<p><P>PROBLEM TO BE SOLVED: To provide a high-voltage generator which is not made large-sized to be easily stored in a limited space in an electrostatic coating machine, prevents breaking of a winding due to unbalance between heat generation and heat dissipation and sparking due to a drop in withstand voltage to improve durability, and is also improved in efficiency of output electric power against input electric power to lighten the load on a controller. <P>SOLUTION: A step-up transformer 2 includes a core 7, a primary winding 8 wound around the core 7, a bobbin 10 covering an outer periphery of the primary winding 8, a secondary winding 11 laminated and wound around an outer periphery of the bobbin 10, and annular insulating layers 9 and 12 disposed between the outer periphery of the primary winding 8 and a layer of the secondary wiring 11. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
