Title (EN) VACUUM SWITCHING DEVICES
(FR) DISPOSITIFS DE COMMUTATION À VIDE
Abstract:
(EN) An alternating current vacuum switching device (100) for switching an electrical circuit under load and no load conditions, and optionally short-circuit conditions is disclosed. In particular,a the switching device (100) comprises:a vacuum evacuated housing(110);first (122) and second (120) electrodes within the housing; and an actuator (144) for moving the first electrode (122) relative to the second electrode (120) to mechanically engage and disengage the electrodes to perform a switching function, wherein the first electrode (122) is wholly located within the vacuum evacuated housing (110) such that movement of the switching function occurs solely within the housing(110). By having movement of the switching function solely within the housing, the reliability of the vacuum switching device is improved.
(FR) L'invention concerne un dispositif de commutation à vide pour courant alternatif (100) permettant de commuter un circuit électrique dans des conditions avec charge et sans charge, et facultativement des conditions de court-circuit. En particulier, le dispositif de commutation (100) comprend : un boîtier mis sous vide (110); des première (122) et deuxième (120) électrodes dans le boîtier; et un actionneur (144) permettant de déplacer la première électrode (122) par rapport à la deuxième électrode (120) afin d'accoupler et désaccoupler mécaniquement les électrodes pour effectuer une fonction de commutation, la première électrode (122) étant située entièrement dans le boîtier mis sous vide (110) de façon que le mouvement de la fonction de commutation se produise uniquement dans le boîtier (110). Avec le mouvement de la fonction de commutation uniquement dans le boîtier, la fiabilité du dispositif de commutation à vide est améliorée.
