Amorphous core transformer

摘要

An amorphous core transformer is provided which is capable of effectively suppressing influences, fluctuation, displacement or the like of a coil caused by an electromagnetic mechanical force or the like. In an amorphous core transformer 100 including an amorphous core 101, a plurality of coils 102 in which the amorphous core 101 is inserted and a fixing metal frame 110 that assembles the coils 102 and the amorphous core 101, the inter-coil member 106 is interposed between the neighboring coils 102 and the inter-coil member 106 is positioned and held by a positioning member 107. Thus, it is possible to prevent the coils 102 from being deformed or displaced beyond the inter-coil member 106 and maintain the shape of the coils 102.

主权项

1. An amorphous core transformer comprising:
an amorphous core; a plurality of coils in which the amorphous core is inserted; a fixing metal frame that arranges the coils adjacent to each other and assembles the coils and the amorphous core; a plate-shaped inter-coil member which is interposed between the adjacent coils; and a positioning member which has a plane spreading in a direction in which the plurality of coils are aligned, and which fixes the plurality of coils in an axial direction, wherein the fixing metal frame comprises a plate-like member which is arranged so as to be along an outer circumference surface of a coil among the plurality of coils that is arranged on an outer circumference side, and which has a plane spreading in a direction substantially parallel to the plate-shaped inter-coil member, the positioning member is formed with a notch-like positioning groove, and the inter-coil member is fixed so as not to move in the direction in which the plurality of coils are aligned by engaging with the notch-like positioning groove, the positioning member is spread in a direction substantially perpendicular to the fixing metal frame and is fixed in a state directly contacting the fixing metal frame, and the positioning member is spread in a direction substantially perpendicular to a plurality of the inter-coil members, and the positioning member and the plurality of the inter-coil members are fixed to each other in concavo-convex engagement.
