<p><P>PROBLEM TO BE SOLVED: To provide an insulated molded coil capable of suppressing the generation of partial discharge and capable of being easily applied to static induction equipment of special high-voltage class. <P>SOLUTION: In a resin molded coil, a plurality of unit coils 2 formed in an annular shape by winding magnet wires 5 are arrayed and connected in series in the axial direction, and a plurality of electrostatic shielding layers 6 having high resistance values are mounted so as to discretely surround a plurality of these unit coils 2. In the resin molded coil, a resin molded layer 4 molding a plurality of these whole electrostatic shielding layer 6 is mounted, and a conductor at a winding-start end 5a positioned inside the unit coils 2 and a conductor at a winding-end end 5b positioned outside the unit coils 2 are connected electrically to the inner peripheries 6A and outer peripheries 6B of the electrostatic shielding layers 6 surrounding the unit coils 2 respectively (connection points 8A and 8B). <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
