Zigzag Y-type three-phase four-wire transformer with a double winding to remove harmonics of the present invention at the core of a transformer. Fig. 2 shows a zigzag of double windings to remove the harmonics of the present invention. Y-type three-phase four-wire transformer vector circuit diagram. As shown in Fig. 2, R: -220V 60HZ phase 0 degrees, S: -220V 60HZ phase 120 degrees, T: -220V 60HZ phase 240 degrees, N: -0V (ground). Zigzag Y-type 3-phase 4-wire connection with a mid winding: -R, S, T phases are divided into 1 or 2 primary windings in 1 phase and the blue end in R connects to the blue end in S, S The black end of the phase is connected to the black end of T and the red end of R is equally connected to the red end of T. Three phases meet at three points. The zigzag Y-wire that meets at one point reduces harmonics by order, and also protects against lightning strikes by creating a harmonic-free ground, allowing them to meet at three points in a two-wire winding wound around an iron core type three-phase transformer. Not only does harmonics not generate, but because one winding passes all three phases and is connected to the neighboring (other) phase, the harmonics are resisted where they flow away from the power frequency and disappear as circulating currents. Therefore, harmonics can be eliminated. There is a voltage recovery function at zero voltage of the other phase by the rotation of the magnetic field in the iron core type three-phase transformer core.

이상에서 상술한 바와 같이 본 고안에 따른 변압기는 무부하 손실을 줄이고, 고조파에 강하고, 낙뢰와 충격전압으로부터 강한 효과가 있다. 뿐만 아니라 한 상의 전압 0(zero)V시 전압복구 기능까지 있다.비록 본 고안이 상기에서 언급한 바람직한 실시예와 관련하여 설명되어졌지만, 본 고안의 요지와 범위로부터 벗어남이 없이 다른 다양한 수정 및 변형이 가능할 것이다. 따라서, 첨부된 실용신안등록청구의 범위는 본 고안의 진정한 범위내에 속하는 그러한 수정 및 변형을 포함할 것이라고 여겨진다.As described above, the transformer according to the present invention reduces the no-load loss, is resistant to harmonics, and has a strong effect from lightning and impact voltage. In addition, there is a voltage recovery function at zero voltage of one phase. Although the present invention has been described in connection with the above-mentioned preferred embodiment, various other modifications and variations can be made without departing from the spirit and scope of the present invention. This will be possible. Accordingly, the scope of the appended utility model registration claims is intended to include such modifications and variations as fall within the true scope of the present invention.
