Abstract
The purpose of the present invention is to ensure insulation distances among tap lead parts, and to decrease the height of a coil, so as to reduce the size of a transformer. In order to facilitate the connection of tap lead lines, a straight line part of a long side of a coil cross-section is not curved along the outer circumference but is extended straightly, so as to protrude in a coil radial direction, outward with respect to an outermost circumferential conductive part of another turn of the coil. Protrusion distances in the coil radial direction are adjusted so that tap lead parts (6b') and (6d') are arranged so as to protrude in the coil radial direction, outward with respect to tap lead parts (6a'), (6c'), and (6e'). By doing so, insulation distances among the tape lead parts are ensured, and the number of turns between tap lead part lines is decreased, whereby the size of the coil can be reduced.

しかしながら、上述した技術では未だ、以下のように改善が必要な点があった。即ち、エッジワイズ巻線のタップ引出し部において、タップ引出し部を必ずコイルの外周ターンとするとともに各タップ引き出し部間の絶縁距離を確保するため、コイルの軸方向に３段以上空けてタップ引き出し線を設けるような巻線構造としており、この巻線構造ではコイル高さが高くなり、コイルとして用いる導体は長く、樹脂層が大きくなることから変圧器全体が大型化してしまい、更には変圧器の材料費が高くなってしまっていた。
However, the above-described technology still requires improvement as follows. That is, in the tap lead portion of the edgewise winding, the tap lead portion is always used as the outer peripheral turn of the coil, and in order to secure an insulation distance between the tap lead portions, the tap lead wire is provided with three or more steps in the axial direction of the coil. In this winding structure, the coil height is high, the conductor used as the coil is long, the resin layer is large, and the entire transformer is enlarged, and further, the transformer Material costs were high.
本発明は、上記課題を解決するためになされたものであり、導体をコイル径方向の外周から内周へと渦巻状に巻線し、最内周まで巻線したら段上がりして内周から外周へ向かって巻線する。これを高さ方向に積層していく。これを繰り返し行うことにより、コイルを形成する。ここで、タップ引出し部が必ずコイルの外周ターンとなるように１段当たりの巻き回数を減じさせた段を組み合わせてコイルを形成する。また、導体の引出しも巻線作業を中断することなく、連続で行えるよう、タップ引出し部となる回数のところでコイル外周から一部突出させたターンを形成させ、その後のタップ端子の接続を容易にする。その際、タップ引出し部をコイル径方向内側と外側に交互にずらして配置することでコイル軸方向だけでなくコイル径方向にも絶縁距離を確保する。上記のような静止誘導機器コイルの構成によれば、巻線スペースを効率化でき、各タップ間の絶縁距離を確保しつつコイル高さ低減を図れる。
The present invention has been made in order to solve the above-mentioned problem, and the conductor is wound in a spiral shape from the outer periphery in the coil radial direction to the inner periphery, and when it is wound up to the innermost periphery, it is stepped up from the inner periphery. Wind toward the outer circumference. These are stacked in the height direction. By repeating this, a coil is formed. Here, the coil is formed by combining the stages in which the number of windings per stage is reduced so that the tap drawing portion is always the outer peripheral turn of the coil. In addition, the conductor can be drawn continuously without interrupting the winding work, so that a part of the tap lead-out portion is formed at the number of times of the tap lead-out portion so that a subsequent tap terminal can be easily connected. To do. At that time, the tap lead-out portions are alternately shifted inward and outward in the coil radial direction to secure an insulation distance not only in the coil axial direction but also in the coil radial direction. According to the configuration of the static induction device coil as described above, the winding space can be made efficient, and the coil height can be reduced while ensuring the insulation distance between the taps.

According to the present invention, the height of the stationary induction device coil can be reduced, and a smaller, lighter and more economical stationary induction device coil can be provided.
以下、本発明の静止誘導機器コイルの実施例について、図面を用いて説明する。
本発明の実施例について、図１乃至７に基づいて説明する。本実施例は、平角線導体をコイルの円筒形方向に巻き付けた段を軸方向に積層し、タップを設けて構成したコイルである。図１は、本実施例に適用するコイルの例としてモールドコイル１０を示す。導体１の巻始め３をコイル外側の端部から行い、図１および図８中の導体１に付した数字の順にコイル径方向の外周から内周へ向かって複数回巻付けて段を形成したあと、上段へ上がり次に内周から外周へ向かって巻き付ける。これを規定の巻数まで繰り返すことでコイルの形状とし、樹脂層２を形成する。 Hereinafter, embodiments of the static induction device coil of the present invention will be described with reference to the drawings.
