産業上の利用分野
この発明は、電力用の電気機器に使用するリア
クトル線やリツツ線および変圧器用巻線などに関
するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to reactor wires and wires used in electric power equipment, transformer windings, and the like.
従来の技術
従来のリアクトル線などの一例を「第1図」に
示す。Prior Art An example of a conventional reactor wire is shown in Fig. 1.
10は素線で、導体12上にエナメル皮膜14
を設けたものである。 10 is a bare wire, and an enamel film 14 is formed on the conductor 12.
It has been established.
この素線10を複数本、集合撚又は同心撚し、
その集合体の上に共通の絶縁層20(紙又はプラ
スチツクテープ巻き、例えばプラスチツクとし
て、芳香族ポリアミド紙、ポリイミドフイルム、
ポリエステルフイルム、ポリプロピレンフイルム
等が用いられている。)を施している。 A plurality of these strands 10 are twisted collectively or concentrically,
A common insulating layer 20 (paper or plastic tape wrapping, e.g. plastic, aromatic polyamide paper, polyimide film,
Polyester film, polypropylene film, etc. are used. ) is applied.
しかし、このような構成の絶縁電線には次の問
題がある。 However, the insulated wire having such a configuration has the following problems.
(1) 1本1本の導体の上にそれぞれエナメル皮膜
を形成して撚合わせるのであるから、加工費が
大変高くなる。(1) Since an enamel film is formed on each conductor and then twisted together, the processing cost becomes very high.
(2) エナメル皮膜14を施すことによつて渦電流
損を減少させる効果はあるが、エナメル皮膜1
4の厚みは通常40μm程度なので、占積率が大
変悪くなる。(2) Applying the enamel film 14 has the effect of reducing eddy current loss, but the enamel film 1
Since the thickness of No. 4 is usually about 40 μm, the space factor becomes very poor.
(3) 圧縮成形巻線の場合は、エナメル皮膜14を
形成した素線10をより合わせてから圧縮する
のであるから、圧縮するときエナメル皮膜14
がはげたりすることがある。(3) In the case of compression molded winding, the strands 10 on which the enamel film 14 has been formed are twisted together before being compressed, so the enamel film 14 is compressed when compressed.
The skin may become bald.
この欠点を解消する手段として、例えば第1図
の素線10に対応するものとして銅又は銅合金か
らなる帯状導体の表面にエナメル皮膜より薄い銅
酸化物を化成膜として形成することが考えられる
(実開昭55−106670号)。 As a means to overcome this drawback, it is conceivable to form a copper oxide film, which is thinner than the enamel film, on the surface of a strip-shaped conductor made of copper or copper alloy as a chemical coating, corresponding to the wire 10 in FIG. 1, for example. (Utility Model Publication No. 55-106670).
しかし帯状導体の表面に既に銅酸化物が化成膜
として形成された状態で、この帯状導体を撚合わ
せて絶縁電線を製造しようとすれば、撚合せ時の
強い機械的応力で上記銅酸化物の化成膜が剥離し
てしまい、実用に供せない。 However, if an attempt is made to manufacture an insulated wire by twisting the strip conductors with copper oxide already formed as a chemically formed film on the surface of the strip conductor, the copper oxide will be removed due to the strong mechanical stress during the twisting. The chemically formed film peels off, making it unusable.
同様にして通常の丸の銅素線を撚合わせた導体
において各銅素線表面に酸化銅を形成することも
考えられるが(特開昭57−80610号)、上記導体を
四角に圧縮成形するときに、強い圧縮応力によつ
て銅素線表面の酸化銅が剥離してしまい、酸化銅
を形成してもその実効が図れない。 Similarly, it is possible to form copper oxide on the surface of each copper strand in a conductor made by twisting ordinary round copper strands (Japanese Patent Application Laid-open No. 57-80610), but it is also possible to compression mold the above conductor into a square shape. Sometimes, strong compressive stress causes the copper oxide on the surface of the copper wire to peel off, and even if copper oxide is formed, it is not effective.

なわち同一断面積、同一長さの銅素線の場合、断

がよくなる。ここで上記事実は例えば、
電流をIそのときの磁界をH、周辺長をlとす
れば、
I=φlHdtによつて
lは四角状の方が円周より大きいことから明白
である。 In addition, in the case of copper wires manufactured using the same amount of copper, that is, copper wires with the same cross-sectional area and the same length, a square cross-sectional shape will allow for flow of alternating current more easily than a circular cross-sectional shape. The amount of current is large, and the space factor is naturally improved. Here, the above fact is clear from the fact that, for example, if the current is I, the magnetic field at that time is H, and the peripheral length is l, I = φ l Hdt, and l is larger in the square shape than in the circumference.

