Description
【発明の詳細な説明】 〔産業上の利用分野〕 本発明は真空遮断器に関するものである。[Detailed description of the invention] [Industrial application field] The present invention relates to a vacuum circuit breaker.
従来の真空遮断器は実開Ｉ１１Ｔ５ｇ−１２８５３７号
公報に記載されているように、枠体」−に設けた絶縁体
に主導体をそのまま固定するようになっていた。しかし
この構造の場合、主導体の床面からの取付レベル調整を
容易にする点については配慮されていなかった。In a conventional vacuum circuit breaker, as described in Japanese Utility Model Application No. I11T5g-128537, the main conductor is fixed to an insulator provided in a frame. However, in this structure, no consideration was given to facilitating adjustment of the mounting level of the main conductor from the floor surface.

の公差集積に依存するにもかかわらず、その調整を容易

問題があった。In the above conventional technology, even though the installation level of the main conductor from the floor depends on the tolerance accumulation of all parts, there is no consideration given to easily adjusting it, and the installation level of the main conductor is There was a problem in that it was difficult to reliably, quickly, and easily fit within the tolerance.
本発明は以上の点に鑑みなされたものであり、主導体の
取付レベル調整を短時間、かつ確実に行うことをｎｆ能

ある。The present invention has been made in view of the above points, and an object of the present invention is to provide a vacuum circuit breaker that is capable of adjusting the mounting level of the main conductor in a short time and reliably.
１−記目的は、主導体を、絶縁体との取付部が主導体の
軸中心線から夫々異なる寸法の面を有する多面体で形成
すると共に、主導体を回転させ多面体のいずれかの面を
絶縁体との取付面に選定することにより、達成される。The purpose of item 1-1 is to form the main conductor with a polyhedron whose mounting part with the insulator has faces with different dimensions from the axial center line of the main conductor, and to rotate the main conductor to insulate any surface of the polyhedron. This is achieved by selecting the mounting surface to the body.

付ける面に対する主導体の軸中心線の寸法を変化させる
ことができるので、高精度に、合せることができる。The mounting part of the main conductor is a polyhedron, and the distance between each face and its axial center line is different for all faces, so the dimension of the axial center line of the main conductor with respect to the face on which the main conductor of the insulator is mounted is:
It changes depending on which surface of the main conductor is used as the mounting surface, and it can be selected from multiple surfaces by rotating the main conductor around the axis center line. Therefore, the mounting level of the main conductor can be adjusted even if the surface of the insulator on which the main conductor is mounted has dimensions that are slightly out of tolerance, or even if the surface on which the main conductor is mounted is not manufactured with high precision. Since the dimensions of the body axis center line can be changed, alignment can be achieved with high precision.

寸法ｔｚからｔａの選定で対応できるようになる。Hereinafter, focusing on the main conductor 8, the installation of the main conductor 8,
explain about. The mounting level of the main conductor 8 is a dimension L2, and it is required that this mounting level dimension Lz be reliably within a tolerance of ±α. Since the main conductor 8 is fixed to the insulator 3 with bolts 4, the mounting height of the insulator 3 may be adjusted due to manufacturing errors of the insulator 3, manufacturing errors of the frame 1, and installation errors of the insulator 3 to the frame 1. The dimension H2 changes with the tolerance ±β, and the f2 w z between the mounting height dimension H2 and the mounting level dimension L2 will move slightly, but as mentioned above, the axis center line of the main conductor 8 is Since the directions 8a to 8d having different dimensions t1 to ta are formed, the variation in wi can be accommodated by selecting the dimensions tz to ta.
すなわちｗ２の大きさに応じて の時は寸法ｔｘを選定。That is, depending on the size of w2 In this case, select the dimension tx.

レベル寸法Ｌｚを公差内に確実に入れることができる。This can be handled by selecting the dimension ta. Therefore, even if the mounting height dimension Hz of the insulator 3 changes, the mounting level dimension Lz of the main conductor 8 can be reliably kept within the tolerance.

調整することができる。Of course, the variation range of the difference W2 between the mounting height dimension H2 of the insulator 3 and the mounting level dimension L2 of the main conductor 8 is generally 5 to 8 m.
The dimensions ti to t4 corresponding to this were also formed in a size range corresponding to this. In this way, the mounting level of the main conductor 8 can be adjusted reliably and easily without using or employing a jack-up method using adjustment fittings or bolts.

８０±２１１ＩＩＩにへ才しることができる。- As an example, the dimension tl from the axis center line of the main conductor 8 = 26 m
, tz = 18aw, ta = 22 mm, ta = 1
Using the main conductor 8 formed of 4++n, the mounting height dimension H2 of the insulator 3 = 700 mm, the mounting level dimension Lz of the main conductor 8 = 680 mm, the tolerance α of the mounting level dimension L2;
Consider the case where the tolerance β of the mounting height dimension H2 is adjusted by ±2 mm and ±6 m. Substituting the above-mentioned numerical values into the above-mentioned values yields 28>W2>24. In this case, machin = 26ma
When selecting , the mounting level of the main conductor 8 is the difference between tl and W2, that is, 28m+ -26mn+=2g+, 2
4 nu -26am= -21, which is the target of 6
It can be reduced to 80±211III.
