摘要:
The invention relates to a storage control system (100) for one or more electrical breaking poles (10), comprising: a storage mechanism (200) comprising a control handle (102) movable at least between a closed position and a breaking position, and vice versa, a first link rod (600) connected to an outer carriage (220) and pivoting about a first point of rotation between a first position and a second position, and vice versa, by actuation of the control handle (102) of the storage mechanism (200) between the breaking position and the closed position, and vice versa, a second link rod (700) pivoting about an axis of rotation (722) and connected to the first link rod (600) by a sliding connection (710, 613) such that the movement of the first link rod (600) between the second position and the first position pivots the second link rod (700) about the axis of rotation (722) between a closed position of one or more breaking poles and an open position of same. The control system further comprises means for exerting an additional pivoting force on the second link rod (700) when the control handle is actuated beyond the breaking position.

Le disjoncteur (1) comprend deux polarités (PN, PP) incluant chacune deux pôles (3, 5) connectés en parallèle, chaque pôle (3, 5) comportant un interrupteur (9) et un déclencheur (7). Chacune des polarités (PN, PP) comporte un égaliseur (13) formé par un conducteur connectant électriquement la liaison entre l'interrupteur (9) et le déclencheur (7) d'un premier pôle (3) et la liaison entre l'interrupteur (9) et le déclencheur (7) du second pôle (5).
摘要:
Die Vorrichtung (V) dient dem Melden der Schalterstellung eines Niederspannungsschalters (S). Sie weist einen in Funktion der Schalterstellung mechanisch positionierbaren Auslöser (30) auf und einen vom Auslöser (30) gesteuerten Hilfsschalter, bei dessen Öffnen oder Schliessen sich in einem den Hilfsschalter enthaltenden Signalstromkreis ein die Schalterstellung meldendes elektrisches Signal bildet. Der Auslöser (30) enthält einen mit einem beweglichen Schaltstück (22) des Niederspannungsschalters verbundenen Magnetfeldgeber (36), welcher mit einem den Hilfsschalter bildenden Sensormodul (40) zusammenwirkt. Um eine hohe Betriebssicherheit der Meldevorrichtung (V) zu erreichen und um deren nachträglichen Einbau in den Schalter (S) zu erleichtern, ist das Sensormodul (40) auf einer von der Einbauseite abgewandten Bedienungsseite (11) des Schalters (S) befestigt, weist der Auslöser (30) einen plattenförmigen Gleitkörper (32) einer Gleitführung auf, ist der Magnetfeldgeber (36) entweder auf dem Gleitkörper (32) angeordnet oder bildet der Magnetfeldgeber den Gleitkörper, und ist der Gleitkörper (32) entlang einer im Bereich der Bedienungsseite (11) in die Innenflächen der beiden Gehäusehälften eingeformten Führungsbahn (33) verschiebbar gelagert.
摘要:
The invention relates to a remote control unit (20) for an electric protection system (1), wherein the opening and/closing of the contacts are controlled via a joystick (50) driven via a mechanism (150) by a unidirectional electromagnetic actuator (120). The driving mechanism (150) includes a system with two hinged arms: a lever (151) attached to the core of the electromagnet, and a connecting rod (160) having one end (161) interacting with the joystick (50). In order to avoid the stresses due to the double abutment of the joystick (50) and the electromagnet (120), the connecting rod (160) is telescopically shaped with spring means (162) capable of building up energy upon actuation and enabling the coupling end (161) to couple with the joystick (50) to assume two positions for each position of the means (153) for attaching the driving mechanism (150) to the electromagnet (120).
