HIGH-VOLTAGE TRANSFORMER

PROBLEM TO BE SOLVED: To make the insulation distance required between both the uppermost-layer portions of high-voltage winding portions which are adjacent to each other shorter than conventional ones. SOLUTION: The high-voltage winding portions 7 is so divided into first and second winding portions as to constitute it by winding respectively both the winding portions around the outer peripheral surfaces 400 of a cylindrical bobbin 4 and by connecting both the winding portions in series with each other. The first winding portion is so interposed between flanges 41, 43 of the bobbin 4 as to wind its multiple layers in a single winding direction. The second winding portion is so interposed between flanges 42, 43 of the bobbin 4 as to wind its plural layers in the opposite winding direction to the one of the first winding portion. The places of both the uppermost-layer portions of the first and second winding portions are connected with each other electrically via an intermediate tap 3. COPYRIGHT: (C)2005,JPO&NCIPI
