摘要： An electrical insulator (1) of the type comprising at least one dielectric (2) and an iron or steel cap (3) fixed axially on the dielectric has a device for protecting the cap against corrosion as well as electric arcs. In one embodiment (FIGS. 1-3), the protection device comprises a zinc or aluminum part (10) shaped as a dish with a center hole (11) and outlet holes (12) for the egress of rainwater. The outside wall (13) of the part (10) curves upwardly toward the cap (3) and a portion of the part (10) is disposed between the base (6) of the cap (3) and the outer surface (7) of the dielectric (2). In another embodiment (FIG. 4), the protection device comprises a solid body of revolution (30) of semi-toroidal shape which is formed of zinc or aluminum and is cast directly around the base (6) of the cap (3) and has a thin flange extending between the base (6 )of the cap (3) and the outer surface (7) of the dielectric (2). The exterior surface (31) of the solid body of revolution (30) curves upwardly so as to provide between such exterior surface and the outer surface (7) of the dielectric (2) an area for the self-extinguishing of electric arcs.

摘要： A device for detecting and indicating a fault current flowing through a lightning arrestor or an insulator, the current being DC or at AC mains frequency, the device being housed inside a box that is provided with a frangible window and that has a piece of metal electrically connected to an end fitting of the lightning arrestor or of the insulator passing therethrough. The device has: a transformer for transforming the current, the primary of the transformer being constituted by the piece of metal, and the secondary of the transformer being connected to a peak-limiting circuit to make pulses of current due to surges corresponding, in particular, to lightning strikes inoperative; a heating resistance fed by said transformer and constituting an igniter for a pyrotechnic composition in which it is embedded, the composition being designed to break the frangible window; and preferably indicator means suitable for being released by rupture of the frangible window.

摘要： The lightning arrestor has two metal end fittings for connection purposes, a stack of electrically conductive components extending along a longitudinal axis between the two end fittings, and an envelope surrounding the electrical components and the end fittings in such a manner as to maintain electrical contact between the components. The envelope is made of a thermoplastic material that molded over the electrical components and the end fittings. It has an embossed outside surface including depressions and projections. The depressions correspond to zones of reduced envelope wall thickness and they serve to constitute lateral openings through the envelope for allowing gas to escape to the atmosphere.
