【考案の詳細な説明】
本考案は、スペーサフレーム本体が多導体送電線の内側
に配置されているスペーサフレームに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a spacer frame in which the spacer frame body is disposed inside a multi-conductor power transmission line.
スペーサフレーム本体が多導体送電線の内側に配置すし
ているスペーサフレームは、スペーサフレーム本体が多
導体送電線の外側に配置されているスペーサフレームに
に比べて、寸法及び重量が小さく、また作業能率等に関
して、有利であり、４導体以上の多導体送電線にはスペ
ーサフレームに正多角形又は円形フレームが使用されて
いる。A spacer frame in which the spacer frame body is placed inside the multi-conductor power line has smaller dimensions and weight, and is more efficient in work efficiency than a spacer frame in which the spacer frame body is placed outside the multi-conductor power line. etc., it is advantageous to use a regular polygonal or circular frame for the spacer frame for multi-conductor transmission lines with four or more conductors.
即ち大径の鋼管を輪切りにするか小径の金属パイプを正
多角形又は円形に成形してフレームとし、これに所要数
のスペーサクランプを可動的に取付けている。That is, a large-diameter steel pipe is cut into rounds or a small-diameter metal pipe is formed into a regular polygon or circle to form a frame, and a required number of spacer clamps are movably attached to this frame.
送電線の容量が増大すると６導体或は８導体の多導体が
用いられ、これにつれてスペーサのフレームも大型とな
り、その径が７０ｃｍ乃至１．５仇或はこれ以上の大型
となり、これを一体物のフレームで構成すれば重量も大
きく、特に運搬上不便であった。As the capacity of power transmission lines increases, multi-conductors of 6 or 8 conductors are used, and as a result, spacer frames also become larger, with diameters ranging from 70 cm to 1.5 cm or larger, which makes it difficult to integrate them into one piece. If constructed with a frame, it would be heavy and particularly inconvenient to transport.

けにより一体に組立て、該ボルトを少くとも一部に角状
部を有するボルトと腰該ボルトの挿通孔を角孔とした。In view of this, the present invention provides a spacer frame for a multi-conductor power transmission line in which the main body of the spacer frame for a multi-conductor power transmission line is placed inside the multi-conductor power transmission line and a spacer clamp is attached to the spacer frame for the multi-conductor power transmission line. A power transmission line spacer frame main body is divided into n equal parts and assembled together by tightening bolts and nuts, and the bolts have at least a angular part at least in part, and the holes through which the bolts are inserted are square holes.
次にこれを図に示す実施例に基いて更に詳細に説明する
。Next, this will be explained in more detail based on the embodiment shown in the drawings.
第１図及び第２図は本考案になるスペーサフレームの一
例を示したもので、フレーム本体１は断面が長方形で円
環状をなし、二分割の場合を示す。1 and 2 show an example of a spacer frame according to the present invention, in which the frame main body 1 has a rectangular and annular cross section and is divided into two parts.
スペーサクランプ２はフレーム本体１に所望数取付ける
が、図において簡単にするため１個のみを示し、従来と
同様に可動的に取付ける。Although a desired number of spacer clamps 2 are attached to the frame body 1, only one is shown for simplicity in the figure, and they are movably attached as in the conventional case.
フレーム本体１は２分割であるから左右に部分され、そ
の連結部３，３は対称的に設ける。Since the frame body 1 is divided into two parts, it is divided into left and right parts, and the connecting parts 3, 3 are provided symmetrically.
一方の連結部３について詳述すれば第２図から明らかな

二つ割フレーム本体１を強固に確実に固定することがで
きる。Note that the insertion hole for the bolt 5 provided in the flat plate portion 4 is a square hole as shown in FIG. The split frame main body 1 can be firmly and reliably fixed.
更に図においては２等分の場合を示したが４等分、６等
分等対称的に分割した場合にも同様な構成により分割型
スペーサフレームとし、容易に一体のスペーサフレーム
とすることができる。Furthermore, although the figure shows a case where it is divided into two equal parts, even if it is divided into four equal parts, six equal parts, etc., a split type spacer frame can be created using the same structure, and it can easily be made into an integrated spacer frame. .
以上説明したように本考案によれば従来の正多角形又は
円形の多導体送電線用スペーサフレーム本体をｎ個に等

る等の実用的効果がある。As explained above, according to the present invention, the conventional regular polygonal or circular spacer frame body for multi-conductor power transmission lines is divided into n pieces, and these parts are assembled into one piece by tightening bolts and nuts. Since the frame body is small and has the same shape as 1/n, it has practical effects such as easy transportation to the site and easy transportation and assembly of the large spacer frame to a remote mountainous area.
本考案では、ｎ等分したスペーサフレーム本体を一体に
締付けたボルトを少くとも一部に角状部を有するボルト

本体の形状が特定され、フレーム本体が容易に歪まず、
導体送電線間隔の保持が確実となる。In the present invention, the bolt used to tighten the spacer frame body divided into n equal parts is a bolt that has at least a square part, and the insertion hole for this bolt is a square hole, so that the shape of the frame body can be specified. , the frame body is not easily distorted,
Maintaining the conductor transmission line spacing is ensured.
