Abstract

An inductive electrical apparatus including a box in which a set of magnetic core and windings are arranged and at least one through insulating terminal for the introduction of an electrical conductor, at least one fuse set arranged under a preset level of dielectric liquid, said fuse assembly comprising an elongated fuse tube, of insulating material and hermetically closed at both ends, a terminal element at each end of the tube, a solid lining made of a material arranged to release an arc extinguishing material housed in the interior of the tube and defining in it an arcing passage, a fuse element disposed in the passage and electrically connected to the terminal elements, and means of electrically interconnecting the fuse assembly between the electrical conductor of the passage isolating terminal and a winding of the core assembly and windings.
