Abstract
Description
図6に従来のタンク型のガス絶縁開閉装置を示す。各相個別に、軸線を水平方向に向けて配置された円筒状のタンク31の上方に、それぞれ2本のブッシング32,33が配置され、タンク31内に水平に遮断器本体34が配置され、遮断器本体34の固定側35が一方のブッシング32に、可動側36が他方のブッシング33に接続されているとともに、遮断器本体34は支持碍子を介してタンクの軸線方向の両端側に絶縁支持されている。可動側は、タンク一端側から絶縁ロッド37により引き出され、操作ロッド38を介して下方に回転可能な軸39に接続され、更にこの軸39は、図示しない三相連結バーによって操作機構に連結されて、駆動可能に構成されている(例えば特許文献1参照)。
ところが、特許文献1に示すような開閉装置では、円筒状のタンク内に水平に遮断器本体が配置され、さらに、タンクの軸方向の一端側に操作機構が設置されているため、水平方向に装置が大きくなり、装置の設置面積が拡大するという問題点があった。
図1は、この発明の実施の形態1による真空遮断器を示す縦断面図であり、図2は、図1の真空遮断器の全体構成とタンク内に収納される主回路機器の配置構成を示すための、上面から見た断面図である。但し、ブッシングは2点鎖線で示し、内部機器も簡略化して必要部のみ示している。図2の太矢印方向から見たものが図1である。以下、図に基づいて説明する。
電気的に接地される圧力タンク1は、後述するように上方から見ると略四角形状をしており、4辺の側壁1cを垂直にして設置される。圧力タンク1の上方には一対の開口部を有し、開口部にはフランジ1a,1bが設けられ、各フランジ1a,1bにはブッシング2a,2bが立設されている。
ブッシング2a,2bは、碍管3a,3bと、その中心に配置された中心導体4a,4bと、碍管3a,3bの上端側に気密に固定されて中心導体4a,4bを保持する端子導体5a,5bと、碍管3a,3bの下部側に固着された碍管取付部6a,6bとを備えている。碍管取付部6a,6bが圧力タンク1のフランジ1a,1bにボルト締め等で気密に締結されることで、両碍管内部および圧力タンク内が気密に保持され、内部に絶縁性ガスが封入可能となっている。
なお、両室を完全に区画して、図1の遮断器室7部分を圧力タンクとし、操作機構室8をその圧力タンクの外部に別室として構成しても良い。以下では、図1のように、遮断器室7と操作機構室8とを含めたものを圧力タンクとして説明する。
なお、操作機構10は、図では、電磁コイルの電磁力により駆動させる方式のものを例示しているが、これに限定するものではなく、他の方式のものでも良い。
一方、真空バルブ9の可動導体9bは、可撓導体14を介して、側壁1cと所定の絶縁距離を保ち垂直方向に向けて配置された可動側接続導体13bに接続される。この可動側接続導体13bの上部側にも凹状の挿入部が設けられており、この挿入部に他方のブッシング2bの中心導体4bの下端が挿入されて電気的に接続されている。両ブッシング2a,2bの下部側には電流を測定するための変流器15が設けられている。
なお、図では、本発明に必要な部分のみを示し、それ以外の機器や、支持部材等は図示及び説明を省略している。
図2において、1相分の主回路機器が収納されて、上方から見て略四角形状の圧力タンク1から構成される単相の真空遮断器21a,21b,21cは、隣接する圧力タンク1の側壁1cを対向させて一列に並べて配置され、その配列方向の一端側の外部には、単相の真空遮断器21a,21b,21cを一括制御する操作盤16が配設されている。
それぞれの圧力タンク1内に収容される真空バルブ9は、略四角形状の対角線中心からいずれかの対角方向の一方に寄せて、且つ、真空バルブ9の中心が、真空バルブ9に近い側壁からほぼ等距離になるような位置に、所定の絶縁距離を保って配置されている。
