Abstract:
Dispositif de contrôle d'une manœuvre d'au moins un organe mobile d'un sectionneur (2) pour l'ouverture ou la fermeture du sectionneur (2), cet organe étant mis en mouvement par un système de transmission entraîné par un moteur (5) électrique alimenté par un circuit d'alimentation (6) piloté par une unité de commande (7) en fonction d'un ordre de manœuvre. Le dispositif de contrôle comprend au moins : - la mesure d'une position angulaire (Θ) instantanée de l'organe par rapport à une position angulaire de référence correspondant à une ouverture ou à une fermeture du sectionneur (2); - la mesure de la puissance (P) électrique instantanée fournie au moteur (5) pour déplacer ledit organe mobile à ladite position angulaire (Θ) instantanée; - la comparaison de ladite puissance (P) instantanée mesurée par rapport à une puissance électrique de référence (Pref(0)) correspondante fonction de ladite position angulaire instantanée (Θ) mesurée; et - la génération d'un signal d'indication de défaut lorsque ladite puissance (P) instantanée mesurée diffère de ladite puissance de référence (Pref(0)) d'une valeur prédéterminée.
Abstract:
The invention relates to a device for piloting an electric motor (20) for driving a mobile conductor element (18) of a power switch connected to a power circuit (28) connected to two terminals (P, M) of an electrical battery pack, especially pertaining to a motor vehicle. The mobile element (18) can be displaced between opening and closing positions of the power switch. Said piloting device comprises static-type means (36) forming a power supply switch for the motor, said means comprising at least one transistor (T1, T'1) and being connected to a power supply circuit (40) for the motor (20), which, in turn, is connected to two terminals (P, M) of the battery. The inventive device also comprises static-type safety means (50) provided with a freewheeling diode (R1, R'1) connected to each transistor (T1, T'1), for the automatic displacement of the power mobile element (18) into the opening position when the polarities of the terminals (P, M) of the battery are inopportunely inverted.
Abstract:
An electrical contactor (10) comprising first and second electrical contact elements (16,18), a cam adapted for rotation by an electric motor (14), and a first actuator (34) engageable with the cam (38) such that rotation of the cam. moves the first actuator (34), which movement of the first actuator (34) causes the first contact element (18) to move into and out of engagement with the second contact element.
Abstract:
An actuator for a circuit breaker at or near a pole top, including an electric motor and gear box drive assembly which is operable to provide output drive from the gear box to a circuit breaker either by operation of the electric motor or manually, including an electric motor and a step-down gear box movably mounted relative to one another such that the motor drive is in one relative position between the motor and the gear box connected through the gear box to an output drive from the gear box, and is in another relative position between the motor and the gear box disconnected through the gear box, and a manual drive shaft to the gear box which can be manually rotated to provide output drive from the gear box at least when the motor is disconnected from the output shaft from the gear box, without back driving the electric motor.
