ることができる。It is known today to determine the service life of power transformers by means of the so-called hot spot temperature. (For example, A. J. Wakeling, ``On Power Transformers, JCIGRE
(See SC 12, 1985) Recently, transformers have been monitored by temperature sensors placed at presumed hot spots within the transformer. (Lampe et al., International Conference on Large High Voltage Electrical Systems, February 12, 1984) A glass fiber with an optical sensor at the end is used to detect the estimated (and detected by computer simulation) hot spots and Installed for good contact. However, the estimated hot point is not necessarily the actual hot point; this discrepancy can be overcome by the known DTS system (Distributed Temperature Sensor). That is, by providing a sensor fiber in the transformer winding along which temperature measurements are taken, the actual hot spot can be detected.

ればならない。Measuring the temperature distribution in a transformer winding or impedance coil not only requires a suitable measurement system (DTS), but also a temperature sensor must be appropriately embedded in the winding. In this case, there is no need to wind the photoconductor around the windings afterwards, but the photoconductor is integrated directly into the conductor in the form of a combination of photoconductor and conductor, and then from this combination. Windings must be manufactured. However, since photoconductors are sensitive to stress and bending, they must be adequately protected from mechanical loads and must be constructed to withstand the inevitable thermal expansion of the conductor during operation.

〔実施例〕
次に本発明の実施例を図面を参照しつつ詳細に説明する
。[Example] Next, an example of the present invention will be described in detail with reference to the drawings.
第１ａ図は、本発明に基づ（巻線の平面図、第１ｂ図は
、横断面図、第１ｃ図は縦断面図である。FIG. 1a is a plan view of the winding according to the invention, FIG. 1b is a cross-sectional view, and FIG. 1c is a longitudinal sectional view.
これら３つの図面の同一部分には同一の符号を付しであ
る。Identical parts in these three drawings are designated by the same reference numerals.
バンド状の導電体１、例えば厚さ約２．５ｆｉ、幅が約
１２ｆｌの銅線から出発する。導電体ｌには縦みぞ３を
設け、この縦みぞ内に光伝導体２、例えばアルシリカフ
ァイバーが装入される。好適な実施例では導電体ｌと縦
みぞ３内の光伝導体２は紙絶縁体４で被覆される。Starting from a band-shaped conductor 1, for example a copper wire approximately 2.5 fi thick and approximately 12 fl wide. The electrical conductor 1 is provided with a longitudinal groove 3 into which a photoconductor 2, for example an arsilica fiber, is inserted. In a preferred embodiment, the electrical conductor 1 and the photoconductor 2 in the longitudinal groove 3 are covered with a paper insulator 4.
第１Ｃ図から、巻線の一部である導電体１は曲っている
ことがわかる。導電体は半径ｒＴ（巻ね（半径）の円上
にある。巻わく半径ｒＴは巻わくの中心からバンド状の
導電体１の中心面Ｍまでを測ったものである。縦みぞ３
はそれぞれの巻線の導体１の内側に備えられである。It can be seen from FIG. 1C that the conductor 1, which is part of the winding, is bent. The conductor lies on a circle with a radius rT (winding (radius). The radius rT of the winding is measured from the center of the winding to the center plane M of the band-shaped conductor 1. Vertical groove 3
are provided inside the conductor 1 of each winding.
光伝導体２は縦みぞ３内にゆるく配置されている。更に
光伝導体２は導電体ｌに対して余剰長さを備えている。The photoconductor 2 is loosely placed within the longitudinal groove 3. Furthermore, the photoconductor 2 has an extra length relative to the conductor l.
