【考案の詳細な説明】 本考案は屋内外の気中絶縁変電所に於ける二重母線４ブ
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１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 power is transmitted and received using a double-bus single 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、図示のように甲母線導体１１と乙母線導体１２と
をほぼ平行に配置し、両回線導体１１．１２間を断路器
１３．１４を介して母線連絡しゃ断器１５により連絡す
ると共に、両回線導体１１．１２から断路器１３．１４
及び分岐しゃ断器１６を介して送受電回路１８を引き出
すように構成している。That is, as shown in the figure, the first bus line conductor 11 and the second bus line conductor 12 are arranged almost in parallel, and both line conductors 11.12 are connected by a bus line communication breaker 15 via a disconnector 13.14, and both line conductors 11. Line conductor 11.12 to disconnector 13.14
The power transmitting/receiving circuit 18 is connected via the branch circuit breaker 16.

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６６ ＫＶの屋内建家式変電所に於て、第２図で
示すように、送受電回線１８を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を必要とし、面積は１２００ｍ２となる。For example, in a 66 KV indoor substation, as shown in Figure 2, when 16 power transmission/reception lines 18 are drawn out, the approximate dimensions are approximately 100 m in the length direction of the busbar and approximately 12 m in the width direction. The area is 1200m2.

すなわち、第２図の寸法関係をより詳細に説明すると、
母線の長さ方向に沿う各しゃ断器１６相互間の間隔は約
５ｍである。That is, to explain the dimensional relationship in FIG. 2 in more detail,
The distance between the circuit breakers 16 along the length of the busbar is about 5 m.

母線１１ａ、１２ａ間及び１１ｂ、１２ｂ間には、母線
の長さ方向に沿ってそれぞれ９台のしゃ断器が配置して
あり、この間の距離は片側約４５ｍである。Between the busbars 11a and 12a and between 11b and 12b, nine circuit breakers are arranged along the length direction of the busbars, and the distance between them is about 45 m on one side.

また中間部に位置する母線連絡しゃ断器、１５ ａ 、
１５ ｂの配置に要する母線長さ方向に沿う距離は、両
側の断路器１３．１４を含んで約１０ｍである。There is also a busbar connection breaker located in the middle, 15a,
The distance along the length direction of the bus bar required for arranging 15b is about 10 m including the disconnectors 13 and 14 on both sides.

従って変電所の母線長さ方向の寸法は、４５Ｘ２＋１０
＝１００ｍとなる。Therefore, the dimension of the substation in the busbar length direction is 45X2+10
=100m.

また、母線と直交する幅方向については、母線１１．１
．１１ ｂと、１２ ａ 、１２ ｂとの２組が並行に
配置されるが、これら母線はそれぞれ三相用であり、計
６本の母線導体が平行に走ることになる。In addition, regarding the width direction perpendicular to the generatrix, generatrix 11.1
．． Two sets of busbars 11b, 12a, and 12b are arranged in parallel, but each of these busbars is for three phases, and a total of six busbar conductors run in parallel.

そして、これら６本の母線導体の最外側間及び、機器配
置上等の間隔を含んだ長さが約１２ｍである。The length including the outermost distance between these six busbar conductors and intervals for equipment arrangement is approximately 12 m.

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が細長いものとなっても、異種電圧
階級の母線も同様に細長い配置となるので、これらを複
数系統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 busbars of a certain voltage class are long and thin, the busbars of different voltage classes will also be long and thin, so by arranging multiple systems in parallel to form a substation, the overall form of the substation can be improved. This is because it becomes a certain coherent 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.

このような要望に対処するため、第１図で示す二重母線
１ブスタイ方式のものについては、いずれかの母線導体
、例えば甲母線導体１１をＵ形に形成し、他方の乙母線
導体１２を、前記甲母線導体１１のＵ形の両脚辺間に配
置する構成が考えられた。In order to meet such demands, in the double bus single bus tie system shown in FIG. , a configuration was considered in which the conductor 11 is arranged between both legs of the U-shape.

このような配置構成にすると、第１図で示す細長い形状
に比べ、面積を９０％程度に縮少でき、かつ母線量も概
略３／４に減少させることができ、経済的効果は大きい
。With this arrangement, compared to the elongated shape shown in FIG. 1, the area can be reduced to about 90%, and the amount of busbars can also be reduced to about 3/4, resulting in a large economic effect.

しかしこのような母線構成は、前記二重母線１ブスタイ
方式に採用すると上述のような効果を生じるが、第２図
で示す二重母線４ブスタイ方式にそのまま適用すると、
第３図のような導体及び機器配置になってしま７い、母
線の利用率が悪くなるばかりか、設置面積の点でも不利
になり、上述のような効果を発揮することができない。However, when such a busbar configuration is adopted in the double busbar one bus tie system, it produces the effects described above, but when applied as is to the double busbar four bustie system shown in FIG.
If the conductors and equipment are arranged as shown in FIG. 3, the busbar utilization rate will be poor, and the installation area will also be disadvantageous, making it impossible to achieve the above-mentioned effects.

