<p><P>PROBLEM TO BE SOLVED: To reduce the size of a transformer by reducing the size of a tap changeover section. <P>SOLUTION: A transformer comprises: a plurality of tap terminals 15a-c provided to a tap winding 5; common terminals 17 provided to the side of the tap terminals 15a-c, to which any one of the tap terminals is connected with a tap changeover connection terminal 16; a first common terminal surface 20c; a second common terminal surface 20b extending downward from the tip of the first common terminal surface; and a third common terminal surface 20a extending from the lower end of the second common terminal surface, in parallel with the first common terminal surface 20c. Each of the tap terminals 15a-c has a vertical section shifted to the end of the tap winding 5 in the winding radial direction and drawn out from the same position in the circumferential direction, and has a tap terminal surface horizontally extending in the outer direction of the winding diameter from the tip of the vertical section and formed to be flush with any one of the first to third common terminal surfaces 20a-c. The common terminal surface and the tap terminal surface, which are formed to be flush with each other, are bolt-connected with the tap changeover connection terminal 16 to change over among the taps. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
