Abstract

<P>PROBLEM TO BE SOLVED: To reduce the floor area of gas-insulated switchgear in which three switch units are disposed. <P>SOLUTION: The cylindrical tanks of phase A, phase B and phase C of the switch units 1-1, 1-2, 1-3 are provided at one end or both ends with a branch pipe perpendicular to the directions of the axes of the cylinders. The phase A, phase B and phase C of the switch units are disposed in parallel with the ground 9 so that the directions of the axes of the cylinders of the cylindrical tanks are parallel with one another. The switch units are stacked up through legs that mechanically connect upper and lower switch units perpendicularly to the ground so that the same phases of the switch units overlap one another. Two branch pipes of the same phase of the switch units are connected with a linking busbar installed perpendicularly to the ground. Main busbars of the respective phases are connected to the end faces of the cylindrical tanks in the directions of the axes of the cylinders in the phase A, phase B and phase C of the cylindrical tanks on the side of the switch units where the branch pipe is not provided. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

本発明は、２重母線方式の母線及び送電線路が、架空線またはケーブルで構成される変電設備で、開閉装置部分が１−１／２遮断方式のガス絶縁開閉装置に関するものである。   The present invention relates to a gas-insulated switchgear in which a double busbar bus and a transmission line are substations in which an overhead line or a cable is used, and the switchgear portion is a 1-1 / 2 cut-off system.

従来の技術では、例えば、特許文献１、特許文献２、特許文献３、特許文献４、特許文献５のように、３台の遮断器を遮断器軸方向に平面状に直列に配置する場合、奥行き方向の長さが長くなるために、据え付け面積が広くなるという問題があった。   In the conventional technology, for example, as in Patent Document 1, Patent Document 2, Patent Document 3, Patent Document 4, and Patent Document 5, when three circuit breakers are arranged in series in the circuit breaker axial direction, Since the length in the depth direction is long, there is a problem that the installation area is widened.

また、たとえば、特許文献５、特許文献６のように、３台の遮断器を折り曲げて平面状に配置し、接続した場合でも、開閉ユニットの軸方向と垂直方向の長さが大きくなるために、据え付け面積が広くなるという問題があった。   In addition, for example, as in Patent Document 5 and Patent Document 6, even when three circuit breakers are bent and arranged in a planar shape and connected, the length in the direction perpendicular to the axial direction of the switching unit increases. There was a problem that the installation area was widened.

Part or equivalent part is shown.

本実施の形態３では、枝管６と地面と垂直に配したつなぎ母線４とをベローズ１７を介して接続するようにしている。   In the third embodiment, the branch pipe 6 and the connecting bus 4 arranged perpendicular to the ground are connected via the bellows 17.

また、開閉ユニット１−１の各相と開閉ユニット１−２の各相との上下間を機械的に接続する脚部７、及び開閉ユニット１−２の各相と開閉ユニット１−３の各相との上下間を機械的に接続する脚部７を少なくとも２つに分割できるようにしている。   Further, the leg 7 for mechanically connecting the upper and lower sides of each phase of the switching unit 1-1 and each phase of the switching unit 1-2, and each phase of the switching unit 1-2 and each of the switching unit 1-3 The leg portion 7 that mechanically connects the upper and lower sides with the phase can be divided into at least two.

このような構成とすることによって、故障時における開閉ユニットの交換における作業性が向上する。具体的には、例えば、図９における開閉ユニットＡ相の１−２−Ａに故障が発生し、開閉ユニットＡ相の１−２−Ａの交換が必要となった場合、開閉ユニット１−１−Ａと開閉ユニット１−２−Ａ及び開閉ユニット１−２−Ａと開閉ユニット１−３−Ａとの上下間を機械的に接続する脚部７を分割し、開閉ユニット１−１−Ａを地面で支持する別の脚部（図示せず）で支持し、さらに、開閉ユニット１−２−Ａと地面と垂直に配したつなぎ母線４との間のベローズ１７を地面と垂直に配したつなぎ母線４とベローズ１７との接続部で切り離し、ベローズ１７を圧縮して地面と垂直に配したつなぎ母線４内の母線とベローズ１７内の母線との接続部とを切り離すことにより開閉ユニット１−２−Ａを円筒軸方向に引き出すことができる。また、逆の手順で新たな開閉ユニット１−２−Ａを据え付けることができる。   By adopting such a configuration, workability in replacing the switching unit at the time of failure is improved. Specifically, for example, when a failure occurs in the switching unit A-phase 1-2-A in FIG. 9 and the switching unit A-phase 1-2-A needs to be replaced, the switching unit 1-1 -A and the opening / closing unit 1-2-A, and the leg 7 that mechanically connects the upper and lower sides of the opening / closing unit 1-2-A and the opening-and-closing unit 1-3-A is divided into the opening-and-closing unit 1-1-A. And a bellows 17 between the open / close unit 1-2-A and the connecting bus 4 arranged perpendicular to the ground is arranged perpendicular to the ground. Opening and closing unit 1- is disconnected by disconnecting at the connecting portion between the connecting bus 4 and the bellows 17, and compressing the bellows 17 and disconnecting the connecting portion between the connecting bus 4 in the connecting bus 4 arranged perpendicular to the ground and the connecting rod within the bellows 17. 2-A can be pulled out in the cylindrical axis direction. Further, a new opening / closing unit 1-2-A can be installed in the reverse procedure.

以上のように、本実施の形態３によれば、故障時における開閉ユニットの交換の作業性が向上する。   As described above, according to the third embodiment, the workability of replacing the opening / closing unit at the time of failure is improved.
