Abstract
Description
以下、本発明の実施の形態1を示すにあたり回路遮断器の開閉機構を図に基づいて説明する。図1はこの発明の実施の形態1による回路遮断器のカバーを外した外観斜視図、図2は図1におけるOFF状態を表す断面図、図3~4は回路遮断器の開閉機構を示す要部側面図であり、図3は閉路(オン)状態、図4は開路(オフ)状態、図5はトリップ状態、図6はリセット状態を示す。
リセット動作が完了した状態は、図7に拡大して例示してある。トリップバー33にトリップバースプリング35の付勢力が作用する作用点が、トリップバースプリング35の先端部と、トリップバースプリング35の先端部と前記トリップバースプリング35の支承点(トリップバースプリング35の回転中心である支点34a)との間に形成されている。
この状態から遮断器はトリップ動作を行う過程で引外し完了位置(図8(b)参照)までは前記同様に第一係合部33aで当接していることでこの間のトリップバー33のトリップバースプリング35による回転モーメントはほぼ一定であるため、引外し装置による引外し完了まではトリップバー33の引外し時の荷重を急激に増大させることはない。その後、引外し完了後、トリップ位置(図8(c)参照)までの範囲になるとトリップバー33とトリップバースプリング35は第一係合部33aと別に設けられた突起33bで当接する。そのため、トリップバー33とトリップバースプリング35はトリップバースプリング35の根本側で当接することになりトリップバースプリング35による回転モーメントが急激に増大する。すなわち、トリップバー33が前記トリップ動作(紙面上の時計方向の回転)と逆の動き(紙面上の反時計方向の回転)を行うリセット動作においては、リセット時にトリップバー33の復帰力が増大することになり、主に短絡遮断時に発生する溶融物、煤等の影響に起因するリセット不能を防止することが可能になる。つまり、遮断時の煤がトリップバー33の回転軸37部に付着しこの付着により回転軸37部でのトリップバー33の回転に対する摩擦が増大して、トリップバー33の回転を妨げてしまうことにより、トリップバースプリング35のスプリング力が小さいとリセット不能になる場合が生じるが、本実施の形態1によれば、前述のように、リセット不能を防止することが可能になる。
なお、トリップバー33にトリップバースプリング35によって作用する回転モーメントの中心(ラッチ34の支点34a)は変わらず、トリップバー33とトリップバースプリング35の当接位置(作用点)が変わる(図示33aが33b(実施の形態1の場合)もしくは33c(後述の実施の形態2,3の場合)に変わる)ことにより、トリップバー33の回転モーメントが増大する。
以下、本発明の実施の形態2を図9の実施例に基づいて説明する。2段階で回転モーメントを得るために、トリップバースプリング35のトリップバー33側の一端を屈曲部35aから曲げた形状とする。これにより、実施の形態1と同様な効果が得られ、引外し装置による引外し完了まではトリップバー33はトリップバースプリング35とトリップバー33の第一係合部33aで当接しているので引外し時の荷重を増大させることなく、また引外し完了後は当接位置がトリップバー33の第二係合部33cに変わることでリセット時のトリップバー33の復帰力を増大させることができ、主に短絡遮断時に発生する溶融物、煤等の影響に起因するリセット不能を防止することが可能になる。
以下、本発明の実施の形態3を図10の実施例に基づいて説明する。
実施の形態1で示したトリップバー33の突起33bと、実施の形態2で示したトリップバー33側の一端を屈曲部35aから曲げた形状としたトリップバースプリング35とを併用したものである。これにより、更に大きな効果を得ることが可能となる。
