【発明の詳細な説明】
本発明は空心リアクトルの磁気シールド締付装置に関す
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magnetic shield tightening device for an air-core reactor.
空心リアクトルは発生磁束が全て漏れ磁束となるため、
この発生磁束量が大きい場合には、巻線の外周の一部に
、第１図に示すように強磁性体である硅素鋼板の如き鉄
板を積層して、閉磁気回路を構成する磁気シールド１（
単相の場合を示す）を設ける構造とすることが多い。In an air-core reactor, all of the magnetic flux generated becomes leakage flux, so
If the amount of generated magnetic flux is large, a magnetic shield 1 that forms a closed magnetic circuit by laminating an iron plate such as a ferromagnetic silicon steel plate on a part of the outer periphery of the winding as shown in FIG. (
(Single-phase case shown)) is often used.
すなわち、磁気シールドを設けることにより、発生磁束
の大部分をこの磁気シールドで吸収し、漏れ磁束を少な
くする。That is, by providing a magnetic shield, most of the generated magnetic flux is absorbed by the magnetic shield, thereby reducing leakage magnetic flux.
ところで、このように発生磁束の大部分を磁気シールド
で吸収すると、この吸収磁束により磁気シールドには常
に磁気吸引力が働くため、磁気シールドは強固に締付け
る必要がある。By the way, when most of the generated magnetic flux is absorbed by the magnetic shield in this way, a magnetic attraction force is always exerted on the magnetic shield due to the absorbed magnetic flux, so the magnetic shield needs to be firmly tightened.
磁気シールドの締付方法としては、ボルトによる締付け
、バインドの巻回による締付けがあるが、磁気シールド
の断面形状より従来はボルトによる締付けが一般的であ
る。Methods for tightening the magnetic shield include tightening with bolts and tightening with winding of a bind, but conventionally, due to the cross-sectional shape of the magnetic shield, tightening with bolts is common.
すなわち、磁気シールドの積厚寸法は漏れ磁束を少なく
するために巻線の外径に近い値がそれ以上となり、磁気
シールドの断面形状は、第２図に示すように、幅寸法ｌ
より積厚寸法Ｌの力が犬である長方形となる。In other words, the stacking thickness of the magnetic shield is set to a value closer to the outer diameter of the winding to reduce leakage magnetic flux, and the cross-sectional shape of the magnetic shield is set to a width l as shown in Figure 2.
Therefore, it becomes a rectangle in which the force of the stacking thickness dimension L is a dog.
したがって、第３図に示すように、バインド２で締付け
ても、これを矢印力向に引張った場合には点線で示すよ
うに変形する。Therefore, as shown in FIG. 3, even if the bind 2 is tightened, when it is pulled in the direction of the force indicated by the arrow, it deforms as shown by the dotted line.
つまり、Ｌ＞ｌであるため、バインド２による張力が充
分でなく、積厚刀向の締付けが不充分となる。In other words, since L>l, the tension by the bind 2 is not sufficient, and the tightening in the direction of the laminated thick blade is insufficient.
そのため、ボルトによる締付けが一般に行なわれていた
。For this reason, bolts were generally used for tightening.
しかしながら、ボルトによる締付けの場合、磁気シール
ドの鉄板の１枚１枚にボルトを通す穴をあける必要があ
り、かつボルトを絶縁しなければならないなど、磁気シ
ールドの鉄板の性能を損なう上に、作業も面倒であった
。However, when tightening with bolts, it is necessary to drill holes for the bolts to pass through each steel plate of the magnetic shield, and the bolts must be insulated, which impairs the performance of the steel plates of the magnetic shield and makes the work difficult. It was also a hassle.
本発明はこれらの点に鑑みてなされたもので、その目的
は、バインドにより容易にかつ強固に締付け得る空心リ
アクトルの磁気シールド締付装置を提供するにある。The present invention has been made in view of these points, and an object thereof is to provide a magnetic shield tightening device for an air-core reactor that can be easily and firmly tightened by binding.