る。Problems to be Solved by the Invention The present invention has been made to solve the above-mentioned problems, and its feature is that the copper oxide film on the surface of the copper wire does not peel off at all, that is, it can be manufactured as an insulated wire. Furthermore, this wire is subjected to strong bending stress because it is formed into a coil shape as a reactor wire or transformer winding wire, and the current capacity is increased by making it square in cross section compared to a round wire. The objective is to increase the space factor and also improve the space factor.

実施例 第2図に本発明の絶縁電線の実施例を示す。Example FIG. 2 shows an embodiment of the insulated wire of the present invention.
12aは銅素線又は銅合成素線(以下銅素線と
いう)である。 12a is a copper wire or a copper composite wire (hereinafter referred to as copper wire).
銅素線12aは断面四角状をなし、その表面に
酸化銅皮膜16が形成されている。 The copper wire 12a has a square cross section and has a copper oxide film 16 formed on its surface.
この銅素線12aは通常の丸の銅素線(0.08〜
3.2mmφ)を四角状に圧縮成形したものである。 This copper wire 12a is a normal round copper wire (0.08~
3.2mmφ) compression molded into a square shape.
この銅素線12aがm×n本(m、nは自然
数、図では4×5本)撚合わされて平角線をなす
絶縁電線が形成されている。すなわち一辺がm
本、他辺がn本の四角形状の平角線をなす。 These copper wires 12a are twisted together in m×n pieces (m and n are natural numbers, 4×5 pieces in the figure) to form an insulated wire that is a rectangular wire. In other words, one side is m
A book forms a rectangular rectangular line with n other sides.
この場合銅素線12a同士は面接触となつてい
て、その面圧は(1Kg/cm2〜70Kg/cm2)程度であ
る。 In this case, the copper wires 12a are in surface contact with each other, and the surface pressure is about (1 Kg/cm 2 to 70 Kg/cm 2 ).
20は通常の絶縁層であつて平角線上に被覆さ
れている。 20 is a normal insulating layer which is coated on the rectangular wire.
通常はトランスのコイル等に使用されるために
コイル状に成形される。 It is usually formed into a coil shape for use in transformer coils, etc.
ここで銅素線12a上の酸化銅皮膜16は厚さ
が0.2〜3μm程度であり、又体積抵抗率が105Ωcm
程度である。 Here, the copper oxide film 16 on the copper wire 12a has a thickness of about 0.2 to 3 μm, and a volume resistivity of 10 5 Ωcm.
That's about it.
したがつて導体サイズが小さいため渦電流損の
低減効果は十分持つている。平角線の断面形状は
コイル状に成形することから、正方形ではなく長
方形が望ましい。 Therefore, since the conductor size is small, it has a sufficient effect of reducing eddy current loss. Since the cross-sectional shape of the flat wire is formed into a coil shape, it is desirable to have a rectangular cross-sectional shape rather than a square.
したがつて銅素線12aの断面形状も長方形と
なる。 Therefore, the cross-sectional shape of the copper wire 12a is also rectangular.
本発明の実施例では一辺が4本、他辺が5本で
あつたが、この数に限定されるものではない。し
たがつて一辺が隅数、他辺が奇数、二辺とも偶
数、奇数、適宜選定すればよい。 In the embodiment of the present invention, there were four wires on one side and five wires on the other side, but the number is not limited to these. Therefore, one side may have the number of corners, the other side may have an odd number, or both sides may have an even number or an odd number, which may be selected as appropriate.
要するにコイル巻に適した平角線の形状であれ
ばよい。 In short, any rectangular wire shape suitable for coil winding may be used.
次に上記絶縁電線の製造方法を述べる。 Next, a method for manufacturing the above insulated wire will be described.
第3図に示すごとく、通常の丸の銅素線13を
m×n本円形に撚合わせ、(図では4×5=20
本)、集合体15を形成する。 As shown in Figure 3, ordinary round copper wires 13 are twisted into a circular shape of m x n (4
book), forming an aggregate 15.
次にこの集合体15を圧縮成形機(図示せず)
で四角形に圧縮成形する。 Next, this assembly 15 is molded using a compression molding machine (not shown).
Compression mold into a rectangle.
すると、一辺がm本、他方がn本の平角線が形
成される。 Then, a rectangular wire with m wires on one side and n wires on the other side is formed.
このとき円形の集合体15から平角線となるの
で占積率が5〜30%向上する。 At this time, since the circular aggregate 15 becomes a rectangular wire, the space factor improves by 5 to 30%.
