の過熱点を探知することができる。It is known today to determine the life of a power transformer by the so-called hot spot temperature. (For example, AJ Wakeling, "About Power Transformers," CIGRE SC 12, 198
(Refer to 5 years.) Recently, monitoring of transformers has been performed by temperature sensors disposed at portions of the transformer that are estimated to be hot spots. (Lampe et al., International Conference on Large High-Voltage Electrical Systems, 19
(February 12, 1984) A glass fiber with an optical sensor at the end is installed to make as close a thermal contact as possible with the estimated (and detected by computer simulation) hot spot. However, the estimated hot spot is not necessarily the actual hot spot. This discrepancy is known DT
Can be overcome by the S-system (distributed temperature sensor). That is, if a sensor fiber along which the temperature is measured is provided in the winding of the transformer, the actual hot spot can be detected.

ればならない。Measuring the temperature distribution of the transformer winding or impedance coil not only requires a suitable measurement system (DTS), but also requires that the temperature sensor be properly embedded in the winding. In this case, there is no need to subsequently wind the photoconductor around the winding, but rather integrate the photoconductor directly into the conductor in the form of a combination of photoconductor and conductor, and then Windings must be manufactured. However, because the photoconductor is sensitive to pressure and bending, it must be well protected from mechanical loading and must be constructed to withstand the unavoidable thermal expansion of the conductor during operation.

れぞれの巻線の導体１の内側に備えられてある。FIG. 1c shows that the conductor 1, which is a part of the winding, is bent. The conductor is on a circle of radius r S (winding radius). The winding radius r S is measured from the center of the winding to the center plane M of the band-shaped conductor 1. A vertical groove 3 is 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１に対して余剰長さを備えてい

波行線を描いて配置されている。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と光導電体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。縦みぞ３の寸法は極め
て重要な意味を持つ。The photoconductor 2 is loosely arranged in the vertical groove 3. Furthermore, the photoconductor 2 has an extra length with respect to the conductor 1. That is, the photoconductors are arranged in the vertical grooves 3 not in a straight line but in wavy lines. Or in other words,
A complete turn of the winding is cut, and the conductor 1 and the photoconductor 2 are cut.
Is that the photoconductor 2 is longer than the conductor 1 by the surplus length L. The size of the vertical groove 3 has a very important meaning.
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。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 first important point is that the vertical groove is the center plane M of the conductor 1.
Are arranged asymmetrically with respect to That is, the vertical grooves are not deep enough to basically reach the center plane M. The purpose of this structure is to keep the axis A of the photoconductor 2 in the vertical groove 3 at a minimum distance α to the center 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 vertical groove 3 is such that the distance α is just half the diameter of the photoconductor 2 towards the central plane M.

ければならない。The second important point is that the vertical grooves 3 extend linearly.
Is that the excess length of the photoconductor 2 has a lateral dimension that can be absorbed by forming the photoconductor in the form of a wavy line. Therefore, it is necessary that the width is 2 to 5 times the diameter of the photoconductor 2. Similarly, the depth of the vertical grooves will need to be one to two times the diameter of the photoconductor 2. In any case, it must be ensured that the photoconductor 2 can be freely displaced in the longitudinal groove 3 and not be clamped in any way (for example by an insulator).
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１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１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 photoconductor 2 is prevented from being detached from the vertical groove 3 by the paper insulator 4. FIG. Even when the photoconductor 2 is not in surface contact with the conductor 1, the photoconductor 2 is surrounded by the conductor 1 from three sides, or the entire winding is immersed in the oil bath. For this reason, thermal contact is maintained between both conductors 1 and 2.
導体１が大きく熱膨張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 loading when the conductor 1 undergoes significant thermal expansion can be determined as follows.
表Ｉは温度が０゜から300℃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。Table I shows the expansion rates of typical materials as the temperature increases from 0 ° to 300 ° C.
表I:石英ガラス、銅及びアルミニウムの０゜〜300℃
まで温度上昇した場合の熱膨張率 石英ガラス 0.19×10-3 銅 5.2 ×10-3 アルミニウム 7.7 ×10-3 この表から、相対余剰長さΔL/Lは少なくとも約0.00
1、好適には約0.005とすべきことがわかる。Table I: 0 ° to 300 ° C for quartz glass, copper and aluminum
Thermal expansion coefficient when temperature rises to above Quartz glass 0.19 × 10 -3 Copper 5.2 × 10 -3 Aluminum 7.7 × 10 -3 From this table, the relative excess length ΔL / L is at least about 0.00
It can be seen that 1, preferably about 0.005.
余剰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、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。Since the excess length causes the photoconductor 2 to bend, if the excess length becomes excessive, the local bending (micro-macro bending) of the photoconductor 2 becomes so large that attenuation due to the bending occurs, that is, the light beam is cut off. The stronger it gets.
実験では、本発明に基づく巻線は厚さ2.5mm、幅12mm

