スタイ方式による母線装置に係り、特に母線導体の配置
構成に関するものである。[Detailed Description of the Invention] The present invention relates to a busbar device using a double busbar four-bus tie system in indoor and outdoor air-insulated substations, and particularly relates to the arrangement of busbar conductors.

一般に変電所等に於て、第１図の単線結線図で示すよう
に二重母線４ブスタイ方式により送受電を行う場合、実
際の導体配置も第１図で示すように配置構成される。Generally, in a substation or the like, when transmitting and receiving power using a double busbar four bus tie system as shown in the single line diagram of FIG. 1, the actual conductor arrangement is also arranged as shown in FIG.

即ち図示のように甲系統側母線導体１１ ａ 、１１
ｂ間及び乙系統側母線導体１２ａ、１２ｂ間をそれぞれ
断路器１３．１４を介して、母線連絡しゃ断器１５ ａ

１４及び分岐しゃ断器１６を介して送受電回線１８を引
き出すように構成している。That is, as shown in the figure, the A system side bus conductors 11a, 11
A busbar connection breaker 15a is connected between the busbar conductors 12a and 12b on the system B side and between the busbar conductors 12a and 12b via disconnectors 13 and 14, respectively.
Or, after connecting by 15 b, they are arranged almost in parallel, and between the bus conductors 11a and 12d of these two systems and between llb and 12
busbar connection breaker 15 via disconnector 13 and 14 between
C or 15d, and both line conductors 11
From between a, llb and 12a, 12b, the new circuit 13.
14 and a branch breaker 16, the power transmission/reception line 18 is drawn out.

この場合、送受電回線１８が多いと、変電所の形態が母
線導体１１．１２の長さ方向に沿った細長いものになっ
てしまう。In this case, if there are many power transmission/reception lines 18, the shape of the substation becomes elongated along the length direction of the bus conductors 11 and 12.

例えば６６ＫＶの屋内宗家式変電所に於て、送受電回線
１８を図示のように１６回線引き出す場合の概略寸法は
、母線の長さ方向で約１００ｍ、幅方向で約１２ｍとい
う極めて変則的な形態となってしまう。For example, in a 66KV indoor Soke-style substation, when 16 power transmission/reception lines 18 are drawn out as shown in the figure, the approximate dimensions are approximately 100 m in the length direction of the bus bar and approximately 12 m in the width direction, which is an extremely irregular form. It becomes.

従来このような母線配置で運用されていた主な理由は、
ある電圧階級の母線系統が細長いものとなっても、異種
電圧階級の母線系統も同様に細長い配置となるので、こ
れら系統を複数並置して変電所を構成することにより、
変電所の全体的な形態はあるまとまりのある形、即ち平
面的に見てより正方形に近い形になるためである。The main reason why this type of bus bar arrangement was used in the past was as follows.
Even if the busbar system of a certain voltage class is long and narrow, the busbar systems of different voltage classes will also be long and narrow, so by configuring a substation by arranging multiple of these systems side by side,
This is because the overall shape of the substation is a certain cohesive shape, that is, a shape that is closer to a square when viewed from above.

しかしこのように必らずしも異種電圧階級の母線系統が
複数系統存在するとは限らず、単独系統の母線配置によ
り、効果的な形態に母線配置できることが望ましい。However, it is not always the case that there are a plurality of busbar systems of different voltage classes, and it is desirable to be able to arrange the busbars in an effective manner by arranging the busbars of a single system.

また、これを解決するために、二重母線を第２図のよう
に折曲することも考えられたが、このように単に折曲し
ただけでは、破線で囲んだ部分がテ゛ツドスペースとな
ってしまい、スペースの有効活用がはかれない。Also, in order to solve this problem, it was considered to bend the double busbar as shown in Figure 2, but if the double busbar was simply bent like this, the area surrounded by the broken line would become a tied space. , space cannot be used effectively.

図では単線で示しであるが、実際には各母線毎に、三相
分の導体が平行配置しであるため、デッドスペースはか
なり大きなものになってしまう。Although shown as a single line in the figure, in reality, conductors for three phases are arranged in parallel for each bus bar, so the dead space becomes quite large.

