する。[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an air-core reactor used in a large-capacity rectifier using a thyristor, etc., and in particular, to prevent the generation of vibration noise between conductors caused by electromagnetic force. The present invention relates to an air-core reactor in which an insulating film or an El-sa is inserted between conductors.

を締結するようにしたものがある。In an air-core reactor, when a rectangular wave or an alternating current flows through its conductors, an attractive force or a repulsive force acts between the conductors, which may generate vibration noise. Therefore, in order to prevent the generation of the above-mentioned vibration noise, there have conventionally been methods in which an insulating sweep is inserted between the conductors, and a portion of the conductor and the insulating sweep are fastened together using a bind chain.

が介挿されている。FIG. 1(,)(b) is a diagram showing an example of such a conventional air-core reactor. In the figure, l is an air-core reactor main body, which is a helically wound conductor 11 having a rectangular cross section. A spacer 2 is provided between the conductors 1 and 2.
is inserted.
そして、上記導体11と絶縁スイープ2はその周囲にバ
インドテープ3を巻回することにより締結されている。The conductor 11 and the insulating sweep 2 are connected to each other by wrapping a bind tape 3 around them.
なお図に示した従来例においては、上記の如き締結箇所

ジ部11aにおいてバインドチー703が応力集中を起
こして切れやすく、耐久性に欠ける。In the conventional structure having the above-mentioned structure, the binding chips 703 tend to break due to stress concentration at the edge portions 11a at both ends of the rectangular conductor 11, and lack durability.
第2図はバインドテープ3の強度と前記エツジ部11a
の形状との関係を示したものである。FIG. 2 shows the strength of the bind tape 3 and the edge portion 11a.
This shows the relationship between the shape and the shape.

3の強度はさらに向上することがわかる。In the figure, the vertical axis is the strength reduction rate of the bind chi 7°3 at the edge portion 11h, with the original strength being 1. Further, C and R on the horizontal axis are the dimensions of the chamfering applied to the edge portion 11m, where C indicates the planar shape and R indicates the degree of the circular arc-shaped chamfer. As can be seen from FIG. 2, when C and R are O, that is, when the edge portion 11h is not chamfered at all, the strength of the bind tape 3 becomes the original strength, and when C and R are 1 m++, each is A. The strength will be approximately. It can be seen that the strength of the bind tape 3 is hardly improved even if the value of C is set to 1 m or more, whereas the strength of the bind tape 3 is further improved when the value of R is set to 1 m or more.
しかし、エツジ部11aに1商ず円孤状の面取りを大き

するため、電流密度が高くなり発熱量が増加して効率の
低下を招く。However, if the arcuate chamfer is made larger than the edge 11a, the cross-sectional area of the conductor 1 will locally decrease, resulting in higher current density and increased heat generation, leading to a decrease in efficiency. .

なり、信頼性に欠けるという問題があった。In addition, generally, the winding start end of the bind tape 3 is adhered to the conductor 11 with adhesive tape, etc., but with such means, it is difficult to apply a large tension when starting to wind the bind tape 3 around the conductor 11 and the insulating spacer 2. I can't. Therefore, as the binding tape 3 is wound overlappingly, wrinkles occur at the beginning of the winding due to the tightening of the bind tape 3, and as a result, the connection between the conductor 11 and the insulating strainer 2 becomes unstable, resulting in a lack of reliability. There was a problem.