次に上記平角線をきれいに洗浄したのち、例え
ば亜塩素酸ナトリウムとカセイソーダの各5%水
溶液(90〜100℃)などの酸化処理液の中に浸せ
きする。 Next, the rectangular wire is thoroughly cleaned and then immersed in an oxidizing solution such as a 5% aqueous solution of sodium chlorite and caustic soda (90 to 100°C).
すると、各銅素線12aの表面に酸化銅皮膜1
6が形成される。 Then, a copper oxide film 1 is formed on the surface of each copper wire 12a.
6 is formed.
浸せきで時間によつて酸化銅皮膜16の厚みが
変わる。 The thickness of the copper oxide film 16 changes depending on the time during dipping.
厚み、体積抵抗率は上述した程度のものとな
る。 The thickness and volume resistivity are as described above.
なお、圧縮成形したより線の集合体は、銅素線
12aのすき間が大変狭くなつていて、しかも面
圧が1.0〜70Kg/cm2なので、内部まで酸化処理液
が浸透しにくい。 In addition, in the compression-molded stranded wire assembly, the gaps between the copper wires 12a are very narrow, and the surface pressure is 1.0 to 70 kg/cm 2 , so that the oxidation treatment liquid is difficult to penetrate into the inside.
そこで既に発表されているように、平角線を
100℃以上に予熱してから酸化処理液に浸せきす
る(特開昭57−57414)とか、あるいは酸化処理
液中の平角線に超音波を照射する(特開昭56−
73809)等の方法を併用する。 Therefore, as already announced, the flat wire
Preheating the wire to 100℃ or higher and then immersing it in an oxidation treatment solution (Japanese Patent Laid-Open No. 57-57414), or irradiating the rectangular wire in the oxidation treatment solution with ultrasonic waves (Japanese Patent Laid-Open No. 56-1999)
73809) and other methods.
この後通常の手段でリアクトル線、トランスの
巻線等の使用に供するため円形コイル状に成形さ
れる。 Thereafter, it is formed into a circular coil shape by conventional means for use as a reactor wire, transformer winding wire, etc.
このとき曲げ加工による強い曲げ応力が働く
が、銅素線12a同士が面接触であるので、銅素
線12aの表面の酸化銅皮膜は摩擦による剥離が
ない。 At this time, strong bending stress is applied due to the bending process, but since the copper wires 12a are in surface contact with each other, the copper oxide film on the surface of the copper wires 12a does not peel off due to friction.
これが例えば丸線の場合であれば、丸線同士は
線接触であり、コイル状に曲げたとしたならば、
お互いの摩擦によつて皮膜は剥離する危険が生ず
る。 For example, if this is a round wire, the round wires are in line contact with each other, and if they are bent into a coil shape,
There is a risk that the coating will peel off due to mutual friction.
発明の効果
(1) 圧縮成形したのち、酸化銅皮膜16を形成で
きるので、圧縮時に素線絶縁が剥離するという
心配がない。Effects of the invention (1) Since the copper oxide film 16 can be formed after compression molding, there is no worry that the wire insulation will peel off during compression.
(2) 占積率が大変良い。(2) The space factor is very good.
すなわち、例えば0.8mmφの丸線を使用する
従来の絶縁電線の場合は、エナメル皮膜の厚み
は通常40μmなので素線のみの占積率でも82.6
%となり、17.4%の損失はきわめて大きくな
る。 For example, in the case of conventional insulated wires that use round wires of 0.8 mmφ, the thickness of the enamel coating is usually 40 μm, so even the space factor of the bare wire alone is 82.6.
%, and a loss of 17.4% is extremely large.
しかし本発明の酸化銅皮膜16を形成したも
のの場合は99.75%となり、損失分は微小の
0.25%である。 However, in the case of the copper oxide film 16 of the present invention, the loss is 99.75%, and the loss is minute.
It is 0.25%.
(3) 酸化銅皮膜16はエナメル皮膜14に比べて
油を劣化させる程度が低いので、油入り機器に
も適する。(3) Since the copper oxide film 16 degrades oil to a lesser extent than the enamel film 14, it is also suitable for oil-filled equipment.
(4) 耐熱性の高かいエナメル線を使用すると作業
工程が複雑となり、かつ高価であるが、本発明
は、素線絶縁が酸化銅皮膜のみであり、本質的
に耐熱性が高いため、絶縁層のみ耐熱性の良い
フイルムを使用すれば良いこととなり、作業工
程が簡単で、耐熱性向上が容易に可能になる。(4) Using enamelled wire with high heat resistance complicates the work process and is expensive; however, in the present invention, the wire insulation is only a copper oxide film, which inherently has high heat resistance, so Since it is only necessary to use a film with good heat resistance for the layer, the work process is simple and heat resistance can be easily improved.
