Abstract

PURPOSE:To attempt to curtail a resin of high cost, simplify the molding work and stabilize the quality of a current transformer by a method wherein the resin is poured only to a lead out part of primary conductor of an inside container and into a small gap between the inside container and a shelter. CONSTITUTION:A resin 9 is poured only to a lead out part of primary conductor of an inside container 18 and into a small gap between the inside container 18 and a shelter 15 made with a thin film insulator. By this way, the quantity of resin 9 to fill up is decreased drastically being able to reduce the price. Besides the permeation of resin 9 into an insulator 13 of a circular part 12 caused at the time of resin injection or hardening is prevented by a shelter 15, and the drying process and the impregnating process of insulating oil become easy owing to a duct between an insulator 13 and the shelter 15. Moreover, as the insulating oil exists on the surface of mold or on the surface of inside container 18 coming in contact with the surface of mold, large cooling effect can be obtained by the insulating oil.