An embodiment of the present invention will be described with reference to FIGS. The present embodiment is a coil in which a step in which a flat wire conductor is wound in the cylindrical direction of the coil is laminated in the axial direction and a tap is provided. FIG. 1 shows amolded coil 10 as an example of a coil applied to this embodiment. The winding start 3 of the conductor 1 was performed from the outer end of the coil, and a step was formed by winding a plurality of turns from the outer periphery to the inner periphery in the coil radial direction in the order of the numbers given to the conductor 1 in FIGS. After that, it goes up and then winds from the inner circumference to the outer circumference. By repeating this up to a specified number of turns, a coil shape is formed, and the resin layer 2 is formed.
本発明の実施例について、図１乃至７に基づいて説明する。本実施例は、平角線導体をコイルの円筒形方向に巻き付けた段を軸方向に積層し、タップを設けて構成したコイルである。図１は、本実施例に適用するコイルの例としてモールドコイル１０を示す。導体１の巻始め３をコイル外側の端部から行い、図１および図８中の導体１に付した数字の順にコイル径方向の外周から内周へ向かって複数回巻付けて段を形成したあと、上段へ上がり次に内周から外周へ向かって巻き付ける。これを規定の巻数まで繰り返すことでコイルの形状とし、樹脂層２を形成する。 Hereinafter, embodiments of the static induction device coil of the present invention will be described with reference to the drawings.
An embodiment of the present invention will be described with reference to FIGS. The present embodiment is a coil in which a step in which a flat wire conductor is wound in the cylindrical direction of the coil is laminated in the axial direction and a tap is provided. FIG. 1 shows a
本実施例の樹脂モールドコイルは、平角線を成形してエッジワイズに曲げ加工を行いながらコイルを成形するものである。特に矩形形状のコイルのときは、平角線を直線部と曲げ部に分け、それぞれ異なる成形方法を行う。たとえば、図２（ａ）（ｂ）に示すコイル成形機を使用し、上下に設置されたローラ５、５の間に平角線１を通し、電線成形部４によりローラ５の角度を変更させることで導体１にＲの癖を付ける。この方法によれば、任意のＲを有する平角線からなる導体１を成形出来、また丸型コイル、矩形コイルとも製作可能である。成形中のコイルの斜視図を図３に示す。
The resin-molded coil of this example is a coil that is formed while forming a flat wire and bending it edgewise. In particular, in the case of a rectangular coil, the flat wire is divided into a straight portion and a bent portion, and different forming methods are performed. For example, using the coil forming machine shown in FIGS. 2 (a) and 2 (b), the rectangular wire 1 is passed between the rollers 5 and 5 installed at the top and bottom, and the angle of the roller 5 is changed by the wire forming portion 4. Then, attach a ridge of R to conductor 1. According to this method, the conductor 1 made of a rectangular wire having an arbitrary R can be formed, and both a round coil and a rectangular coil can be manufactured. A perspective view of the coil being formed is shown in FIG.
かかるコイルにおいて、図４（ａ）～（ｃ）に示すようにコイルをその巻始め部３から巻き終りまで成形し、このコイルからタップ電圧に応じた所定の巻き回数よりタップリード線を取り付ける導体部分（タップ引出し部）６ａ～６ｅとタップ切換部のタップ端子とをタップリード線で接続する。そしてこのタップリード線を取り付ける位置は、絶縁処理が省けること、コイル内に無用なスペースを作らずに済むことから、コイルの最外周側に配置する。
In such a coil, as shown in FIGS. 4 (a) to 4 (c), a coil is formed from its winding start portion 3 to the end of winding, and a conductor to which a tap lead wire is attached from this coil by a predetermined number of turns according to the tap voltage. The portions (tap drawer portions) 6a to 6e and the tap terminals of the tap switching portion are connected by tap lead wires. And the position which attaches this tap lead wire is arrange | positioned in the outermost periphery side of a coil, since it can omit an insulation process and does not need to make a useless space in a coil.
