Abstract
Description
なお、各図間において、同一符号は同一あるいは相当部分を示す。
図1は、この発明の実施の形態1による三位置開閉器操作機構を示す正面図、図2は、図1からシャッター板2を除いた状態の正面図、図3は、図1のA-A線の断面図である。
シャッター板2は、断路器(図示せず)又は接地開閉器(図示せず)の開閉操作を行わない場合、第1操作部(以下「断路器操作部」という)8及び第2操作部(以下「接地開閉器操作部」という)9を隠してカバーする(覆う)ように配設されている。
このとき、後述するプランジャー12a、12bによってシャッター板2の揺動は規制されている。
固定板13には、上記したモード切替プレート4a、4b、4cの揺動角度に応じて接点動作を行うリミットスイッチ10(第1リミットスイッチ10a、第2リミットスイッチ10b、第3リミットスイッチ10c)と、断路器用インターロックコイル11a、接地開閉器用インターロックコイル11b、及び、それらのコイル11a、11bの励磁でそれぞれ駆動されるプランジャー12a、12bなどが配設されている。
断路器を操作する場合は、図5(a)で示すように、レバー3を時計方向に角度8°~25°揺動させることで、モード切替プレート4aがリミットスイッチ10aの接点を閉じ、断路器用インターロックコイル11aを付勢する。するとプランジャー12aがコイル内に引き込まれ、シャッター板2はプランジャー12aとの干渉(規制)を解かれ、引き続き時計方向へ揺動させることができる。
シャッター板2の揺動角度が角度25°~30°で、モード切替プレート4aがリミットスイッチ10aの接点を開き、断路器用インターロックコイル11aが消勢され、プランジャー12aが戻る。
なお、シャッター板2の動作角度8°~25°の間でのみリミットスイッチ10aの接点を閉じるように構成することで、断路器用インターロックコイル11aが接地開閉器切状態であるというインターロック条件を満たす場合、コイルが常に付勢し発熱することのないようにされている。
接地開閉器用インターロックコイル11bの電気的インターロックは、図7で示すような回路を設けることで、対応するインターロック条件が断路器入状態の場合にロック作動とし、断路器切状態の場合にロック解除としている。
接地開閉器を操作する場合は、図6(a)で示すように、レバー3を反時計方向に角度8°~25°揺動させることで、モード切替プレート4bがリミットスイッチ10bの接点を閉じ、接地開閉器用インターロックコイル11bを付勢する。するとプランジャー12bがコイルに引き込まれ、シャッター板2はプランジャー12bとの干渉(規制)を解かれ、引き続き反時計方向へ揺動させることができる。
断路器用インターロックコイル11aの電気的インターロックは、図7で示すような回路を設けることで、対応するインターロック条件が接地開閉器入状態の場合にロック作動とし、接地開閉器切状態の場合にロック解除としている。
又、シャッター板2が一体で形成されていることにより部品同士の組み合わせによるガタを削減し、モード切替プレート4a、4b、4cによるリミットスイッチ10a、10b、10cの接点動作の信頼性が向上できる。
なお、シャッター板2を非磁性の金属で形成することにより、断路器用インターロックコイル11aや接地開閉器用インターロックコイル11bの磁束の影響を受け難いようにしている。
図4は、実施の形態2におけるシャッターの組立状態を分解した斜視図である。
図4において、復帰ばね15は、揺動軸7でばね受け5上に保持され、固定ねじ16でシャッター板2が揺動軸7に固定されている。
シャッター板2を時計方向及び反時計方向に揺動操作させた時、復帰ばね15は、復帰ばね支持部17a及び17bで受け止められるとともに圧縮されるので、断路器又は接地開閉器の開閉を操作した後、復帰ばね15によりシャッター板2は初期状態に戻すことができる。
