In the drawings referred to in the present invention, components having substantially the same configuration and function will use the same reference numerals.
도 2는 본 발명에 따른 플라이백 트랜스포머의 회로구성도로서, 도 2를 참조하면, 본 발명에 따른 플라이백 트랜스포머는 수평출력부(11)의 동작에 따라 1차측 권선코일(L1)의 펄스성 전압을 2차측 권선코일(L2)로 승압하고, 이후 정류다이오드를 통해 정류한후 고압 커패시터(CH)를 통해 평활시킨후 이와같이 평활된 고압을 수상관의 애노드단에 제공하고, 또한 상기 고압을 다수의 저항을 통해서 분할하고, 이 분할된 전압을 적절히 조절하여 해당 포커스전압(VF)을 제공하며, 상기 1차측 권선코일(L1)에 고장방지용 저항(R)을 설치한다.FIG. 2 is a circuit diagram of a flyback transformer according to the present invention. Referring to FIG. 2, the flyback transformer according to the present invention has the pulse characteristics of the primary winding coil L1 according to the operation of the horizontal output unit 11. The voltage is boosted to the secondary winding coil L2, and then rectified through the rectifying diode and smoothed through the high voltage capacitor (CH). The smoothed high voltage is provided to the anode end of the water pipe. Split through the resistance of the, and by appropriately adjusting the divided voltage to provide the corresponding focus voltage (VF), the failure prevention resistor (R) is installed in the primary winding coil (L1).
상기 고장방지용 저항(R)은 일반 저항으로서, 상기 1차측 권선코일(L1)의 일단, 또는 타단에 설치할 수 있고, 또한 상기 1차측 권선코일(L1)의 중간에 직렬로 구성한다.The failure preventing resistor R may be provided as a general resistance at one end or the other end of the primary winding coil L1, and is configured in series in the middle of the primary winding coil L1.
이와같이 구성된 본 발명에 따른 동작을 첨부도면에 의거하여 하기에 상세히 설명한다.Operation according to the present invention configured as described above will be described in detail below based on the accompanying drawings.
도 2를 참조하여 본 발명을 설명하면, 수평출력부(11)의 동작에 따라 1차측 권선코일(L1)의 펄스성 전압을 2차측 권선코일(L2)로 승압하고, 이후 승압된 전압은 정류다이오드를 통해서 정류한후 고압 커패시터(CH)를 통해 평활시킨후 이와같이 평활된 고압을 수상관의 애노드단에 제공하고, 또한 상기 고압을 다수의 저항을 통해서 분할하고, 이 분할된 전압을 적절히 조절하여 해당 포커스전압(VF)을 제공한다.Referring to FIG. 2, the pulsed voltage of the primary winding coil L1 is boosted to the secondary winding coil L2 according to the operation of the horizontal output unit 11, and the boosted voltage is then rectified. After rectifying through a diode and smoothing it through a high voltage capacitor (CH), the smoothed high voltage is provided to the anode end of the water pipe, and the high voltage is divided through a plurality of resistors, and the divided voltage is adjusted appropriately. The corresponding focus voltage VF is provided.
이와같은 과정에서, 상기 1차측 권선코일(L1)에 과전류가 유입되는 경우에 있어서, 종류의 플라이백 트랜스포머는 이 과전류로 인하여 전연용 에폭시 수지가 부풀어올라 플라이백 트랜스포머가 폭발하는 문제점이 있었으나, 본 발명에서는 1차측 권선코일(L1)에 고장방지용 저항(R)이 부가됨에 의해서, 상기한 바와같이 1차측 권선코일(L1)에 과전류가 흐르면 상기 고장방지용 저항(R)이 오픈되며, 이에따라 1차측 권선코일(L1)이 오픈되므로, 플라이백 트랜스포머는 동작을 못하게 된다.In this process, when an overcurrent flows into the primary winding coil L1, a flyback transformer of the kind has a problem that the flyback transformer explodes due to swelling of the epoxy resin for inflation due to the overcurrent.

상기한 바와같이, 고장방지용 저항은 일반적인 저항으로서, 견딜수 있는 내전류보다 높은 전류가 저항내부에 흐르게 되면 과전류를 견디지 못하고 저항내부에서 전도선이 오픈되는 것이다.As described above, the failure preventing resistor is a general resistance, and when a current higher than the withstand current flows into the resistor, the conductive wire is opened without being able to withstand the overcurrent.
위에서 설명한 바와같이, 본 발명의 플라이백 트랜스포머의 1차측 권선코일(L1)에 과전류가 흐르면, 1차측 권선코일(L1)이 오픈되어 플라이백 트랜스포머의 동작이 정지되어 플라이백 트랜스포머가 폭발하는 것이 방지되는 것이다.As described above, when an overcurrent flows through the primary winding coil L1 of the flyback transformer of the present invention, the primary winding coil L1 is opened to stop the operation of the flyback transformer and prevent the flyback transformer from being exploded. Will be.
상술한 바와같은 본 발명에 따르면, 1차측 권선코일에 과전류가 흐를 때 1차측 코일을 오픈(OPEN)시키도록 함으로서, 과전류에 의해 플라이백 트랜포머가 폭발하는 것을 사전에 방지하도록 하는 특별한 효과가 있는 것이다.According to the present invention as described above, by opening the primary coil when an overcurrent flows in the primary winding coil (OPEN), there is a special effect to prevent the flyback transformer from explosion due to the overcurrent will be.
이상의 설명은 본 발명의 일실시예에 대한 설명에 불과하며, 본 발명은 그 구성의 범위내에서 다양한 변경 및 개조가 가능하다.The above description is only a description of one embodiment of the present invention, the present invention is capable of various changes and modifications within the scope of the configuration.
