METHOD OF MANUFACTURING AMORPHOUS CORE TRANSFORMER AND AMORPHOUS CORE TRANSFORMER

摘要

PROBLEM TO BE SOLVED: To provide an environment-friendly method of manufacturing an amorphous core transformer by which energy consumption and the manufacturing cost can be reduced by eliminating overlapping processes and reducing the number of facilities used for excitation and annealing, and to provide an amorphous core transformer.;SOLUTION: The amorphous core transformer is provided with an amorphous wound core 1 around which a plurality of thin belts of amorphous magnetic material is wound and a coil 2 into which the core 1 is inserted. The core 1 is provided with a heat-resistant insulating material 5 in a lapped part and the coil 2 has a heat-resistant insulating material. In order to prevent the amorphous wound core 1 from becoming stressed by hanging the core 1 in the air, the end face of the coil 2 is supported by a rest made of a flame retardant material.;COPYRIGHT: (C)2004,JPO
