Definitions

  • the present invention relates to an insulator comprising a dielectric element in tempered glass having the shape of a plate and having a cylindrical head, at least one rod of which at least one end is sealed in the housing defined by the head of a dielectric element, said rod having in the vicinity of its sealed end a collar with an outside diameter greater than the outside diameter of the head in which said end is sealed, and at least one cover covering the head with a dielectric and sealed on the latter.
  • Such an insulator is known, for example from document FR-A-1 166 372.
  • such insulators are constituted by a multiplicity of such elements making up a chain with multiple dielectrics.
  • the first cover comprises a member for fixing to a support
  • the last rod is extended by a member for supporting an electric cable.
  • a cover and a rod are produced in a single piece which comprises a first part which is a rod for a dielectric and a second part which is a cover for the following dielectric.
  • the dielectrics are often made of tempered glass, and in the event of destruction of a dielectric, for example by peeling, as happens when a rifle bullet is fired on an insulator dielectric, there does not remain then more than glass debris forming the bottom of the dielectric head and the cylindrical area between the cover and the rod.
  • the present invention aims to overcome these drawbacks, and relates to an insulator such as that described above, characterized in that the cover has a flared base covering an annular portion of the dielectric extending beyond the diameter outside of the head, so as to define a rigid extension on either side of the dielectric element, and that the annular portion of the dielectric between the flange of the rod and the flared base of the cover is present on the side of the cover a circular boss covered by the flared base of the cover, and on the side of the collar a circular reinforcement to which the collar extends.
  • the assembly shows a partial view of an insulator in which there are two dielectrics 1 and 2.
  • the dielectric 1 conventionally consists of a substantially plate-shaped part 3 having a cylindrical head 4 ; this dielectric 1 is usually made of tempered glass.
  • a metal rod 5 is sealed by one end in the housing defined by the head 4 of the dielectric 1, by means of a mass of cement mortar 6.
  • a metal cover 7 is also sealed on the head 4 of the dielectric 1 by mortar of cement 8.
  • a metal rod 9 is sealed inside the head 10 of the dielectric 2 by mortar 11, and a metal cover 12 is sealed on the head 10 of the dielectric 2 by mortar 13.
  • the assembly is carried out in a chain by means of a rod-cover 14 here, the rod 5 of the rod-cover 14 serving for the attachment of the dielectric 1 while the cover 12 of the rod-cover 14 is used to attach the dielectric 2.
  • the rod 5 has, just below the plate-shaped part 3 of the dielectric 1, a flange 15 whose diameter extends beyond the diameter of the head 4 of the dielectric 1, and the cover 7 has a flared base 16 which covers a portion of the upturned portion 3 of the dielectric 1, so that a zone 17 substantially horizontal of the dielectric 1 is thus trapped between the flange 15 and the flared base 16 of the cover 7.
  • the fragments of the area 17 remain trapped and participate in the resistance to bending of the assembly.
  • the plate-shaped part 3 has a circular reinforcement 18 and a boss 19 giving it a profile in the form of a stair step.
  • the base 16 of the cover 7 extends to cover the boss 19; likewise, the flange 15 extends to the reinforcement 18.
  • the rod-cover 14 advantageously comprises reinforcement ribs 40 connecting the flange 15 to the cover 12.
  • the dielectrics 20, 21, 22 are arranged head to tail.
  • the assembly is then carried out by means of double rods 23, 24 and double hoods 25, 26.
  • the rods also have flanges 27, 28, 29, and the hoods of the flared bases 30, 31, 32.
  • rods and hoods are sealed but it is also possible to adopt the solution with double rods and double hoods poured by gravity on a crimped sleeve according to the technique described for example in FR-A-2 209 937.
