winding (1) to the entire magnetic field on the annular iron core (6) and the same shielding wire (3) on it.
그리고, 이 차폐선(3)위에 간격을 두고 도전판(5)을 구성하여 단락이 되지 않도록 하며 절연판(7)을 사이에 두고 다른 도전판(5a)을 설치한후 2차권선(2)을 권선하고 그 위에 차폐선(4)을 권선한다.Then, the conductive plate 5 is formed on the shielding line 3 at intervals so as not to cause a short circuit, and the secondary winding 2 is connected after the other conductive plate 5a is provided with the insulating plate 7 interposed therebetween. Winding and winding shield line 4 thereon.
단, 각 권선은 환상철심(6)위에 균등히 권선하고 도전판(5)(5a)은 일정두께의 도전체로 된 박판을 이용하며 차폐선(3)은 상하내외의 전면을 완전히 감싸도록 구성한다.However, each winding is evenly wound on the annular core (6), the conductive plates (5) (5a) using a thin plate made of a conductor of a certain thickness, and the shielding line (3) is configured to completely surround the front and the outside of the top and bottom.
제 5 도는 본 고안의 결선도로 1차권선(1)과 2차권선(2)에 권선된 차폐선(3)(4)의 4개의 리드를 동일 극성끼리 접속 접지하되 일측리드는 직접 접지하고 다른 일측 리드는 콘덴선(C)를 통하여 접지한다.5 is a connection diagram of the present invention, the four leads of the shielding wire (3) (4) wound on the primary winding (1) and the secondary winding (2) are connected with the same polarity, but one lead is directly grounded and the other One lead is grounded through the condensation line (C).
도면중 미설명 부호 8, 9는 1, 2차 권선의 각 리드선으로 1차권선(1)은 리드선(8)을 통하여 전원측에 접속되어 있고 2차권선(2)은 리드선(9)을 통하여 부하기기에 접속되어 있다.In the drawing, reference numerals 8 and 9 are the respective lead wires of the primary and secondary windings, and the primary winding 1 is connected to the power supply side through the lead wire 8 and the secondary winding 2 is loaded through the lead wire 9. It is connected to a device.
이와같이 구성된 본 고안은 만일, 용접덥기, 전동기 기타 제어기기로부터 발생하여 전도되는 서지(SURGE)등의 잡음이 1차전선(1)으로 입력되면 환상철심(6)은 갭레스(GAPLESS)의 철심이므로 여자특성이 양호하고 저주파의 규소강판을 이용한 것이어서 고주파에서의 투자율이 크게 떨어져 고주파 잡음에 의한 유료자속분은 자기저항 증가에 의해서 극단적으로 감소하고, 이에따라 극소의 잡음자속이 2차권선(2)과 쇄교하므로 2차권선(2)의 리드선(9)에는 미소한 잡음 전압이 나타나게 된다.According to the present invention configured as described above, if noise such as surge generated from welding hot, electric motor or other control device is input to the primary wire 1, the annular core 6 is a gapless iron core. Since the excitation characteristics are good and low-frequency silicon steel is used, the permeability at high frequencies is greatly reduced, and the charged magnetic flux due to the high frequency noise is extremely reduced by the increase of the magnetoresistance. Thus, the minimum noise magnetic flux is reduced to the secondary winding (2). As a result, a small noise voltage appears in the lead wire 9 of the secondary winding 2.
따라서, 본 고안은 고주파 잡음에 의한 철심의 투자율 변화로 고주파 에너지를 철심의 손실분으로 소모하므로 잡음 흡수의 기능이 우수하여 1차권선(1)을 통한 잡음 차폐 능력이 높다.Therefore, the present invention consumes high frequency energy as a loss of the iron core due to the change in the permeability of the iron core due to the high frequency noise, so the noise absorption function is excellent and the noise shielding ability through the primary winding 1 is high.
또한, 본 고안은 차폐선(3)(4)을 장치하여 기본 주파수에서는 회로 전위와 같은 전위를 유지하지만 고주파 입력시 콘덴서(C)가 저 임피던스 회로를 구성하여 1차권선(1)에 입력된 고주파 잡음에 대응하는 역기전력을 발생시켜 고주파에 의한 자속을 억제하며 콘덴선(C1)가 저임피던스로 동작하므로 1차권선(1) 및 2차권선(2)간의 차폐역할을 겸하여 권선(1)(2)간의 정전용량을 저감시킨다.In addition, the present invention is equipped with shield (3) (4) to maintain the same potential as the circuit potential at the fundamental frequency, but at the high frequency input, the capacitor (C) constitutes a low impedance circuit is input to the primary winding (1) Generates counter electromotive force corresponding to high frequency noise to suppress magnetic flux caused by high frequency and condensation line (C 1 ) operates at low impedance, thus acting as shield between primary winding (1) and secondary winding (2), winding (1) ( 2) Reduce the capacitance of the liver.
그리고, 도전관(5)(5a)은 1, 2차 권선(1)(2)을 완전히 격리시키므로 1차 잡음에 의한 전계 및 자계 영향이 2차권선(2)에 미치는 것을 방지하고 1, 2차권선(1)(2)간의 정전용량을 극소화시키므로 1차 권선(1)과 대지간으로 입력되는 잡음이 1, 2차 권선(1)(2)간의 정전용량을 통하여 2차권선(2)으로 전도되는 것을 방지한다.In addition, the conductive pipes 5 and 5a completely isolate the primary and secondary windings 1 and 2, thereby preventing the electric and magnetic field effects caused by the primary noise from affecting the secondary winding 2. Since the capacitance between the primary windings (1) and (2) is minimized, the noise inputted between the primary winding (1) and the ground is reduced through the capacitance between the primary and secondary windings (1) and (2). To prevent it from falling.
따라서, 본 고안은 차폐선(3)(4) 및 도전판(5)(5a)을 이용하여 다중 차폐효과를 얻어 1, 2차권선(1)(2)간의 잡음 전도율을 극소화시켜서 1차권선(1)으로 입력되는 라인 잡음을 차폐 및 흡수할 수 있음은 물론 각종 전자기기를 라인 잡음으로부터 보호할 수 있을뿐만 아니라 차폐선(3)(4)을 직렬로 권선하여 종래보다 제조하기가 용이하고 차폐선(3)(4)과 콘덴(C)조합에 의한 고주파 바이패스가 가능한 효과가 있다.Therefore, the present invention obtains the multiple shielding effect by using the shielding line (3) (4) and the conductive plate (5) (5a) to minimize the noise conductivity between the primary and secondary windings (1) (2) to the primary winding Not only can shield and absorb the line noise input into (1), but also protect various electronic devices from line noise, and it is easier to manufacture by winding the shield lines (3) (4) in series. The high frequency bypass by the shield line 3, 4, and condensate (C) combination is possible.