すなわち、光伝導体は縦みぞ３に直線的にではなく波行
線を描いて配置されている。That is, the photoconductor is arranged in the longitudinal groove 3 not in a straight line but in a wavy line.
あるいは換言すると、巻線の完全な一巻分を切断して、
導電体１と光伝導体２とを伸ばすと、光伝導体２の方が
導電体１よりも余剰長さＬだけ長いということである。Or in other words, cut a complete turn of the winding,
When the conductor 1 and the photoconductor 2 are stretched, the photoconductor 2 is longer than the conductor 1 by an extra length L.
縦みぞ３の寸法は極めて重要な意味を持つ。The dimensions of the vertical groove 3 are extremely important.
第１の重要なポイントは縦みぞは導電体１の中心面Ｍに
対して非対称に配置されていることである。すなわち、
縦みぞは基本的に中心面Ｍに到達するほど深くはない。The first important point is that the longitudinal grooves are arranged asymmetrically with respect to the central plane M of the conductor 1. That is,
The vertical groove is basically not deep enough to reach the central plane M.
この構造の目的は縦みぞ３内の光伝導体２の軸Ａが中心
面Ｍに対して最小距離αを保つことである。The purpose of this construction is to keep the axis A of the photoconductor 2 in the longitudinal groove 3 at a minimum distance α to the central plane M.
好適な一実施例では縦みぞ３は、距離αが中心面Ｍに向
かって光伝導体２の直径のちょうど半分になるようにな
っている。In a preferred embodiment, the longitudinal grooves 3 are such that the distance α is exactly half the diameter of the photoconductor 2 towards the central plane M.
第２の重要なポイントは、直線的に延在する縦みぞ３が
、光伝導体２の余剰長さを、光伝導体を波状線の形態に
することによって吸収できる横寸法を有していることで
ある。従ってその横幅が光伝導体２の直径の２倍乃至５
倍であることが必要である。同様に縦みぞの深さは光伝
導体２の直径の１倍乃至２倍であることが必要であろう
ｉいずれにせよ、光伝導体２が縦みぞ３内で自由にずれ
ることができ、かつ何らかのかたちで堅く締めつけられ
る（例えば絶縁体によって）ことがないようにされなけ
ればならない。A second important point is that the linearly extending longitudinal groove 3 has a lateral dimension that allows the excess length of the photoconductor 2 to be absorbed by placing the photoconductor in the form of a wavy line. That's true. Therefore, its width is 2 to 5 times the diameter of the photoconductor 2.
It is necessary to double the amount. Similarly, the depth of the longitudinal groove may need to be between 1 and 2 times the diameter of the photoconductor 2; in any case, the photoconductor 2 can be freely displaced within the longitudinal groove 3; and must not be tightened in any way (e.g. by insulation).
第１ａ図乃至第１Ｃ図の実施例では、紙絶縁体４によっ
て光伝導体２が縦みぞ３から離脱し得ないようにされて
いる。光伝導体２が導電体ｌと表面的に接触していない
場合でも、光伝導体２が導電体１によって三方から囲ま
れているという理由、あるいは巻線の全体が油浴に浸漬
されているという理由で導電体ｌ及び２の両方の間には
熱接触が保たれる。In the embodiment of FIGS. 1a to 1C, the paper insulator 4 prevents the photoconductor 2 from becoming detached from the longitudinal groove 3. In the embodiment of FIGS. Even if the photoconductor 2 is not in superficial contact with the conductor l, the reason is that the photoconductor 2 is surrounded from three sides by the conductor 1, or the entire winding is immersed in an oil bath. Because of this, thermal contact is maintained between both conductors l and 2.
導体１が大きく熱膨脹した際の機械的負荷から光伝導体
を保護するのに必要な相対的余剰長さは、次のように定
めることができる。The relative excess length required to protect the photoconductor from mechanical loads during large thermal expansions of the conductor 1 can be determined as follows.
表目よ温度が０°から３０θ℃まで上昇した場合の代表
的な素材の膨張率を示している。The table shows the expansion coefficient of a typical material when the temperature increases from 0° to 30θ°C.
表に石英ガラス、銅及びアルミニウムの０゜〜３００℃

