【考案の詳細な説明】 本考案は変圧器巻線に関し、特に巻鉄心に装着された巻
線間の絶縁構造に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to transformer windings, and particularly to an insulation structure between windings attached to a wound core.

従来の巻鉄心変圧器は鉄心３に装着された巻線１Ａと１

巻線ＩＡと１Ｂとの間にプレスボード製のバーリヤ２が
挿入されている。A conventional wound core transformer has windings 1A and 1 attached to core 3.
In order to maintain insulation between windings IA and 1B, a pressboard barrier 2 is inserted between windings IA and 1B as shown in FIGS. 1a and 1b.

また、これらのバーリヤ２は運転中の脱落を防止するた

線１Ａと１Ｂの対向面に嵌め込んで固設されている。Further, in order to prevent these barriers 2 from falling off during operation, both upper and lower ends are bent to form a U-shaped cross section, and the barriers 2 are fitted and fixed onto opposing surfaces of the windings 1A and 1B.

尚図中、４は外周絶縁紙である。ところが、このような
従来の巻鉄心変圧器においては、バーリヤ２を挿入する

。SUMMARY OF THE INVENTION An object of the present invention is to provide a transformer winding having an insulating structure that can eliminate the barrier insertion work which is a drawback of the prior art and also ensure insulation between the windings.

以下に本考案の一実施例を図面に基づき詳細に説明する
。An embodiment of the present invention will be described in detail below with reference to the drawings.

ープ６により縛着された構造である。In the transformer winding of the present invention, as shown in FIGS. 2 and 3, one end of the outer insulating paper 5 is wound around the outer periphery of each of the windings IA and IB, which are wound around a bobbin and arranged side by side. The structure is such that an outer insulating paper 5 is folded in a zigzag pattern a plurality of times on opposing surfaces of the windings 1A and 1B while the windings 1A and 1B are inserted into the windings 3, respectively, and the outer periphery of the insulating paper 5 is bound with an insulating tape 6.

この場合、対向面での外周絶縁紙５の折畳み回数は使用
する外周絶縁紙５の厚さや、変圧器の絶縁等級により適
宜決定される。In this case, the number of times the outer insulating paper 5 is folded on the opposing surface is appropriately determined depending on the thickness of the outer insulating paper 5 used and the insulation grade of the transformer.

また外周絶縁紙５を折畳むには第４図ａ−ｃに示す如く
折畳むとよい。Further, in order to fold the outer circumference insulating paper 5, it is preferable to fold it as shown in FIGS. 4a to 4c.

第４図ａおよびｂは、外周絶縁紙５を巻線１Ａまたは１
Ｂに巻回してその対向面で折畳んで設けた場合を示し、
第４図ａはその折曲げ端７が外側に位置し、第４図すは

。4a and b, the outer insulating paper 5 is wound around the wire 1A or 1.
It shows the case where it is wound around B and folded on the opposite surface,
In FIG. 4a, the bent end 7 is located on the outside, and in FIG. 4, the bent end 7 is located inside.

また第４図Ｃは対向面で外周絶縁紙５を数回折畳んでか
ら巻線の外周に巻回したものであ。Further, in FIG. 4C, the outer insulating paper 5 is folded several times on the opposing surface and then wound around the outer periphery of the winding.

尚５Ａは折畳み個所を示す。Note that 5A indicates the folding point.

このように巻鉄心に装着される巻線１Ａと１Ｂの対向面
で外周絶縁紙５が数回折畳まれた構造であるため、この
折畳まれた個所が従来のバーリヤの役割を果し、従来の
バーリヤの挿入作業は不用となる。Since the outer insulating paper 5 is folded several times on the opposing surfaces of the windings 1A and 1B attached to the wound core, these folded parts function as a conventional barrier, and This eliminates the need to insert a barrier.

その結果作業工数を大幅に縮小できると共に部品点数を
減少することができる。As a result, the number of work steps can be significantly reduced, and the number of parts can also be reduced.
