Title (EN) METHOD FOR OPERATING A MEDIUM VOLTAGE CIRCUIT BREAKER OR RECLOSER AND MEDIUM VOLTAGE CIRCUIT BREAKER OR RECLOSER ITSELF
(FR) PROCÉDÉ PERMETTANT DE FAIRE FONCTIONNER UN DISJONCTEUR MOYENNE TENSION OU UN DISJONCTEUR À RÉENCLENCHEMENT ET DISJONCTEUR MOYENNE TENSION LUI-MÊME OU DISJONCTEUR À RÉENCLENCHEMENT LUI-MÊME
Abstract:
(EN) The invention relates to a medium voltage circuit breaker or recloser equipped with an electromagnetic drive and with means for monitoring the travel curves of the closing and opening operation, according to the preamble of claim 1. In order to avoid the need of positioning sensors at the drive chain of the circuit breaker or recloser, and to determine its travel curve with high accurancy, the invention is, that the travel curve is derived by the evaluation of the shape of the applied current and the shape of the applied voltage, using a mathematical representation of the electromagnetic actuator.
(FR) L'invention se rapporte à un disjoncteur moyenne tension ou à un disjoncteur de réenclenchement équipé d'un entraînement électromagnétique et de moyens permettant de surveiller les courbes de déplacement de l'opération de fermeture et d'ouverture, selon le préambule de la revendication 1. Afin d'éviter le besoin de capteurs de positionnement au niveau de la chaîne d'entraînement du disjoncteur ou du disjoncteur à réenclenchement et de déterminer sa courbe de déplacement avec une précision élevée, l'invention consiste en ce que la courbe de déplacement est dérivée par l'évaluation de la forme du courant appliqué et de la forme de la tension appliquée, à l'aide d'une représentation mathématique de l'actionneur électromagnétique.