一方、可動側接続導体13bは、対角方向の他方、すなわち、真空バルブ9とは反対の対角方向に寄せて、真空バルブ9および圧力タンク1の側壁1cと十分な絶縁距離を保ち配置されている。(なお、いずれも対角側であって、対角線上である必要はない。)
また、各相の一対のブッシング2a,2bは、圧力タンク1の配列方向に対して直交する方向の対辺方向に配置されている。
真空バルブ9を、可動導体9bの駆動方向を上下方向に合わせて圧力タンク1内に配置したことにより、圧力タンク1の幅を小さくできるので、圧力タンク1の配列方向(図2の太矢印方向)に見た真空遮断器の幅寸法を小さくすることが可能になった。
また、真空バルブ9と可動側接続導体13bとを、圧力タンク1の平面から見て、平面視四角形状をした圧力タンク1の対角方向の両側に寄せて、所定の絶縁距離を保って配置したことにより、更に、上記の方向のタンク幅を小さくできる。
また、操作機構10を、真空バルブ9の下方に配置して、可動導体9bを上下方向に駆動させるようにしたので、操作機構部が圧力タンクの側壁の外側に張り出すことがなく、上記と相まって設置面積を縮小することができる。
図3は、実施の形態2による真空遮断器の全体構成とタンク内に収納される主回路機器の配置構成を示すための、上面から見た断面図である。実施の形態1の図2に対応する図であり、同等部分は同一符号で示している。真空遮断器の縦断面図は実施の形態1の図1と同等なので図示および説明は省略する。以下、実施の形態1との相違点を中心に説明する。
また、ブッシング2a、2bは、配列方向の軸線に対し直交方向に並べて配置され、上部が外側に開くように傾斜させて圧力タンク17に取り付けられている。
一方、可動側接続導体13bは、真空バルブ9とは反対方向の長軸方向に寄せて、真空バルブ9および側壁と必要な絶縁距離を保って配置されている。
なお、上記の長軸方向の両側に寄せて配置される真空バルブ9と可動側接続導体13bの配置位置は、長軸の軸線上を意味するものではなく概略の方向を示すものである。
図4は、実施の形態3による真空遮断器を示す縦断面図である。実施の形態1の図1に対応する図なので、図1と同等部分は同一符号で示して説明は省略し、以下、相違点を中心に説明する。なお、平面図は、実施の形態1の図2、又は実施の形態2の図3と同等である。
操作機構10を水平配置にすることにより、図1のような配置と比較して、圧力タンクの内部の下方の省スペース化が可能となる。
なお、遮断器室7までを圧力タンク1とし、操作機構室8をその外部に別室として設ける場合は、圧力タンク1の下面のスペースを縮小できる。
なお、圧力タンク1は、実施の形態2のような平面視略楕円形状の圧力タンク17であっても良い。
図5は、実施の形態4による真空遮断器の、圧力タンクの配列方向に直交方向から見た、側面断面図である。但し、ブッシングは省略し、また、全体も説明に必要な部分以外は省略して簡略表記している。実施の形態3の図4と同等部分は同一符号で示し、説明は省略する。
各真空バルブ9の下方に、各圧力タンク1の配列方向に向けて水平に伸びる連結軸20が設けられ、各真空バルブ9の可動導体9bは、絶縁ロッド11と操作ロッド12と変換レバー18を介して連結軸20に接続され、連結軸20の端部が操作機構10と連結されている。
操作機構10で連結軸20を駆動する駆動力が変換レバー18を介して各真空バルブ9の可動導体9bに伝達されて、可動導体9bが上下方向に駆動され、各真空バルブ9の両電極が接離するように構成したものである。
また、圧力タンク1は、実施の形態2のような平面視略楕円形状の圧力タンク17であっても良い。
更に、連結軸20は、図5のように、圧力タンク1内を区画した操作機構室8に設ける場合のほか、圧力タンク部を遮断器室7部分のみとし、その圧力タンクの外部の下部に設けてもよい。
また、圧力タンク内部の下方空間、又は、圧力タンク外部下方の空間を有効に利用して省スペース化が図られる。
