Description
【発明の詳細な説明】 [技術分野] 本発明は電カケーブル用導体の製造方法に係わる。[Detailed description of the invention] [Technical field] The present invention relates to a method of manufacturing a conductor for an electric power cable.
[背景技術]
従来、電カケーブル用導体で、例えば100〇−以上の
大導体になると、あらかじめ、梯形圧縮してプレフォー
ムを付けた分割セグメントを集合して円形導体に仕上げ
た集合導体が使用されてきた。[Background technology] Conventionally, for conductors for electric power cables, when the conductor is large, for example, 1000 mm or more, an assembled conductor is used, which is made by assembling segmented segments that have been compressed into trapezoids and preformed to form a circular conductor. It has been.

製造方法を特願昭58−75823号で提案した。With such a configuration, existing collecting machines can usually only collect up to 6 pieces due to capacity and number of bobbins. A circular conductor in which divided stranded wire segments are assembled while insulating each segment with segment insulating paper can suppress the increase in AC resistance due to the skin effect compared to a non-divided circular conductor, and the larger the number of divisions, the greater the suppression effect. However, as mentioned above, in order to obtain a low-loss conductor with even less skin effect, the present inventor planned to construct a conductor for power cables consisting of a larger number of divided segments, and To match the storage capacity, a plurality of primary segments are insulated and twisted together in advance to create secondary segments, and these multiple secondary segments are transferred to the collection machine within the limits of the storage capacity of the collection machine. A method of manufacturing conductors for power cables that is supplied and assembled was proposed in Japanese Patent Application No. 75823/1983.
ところが、2次セグメントを作るためには、2台の1次
セグメント撚合せ機とそのタンデム集合機を必要とする
か、あらかじめ撚合せた1次セグメントを2條ばらばら
に集合用サプライボビンに巻いておき、1次セグメント
2條のみを集合機にかけて、1條の2次セグメントを作
る必要もあった。However, in order to make secondary segments, two primary segment twisting machines and their tandem assembly machines are required, or the primary segments that have been twisted in advance are wound in two pieces on a collection supply bobbin. It was also necessary to create a secondary segment of 1 stage by applying only 2 stages of the primary segment to a gathering machine.
しかしこれでは、必要な数の2次セグメントを製造する
のに、多くの設備と多大の時間を必要とし、極めて非能
率的であった。However, this method requires a large amount of equipment and a large amount of time to manufacture the necessary number of secondary segments, and is extremely inefficient.

以」二説明したように、従来は大きな分割数を有する電
カケーブル用導体を製造するためには、1次セグメント

な手段によらなければならなかった。[From the Disclosure of the Invention] As explained in 2, conventionally, in order to manufacture conductors for power cables having a large number of divisions, the process of assembling primary segments to create secondary segments was an uneconomical process. had to be done by some means.

るものである。Therefore, in the present invention, primary segments are manufactured continuously using 11 twisting machines, and as a winding bobbin for winding the primary segments, one collecting machine supply bobbin is divided by a separator, and divided into divided sections. Each primary segment is wound independently, and this is passed through an existing assembly machine that hooks onto multiple supply bobbins, and two primary segments from each supply bobbin are passed through a pre-die and assembled into a secondary segment, and the number of segment divisions is determined. If is an odd number, match the unassembled secondary segments and the primary segments that have already been twisted to the same size, and then use the assembly die to separate the assembled secondary segments together or between the secondary segments and the primary segments. The aim is to obtain an assembled conductor that is a circular conductor.

Accordingly, the supply bobbin 1 is divided into sections 4 and 6 in the figure.

セグメントを巻きとっておく。A large number of copper strands are twisted in advance using a single ordinary twisting machine, and then compression molded into a preform into a predetermined shape through a forming die and a forming roll to obtain the primary segment 4. This primary segment 4 is wound in order, for example, around the section α of the supply bobbin, and when it has been wound for a predetermined length, it is cut and wound around the section name. While the primary segment 4 is being wound around this compartment, another supply bobbin L is prepared, and at the same time as the winding of the 6 compartments is completed, it is sequentially twisted onto the newly prepared supply bobbin 1. Wind the primary segment. If the number of segment divisions is odd, use one of the supply bobbins with a separator.
If the supply bobbin is a conventional supply bobbin with only a section or without a separator, a primary segment having the same size as a secondary segment after collecting two primary segments is wound up as is.

ンlごとにプリダイス5を対応させる。The supply bobbin 1 in which the primary segments of a predetermined length are wound around each of the small centers of the compartments in this manner is hung on an ordinary collecting machine of the supply bobbin rotating type shown in FIG. For example, a separator is provided on each of six collection machine supply bobbins 1, and 12 primary segments 4 are prepared, each of which is independently wound. However, the figure only shows two supply bobbins. 5 is a pre-dice for assembling primary segments 4 to create secondary segments. A pre-die 5 is associated with each supply bobbin l.

グメントを加えて集合する。The secondary segments 6 collected by each pre-die 5 are collected together by a collection die 7 and wound around a collection take-up bobbin 9. Note that if the number of segment divisions is an odd number, the above-mentioned primary segments are added and assembled at the stage of secondary segment assembly.

Rotates on the rotating support frame and comes out from the pre-dice 5 2
Twisting is applied to the next segment 6 according to the preform attached to the primary segment, and as the entire rotating support frame revolves, all the bobbins revolve, and the fixed collecting die 7
The collected conductors 8 that come out of the wafer are twisted and assembled.

紙をラップ巻きしてセグメント間の絶縁を形成する。In this case, at the stage of assembling the primary segments 4 to the secondary segments 6, insulating paper may be applied vertically to one segment to form insulation between the segments, or from the secondary segments 6 this may be connected to the assembled conductor. At the stage of assembling the segments 8, segment insulating paper is wrapped around every other secondary segment 6 due to assembly to form insulation between the segments.
このような工程により、本例の場合、12分割セグメン
トによる円形状の集合導体を得ることができる。Through these steps, in this example, a circular collective conductor made up of 12 segments can be obtained.
