電盤に関するものである。[Detailed Description of the Invention] [Technical Field of the Invention] The present invention is applicable to filling an airtight container with insulating gas in a factory instead of on-site, and to simplify the installation of a closed switchboard on-site. The present invention relates to a useful insulating gas-filled closed switchboard.
［発明の技術的背景とその問題点］
一般に、閉鎖配電盤内には遮断器や断路器等の開閉装置

機器が収容されＣいる。[Technical Background of the Invention and Problems Therewith] Generally, a closed switchboard houses electrical equipment such as a switchboard equipped with switching devices such as circuit breakers and disconnectors, and meters and relays.
しかして複数室の閉鎖配電盤は、第１図に示されるよう
に、各閉鎖配電盤１ａ、１ｂ、１Ｃ内に設置した逆Ｔ型
状の分岐ブッシング２ａ 、 ２ｂ 。As shown in FIG. 1, the multi-chamber closed switchboard has inverted T-shaped branch bushings 2a, 2b installed in each closed switchboard 1a, 1b, 1C.
２０間を連絡する母線３ａｂ、３ｂｃにより電気的に接
続され”でいる。20 are electrically connected by busbars 3ab and 3bc that communicate between them.
なお、母線と分岐ブッシングとの接続は、第２図に示１
ように、分岐ブッシング２の基部中心に内蔵された中間
閉鎖の筒状遮蔽電極４に、ケーブル導体５の先端に取付
けたクサビ６を圧入することによりなされている。The connection between the bus bar and the branch bushing is shown in Figure 2.
This is accomplished by press-fitting a wedge 6 attached to the tip of a cable conductor 5 into an intermediately closed cylindrical shielding electrode 4 built into the center of the base of the branch bushing 2.
図中、祠号７は導体引出棒、８はモールドストレスコー

ところで、電気機器間の導体接続部は通常露出されてお
り、このため充電部とケース間（三相の場合は異相間）
は電圧に比例しＣ絶縁距離を大きくとらな【プればなら
ない。By the way, the conductor connections between electrical devices are usually exposed, so between the live part and the case (in the case of three-phase, between different phases)
is proportional to the voltage, so the insulation distance must be kept large.
しかしながら、絶縁距離を大きくとると閉鎖配電盤等が
大型化し、所要スペースが大となる難点がある。However, if the insulation distance is large, the closed switchboard etc. will become larger and the required space will become larger.
このため、閉鎖配電盤１ａ、ｉｂ、１Ｃ内に六回素化硫
黄ガス（ＳＦｓガス）を封入したミニクラッド方式の閉
鎖配電盤が開発されているが、かかるミニクラッド方式
の閉鎖配電盤においＣは、ガス圧が高い（約２．５ｋｇ
／ｃｄ）ので閉鎖配電盤のケース壁を厚くしな【プれば
ならず、このため閉鎖配電盤が重くなり、その運搬が大
変でありまた高価となる難点があった。For this reason, a mini-clad closed switchboard has been developed in which closed switchboards 1a, ib, and 1C are filled with six-times hydrogenated sulfur gas (SFs gas). High pressure (approximately 2.5 kg
/cd), the case wall of the closed switchboard had to be thickened, which made the closed switchboard heavy, making it difficult and expensive to transport.
そこで、閉鎖配電盤内に低ガス圧（約０．５ｋｇ／ ｃ
ｄ ）のＳＦ６ガスを封入し、絶縁距離を短くして閉鎖
配電盤全体を小型化し、ひいては閉鎖配電盤の運搬を容
易にしたいわゆる低ガス圧方式の閉鎖配電盤が提案され
ている。Therefore, low gas pressure (approximately 0.5 kg/c
A so-called low gas pressure type closed switchboard has been proposed in which the closed switchboard is filled with SF6 gas and the insulation distance is shortened to make the entire closed switchboard smaller, which in turn makes it easier to transport the closed switchboard.
ところが、かかる低ガス圧方式の閉鎖配電盤においては
、閉鎖配電盤の小型化により各閉鎖配電盤間を電気的に
接続する母線の長さが必然的に短くなり、それに比例し
て母線が硬くなる傾向にある。However, in such low gas pressure type closed switchboards, as the closed switchboards become smaller, the length of the busbars that electrically connect each closed switchboard becomes shorter, and the busbars tend to become harder in proportion to this. be.
しかして、母線が硬くなるとこれを曲げることが困難に
なるので、第２図に示すような接続方法では閉鎖配電盤
間の電気的接続を容易になし得ない難点があった。However, when the busbar becomes hard, it becomes difficult to bend it, so the connection method shown in FIG. 2 has the disadvantage that electrical connection between closed switchboards cannot be easily established.
一方、上記の絶縁ガス封入閉鎖配電盤において３−
は、絶縁ガスの性質上、特性低下の要因となる塵埃の除
去とガス中の水分管理が必要なため、その組立作業は工
場内の防塵室で行なう必要がある。On the other hand, in 3- of the above-mentioned insulating gas-filled closed switchboard, due to the nature of the insulating gas, it is necessary to remove dust and control moisture in the gas, which can cause deterioration of characteristics, so the assembly work is carried out in a dust-proof room in the factory. It is necessary to do it.

ればならない。On the contrary, in the conventional closed switchboard filled with insulating gas, as shown in FIG.
1', it is necessary to connect the two busbars 9 and 9' with the lead wire 12 at the site and then fill in the insulating gas G.
従って、かかる構成の絶縁ガス封入閉鎖配電盤においで
は、母線どうしの接続時に塵埃等の侵入を防止するため
、その組立作業を簡易防塵室内で行なわなければならな
い難点がある。Therefore, the insulating gas-filled closed switchboard having such a structure has the disadvantage that the assembly work must be carried out in a simple dust-proof room in order to prevent dust from entering when connecting the busbars.
特に、現地においてガスを封入することは、−〇工場ｒ
ガスを封入し試験を行なった後にガスを抜き取って現地

ないのでガス封入作業用が２重手問になる難点がある。In particular, filling gas on-site is
After filling with gas and conducting a test, the gas must be extracted and transported to the site, and after on-site assembly, the gas must be filled again, so there is a problem in that the gas filling work becomes double work.

出されている。For this reason, as shown in FIG. 4, the inside of the airtight container 13 is divided into a plurality of chambers using spacers 14, 14' and partition covers 15, 4-15'. 16'', or a pair of busbars 19.1 whose ends are exposed to the outside of the airtight container 18.18' through an insulating spacer 17.17' as shown in FIG.
9' is connected to the lead wire 21 inside the airtight cylinder 20.
しかしながら、前者においては、現地におけるガス封入
作業が極力少なくなるものの、依然として現地における
ガス封入作業を省くことができない難点がある。However, in the former case, although the on-site gas filling work is minimized, there is still a drawback that the on-site gas filling work cannot be omitted.
また、後者においては、接続部の気密性を保持する必要
上、現地における接続部の寸法管理を厳重に行なわなけ
ればならず、このため閉鎖配電盤の据付けに長時間を要
する難点がある。In addition, in the latter case, since it is necessary to maintain the airtightness of the connection part, the dimensions of the connection part must be strictly controlled on-site, and therefore there is a drawback that it takes a long time to install the closed switchboard.
