Description

この発明は、電力の送配電及び受電設備に用いられる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 used for power transmission / distribution and power reception facilities.

従来のガス絶縁開閉装置においては、絶縁ガスを内部に封入して上下方向に配置された３つの容器が、それぞれの容器間を絶縁スペーサでガス区分するとともに、中央の容器内に配設された水平母線を挟んで、水平母線の上下に前記水平母線に接続された２台の断路器を配置するとともに、上下の容器にはそれぞれ前記断路器に接続された遮断器を収納しており、前記上下の容器の後部壁面を貫通して前記遮断器に接続されたケーブル接続部を設けている（例えば、特許文献１を参照）。 In the conventional gas-insulated switchgear, three containers arranged in an up-and-down direction with an insulating gas sealed inside are divided into gas by insulating spacers between the containers and disposed in the central container. While placing two disconnectors connected to the horizontal bus above and below the horizontal bus across the horizontal bus, the upper and lower containers each contain a circuit breaker connected to the disconnector, A cable connecting portion that penetrates the rear wall surfaces of the upper and lower containers and is connected to the circuit breaker is provided (for example, see Patent Document 1).

特開２００６−１０９６９７号（第３−５頁、図６）JP 2006-109697 A (page 3-5, FIG. 6)

従来のガス絶縁開閉装置では、中央の容器内のほぼ中央部に水平母線とこの水平母線の上下に２台の回動ブレード形の断路器を配置しており、前記各断路器に向けて前記水平母線から分岐して配置した端子と接離する前記断路器の可動ブレードを、前記水平母線の上下から前記水平母線の前記各端子に向けて配置したので、前記各断路器の可動ブレードと水平母線から分岐した前記端子との間、すなわち水平母線の上下部（２箇所）に所定値以上の耐電圧性能を確保できる断路距離（スペース）を設ける必要がある。
このため、水平母線の上部と下部のそれぞれに、所定値以上の断路距離を確保するため、中央容器の高さ方向の寸法が大きくなるという問題点があった。 In a conventional gas-insulated switchgear, a horizontal bus bar is arranged at a substantially central portion in a central container, and two rotating blade-type disconnectors are arranged above and below the horizontal bus bar. Since the movable blades of the disconnector that contacts and separates from the terminals that are branched from the horizontal bus are arranged from the upper and lower sides of the horizontal bus toward the terminals of the horizontal bus, the movable blades of the disconnectors It is necessary to provide a disconnect distance (space) that can ensure a withstand voltage performance of a predetermined value or more between the terminals branched from the bus, that is, at the upper and lower portions (two locations) of the horizontal bus.
For this reason, in order to ensure the disconnection distance more than predetermined value in each of the upper part and lower part of a horizontal bus line, there existed a problem that the dimension of the height direction of a center container became large.

この発明は、上述のような課題を解決するためになされたもので、第一の目的は、容器の高さ方向の寸法を縮小化するものである。   This invention was made in order to solve the above-mentioned subject, and the 1st objective is to reduce the dimension of the height direction of a container.

また、第２の目的は、容器の奥行き方向の寸法を縮小化するものである。   The second object is to reduce the dimension of the container in the depth direction.

この発明に係るガス絶縁開閉装置は、容器の高さ方向のほぼ中央部に２回路分の三位置断路器を上下に並置し、この三位置断路器の後部に水平母線を配置して三位置断路器に接続するとともに、容器内の２つの三位置断路器の上方と下方にそれぞれ遮断器ユニットを配置して三位置断路器の可動接触子と遮断器の一方の端子を接続し、遮断器の他方の端子を前記密閉容器の後部壁の貫通部に装着したケーブル接続ブッシングに接続し、ケーブル接続ブッシングにケーブルを接続したものである。   In the gas insulated switchgear according to the present invention, a three-position disconnector for two circuits is juxtaposed vertically at a substantially central portion in the height direction of the container, and a horizontal bus bar is arranged at the rear of the three-position disconnector. Connect to the disconnector and place the circuit breaker units above and below the two three-position disconnectors in the container to connect the movable contact of the three-position disconnector and one terminal of the circuit breaker. The other terminal is connected to a cable connection bushing attached to a through-hole in the rear wall of the sealed container, and a cable is connected to the cable connection bushing.

