    摘要: A transformer, including a first coil and a second coil. The first coil is magnetically coupled to the second coil. At least one of the first coil and the second coil includes a plurality of sub-coils, and the plurality of sub-coils include a first sub-coil and a second sub-coil. A first magnetic field formed by the first sub-coil passes through a layout plane of the transformer in a first manner, and a second magnetic field formed by the second sub-coil passes through the layout plane in a second manner. The first manner includes passing in from a first surface of the layout plane and passing out from a second surface of the layout plane, and the second manner includes passing in from the second surface and passing out from the first surface.

    摘要: A transformer comprises a winding structure which forms a primary side coil, a secondary side coil and first and second wires wound into the coil structure of the transformer. The first wire and second wire define a capacitance between them. The first wire is coupled to a cold point in the primary side and the second wire is coupled to a cold point in the secondary side, thereby this capacitance forming a Y-capacitor between the primary and the secondary sides. This capacitance may for example be used for EMI suppression.

    摘要: The present invention provides a capacitive voltage transformer, including: a capacitive voltage-dividing component and an electromagnetic unit. The capacitive voltage-dividing component comprises: one or more levels of stacks, and each stack is a coupling capacitor. The coupling capacitor includes: an upper cover plate, a lower cover plate, an insulating sleeve, a capacitor core, squirrel cage electrodes, volume matching devices, a high voltage lead, and a low voltage lead. The lowermost coupling capacitor is provided with a medium voltage lead and a lead terminal. The low voltage lead of the lowermost coupling capacitor is led out through a low-voltage leading-out tube arranged in the lead terminal, and the medium voltage lead of the lowermost coupling capacitor is led out through a medium-voltage leading-out post arranged in the lead terminal. The medium-voltage leading-out post passes through and out of the low-voltage leading-out tube and is arranged coaxially with the low-voltage leading-out tube.
