Abstract
(EN) This switch (20) comprises: a fixed contact (32); a movable contact (31); motors (22, 49) that drive the movable contact (31) via a drive mechanism (30) that converts a rotary motion into a linear motion; and drive control devices (21, 47) that drive and control the motors (22, 49). The drive control devices (21, 47) control the rotation speed of the motors (22, 49) during the open operation of the switch (20) such that the moving speed of the movable contact (31) in a part of the entire movement range of the movable contact (31) is lower than the moving speed of the movable contact (31) when the switch (20) is turned on. The part of the entire movement range includes a breaking point where the arc current is extinguished.
(FR) La présente invention concerne un commutateur (20) qui comprend : un contact fixe (32); un contact mobile (31); des moteurs (22, 49) qui entraînent le contact mobile (31) par le biais d'un mécanisme d'entraînement (30) qui convertit un mouvement rotatif en un mouvement linéaire; et des dispositifs de commande d'entraînement (21, 47) qui entraînent et commandent les moteurs (22, 49). Les dispositifs de commande d'entraînement (21, 47) commandent la vitesse de rotation des moteurs (22, 49) durant le fonctionnement ouvert du commutateur (20) de sorte que la vitesse de mouvement du contact mobile (31) dans une partie de la portée complète de mouvement du contact mobile (31) est inférieure à la vitesse de mouvement du contact mobile (31) lorsque le commutateur (20) est actionné. La partie de la portée complète de mouvement inclut un point de rupture où le courant d'arc est éteint.
(JA) 開閉器(20)は、固定コンタクト(32)と、可動コンタクト(31)と、回転運動を直線運動に変換する駆動機構(30)を介して、可動コンタクト(31)を駆動するモータ(22,49)と、モータ(22,49)を駆動制御する駆動制御装置(21,47)とを備える。駆動制御装置(21,47)は、開閉器(20)の開放動作時において、可動コンタクト(31)の全移動範囲の一部における可動コンタクト(31)の移動速度が、開閉器(20)の投入動作時における可動コンタクト(31)の移動速度よりも低速度になるように、モータ(22,49)の回転速度を制御する。上記の全移動範囲の一部は、アーク電流が消弧する遮断点を含む。
