しかしながら、上述のような従来の操作器では、カム及び主レバーを有する伝達機構が、軸を支持する複数個の軸受装置間に配置されているので、構成部品数が多くかつ構成が複雑になり、大型化する。また、軸受装置間に配置された伝達機構に外部からアクセスし難く、操作器の保守,点検の作業性が悪いと共に、操作器の保守,点検作業に多大な作業時間が必要となる。
【0004】
本発明の目的は、操作器の保守,点検の作業性が向上すると共に、操作器の構成を簡素化して小型化を図った開閉器用操作器を提供することにある。
【0005】
【課題を解決するための手段】

【0006】
また、本発明の開閉器用操作器は、上記目的を達成するために、カム軸及び主軸と、前記カム軸の一方側に設けられたカムと、電動機の駆動力を前記カム軸に伝達すると共に、前記カム軸の他方側に設けられ、かつ投入ばねの駆動力が伝達される主ギアと、前記カムの荷重が伝達されると共に、前記主軸の一方側に設けられ、かつ前記投入ばねの駆動力を遮断ばねに伝達する主レバーと、前記投入ばねの駆動力を緩衝装置に伝達すると共に、前記主軸の他方側に設けられた緩衝レバー或いは前記投入ばねの駆動力を開閉器の接点に伝達すると共に、前記主軸の他方側に設けられた接点レバーとを備え、前記カム軸は、前記カムと前記主ギア間で一つの軸受装置によってブラケットに支持され、前記主軸は、前記主レバーと前記緩衝レバー或いは前記接点レバー間で一つの軸受装置によってブラケットに支持されていることを特徴とする
【0007】
【発明の実施の形態】
以下、本発明の実施例を図1〜図6に基づいて説明する。
【0008】
図6は、本実施例の操作器を適用した遮断器の外観構成を示す。遮断器100は、変電所や開閉所などの電気所に設置される開閉装置であり、絶縁性ガス、例えばSF6(六弗化硫黄)ガスが封入された円筒形のタンク110に可動接触子及び固定接触子からなる電気的な接点(図示省略)を収納している。電気的な接点は、タンク110の左下側の操作箱120に収納された操作器とリンク機構を介して機械的に接続され、操作される。
【0009】
タンク110は金属製の密閉容器であり、横置き、すなわちその中心軸が地面に対して平行となるように設置された接地容器である。タンク110の周壁の上部にはブッシング130,140が設けられている。電力は上流側の系統からブッシング130を介して引込まれ、電気的な接点を介してブッシング140に送られ、ブッシング140を介して下流側の系統に引出される。系統に事故などが起きた場合は電気的な接点が開離し、上流側の系統から下流側の系統への電力供給を遮断する。
【0010】
図1〜図3は、操作箱120に収納された操作器の構成を示す。尚、図1及び図2では、図3に示されている接点レバーが省略されている。1はブラケットであり、軸受装置2,3を支持する支持体である。軸受装置2,3は、ブラケット1の直立部1aに対して直交するように直立部1aから左右両方向に突出した突出部1b,1cに設けられている。突出部1b,1cは筒状に形成されており、突出部1bの円筒内面の両端部には軸受装置2の軸受2a,2bが設けられ、突出部1cの円筒内面の両端部には軸受装置3の軸受3a,3bが設けられている。
【0011】
4はカム軸であり、軸受装置2によって回転自在に支持されている。5は主軸であり、軸受装置3によって回転自在に支持している。カム軸4の一方側(軸受2a側)にはカム6が設けられ、その他方側(軸受2b側)には主ギア7が設けられている。また、カム軸4の一方側、かつカム6の軸受2a側とは反対側には投入レバー8が設けられている。主ギア7にはギア9,10を介して電動機11の駆動力が伝達される。主ギア7及び投入レバー8にはピンを介して投入ばねリンク12が連結されている。投入ばねリンク12には投入ばね13が設けられている。カム軸4は、投入ばねリンク12を介して主ギア7及び投入レバー8に伝達された投入ばね13の駆動力によって回転し、カム6を回転させる。カム6は投入ばね13の駆動力を主軸5側に伝達する。
【0012】
主軸5の一方側(軸受3a側)には主レバー14が設けられ、その他方側(軸受3b側)には緩衝レバー15が設けられている。また、主軸5の他方側、かつ緩衝レバー15の軸受3b側とは反対側には接点レバー16が設けられている。主レバー14には、カム6の外周面と接触し、カム6の荷重が伝達されるローラー17がピンによって連結されている。また、主レバー14にはピンによって遮断ばねリンク18が連結されている。遮断ばねリンク18には遮断ばね19が設けられている。緩衝レバー15にはピンによって緩衝リンク20が連結されている。緩衝リンク20には緩衝装置21のダンパー22が連結されている。接点レバー16には、遮断器100の電気的な接点23に連結されたリンク機構の構成部品である接点リンク24がピンによって連結されている。
【0013】
また、操作器には、遮断器100の電気的な接点23の投入指令に基づいて投入ばね13の蓄勢状態を解除する閉路操作機構25と、遮断器100の電気的な接点23の開放指令に基づいて遮断ばね19の蓄勢状態を解除する開路操作機構26を備えている。閉路操作機構25は、プランジャーと呼ばれる構成部品を備えた閉路用ソレノイド27,閉路用フック28,閉路用レバー29によって構成されている。開路操作機構26は、プランジャーと呼ばれる構成部品を備えた開路用ソレノイド30,開路用フック31,開路用レバー32,33によって構成されている。