本考案の目的は、二重母線４ブスタイ方式を採用するに
当り、各母線相互を効果的に配置構成することにより、
デッドスペースを生じることなく変電所の占有面積を有
効活用できしかも用地確保をも容易にすることができる
二重母線装置を提供することにある。The purpose of this invention is to effectively arrange and configure each bus bar when adopting a double bus 4 bus tie system.
To provide a double busbar device capable of effectively utilizing the occupied area of a substation without creating dead space, and also making it easy to secure land.

以上本考案の一実施例を図面を参照して説明する。An embodiment of the present invention will be described above with reference to the drawings.

尚、本考案による二重母線装置は前記第１図の母線構成
をより効果的に配置したものであり、第１図と対応する
部分には同一符号を付す。The double busbar device according to the present invention is a more effective arrangement of the busbar configuration shown in FIG. 1, and parts corresponding to those in FIG. 1 are designated by the same reference numerals.

。As shown in Fig. 3, in both systems A and B, the bus conductor 11a,
llb, 12a, 12b are formed into a U shape via a disconnector 13.14 and a busbar connection breaker 15a or 15b, and between the legs A and B of each U shape, either one of the opposite side The leg sides B of the busbar connection breaker 15 are positioned so that they are substantially parallel to each other, and
The respective bottom sides C having a and 15b are arranged so as to face the end of the one leg side B on the other side.

12b(7) Connect the end of the leg side A located on the outside and the bottom side C of the other side as shown in the figure by a disconnector 13.14 and a busbar connection breaker 15C or 15d, respectively, It has a double bus bar 4 bus tie configuration.

尚、各送受電回線１８は甲乙側母線系統の導体間から図

して所要回線数引出される。The required number of power transmission/reception lines 18 are drawn out from between the conductors of the bus system on the A/B side via disconnectors 13 and 14 and a branch breaker 16 as shown in the figure.

上記のように構成すれば、送受電回線１８が多くても、

用でき、用地確保の面からも遥かに有利である。With the above configuration, even if there are many power transmission and reception lines 18,
Rather than having an extremely long and narrow shape as shown in Figure 1, the substation has a more practical rectangular shape, which allows for effective use of land and is far more advantageous in terms of securing land.

Each set can be arranged linearly without causing any inconvenience to the conductor routing.

更に各送受電回線１８も両Ｕ形母線導体の両側方に整然

はない。Furthermore, each power transmission/reception line 18 is also neatly drawn out to both sides of both U-shaped busbar conductors, so that maintenance and inspection work on these lines is not impaired.

とはならず、より実際的な平面長方形の形態にすること
ができ、用地を有効活用でき、また、用地確保の面から
も従来の形態に比べはるかに容易となる。As described above, according to the present invention, when configuring a substation using the double bus 4 bus tie system, the bus conductors of both systems A and B are shaped into a U shape, and one of the legs of this U shape is However, since they are arranged so that they are located almost parallel to each other between the legs of the mating bus conductor, even if there are many power transmission/reception lines and a single-system substation, it will not take on an extremely long and slender form as in the past. Instead, it can be made into a more practical rectangular shape, making effective use of land, and it is much easier to secure land than with conventional shapes.

すなわち、一般に工場や変電所用の敷地として極端に細

確保することは実際問題として困難である。In other words, in general, there are almost no extremely long and narrow sites for factories or substations, except in special cases, and they are usually rectangular in shape, and it is difficult in practice to secure such long and narrow sites as sites for substations. .

また長方形状の工場敷地の一部に細長い変電所用地を確

このようなことから従来の細長い形態では、その用地を
確保するのが難しかったが、本考案によれば、変電所用
地が実際的な長方形となるため、」二連のような問題は
生じなくなり、用地確保が容易になる。For this reason, it was difficult to secure a site for the conventional elongated substation, but according to this invention, the site for the substation becomes a practical rectangle, so problems such as "double stations" no longer occur. , it becomes easier to secure land.
