<p>PURPOSE:To use the primary side insulating layer of a current transformer in common to the high voltage side winding of an insulating transformer so as to enable miniaturization by attaching the iron core and the high voltage side winding of the insulating transformer along the primary winding of the current transformer. CONSTITUTION:An iron core 11 for insulating transformer around which high voltage side winding 10 is applied is provided along the primary winding 1 of a current transformer, and a high voltage side terminal 12 is connected to the high voltage side winding 10. Next, the primary winding 1 of the current transformer and the iron core 11 for insulating transformer around which the high voltage side windings 10 is applied are made in a body and an insulating layer 3 is provided, and thereon the lower voltage side winding 14 of the insulating transformer is provided, and a low voltage side terminal 15 is connected. Furthermore, interlinked with the insulating transformer, an iron core 4 for the current transformer and a secondary winding 16 for the current transformer which was wound around its whole circumference are provided. The secondary winding 16 of the current transformer and the high voltage side winding 10 and the low voltage side winding 14 of the insulating transformer are made in the so-called Rogowskii coil-shaped windings.</p> |
