Description

【0001】
【発明の属する技術分野】
本発明は主回路接点開閉用の密閉形開閉装置に関する。
【0002】
【従来の技術】
従来の密閉形開閉装置は、図2に示すように構成されている。すなわち、第1密閉容器31と第2密閉容器32は、スペーサ33を介して接続されており、スペーサ33を貫通して主回路導体34が配置されている。主回路導体34は可動側の主回路接点35に接続するように構成されている。主回路接点35の開閉操作は、第2密閉容器32の外部に設置されているモータ操作機構36により、絶縁操作ロッド37を駆動することで実行される。
【0003】
【発明が解決しようとする課題】
上述した従来の密閉形開閉装置では、主回路接点用開閉操作機構を密閉容器の外部に配置しているため、極度の縮小化の妨げになっていた。また、環境条件の劣悪な地域では、機器保護のために収納建屋の建設を必要とする場合が一般的であった。
【0004】
本発明は、このような従来の課題を解決するためになされたもので、機器の縮小化、配置設計の自由度の向上、耐候性能の向上した密閉形開閉装置を提供することを目的とする。
【0005】
【課題を解決するための手段】
本発明に係わる開閉装置は、内部に絶縁媒体が充填された密閉容器内に配置され一端に主回路接点が形成された一対の主回路導体と、一方の主回路導体の一部に装着されこの主回路導体に設けられた主回路接点を前進、後退させるモータ操作機構とから構成されている。
【0006】
更に本発明に係わる開閉装置は、前記一方の主回路装置に発電装置並びに蓄電装置が設けられている。
【0007】
更に本発明に係わる開閉装置は、前記発電装置が風力発電装置である。
【0008】
【発明の実施の形態】
以下に、本発明の実施形態の主要部を図1を参照して説明する。密閉形開閉装置を構成する第1密閉容器11並びに第2密閉容器12は気密に接続されており、内部にはSF6などの絶縁媒体14が充填されている。更に、第1並びに第2密閉容器11、12内部にはスペーサ13が設けられており、中央には第1並びに第2主回路導体15、16が設置されている。第1主回路導体15はスペーサ13を貫通して支持されている。
【0009】
本発明の実施形態においては、第1主回路導体15が可動側を形成しており、第2主回路導体16が固定側を形成している。第1主回路導体15の一部としてスペーサ13に支持されたモータ操作機構17が設けられている。これは、第1主回路導体15内部に同軸的にモータ電機子18が設置されており、モータシャフト19がこのモータ電機子18を支えている。モータ電機子18の第2主回路導体16側端部には主回路可動側接点20が結合しており、第2主回路導体16の先端には主回路固定側接点21が結合されている。第1並びに第2主回路導体15、16の各々の端部にはシールド22、23が設けられている。
【0010】
スペーサ13内には光ガイド26が貫挿されており、この光ガイド26は密閉容器外に設けられた光信号処理装置27に接続されている。モータシャフト19には螺旋状ネジ切りが施されており、モータの回転によりモータ電機子18並びにこれに付属した主回路可動側接点20が前進/後退し、結果として主回路可動側接点20と主回路固定側接点21間で開・閉動作が行われる。
【0011】
以上のような動作を実行するモータ操作機構17への操作指令授受は、光信号処理装置27から光ガイド26を介して行われる。一方、モータ操作電源としては、第1主回路導体15内に差圧風力電源ユニット24が設置されており、この電源ユニット24によって発電された電力は、モータシャフト19の周囲に設けられたモータ支持/制御機構兼蓄電ユニット25に蓄電される。モータの回転はこの蓄電ユニット25によって行われる。
【0012】
差圧風力電源ユニット24を作動させるためには、第1密閉容器11と第2密閉容器12間にガス圧差を設け、両容器間を移動するガス流をモータ操作機構17の周辺にあけられた通気孔28から中心部に設けた差圧風力電源ユニット24へ点線矢印にて示したように吹きつけることによって、風力発電を可能とした。第1密閉容器11、第2密閉容器12間のガス圧は別途設置したコンプレッサにより常に一定以上の差圧を付けておく。
【0013】
【発明の効果】
上述したような本発明に係わる開閉装置ではモータ操作機構の削減により、環境条件の劣悪な地域、例えば、極寒地域、酷暑地域、砂漠、水中等々における耐候性能を向上することができるようになった。また、開閉装置の配置設計の自由度が増加した。
