た。However, the above-mentioned transformer A
The winding support device of No. 2 has sufficient mechanical strength to withstand the repulsive force of the winding 5 at the time of assembly and the electromagnetic force generated during energization of the transformer A. When a short-circuit current exceeding a permissible value flows through the winding 5 and a large electromagnetic mechanical force F is generated in the arrow direction shown in FIG. 6, that is, in the axial direction of the winding 5, the winding 5 swings in the arrow direction. In this case, the winding support pieces 6 and 6a for supporting / fixing the winding 5 are not particularly fixed to the bottom surface a of the tightening metal fittings 1 and 1a, and moreover, the tightening metal fittings 1 and 1a are attached to the iron core 2. When arranged above and below the upper and lower yoke portions 3, 3a, the winding support pieces 6, 6a are arranged such that the laminated end faces of the iron core 2 yoke portions 3, 3a are perpendicular to the fastening metal fittings 1, 1a. Since the space d is provided between the frame c and the frame c (only the lower tightening fitting 1a is shown in FIG. 6), the assembling workability is improved. The winding support pieces 6 and 6a have very weak mechanical strength against external force. As a result, when the electromagnetic mechanical force F is generated, the winding support pieces 6 and 6a oscillate in the arrow direction (left and right direction in FIG. 4) shown in FIG. Since the state shown by the solid line in FIG. 6 is inclined as shown by the dotted line, the winding 5 cannot be supported / fixed.
There was a big problem that it was mechanically destroyed.

Since the winding wound around the winding core is supported and fixed in the axial direction by the pair of winding supporting pieces, for example, the electromagnetic mechanical force generated at the time of a short-circuit accident causes the winding through the winding. When it acts on the support piece, the winding support piece can be securely locked and held in the engagement groove of the tightening fitting, so that it does not swing between the tightening fitting and the winding end surface. There is no such thing as tilting or tilting, and it is possible to protect the winding from excessive electromagnetic mechanical force.