この目的を達成するため、本発明は、磁気シールドの積
厚力向に１個所以上の間隙を設け、この間隙に配置する
バインド締付手段を利用して磁気シールドを締付けるバ
インドを絞り、バインドの締付まを強固にしたことを特
徴とする。In order to achieve this object, the present invention provides a gap at one or more locations in the direction of the stacking force of the magnetic shield, and utilizes a bind tightening means disposed in this gap to squeeze the bind that tightens the magnetic shield. It is characterized by strong tightening.
すなわち、第４図に示すように、磁気シールド１の積厚
方向に間隙３を設け、この間隙３を利用して締付装置４
によりバインド２を図示にように絞れば、積層方向の締
付けが充分となる。That is, as shown in FIG. 4, a gap 3 is provided in the stacking thickness direction of the magnetic shield 1, and the tightening device 4 is installed using this gap 3.
If the bind 2 is tightened as shown in the figure, sufficient tightening in the stacking direction will be achieved.
以下、本発明の一実施例を第５図ないし第９図について
説明する。An embodiment of the present invention will be described below with reference to FIGS. 5 to 9.
第５図は平面図、第６図は正面図、第７図は側面図、第

空心リアクトルの巻線５は巻線支持リング６を介して磁
気シールド１で支持されている。The winding 5 of the air-core reactor is supported by the magnetic shield 1 via a winding support ring 6.
磁気シールド１は当板７，８を介してバインド２で締付
けられ、このように締付けられた磁気シールド１はさら
に締付ロツド９を介して締金具１０により締付けられて
一体に構成されている。The magnetic shield 1 is tightened with a bind 2 via the contact plates 7 and 8, and the magnetic shield 1 thus tightened is further tightened with a fastener 10 via a tightening rod 9 to form an integral structure.
磁気シールド１には、間隙３が設けられ、この間隙３内
には、間隙ダクト１１が挿入されている。A gap 3 is provided in the magnetic shield 1, and a gap duct 11 is inserted into the gap 3.
また、間隙３にはバインド締付手段となるロツド１２が
挿通され、このロツド１２に連結された締付金具１３，
１４によりバインド２が絞られるようになされている。Further, a rod 12 serving as a bind tightening means is inserted into the gap 3, and a tightening fitting 13 connected to this rod 12,
14, the bind 2 is tightened.
なお、ロツド１２と一方の締付金具１３は移動自在に連
結され、ロツド１２と他方の締付金具１４は溶接、接着
などで固定されている。Note that the rod 12 and one of the fastening metal fittings 13 are movably connected, and the rod 12 and the other fastening metal fitting 14 are fixed by welding, gluing, or the like.
そのため、ナット１５で両締付金具１３，１４間の間隙
を狭めるように締付金具１３を移動することにより、前
記のようにバインド２を絞ることができる。Therefore, by moving the tightening fitting 13 with the nut 15 so as to narrow the gap between the two tightening fittings 13 and 14, the bind 2 can be tightened as described above.
また、締付金具１３．１４はそれぞれ絶縁材で製作する
こともできる。The fasteners 13, 14 can also each be made of an insulating material.

この実施例では、締付金具１３の代りに両間隙３に跨が
る締付金具１６を用い、その両端でＵ字形ボルト１７に
よりバインド２を締付けている。In this embodiment, instead of the fastening fitting 13, a fastening fitting 16 is used which spans both gaps 3, and the bind 2 is tightened with U-shaped bolts 17 at both ends thereof.
このため、磁気シールド１と締付金具１６の間には絶縁
材からなる下敷１８を配置する。For this reason, an underlay 18 made of an insulating material is placed between the magnetic shield 1 and the fastening fitting 16.
また、バインド２の絞りは前記実施例と同様にバインド
締付手段によって行なうことができる。Further, the binding 2 can be narrowed by the binding tightening means as in the above embodiment.
なお、前記各実施例では、締付ロツド９が当板７を貫通
しているが、貫通させなくとも締付けには何ら影響がな
い。In each of the embodiments described above, the tightening rod 9 passes through the contact plate 7, but even if it does not pass through the plate 7, there is no effect on tightening.
また本発明は単相の場合に限らず、３相の場合にも同様
に適用できる。Further, the present invention is applicable not only to a single phase case but also to a three phase case.
