Abstract
During the assembly process of an amorphous core transformer, when an offset has arisen between a coil and the amorphous core, and when an offset has arisen between the coil and the core due to a shock resulting from unloading or vibrations during transport, there has been the risk of breakage of an insulating member between an amorphous core and a coil, causing amorphous fragments to be scattered. The object of the present invention is to prevent scattering of amorphous fragments. The amorphous core transformer, which results from assembling a coil and an amorphous core having a joint section, is characterized by folding an insulating member having a rectangular cylinder and flanges, inserting the folded insulating member into the hole of the coil, expanding the cylinder and the flanges of the insulating member, disconnecting the joint section of the amorphous core, inserting the open-ended amorphous core into the cylinder of the insulating member placed within the coil, lapping the disconnected joint section of the amorphous core, and covering/wrapping yokes of the amorphous core with the flanges of the insulating member.
