IRON CORE GROUNDING STRUCTURE OF TRANSFORMER AND IRON CORE GROUNDING METHOD

摘要

PROBLEM TO BE SOLVED: To make it possible to easily ground the wound iron core without requiring complicated grounding work.SOLUTION: A transformer (1) includes: an iron core (10) around which an amorphous alloy thin band is wound; a winding (20) into which the iron core (10) is inserted; a frame (30) accommodating a part of the iron core (10); and a ground plate (50) which is fixed to the frame (30) and grounds the iron core (10). The ground plate (50) is inserted between the layers of the amorphous alloy thin bands constituting the iron core (10).SELECTED DRAWING: Figure 1
