Description

【0001】
【発明の属する技術分野】
本発明は電力の送配電や受配電に用いられるガス絶縁開閉装置に関する。
【0002】
【従来の技術】
【特許文献1】特開平10―75513号公報
一般に、ガス絶縁開閉装置は電力の送配電や受配電を行うために電力系統の開閉に多く採用されている。ガス絶縁開閉装置は電力系統から通常2回線を引込み、主母線は電力の安定供給のため2重母線方式にしている。主母線は相分離配置あるいは3相一括配置するようにしている。
【0003】
ガス絶縁開閉装置は電力系統のケーブルがケーブルヘッドを介してケーブル容器に引込れ遮断器を介して主母線に接続される。遮断器の電力系統側(以後、線路側と称する)と主母線側(以後、母線側と称する)に断路器と接地開閉器を設けている。主母線が2重母線の場合には、遮断器の母線側には両主母線毎に断路器と接地開閉器が設けられる。
【0004】
このように遮断器の線路側と母線側には遮断器の保守点検のために断路器と接地開閉器が設けられる。この断路器と接地開閉器を1台の3点位置形開閉器で構成するようにしている。3点位置形開閉器は3点位置形接地装置付断路器と呼称されているが、以後、本明細書では3位置形断路器と称する。3位置形断路器を用いると、断路器と接地開閉器間のインタ−ロックを採る必要がなくシステム簡素化、誤操作防止など信頼性を高めることができる。
【0005】
断路器と接地開閉器を1台の3位置形断路器で構成することは、例えば、上記特許文献1に記載されている。従来、遮断器の線路側の3位置形断路器は円筒形状のケーブル容器に垂直方向(高さ方向)に配置し、また、母線側の3位置形断路器を母線容器の分岐管内に配置している。
【0006】
【発明が解決しようとする課題】
従来技術は、遮断器線路側の3位置形断路器をケーブル容器内に、ケーブル容器軸線上に垂直方向(高さ方向)に配置しており、ケーブル容器の高さ方向の長さが大きくなる。例えば、300mm〜500mm程度大きくなる。ガス絶縁開閉装置を建屋の屋内に設置しようとすると建屋を高くしなければならず建屋を含むコストが大になるという問題点を有する。また、天井クレーンの高さにも制限があることからケーブル容器の高さを小さくすることが強く望まれている。
【0007】
本発明の目的はケーブル容器の高さを小さくしてガス絶縁開閉装置を設置する建屋を含むコスト低減を図ることができるガス絶縁開閉装置を提供することにある。
【0008】
【課題を解決するための手段】
本発明の特徴とするところはケーブル容器に遮断器容器と連結する水平分岐管を形成し、このケーブル容器水平分岐管内に遮断器線路側の3位置形断路器を配置するようにしたことにある。
【0009】
本発明はケーブル容器に形成され遮断器容器と連結する水平分岐管内に遮断器線路側の3位置形断路器を配置しているのでケーブル容器の高さを小さくでき、ガス絶縁開閉装置を設置する建屋を含むコスト低減を図ることができる。

[Prior art]
[Patent Document 1] Japanese Patent Application Laid-Open No. H10-75513 Generally, a gas insulated switchgear is often used for opening and closing an electric power system in order to transmit and receive and distribute electric power. The gas insulated switchgear usually draws two lines from the power system, and the main bus is of a double bus type for stable power supply. The main bus is arranged in a phase-separated arrangement or a three-phase arrangement.

In the gas insulated switchgear, the cable of the power system is led into the cable container via the cable head and connected to the main bus via the circuit breaker. A disconnector and a grounding switch are provided on the power system side (hereinafter, referred to as a line side) and the main bus side (hereinafter, referred to as a bus side) of the circuit breaker. When the main bus is a double bus, a disconnector and a grounding switch are provided for each main bus on the bus side of the circuit breaker.

As described above, the disconnector and the earthing switch are provided on the line side and the bus side of the circuit breaker for maintenance and inspection of the circuit breaker. The disconnecting switch and the grounding switch are constituted by one three-point position switch. The three-point switch is referred to as a three-position switch with a grounding device, but is hereinafter referred to as a three-position switch in the present specification. When a three-position disconnector is used, it is not necessary to take an interlock between the disconnector and the grounding switch, and the reliability can be improved, such as simplification of the system and prevention of erroneous operation.

For example, it becomes larger by about 300 mm to 500 mm. If the gas insulated switchgear is to be installed inside a building, the building must be raised and the cost including the building increases. In addition, since the height of the overhead crane is limited, it is strongly desired to reduce the height of the cable container.