た縦みぞ３は幅、深さとも1.2mmとされた。縦みぞ内に

った。銅バンドは紙絶縁体で巻つけられた。巻線全体が
油浴に浸漬された。In experiments, windings according to the present invention were 2.5 mm thick and 12 mm wide
Manufactured from copper bands. The vertical groove 3 provided inside the copper band had a width and a depth of 1.2 mm. The glass fiber loosely arranged in the vertical groove had a diameter of about 0.6 mm. The copper band was wrapped with paper insulation. The entire 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

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 obvious thing was that the temperature distribution periodically rises and falls with the winding. Further, it has been found that the average value of the temperature distribution is higher for windings above the oil bath than for windings below.
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 according to the present invention will be described.
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。This basically has two stages. In the first stage, the combination of conductors (conductor plus photoconductor) is wrapped around the auxiliary drum, and in the second stage, the combination of conductors is rewound from the auxiliary drum.
第2a図は第１の段階を示したものである。導電体１に
は既に本発明に基づく縦みぞが設けてあるものとする。
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。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。FIG. 2a shows the first stage. It is assumed that the conductor 1 is already provided with a vertical groove according to the present invention.
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 the paper insulator 4. Therefore, the combination of conductors is wound around the auxiliary drum such that the vertical grooves 3 are on the outside.
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 outside the center plane M by the distance d, the photoconductor is located on an arc slightly larger than the 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。
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。FIG. 2a shows the second stage. The combination of conductors is wound from the auxiliary drum 5 and wound around the winding 6.
At that time, the winding direction must be reversed. That is, the winding 6 must be wound so that the vertical groove 3 of the conductor 1 located outside on the auxiliary drum 5 comes inside the winding 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
に収納されている。補助ドラムから巻き戻す際に最初の
余剰長さが生じ、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 stored linearly in the vertical groove 3. The first surplus length occurs when rewinding from the auxiliary drum, and the second surplus length occurs when winding around. This surplus length occurs only in the asymmetric vertical groove 3, that is, 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、本発明に基づく方法によ
り次の相対余剰長さΔL/Lが生ずる。Assuming that the center plane M of the conductor 1 is a neutral plane when the conductor is bent, the method according to the present invention produces the following relative excess length ΔL / L.
相対余剰長さΔL/Lは導電体１の長さＬを基準にして
光伝導体と導電体１との間の長さの差ΔＬによって規定
される。距離αは第1b図との関連で定められたものであ
る。rTはドラム半径、rSは巻わくの半径である。 The relative excess length ΔL / L is defined by the length difference ΔL between the photoconductor and the conductor 1 based on the length L of the conductor 1. The distance α is determined in relation to FIG. 1b. r T is the radius of the drum, and r S is the radius of the winding.
前述の実験ではrT＝0.3m、rS＝0.2mであった。距離α
＝0.6mmとすると、相対余剰長さ となる。ミクロないしマクロ曲折による著しい付加減衰
を生起せずに0.02までの相対余剰長さを収容するには、
縦みぞ３の幅は1.2mmで十分である。In the above experiment, r T = 0.3 m and r S = 0.2 m. Distance α
= 0.6mm, relative excess length Becomes To accommodate relative excess lengths of up to 0.02 without significant additional attenuation due to micro or macro bends,
A width of the vertical groove 3 of 1.2 mm is sufficient.
本発明に基づく方法では、導電体１を巻わくに巻取る
前に、先ず補助ドラムに完全に巻付ける必要はないとい
うことが理解されよう。基本的に、適当なわん曲半径を
有する方向転換ドラムを通過させるだけで十分である。
しかしいずれにせよ、方向転換ドラムを通過後、所望の
最初の余剰長さが生じ、かつ維持されるように留意しな
ければならない。It will be appreciated that in the method according to the invention, it is not necessary to first completely wind the auxiliary drum before winding up the conductor 1. Basically, it suffices to pass through a turning drum having a suitable radius of curvature.
However, in any event, care must be taken that after passing through the diverting drum, the desired initial excess length occurs and is maintained.
補足的な余剰長さは縦みぞ内の光伝導体２の曲折を強
めることによっても得られる。これは、光伝導体１を縦
みぞ内に挿入する前に取り付け、巻線の稼働時に取りは
ずす補助節によって実施できる。An additional surplus length can also be obtained by increasing the bending of the photoconductor 2 in the vertical groove. This can be done by means of an auxiliary section which is installed before the photoconductor 1 is inserted into the longitudinal groove and which is removed when the winding is running.
例えば、縦みぞ３内にろう製の節を取り付け、その間
で光伝導体２が蛇行するようにすることができる。巻線
の巻取り後に前記ろう製の節は熱破壊され、又は油浴内
の浸漬油内で溶解される。For example, a braided node may be mounted in the vertical groove 3 between which the photoconductor 2 meanders. After winding, the brazed nodes are thermally broken or melted in immersion oil in an oil bath.
