Electrical equipment for distribution network with fault detection, disconnection and elimination system

摘要

The present invention relates to electrical equipment for electricity distribution networks, e.g. a multiphase self-protected transformer, with the special feature that said electrical equipment comprises a fault detection system, a fault disconnection system and a fault elimination system, the fault detection system and the fault disconnection system being linked electromechanically. The fault detection system comprises at least one sensor that is sensitive to variations in at least one parameter of the dielectric liquid contained in the tank of the electrical equipment; the fault elimination system comprises at least one fuse and the fault disconnection system comprises a switch disconnector, so that in the case of an event indicating a fault, the fault elimination system and/or the fault disconnection system disconnects the electrical equipment.
