Abstract
Description
Claims (1)
- 第1と第2の2つの固定接触子とこれら両固定接触子に選択的に接触する可動接触子とを有するC接点式のスイッチ部を3個並設した三相切替接触器であって、
これら3個のスイッチ部の3個の可動接触子は、共通の軸線を支点にして、各スイッチ部の第1固定接触子に接触する第1接触位置と各スイッチ部の第2固定接触子に接触する第2接触位置とに揺動自在であり、
前記軸線と同じ軸線を支点にして揺動自在な、3個の可動接触子に対応する3個のレバー部材と、これらレバー部材を互いに同期して揺動するように連結する連結部材と、これらレバー部材を揺動させる単一の電磁アクチュエータと、各可動接触子と対応する各レバー部材との間に設けられるバネとを備え、
各バネは、前記軸線から径方向に離れた各可動接触子の所定箇所を第1作用点、前記軸線から径方向に離れた各レバー部材の所定箇所を第2作用点として、第1作用点と第2作用点とに対し両作用点を結ぶ直線方向に付勢力が作用し、且つ、前記軸線と第1作用点とを通る直線上に第2作用点が位置する死点位置で付勢力が最も強くなるように配置され、各レバー部材が死点位置を超えて一方と他方に揺動したとき、各可動接触子が夫々第1接触位置と第2接触位置に各バネの付勢力で揺動されるようにしたことを特徴とする三相切替接触器。
