Abstract
In a first secondary-side bobbin 50A, a roll surface of a winding section SA2 is located outward in radial direction with respect to a roll surface of a winding section SA1 in the vicinity of a groove 55A, while a roll surface of a winding section SA3 is located outward in radial direction with respect to the roll surface of the winding section SA2 in the vicinity of a groove 56A. Furthermore, the two winding sections SA2, SA3 cross each other so that the respective roll surfaces have substantially oval-coin-shaped cross sections and the respective major axis lines on the cross sections of the respective roll surfaces cross each other when viewed from the Y-axis direction.
Claims12
A high-voltage transformer comprising:
- an insulating secondary-side bobbin made up of a roll, around which a secondary winding electromagnetically coupled with a primary winding is wound, divided into a plurality of winding sections lined up in a direction in which a central axis of the roll extends by a plurality of partition flanges arranged separated from one another in said direction,
- wherein grooves are formed in said partition flanges for passing said secondary winding from a low-voltage side winding section adjacent to said partition flange to a high-voltage side winding section,
- wherein the roll surface of said high-voltage side winding section is constructed so as to be located outward in radial direction with respect to the roll surface of said low-voltage side winding section in the vicinity of said groove, and
- wherein at least one set of two winding sections out of said plurality of winding sections provided for said secondary-side bobbin are constructed in such a way that each roll surface within a surface crossing said central axis at right angles has a flat cross section and the respective axis lines corresponding to a major axis in the cross section of said each roll surface cross each other when viewed from a direction in which said central axis extends.