Coefficient of thermal expansion when the temperature rises to quartz glass
0.19X10-” copper 5.2
Xl0-'aluminum? , 7 Xl
It can be seen that 0-'' should also be about 0.001, preferably about 0.005.
剰余長さによって光伝導体２は曲折するので、余剰長さ
が過度になるとく光伝導体２の局部的わん曲（ミクロ−
マクロ曲折）は、曲折による減衰が生じるほど、すなわ
ち光線がしゃ断されるほど強くなってしまう。The excess length causes the photoconductor 2 to bend, so if the excess length becomes excessive, local curvature (micro-
Macro bending) becomes stronger as attenuation due to bending occurs, that is, as the light beam is blocked.
実験では、本発明に基づく巻線は厚さ２．５ ＊ｍ、幅
１２鶴の銅バンドから製造された。銅バンドの内部に設
けられた縦みぞ３は幅、深さとも１．２ ｍとされた。In experiments, a winding according to the invention was made from a copper band 2.5*m thick and 12 squares wide. The vertical groove 3 provided inside the copper band had a width and depth of 1.2 m.
縦みぞ内にゆる（配設したガラス・ファイバの直径は約
０．６鶴であった。銅バンドは紙絶縁体で巻つけられた
０巻線全体が油浴に浸漬された。The diameter of the glass fiber loosely placed in the vertical groove was approximately 0.6 mm. The copper band was wrapped with paper insulation and the entire 0 winding was immersed in an oil bath.
ＤＴＳ−測定によって銅バンドに沿った実効温度が計測
された。その際第１に明白に判明したことは、巻きと共
に温度分布が周期的に上昇・下降することだった。更に
、温度分布の平均値は油浴の下方にある巻きより上方に
ある巻きの方が上昇するということが判明した。The effective temperature along the copper band was measured by DTS-measurement. The first thing that became clear was that the temperature distribution rose and fell periodically as the winding progressed. Furthermore, it has been found that the average value of the temperature distribution increases more in the upper turns of the oil bath than in the lower turns.
次に本発明に基づく巻線の製造方法を説明する。Next, a method for manufacturing a winding wire according to the present invention will be explained.
これには基本的に２つの段階がある。第１の段階では導
体の組合わせ（導電体＋光伝導体）を補助ドラムに巻付
け、第２の段階では導体の組合わせを補助ドラムから巻
わくへと巻直す。There are basically two stages to this. In the first stage, the conductor combination (conductor+photoconductor) is wound onto the auxiliary drum, and in the second stage, the conductor combination is re-wound from the auxiliary drum onto the hoist.
第２ａ図は第１の段階を示したものである。導電体ｌに
は既に本発明に基づく縦みぞが設けであるものとする。Figure 2a shows the first stage. It is assumed that the conductor l is already provided with a vertical groove according to the invention.
この縦みぞ内に光伝導体２が先ず、ゆるく、すなわち引
張応力なしに挿入される。次に導電体１と光伝導体２に
紙絶縁体４を被覆する。The photoconductor 2 is first inserted loosely, ie without tensile stress, into this longitudinal groove. Next, the conductor 1 and the photoconductor 2 are covered with a paper insulator 4.
そこで導体の組合わせを、縦みぞ３が外側になるように
補助ドラムに巻付ける。The conductor combination is then wound around the auxiliary drum with the vertical groove 3 facing outward.
光伝導体２の軸Ａは中心面Ｍに対して距離ｄだけ更に外
側に位置するので、光伝導体は導電体よりもやや大きな
円弧上に位置する。Since the axis A of the photoconductor 2 is located further outward by a distance d with respect to the central plane M, the photoconductor is located on a slightly larger circular arc than the electrical conductor.
第２ａ図は第２の段階を示している。導体の組合わせは
補助ドラム５から巻取られ、巻わく６に巻付けられる。Figure 2a shows the second stage. The conductor combination is wound from the auxiliary drum 5 and wound onto the hoist 6.
その際、巻き方向は逆にならなければならない。すなわ
ち、巻わく６は、補助ドラム５では外側に位置していた
導電体１の縦みぞ３が、巻わく６では内側にくるように
巻付けられなければならない。In this case, the winding direction must be reversed. That is, the winding frame 6 must be wound in such a way that the vertical groove 3 of the conductor 1, which was located on the outside on the auxiliary drum 5, is on the inside on the winding frame 6.
補助ドラム５上では光伝導体２は縦みぞ３内に直線的に

剰長さが生じ、巻わくに巻付ける際に２番目の余剰長さ
が生ずる。この余剰長さは非対称の縦みぞ３、すなわち
距離αだけで発生する。On the auxiliary drum 5, the photoconductor 2 is accommodated linearly in a longitudinal groove 3. A first surplus length occurs when unwinding from the auxiliary drum, and a second surplus length occurs when winding onto the hoist. This extra length occurs only in the asymmetric longitudinal groove 3, ie in the distance α.
導電体１の中心面Ｍが、前記導電体を曲げた際の中立面
であると言う前提のもとで、本発明に基る。The present invention is based on the premise that the central plane M of the conductor 1 is the neutral plane when the conductor is bent.

ればならない。It will be appreciated that in the method according to the invention it is not necessary to first completely wind the electrical conductor 1 onto the auxiliary drum before winding it onto the hoist. Basically, it is sufficient to pass through a deflection drum with a suitable radius of curvature. In any case, however, care must be taken that the desired initial excess length is created and maintained after passing through the deflection drum.

す補助節によって実施できる。Supplementary extra length can also be obtained by increasing the bending of the photoconductor 2 in the longitudinal groove. This can be accomplished by means of an auxiliary joint that is attached before the photoconductor 1 is inserted into the longitudinal groove and removed during operation of the winding.