【0014】
次に、本実施例の操作器の動作を図4及び図5に基づいて説明する。図4は投入動作を示す。ここで、投入ばね13は蓄勢状態、遮断ばね19は放勢状態、遮断器100の電気的な接点23は開路位置にある。遮断器100の電気的な接点23の投入指令に基づいて閉路用ソレノイド27が励磁されると、閉路用ソレノイド27内部のプランジャーが矢印Aの方向に動作して閉路用フック28が押される。閉路用フック28は、黒点で示した部分を回転軸として矢印Bの方向に動作し、閉路用レバー29との係合を解除する。閉路用レバー29は、黒点で示した部分を回転軸として矢印Cの方向に動作し、カム6との結合を解除する。これにより、投入ばね13が開放され、投入ばねリンク12が矢印Eの方向に動作すると共に、カム6がカム軸4を回転軸として矢印Dの方向に動作する。これにより、カム6の外周面に接触するローラー17によって主軸5を回転軸とする主レバー14が矢印Fの方向に動作する。主レバー14の動作により主軸5が回転すると、接点レバー24が動作し、リンク機構を介して連結された遮断器100の電気的な接点23が投入される。これと同時に、遮断ばねリンク18が矢印Gの方向に動作され、遮断ばね19が蓄勢される。これにより、投入ばね13は放勢状態、遮断ばね19は蓄勢状態、遮断器100の電気的な接点23は閉路位置となる。
【0015】
この後、電動機11が動作し、電動機11の駆動力がギア9,10を介して主ギア7に伝達される。これにより、主ギア7と共にカム軸4、このカム軸4に設けられた投入レバー8が回転し、この回転によって投入ばねリンク12が矢印Hの方向に動作し、投入ばね13が圧縮される。この後、電動機11の電源が切られ、投入ばね13は蓄勢状態を維持する。
【0016】
図5は開離動作を示す。ここで、投入ばね13は放勢状態、遮断ばね19は蓄勢状態、遮断器100の電気的な接点23は閉路位置にある。遮断器100の電気的な接点23の開放指令に基づいて開路用ソレノイド30が励磁されると、開路用ソレノイド30のプランジャー矢印Aの方向に動作して開路用フック31が押される。閉路用フック31は、黒点で示した部分を回転軸として矢印Bの方向に動作し、開路用レバー32との係合を解除する。閉路用レバー32は、黒点で示した部分を回転軸として矢印Cの方向に動作し、閉路用レバー33との結合を解除する。閉路用レバー33は、黒点で示した部分を回転軸として矢印Dの方向に動作し、主レバー14との結合を解除する。これにより、遮断ばね19が開放され、遮断ばねリンク18が矢印Eの方向に動作すると共に、主レバー14が主軸5を回転軸として矢印Fの方向に動作する。これにより、主軸5が回転して接点レバー24が動作し、リンク機構を介して連結された遮断器100の電気的な接点23が開放される。
【0017】
以上説明した本実施例によれば、一つの軸受装置2によってカム軸4が片持ち支持されているので、複数個の軸受装置によって軸が支持されていた従来の操作器よりも構成部品が減り、構成が簡素化される。例えば、軸受装置を支持するブラケットが軸受装置の個数に合わせて一つとなるので、構成部品数が減り、構成が簡略化される。従って、構成部品数が減り、構成が簡略化された分、操作器を小型化することができる。例えば、構成部品が減ることにより、軸長を短くすることができるので、操作器を小型化することができる。また、一つの軸受装置3によって主軸5が片持ち支持されているので、さらに操作器を小型化することができる。さらにまた、ブラケット1の直立部1aに対して直交するように直立部1aから突出する突出部1b,1cに軸受装置2,3が設けられているので、さらに操作器を小型化することができる。
【0018】
また、本実施例によれば、軸受装置2,3の外側にカム軸4及び主軸5と一体となって回転するカム6,主ギア7,主レバー14,緩衝レバー15,接点レバー16などの回転体が配置されるので、操作器の構成部品に外部から容易にアクセスすることができる。従って、操作器の保守,点検作業が行い易くなり、操作器の保守,点検の作業性を向上させることができると共に、操作器の保守,点検の作業時間を短縮することができる。
【0019】
また、本実施例によれば、一つの軸受装置2によって支持されたカム軸4の一方側にカム6を配置すると共に、他方側に主ギア7を配置し、一つの軸受装置3によって支持された主軸5の一方側に主レバー14を配置すると共に、他方側に緩衝レバー15,接点レバー16を配置し、カム軸4及び主軸5のバランスをとっているので、一つの軸受装置によって片持ち支持された軸が傾いて変形したり、一方の軸に設けられた回転体と他方の軸に設けられた回転体との接触面の一端側にギャップが生じて片当たりとなって接触面の応力が過大となる恐れなどはない。
【0020】
【発明の効果】
以上本発明によれば、操作器の構成部品が減り、操作器の構成が簡素化されるので、操作器を小型化することができ、また、操作器を構成する各部品が軸受装置の外側に配置されるので、操作器の保守,点検の作業性を向上させることができる。
