Title (EN) RAPID ONSET OVERLOAD PREDICTION AND PROTECTION
(FR) PRÉVISION ET PROTECTION CONTRE L'APPARITION DE SURCHARGE RAPIDE
Abstract:
(EN) A clutch controller provides protective disengagement of a clutch between an engine and driven machinery to prevent engine failure due to rapid onset overload. Sensor signals of measured parameters are used by the controller to determine potential engine failure. Multiple, successive sensor signals and elapsed times are assessed during which the current sensor signal value and the scaled rate of change in signal values is compared against a predefined amount. The clutch controller sends a clutch disengagement signal if a calculation result is indicative of imminent failure.
(FR) L'invention concerne un dispositif de commande d'embrayage qui permet d'effectuer un débrayage de protection entre un moteur et une machinerie entraînée afin d'éviter une défaillance du moteur due à une apparition de surcharge rapide. Des signaux de capteur de paramètres mesurés sont utilisés par le dispositif de commande pour déterminer une défaillance de moteur potentielle. Il est évalué de multiples signaux de capteur successifs et des laps de temps écoulés pendant lesquels la valeur de signal de capteur actuelle et le taux de changement échelonné dans les valeurs de signal sont comparés à une quantité prédéfinie. Le dispositif de commande d'embrayage envoie un signal de débrayage si un résultat de calcul indique une défaillance imminente.
