【産業上の利用分野】[Industrial applications]

本考案は、電磁誘導機器用コイル装置に関する。 The present invention relates to a coil device for electromagnetic induction equipment.

【0002】[0002]

【従来の技術】[Prior art]

電磁誘導機器例えば変圧器は、図4に示すように鉄心Aに低圧コイルBおよび 高圧コイルCを巻装して構成される。このようなコイル特に高圧コイルは、図3 に示すように絶縁筒1に第1層目の巻線2を複数ターンにわたって巻装し、次に 層間紙3を介して第2層目の巻線4を同じく複数ターンにわたって巻装する。以 下同様にして各層毎に巻線5を層間紙3を介して複数ターンにわたって巻装して 構成される。6は第1層目の巻線の端部に設置される沿面バンドである。 An electromagnetic induction device, such as a transformer, is constructed by winding a low voltage coil B and a high voltage coil C around an iron core A as shown in FIG. Such a coil, especially a high-voltage coil, has a winding 1 of the first layer wound around the insulating cylinder 1 over a plurality of turns as shown in FIG. 3, and then a winding of the second layer through an interlayer paper 3. Wind 4 in multiple turns as well. In the same manner as described below, the winding 5 is wound on each layer through the interlayer paper 3 for a plurality of turns. Reference numeral 6 is a creeping band installed at the end of the first layer winding.

【0003】 このような構成のコイルにおいては、第1層目の巻線2の巻始め部分である1 ターン目の巻線2Aに連なるリード線7を外部に引き出す必要があるが、従来で は図3に示してあるように、このリード線7を、第2層目の巻線4のうちの1タ ーン目の巻線4Aの外側から外部に引き出すようにしていた。In the coil having such a configuration, the lead wire 7 connected to the first-turn winding 2A, which is the winding start portion of the first-layer winding 2, needs to be pulled out to the outside. As shown in FIG. 3, the lead wire 7 is drawn to the outside from the outside of the first turn winding 4A of the second layer winding 4.

【0004】 しかしこのようにしてリード線7を引き出した場合、そのリード線7は巻線4 Aより外側に出っ張るようになり、そのためこの部分に電界が集中し、部分放電 が発生しやすくなる欠点がある。However, when the lead wire 7 is drawn out in this manner, the lead wire 7 is projected outside the winding 4 A, so that the electric field is concentrated in this portion and partial discharge easily occurs. There is.

【考案が解決しようとする課題】[Problems to be solved by the device]

本考案は、複数層にわたって巻線を巻装してコイルを構成するにあたり、第1 層目の巻線の巻始めのリード線部分における電界集中を緩和して、部分放電の発 生を抑制することを目的とする。 According to the present invention, when winding is wound over a plurality of layers to form a coil, the electric field concentration in the lead wire portion of the winding start of the first layer is relaxed to suppress the occurrence of partial discharge. The purpose is to

【0006】[0006]

【課題を解決するための手段】[Means for Solving the Problems]

本考案は、第1層目の巻線の巻始めのリード線を、第2層目の巻線のターン間 から外部に引き出すようにしたことを特徴とする。 The present invention is characterized in that the lead wire at the beginning of winding of the first layer winding is drawn out from between the turns of the second layer winding.

【0007】[0007]

【作用】[Action]

第1層目の巻線の巻始めのリード線を、第2層目の巻線のターン間から外部に 引き出すようにしたことにより、そのリード線の外側には第2層目の巻線のうち の少なくとも1ターン目の巻線が巻回されるようになる。このためリード線の外 側は巻線によって覆われるようになり、これによってリード線が外側に向かって 出っ張るようなことはなくなり、したがってこの部分での電界の集中が緩和され るようになる。 The lead wire at the beginning of the winding of the first layer is pulled out to the outside between the turns of the winding of the second layer, so that the lead wire of the second layer is placed outside the lead wire. At least the first turn of them will be wound. Therefore, the outer side of the lead wire is covered with the winding wire, which prevents the lead wire from protruding outward, and thus the concentration of the electric field at this portion is alleviated.

【実施例】【Example】

本考案の実施例を図1によって説明する。なお図3と同じ符号を付した部分は 同一または対応する部分を示す。本考案にしたがい、巻線2Aに連なるリード線 7を、第2層目の巻線4のうち、1ターン目の巻線4Aと、2ターン目の巻線4 Bとの間から外部に引き出すようにしている。したがって巻線4Aはリード線7 の外側に巻回されるようになる。 An embodiment of the present invention will be described with reference to FIG. In addition, the portions denoted by the same reference numerals as those in FIG. 3 indicate the same or corresponding portions. According to the present invention, the lead wire 7 connected to the winding 2A is drawn to the outside from between the first-turn winding 4A and the second-turn winding 4B of the second-layer winding 4. I am trying. Therefore, the winding 4A is wound outside the lead wire 7.

【0009】 このようにして巻線4Aをリード線7の外側に巻回すると、リード線7の引出 部分の外面は緩やかな弧状となった巻線4Aにより覆われるようになり、図3の ようなリード線7による出っ張りは解消される。これによりこの部分の電界の集 中は緩和され、部分放電の発生は抑制されるようになる。When the winding 4A is wound on the outside of the lead wire 7 in this way, the outer surface of the lead-out portion of the lead wire 7 is covered with the winding 4A having a gentle arc shape, as shown in FIG. The protrusion caused by the lead wire 7 is eliminated. As a result, the concentration of the electric field in this portion is relaxed, and the occurrence of partial discharge is suppressed.

【考案の効果】[Effect of device]

以上説明したように本考案によれば、コイルを構成する巻線のうち、第1層目 の巻線の1ターン目に連なるリード線を、第2層目の巻線のターン間から引き出 すようにしたので、リード線の引出部分における電界の集中は緩和され、部分放 電の発生を従来構成に比較して十分に抑制することができる効果を奏する。 As described above, according to the present invention, among the windings forming the coil, the lead wire connected to the first turn of the first layer winding is drawn out between the turns of the second layer winding. As a result, the concentration of the electric field at the lead-out portion of the lead wire is relaxed, and the effect of being able to sufficiently suppress the occurrence of partial discharge as compared with the conventional configuration.
