PURPOSE:To effectively fill an insulating filler by so disposing to contain a booster transformer in an insulation case that a partition of a secondary side winding bobbin crosses perpendicularly an opening surface of the case. CONSTITUTION:A booster transformer T has partitions 24 for partitioning a bobbin body into a plurality and winding a secondary wide winding on the body in its axial direction on the outer periphery of the body along an axial direction, a secondary side winding bobbin 21 having the secondary side winding wound on the body between the partitions 24, a primary side winding bobbin 20 contained in a state that the primary side winding is wound in the bobbin body of the bobbin 21, and a core 40 for constituting a magnetic circuit in a state for surrounding the interior of the bobbin 20 and the outer periphery of the bobbin 21. The transformer T is so disposed to contain the partitions 24 of the bobbin 21 in an insulation case 10 as to cross perpendicularly to the opening surface of the case 10. Thus, an insulation of high and low voltage sides is effectively provided to reduce in size an apparatus. |