一般にこのような二重母線４ブスタイ方式を必要とする
変電所は比較的大規模、大容量の変電所であり、土地入
手難などの見地からより縮少された変電所にする必要が
ある。Generally, substations that require such a double busbar four-bus tie system are relatively large-scale, large-capacity substations, and from the viewpoint of land acquisition difficulties, it is necessary to make the substations smaller.

また屋内変電所を構成する場合は変電所の面積が即建家
価格に反映するので、この面からも面積を効果的に利用
できる配置構成が必要となる。Furthermore, when configuring an indoor substation, the area of the substation will be reflected in the price of the house immediately built, so from this point of view as well, a layout configuration that allows effective use of the area is required.

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、
変電所の占有面積を縮少し、かつ母線使用量をも減少さ
せ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.
It is an object of the present invention to provide a double busbar device capable of reducing the occupied area of a substation and also reducing the amount of busbars used.

第４図で示す如く、甲、８両母線系統のいずれが一方の
母線導体、例えば甲系統側母線導体１１ａ。As shown in FIG. 4, each of the A and 8 bus systems has one bus conductor, for example, the bus conductor 11a on the A system side.

１１ ｂをＵ形に形成し、このＵ形の各脚辺部１１ ａ

and the busbar conductors 12a and 12b on the O system side, respectively, using disconnectors 13, 14 and busbar connection breaker 1.
5a, 15b, 15C, and 15d are connected as shown in the figure, forming a double bus 4 bus tie configuration.

尚、各送受電回線１８は甲、８両母線系統の導体間から
図示のように断路器１３．１４及び分岐しゃ断器１６を
介して引出される。In addition, each power transmission/reception line 18 is drawn out from between the conductors of the A and 8 bus systems via disconnectors 13 and 14 and a branch breaker 16 as shown in the figure.

上記のように構成した場合の占有面積を同数の引出回線
を有する第２図との比較で説明すると、第２図の場合、
６６ ＫＶ屋屋内宗家式変電所標準寸法で配置すると、
長さ方向で約１００ｍ、幅方向で約１２ｍとなり、占有
面積１２００ｍ２となるか゛、第４図で示す実施例では
、長さ方向で約１／４の約３０ｍ、これの直角方向で約
３６ｍとなり、占有面積は１０８０ｍ２と第２図の場合
の９０％にすることか゛できる。To explain the occupied area when configured as above by comparing it with Figure 2 which has the same number of outgoing lines, in the case of Figure 2,
66 KV shop indoor Soke type substation When arranged with standard dimensions,
The length is about 100 m, the width is about 12 m, and the occupied area is 1200 m2. In the example shown in Fig. 4, the length is about 1/4, or about 30 m, and the perpendicular direction is about 36 m. The occupied area can be reduced to 1080 m2, which is 90% of the case shown in FIG.

この寸法関係をより詳細に説明する。This dimensional relationship will be explained in more detail.

第２図の場合と同様に、母線長さ方向に沿うしゃ断器１
６間の距離を約５ｍとすると、母線１２ ａ 、１２
ｂの長さは約２０ｍとなる。As in the case of Fig. 2, the breaker 1 along the length direction of the bus bar
If the distance between 6 is about 5 m, the bus lines 12 a, 12
The length of b is approximately 20 m.

また母線１１ ａ Ａ、１１ ａ Ｂ、１１ ｂＢ、１
１ｂＡの図示横方向の長さは、Ｕターン分を含むので、
若干長くなり、３０ｍ弱となる。Also, busbars 11 a A, 11 a B, 11 bB, 1
The illustrated lateral length of 1bA includes the U-turn, so
It is slightly longer, at just under 30m.

次に母線と直交する幅方向につき説明する。Next, the width direction perpendicular to the generatrix will be explained.

第２図の場合で説明したが、２組の母線すなわち、各３
組分計６本の導体が平行に配置された場合の幅寸法は１

１ａＡ１２ ａ間及び１２ ａ −１１ａ Ｂ間の寸法
１２ｍに対し共通であり、互いにラップする。As explained in the case of Fig. 2, two sets of bus lines, each 3
When a total of 6 conductors are arranged in parallel, the width dimension is 1
2m, but for example, as shown in Fig. 5, three sets of busbars 11a
When A, 12a, 11a and B are arranged in parallel, the dimensions of the middle generatrix 12a are set for each set, that is, 1
It is common to the dimensions 12 m between 1aA and 12a and between 12a and 11aB, and overlaps each other.

このラップ分は導体間隔や機器配置寸法等の関係から約
６ｍとなる。The length of this wrap is approximately 6 m due to the conductor spacing, equipment arrangement dimensions, etc.

第４図の配置構成は６組の母線が平行に配置しであるの
で、前記幅方向は３６ｍになる。In the arrangement shown in FIG. 4, six sets of generatrix lines are arranged in parallel, so the width in the width direction is 36 m.

すなわち母線と直交する方向の長さは約３６ｍとなる。That is, the length in the direction perpendicular to the generatrix is approximately 36 m.

