Abstract
L’invention porte sur un dispositif de protection et de monitorage pour transformateur du type à diélectrique liquide enfermé dans une cuve hermétique, le dispositif comprenant au moins un contacteur électromécanique de sécurité dont le basculement est destiné à provoquer l’ouverture instantanée d’un disjoncteur du transformateur. Le dispositif comprend un circuit de détection du basculement du contacteur électromécanique et une unité électronique de mesure reliée au circuit de détection et configurée pour tracer la survenance d’un événement de basculement. L’invention porte également sur l’utilisation d’un tel dispositif. Figure à publier avec l’abrégé : Fig. 2aThe invention relates to a protection and monitoring device for a transformer of the liquid dielectric type enclosed in a hermetic tank, the device comprising at least one electromechanical safety contactor whose switching is intended to cause the instantaneous opening of a circuit breaker of the transformer. The device comprises a circuit for detecting the tipping of the electromechanical contactor and an electronic measurement unit connected to the detection circuit and configured to trace the occurrence of a tipping event. The invention also relates to the use of such a device. Figure to be published with abstract: Fig. 2a