水平母線を三位置断路器より後方に配置することにより、上下２つの三位置断路器の各可動接触子間の断路距離（１箇所）だけを確保すればよくなるため、上下方向の寸法は、水平母線の高さ寸法及び上下２つの三位置断路器の各可動接触子と水平母線間の断路距離（２箇所）のうち一方の断路距離（１箇所）が不要になり、容器の高さ方向の寸法を縮小化することができる。 By arranging the horizontal bus behind the three-position disconnector, it is only necessary to secure a disconnection distance (one place) between the movable contacts of the upper and lower three-position disconnectors. The disconnection distance (one location) of the height of the busbar and the disconnection distance (2 locations) between each movable contact and the horizontal busbar of the two upper and lower three-position disconnectors is no longer required. The dimensions can be reduced.

さらに、水平母線を三位置断路器の後方の容器外とすることにより、容器の奥行き方向の寸法も縮小化することができる。 Furthermore, the dimension of the container in the depth direction can be reduced by making the horizontal bus outside the container behind the three-position disconnector.

In the first embodiment, the three-position disconnectors 4 and 5 are “in-position” in which the movable contacts 4 c and 5 c are in contact with the in-terminal 6, and “in-ground position in which the movable contacts 4 c and 5 c are in contact with the ground terminal 7.

三位置断路器４、５は、回動軸４b、５bを支点とした回動形の可動接触子４ｃ、５ｃを用いたものについて説明したが、上記の他に、可動接触子がガス絶縁開閉装置の前後方向に直線動作し、入端子、接地端子とそれぞれ接触する構成でもよい。直線動作形の方が、可動接触子が回動運動をしない分、高さ方向の寸法を小さくすることができる。 The three-position disconnectors 4 and 5 have been described using the rotary movable contacts 4c and 5c with the rotary shafts 4b and 5b as fulcrums. A configuration in which the device linearly moves in the front-rear direction of the device and contacts the incoming terminal and the ground terminal may be employed. In the linear motion type, the dimension in the height direction can be reduced because the movable contact does not rotate.

また、絶縁ガスを封入した容器１は、３つの容器（１ｃ、１ｄ、１e）がそれぞれ独立した構成にするよりも、１つの容器１内を仕切１ａ、１ｂで仕切ることで３つの空間を形成する構成の方が簡単な構成となり、製作が容易となる。 Further, the container 1 filled with the insulating gas forms three spaces by dividing the inside of one container 1 with the partitions 1a and 1b, rather than making the three containers (1c, 1d, and 1e) independent of each other. This configuration is simpler and easier to manufacture.

実施の形態２．
なお、実施の形態１では、水平母線２を容器内部に配置したが、図３、図４に示すように、容器１の外側である容器後部を貫通して母線接続用ブッシング２２を設け、水平母線２と入端子６を前期母線接続用ブッシング２２を介して接続してもよい。このような構成により、中央容器１ｄ内に水平母線２を収納するスペースを確保することが不要となり、容器１の奥行き寸法をさらに小さくすることができる。 Embodiment 2. FIG.
In the first embodiment, the horizontal bus 2 is arranged inside the container. However, as shown in FIGS. 3 and 4, a bus connecting bushing 22 is provided through the rear part of the container that is outside the container 1, You may connect the bus-line 2 and the incoming terminal 6 via the bus-line connection bushing 22 for the previous term. With such a configuration, it is not necessary to secure a space for storing the horizontal bus 2 in the central container 1d, and the depth dimension of the container 1 can be further reduced.

また、図３、図４に示すように、水平母線２の各相導体２ａを上下方向に並置したので、ガス絶縁開閉装置の奥行き方向の寸法を小さくすることができ、ガス絶縁装置をコンパクトに構成できる。 Also, as shown in FIGS. 3 and 4, since the phase conductors 2a of the horizontal bus 2 are juxtaposed in the vertical direction, the dimension in the depth direction of the gas insulated switchgear can be reduced, and the gas insulated device can be made compact. Can be configured.
