Definitions

  • the invention relates to a method of assembling structures of revolution and in particular of a support in laminate material and a fitting for the manufacture of a electrical insulator.
  • Patent EP-A- 0 125 421 describes such a process in which the fitting is fixed to the support surrounded by fins by means of an intermediate elastomer crown on which the fitting is pressed before the vulcanization of the intermediate crown.
  • An electrical insulator comprising a support laminate, cylindrical, frustoconical, bitronconic, in a "barrel” or other form of revolution, and a pair of fittings fixed respectively to the ends of the support, is used for example, as a support for equipment and conductors, as an enclosure of equipment and crossings.
  • the object of the invention is to propose a method to obtain an assembly between the support laminate and each fitting that has the required mechanical properties and sealing, in particular holding under a couple of bending reaching 30000Nm and under internal pressure of the 2MPa dielectric gas (20 bar) and a leak rate less than 1/100 of the interior volume per year.
  • Another object of the invention is to propose such a assembly process which is easy to implement and certain steps of which can be carried out in parallel with so as to reduce manufacturing time as much as possible of the insulator.
  • the subject of the invention is a method assembly of a laminate support with a fitting for the manufacture of an electrical insulator, in which the fitting has a ring which is fixed by shrinking and gluing on a complementary bearing located at one end of the support.
  • the support and the fitting are prepared so the diameter of the ring is slightly smaller than the diameter of the span.
  • the hardware is heated to dilate the diameter of the ring enough to that it becomes slightly larger than the diameter of the worn so that you can insert the ring on the seat and fix the fitting on the support by shrinking and gluing.
  • the main structure of the electrical insulator includes a laminated support 1 insulating material composite, here a hollow frustoconical tube, manufactured by example by winding mineral fibers or threads or organic, such as glass fibers, agglomerated by a curable synthetic resin comprising the epoxy resin.
  • the support can present other forms of revolution and / or be full to form a bar or a rush.
  • Two fittings respectively 2 and 3 in an alloy metallic (aluminum, cast iron, steel, etc ...), are fixed at the ends of the support on spans 12 and 13 by hooping and bonding.
  • Insulation 4 made of an elastomeric material like silicone, covers the outside surface of the support 1 and part of the exterior surface of the fittings as shown in the figure. This insulation is used to increase the creepage distance of the electrical insulator and strengthen the tightness of the envelope.
  • each fitting 2 and 3 on the support 1 we prepares, by machining, the ring of each fitting and each carried at the ends of the support so that the diameter of each ring is slightly smaller than the diameter of the litter which receives this ring.
  • the laminate support 1 is mounted on a lathe equipped with a means suitable centering, such as a telescope, which is used to position place and insertion, along the longitudinal axis of the support, of each fitting on each end of the support.
  • a means suitable centering such as a telescope
  • streaks of revolution are machined on the surface of each ring to create seals glue at the time of assembly so as to ensure the tightness of it.
  • a streak thickness of the order a few tenths of a millimeter is suitable for sealing.

  1. Verfahren zum Zusammenbau eines Trägers (1) aus Schichtmaterial mit einer Armatur (2, 3) zur Herstellung eines elektrischen Isolators, dadurch gekennzeichnet, daß die Armatur einen Ring (20) besitzt, der auf einer komplementären Auflagefläche (12, 13) an einem Ende des Trägers befestigt wird, wobei der Träger und die Armatur so vorbereitet werden, daß der Durchmesser des Rings geringfügig kleiner als der Durchmesser der Auflagefläche wird, und daß die Armatur erwärmt wird, um den Durchmesser des Rings so stark aufzuweiten, daß er etwas größer wird als der der Auflagefläche und der Ring auf diese Auflagefläche aufgesetzt werden kann, sodaß die Armatur auf dem Träger durch Schrumpfen und Kleben befestigt wird.
  2. Verfahren nach Anspruch 1, bei dem Riefen in Umfangsrichtung in die Oberfläche des Rings eingeschnitten werden, um Dichtungsringe aus Klebstoff zu bilden.