図５は、図４と同様に導体を巻回したコイルを示している。図４に示すコイルとは、最外周にあるタップ引出し部６ａ’～６ｅ’をコイル径方向内側と外側に交互にずらして配置した点において相違する。
FIG. 5 shows a coil wound with a conductor as in FIG. The coil shown in FIG. 4 is different from the coil shown in FIG. 4 in that tap lead portions 6a 'to 6e' on the outermost periphery are alternately shifted inward and outward in the coil radial direction.
内側のタップ引き出し部と外側のタップ引き出し部とのコイル径方向の距離ｄは、タップ引き出し部の絶縁距離をＥ、隣接するタップ引き出し線におけるコイルの軸方向の距離をｈとすると、少なくとも下記の式（数１）を満たすものである必要がある。ただし、タップ引き出し部にタップリード線を接続した場合、タップリード線を含めた導体間で絶縁距離を確保する必要がある。
The distance d in the coil radial direction between the inner tap lead portion and the outer tap lead portion is at least the following, where E is the insulation distance of the tap lead portion and h is the axial distance of the coil in the adjacent tap lead wire: It is necessary to satisfy the formula (Equation 1). However, when a tap lead wire is connected to the tap lead portion, it is necessary to ensure an insulation distance between conductors including the tap lead wire.
図５に示すコイルによれば、例えばタップ引き出し部６ａ’とタップ引き出し部６ｂ’とは十分に距離が離れていることから各々のタップ引き出し部間の距離は絶縁距離以上とすることができ、更にタップ引き出し部６ａ’とタップ引き出し部６ｃ’の間でも十分な
距離とすることができる。即ち、各タップ引き出し部は各々の間で絶縁距離を確保することができ、これによりコイル軸方向に２段少なく導体を巻回してタップ引き出し部を延設することができ、コイルの高さを低減することができる。 According to the coil shown in FIG. 5, for example, the distance between thetap lead portions 6a ′ and the tap lead portion 6b ′ is sufficiently long from the tap lead portions 6b ′, so that the distance between the tap lead portions can be equal to or greater than the insulation distance. Further, a sufficient distance can be provided between the tap lead portion 6a ′ and the tap lead portion 6c ′. That is, each tap lead-out portion can secure an insulation distance between them, and thereby the tap lead-out portion can be extended by winding a conductor two fewer steps in the coil axial direction. Can be reduced.

次に、図５に示すコイルにおける導体引出し方法について述べる。図５のように、タップリード線を接続しやすくするため、コイル断面の長辺の直線部を外周に沿って曲げるのではなく、そのまま延ばし、コイルの他の段の最外周の導体部分よりもコイル径方向に突出させている。コイル径方向の突出距離を調整し、タップ引出し部６ｂ’、６ｄ’をタップ引出し部６ａ’、６ｃ’、６ｅ’よりもコイル径方向に対して外側に突出させて配置することで、タップ引き出し部間の距離をかせぐことができる。図６は、導体引き出し後のコイルを示す斜視図である。図のように取り付けるタップの数だけ、導体を突出させてタップ引き出し部を形成した構造となる。タップ切換器端子部までの接続は、図７（ａ）（ｂ）のように端子８ａ～８ｅが付いたリード線９をコイル１のタップ引出し部に接続する。
Next, the conductor drawing method in the coil shown in FIG. 5 will be described. As shown in FIG. 5, in order to facilitate the connection of the tap lead wires, the straight side portion of the long side of the coil cross section is not bent along the outer periphery, but is extended as it is, rather than the outermost conductor portion of the other stage of the coil. It protrudes in the coil radial direction. By adjusting the protrusion distance in the coil radial direction and arranging the tap lead portions 6b ′ and 6d ′ so as to protrude outward from the tap lead portions 6a ′, 6c ′ and 6e ′ in the coil radial direction, You can earn a distance between parts. FIG. 6 is a perspective view showing the coil after the conductor is drawn out. As shown in the figure, the conductor is protruded by the number of taps to be attached to form a tap lead portion. For connection to the tap changer terminal portion, lead wires 9 having terminals 8a to 8e are connected to the tap lead portion of the coil 1 as shown in FIGS.
以上実施例で説明したように、本発明によれば、タップ線を設けた静止誘導機器コイルをコンパクトに製作することができる。なお、本発明は、コイルを必要とする静止誘導機器すべてに適用可能である。