この長さ寸法は機器の配置等により若干変化するが、基
本的にはこのように設定できる。This length dimension varies slightly depending on the arrangement of the equipment, etc., but basically it can be set as shown above.

更に多量の送受電回線１８を有する場合例えば第２図及
び第４図の状態から更に送受電回線１８が１６回線増え
た場合は、第２図に於ては母線の長さ方向が約１９０
ｍ、幅方向は１２ｍで、占有面積は２２８０ｍ２となる
が、第４図に於ては、母線長さ方向は５０ｍ、これと直
角方向は３６ｍで占有面積は１８００ｍ２となり、第２
図の方式による場合に対して面積縮少率は７９％となる
。In the case where there is an even larger number of power transmitting and receiving lines 18, for example, if the number of power transmitting and receiving lines 18 is increased by 16 from the state shown in FIGS. 2 and 4, the length direction of the bus line in FIG. 2 is about 190.
m, the width direction is 12 m, and the occupied area is 2280 m2, but in Figure 4, the generatrix length direction is 50 m, and the direction perpendicular to this is 36 m, and the occupied area is 1800 m2, and the second
The area reduction rate is 79% compared to the case using the method shown in the figure.

即ち回線数が多くなる程（大規模変電所柱）面積縮少率
は大となる。In other words, the larger the number of lines (large-scale substation poles), the larger the area reduction rate.

また母線導体量についても、乙系統側母線導体１２ ａ
、１２ ｂは共用部分が増えることにより短縮され、
他の増加分を考慮に入れても、導体長、及び各部の電流
容量等を総合的に見れば全体として増えることはなく、
むしろ減少する。Also, regarding the amount of bus conductors, the bus conductor 12 a on the O system side
, 12b is shortened by increasing the number of shared parts,
Even if other increases are taken into account, if you look at the conductor length and the current capacity of each part comprehensively, there will be no increase as a whole.
In fact, it will decrease.

この寸法関係をより詳細に説明すると、前述のように、
母線１２ ａ 、１２ ｂの長さは約２０ｍである。To explain this dimensional relationship in more detail, as mentioned above,
The length of the bus bars 12a and 12b is approximately 20 m.

また母線１１ ａＡ、１１ ａＢ、１１ ｂＢ、１１
ｂＡノ図示横方向の長さは３０ｍ弱である。Also busbars 11 aA, 11 aB, 11 bB, 11
The length of bA in the horizontal direction shown in the drawing is a little less than 30 m.

そしてＵターンの底部は約１８ｍである。The bottom of the U-turn is about 18m.

従ってこれらの全体としての長さは、（２０ｘ２）＋（
３０ｘ４）＋（１８Ｘ２）＝１９６ｍとなり、第２図の
約２００ｍと比べ、むしろ減少することか゛わかる。Therefore, their overall length is (20x2) + (
30 x 4) + (18

また母線の利用率について見ると、第２図の構成に比べ
差はないが、第２図の二重母線・４ブスタイ方式を従来
のｂ形装置にそのまま適用した第３図の場合のように、
利用率が極端に悪くなることはない。In addition, when looking at the utilization rate of the busbars, there is no difference compared to the configuration shown in Figure 2, but as in the case of Figure 3, where the double busbar/four bus tie system in Figure 2 is applied as is to the conventional B-type equipment. ,
The utilization rate will not be extremely bad.

更に機器配置上も、４組の母線連絡機器のうち、３台の

き、導体の引廻しに何ら不都合を与えない。Furthermore, in terms of equipment arrangement, among the four sets of busbar communication devices, three busbar communication breakers 15C, 15b, and 15d can be arranged linearly together with the respective disconnectors 13 and 14, making it possible to route the conductors. will not cause any inconvenience.

また各送受電回線１８も両Ｕ形母線導体１１ ａ、１１
ｂの両側方に整然と引出され、これらの保守点検作業
等が損なわれることはない。Each power transmission/reception line 18 also has both U-shaped bus conductors 11 a, 11
They are pulled out in an orderly manner on both sides of b, so that these maintenance and inspection operations will not be impaired.

尚、上記実施例では、両Ｕ形母線導体１１ａ、１１ｂ間

連結しても構わない。In the above embodiment, the connection between the U-shaped bus conductors 11a and 11b is made between the U-shaped bottoms 113C and 11bC, but the present invention is not limited to this.
The connection may be made at any position, such as by connecting the ends of aB and 11 bB.

これは他の母線間連結部についても同様である。This also applies to other busbar connections.

また母線量をも減少させることができる。As described above, according to the present invention, when configuring a substation using the double bus 4 bus tie system, the bus conductor of one system is shaped into a U shape and combined with the bus conductor of the other system. Since it is now possible to configure the layout, even in large-scale, large-capacity substations that draw out many power transmission and reception lines, the busbars do not have to be long in the length direction as in the past, but can be configured in a more general square shape. All you have to do is secure a similar occupied area, and by adopting this form, the actual occupied area can be reduced.
It is also possible to reduce the amount of bus radiation.
