Abstract

본 발명은 전압의 크기의 변화시 자속누설을 감소시킬 수 있는 자동변압기에 관한 것이다. 이러한 본 발명은 3상의 전압을 인가받는 1차측과, 그에 대향하여 배치되고 코일의 권선비에 따라 전압을 승압 또는 강압시켜 출력하는 2차측을 구비하는 변압기에 있어서, 상기 1차측과 2차측은 각각 3이상의 전압 중 2상의 전압을 입력받는 사각형의 철심을 구비하며, 각 철심에는 제1상의 전압을 인가받는 코일이 좌측에 n회 권선된 후 연장되어 우측에 n회 권선되고 그와 동시에 제2상의 전압을 인가받는 코일은 우측에 m회 권선된 후 연장되어 좌측에 m회 권선되어 서로 부하조건이 다른 경우 언바란스로 인해 생기는 손실을 바란스화하여 트랜스포머의 손실을 저감하게 되는 것이다.The present invention relates to an automatic transformer that can reduce magnetic flux leakage when a voltage magnitude changes. The present invention is a transformer having a primary side to which a three-phase voltage is applied, and a secondary side disposed opposite thereto and outputting by stepping up or down a voltage in accordance with a winding ratio of a coil, wherein the primary side and the secondary side each have three sides. A rectangular iron core for receiving the voltage of two phases among the above voltages is provided, and each iron core has a coil applied with the voltage of the first phase wound n times on the left side and extended and wound n times on the right side, and at the same time the voltage of the second phase The coil to be applied is wound m times on the right side and then extends m times on the left side to balance the loss caused by unbalance when the load conditions are different from each other to reduce the loss of the transformer.
