    • 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.

    • 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.
    • 包括至少一个电介质(2)和轴向固定在电介质上的铁或钢盖(3)的电绝缘体(1)具有用于保护盖免受腐蚀以及电弧的装置。 在一个实施例(图1-3)中,保护装置包括形成为具有用于雨水出口的中心孔(11)和出口孔(12)的盘的锌或铝部分(10)。 部分(10)的外壁(13)向上朝着盖(3)向上弯曲,并且部分(10)的一部分设置在盖(3)的基部(6)和外表面(7)之间, 的电介质(2)。 在另一个实施例(图4)中,保护装置包括由锌或铝形成并且直接围绕盖(3)的基部(6)铸造的半环形的实体旋转体(30),并且 具有在盖(3)的基部(6)和电介质(2)的外表面(7)之间延伸的薄凸缘。 固体旋转体(30)的外表面(31)向上弯曲,以便在这种外表面和电介质(2)的外表面(7)之间提供用于自熄电弧的区域。
