Description
【発明の詳細な説明】 産業上の利用分野 本発明は電気機器用条巻線に関するものである。[Detailed description of the invention] Industrial applications The present invention relates to a strip winding wire for electrical equipment.
従来の技術
一般に電気機器用巻線１は、巻線から発生するジュール
熱を巻線外部に放熱するために、第４図に示すように、
巻線相互間に冷却ダクト２を設け、冷却媒体を巻線下部
から上部へ自然対流させる構成となっている。BACKGROUND OF THE INVENTION In general, a winding 1 for electrical equipment has a winding as shown in FIG. 4, in order to radiate Joule heat generated from the winding to the outside of the winding.
A cooling duct 2 is provided between the windings to allow natural convection of the cooling medium from the lower part of the winding to the upper part.
従来の条巻線相互間に冷却ダクトを設ける方法としては
、巻線の途中において第６図に示すような棒状スペーサ
を巻線の上に接着テープ４で固定し、これを巻線相互間
に巻き込むことによって、冷却ダクトを構成していた。The conventional method of providing a cooling duct between the windings is to fix a bar-shaped spacer as shown in FIG. By rolling it up, a cooling duct was constructed.
発明が解決しようとする課題
しかし、このような従来の構成では、あらかじめ棒状ス
ペーサをテープ状絶縁材に一定間隔で取り付は準備して
おく必要があるが、電気機器の種類ごとに、棒状スペー
サの長さおよび取付本数が異なるために部品点数が多く
なるという欠点があった。Problems to be Solved by the Invention However, in such a conventional configuration, it is necessary to prepare the rod-shaped spacers to be attached to the tape-shaped insulating material at regular intervals in advance. The disadvantage is that the number of parts increases because the lengths and the number of attachments are different.
本発明は上記従来の欠点に鑑みてなされたもので、簡単
な構成で冷却ダクトを形成することを目的としたもので
ある。The present invention has been made in view of the above-mentioned conventional drawbacks, and an object of the present invention is to form a cooling duct with a simple structure.
課題を解決するための手段
上記課題を解決するため、本発明は条巻線そのものの一
部を加工して多数の突起を設け、これらの突起によシ隣
接する巻線との間に冷却ダクトを構成する中空部を形成
するものである。Means for Solving the Problems In order to solve the above problems, the present invention processes a part of the winding wire itself to provide a large number of protrusions, and a cooling duct is installed between these protrusions and adjacent windings. It forms the hollow part that constitutes the.
作 用
本構成により従来のような棒状スペーサを不要となるた
め、部品点数を大幅に削減できることとなる。The main structure eliminates the need for rod-shaped spacers as in the past, making it possible to significantly reduce the number of parts.
実施例
以下、本発明の一実施例について図面に基づいて説明す
る。EXAMPLE Hereinafter, an example of the present invention will be described based on the drawings.
第２図において６は条巻線であり、６は層線相互間絶縁
紙である。巻線相互間に冷却ダクトを形成するために、
条巻線５の一部に適当な型を用いたプレス加工などによ
り突起部７を多数設ける。In FIG. 2, 6 is a strip wound wire, and 6 is an insulating paper between layer wires. To form cooling ducts between the windings,
A large number of protrusions 7 are provided on a portion of the wire winding 5 by pressing using a suitable die.
突起部の形状は、第３図に示すように、巻線相互間絶縁
紙６に損傷を与えないよう円形とし、条巻線の端部には
かからないものとする。８寸法は条巻線の板厚を以上の
寸法とする。As shown in FIG. 3, the shape of the protrusion is circular so as not to damage the insulating paper 6 between the windings, and does not extend over the ends of the windings. Dimension 8 is the thickness of the wound wire.
突起部先端の外径Ａと突起部の数は巻線時のテンシ冒ン
および相互間圧力に応じて選定し、必要に応じて相互間
絶縁紙６の補強紙８を取り付ける。The outer diameter A of the tips of the protrusions and the number of protrusions are selected depending on the tensile strength and mutual pressure during winding, and reinforcing paper 8 of the insulating paper 6 is attached between the two as necessary.
ので冷却ダクトを構成するために、従来の棒状スペーサ
は不要となり、材料面でより経済的な巻線を提供するこ
とができる。Therefore, the conventional rod-shaped spacer is no longer necessary to construct the cooling duct, and a winding wire that is more economical in terms of materials can be provided.
又、冷却ダクト内部において条巻線と冷却媒体の接触面
積が増大するため巻線の冷却効果が向上する。Further, since the contact area between the strip winding and the cooling medium increases inside the cooling duct, the cooling effect of the winding is improved.
