Abstract

DC60 (07/06/53) The method for manufacturing transformers covers the following steps: 1) Inserting the wound transformer coil unit into the E-core; 2) Securing the I-core by welding or fitting the wound transformer coil unit to the E-core; 3) Attaching a mounting base to the I-core for securing the transformer to other tools; and 4) Laying insulating paper around the sides of the transformer coil unit to insulate the area between the transformer coil unit and the E-core. This insulating paper is made of mica, which resists corona generation, preventing high temperatures under high voltage. The easy peeling during mica bonding and proper placement in the intermediate layer with nomex, which is relatively easily damaged by corona charge, and the peel resistance that occurs during nomax bonding, create a bond with multiple surface sides of the mica by adhesive. The method for manufacturing transformers encompasses the steps of 1) packing the wound transformer coil unit onto the E-core; 2) securing the I-core with the assembled wound transformer coil unit to the E-core by welding or fitting; 3) attaching a mounting base for the transformer to the I-core; and 4) applying insulating paper around the sides of the transformer coil unit to provide insulation between the core and the I-core. The transformer coil unit, with its E-core paper insulation, is covered with mica, which resists corona generation, causing high temperatures under high voltages. Simple peeling during mica bonding and proper placement in an intermediate layer with nomex, which is relatively susceptible to corona damage and resists peeling during nomax bonding, create a strong bond with multiple surface aspects of the mica via an adhesive.

1. The method for the manufacture of transformers consists of the steps of: filling, inserting a wound transformer coil unit to an E-core, fixing the core-I ( E-Core) on the assembly of the wound transformer coil unit to the E-core by welding or wearing. The attachment of the cradle for the attachment of such an electric brush pot to another apparatus to the I-core, and to coat insulating paper around multiple side surfaces of the transformer coil unit. In order to insulate between that transformer coil unit and the E-core, many sides in the case of the insulating paper include mica, which resist high temperature corona charge. Rise under high voltage It is easily peeled off during mica bonding and is properly placed in the intermediate and nomex layer where the corona charge is relatively prone to damage and peel resistance. During the bonding of the nomax, a bond with the mica lateral surface is formed by the adhesive.
