Definitions

  • the present invention has for its object a new arrangement for the assembly comprising a conductive bar surrounded by a continuous sheath, whereby the bar and sheath respectively are capable of expanding freely from fixed points of construction, this arrangement'resulting furthermore in easy mounting of the assembly.
  • the arrangement in accordance with the invention is characterised by the fact that the insulators carrying the bar are positioned in openings formed in the sheath and are held'therein by way of a flange which is greater in diameter than the sheath opening and is exterior to the sheath, whilst the remaining part of the insulator is so dimensioned as to be able to pass through the sheath opening.
  • FIG. 1 is a diagrammatic illustration of the problem solved by the present invention.
  • FIGS. 2, 3 and 4 show the bar insulators in various dispositions.
  • FIG. 1 Shown on FIG. 1 is a sheath portion 1 surrounding a bar piece 2; the bar is supported by sets of insulators 3 and 4 whilst the sheath is held by supporting assemblies 5 and 6. Also shown on the drawing is a fixed point F of the sheath to be later described and a fixed point F of the bar which is obtained by blocking the insulator set 3 by way of stop members T secured to the bar. These fixed points F and F may be adjacent or remote from each other.
  • the insulator set 4 and the supporting assembly 6 enable the bar and sheath to expand freely as will be presently explained.
  • FIG. 2 is a cross-section in a direction normal to the insulators 4, in which the bar has a substantially square cross-sectional area and the sheath a circular cross-sectional area, but it will be understood that this is by way of example only and that the bar and sheath could have been given a different contour. Also illustrated by way of example are four insulators a, b, c and d supporting the bar, but a different number of these insulators could be used.
  • Each insulator has a base A fixed on a flange A integral with the sheath.
  • An insulator member B of conventional ceramic material has one of its ends fixed in the base A and carries at its other end a device C for supporting the bar.
  • This device comprises a shoe C sliding in a drum C with the interposition of a compression spring R.
  • the device C is received in the insulator member B through the agency of a ball-joint C and is retained in said member B by a simple ring 0., of flexible rubber or any other elastic material.
  • the shoe C has a curved face E in contact with the bar, as shown on FIG. 3 which is a longitudinal view thereof. Owing to this curved contour E and to the provision of the device C in accordance with FIG. 2, the bar is able to be displaced relative to the sheath, the device C then assuming an inclined position as shown in FIG. 4, whilst the spring R permanently maintains the bar supporting action of the shoe C
  • FIG. 2 illustrates moreover the possibility of inserting, or removing, an insulator assembly through the sheath wall, and such operation could even be effected in the live condition of the installation.
  • the sheath itself is carried by supports 5 and 6 on which it is slidable to allow for its free expansion and to this end the sheath includes suitably dimensioned shoes normal to the supports.
  • the sheath In order to obtain the longitudinal fixed point F it is sufficient to immobilize a normally free assembly such as 5 by suitably disposing stops T integral with the sheath.
  • An arrangement for fixing an electric bar in a metallic sheath in an insulating manner, in which the bar can be displaced longitudinally relative to the sheath under the effect of thermal expansion comprising a metallic sheath provided with openings of predetermined size, an electric bar within said sheath, and means including a plurality of insulators provided with flanges supporting said bar within said sheath to enable longitudinal displacement of said bar relative to said sheath, the insulators carrying the bar being positioned in the said openings formed in the sheath and being retained therein by a respective flange larger in diameter than the sheath opening and placed on the outer surface of the sheath, whilst the remaining portion of the insulator is so dimensioned as to be able to pass through the sheath opening.
  • An arrangement for fixing an electric bar within a sheath in an insulating manner, in which the barcan be displaced longitudinally relative to the sheath under the effect of thermal expansion comprising sheath means provided with apertures of predetermined size, electrically conductive bar means within said sheath means, and insulating means supporting said bar means in an insulating manner with respect to said sheath means including a plurality of insulating members, each insulating member having a first portion of cross section smaller than said predetermined size to enable introduction thereof through a respective aperture and a second portion of cross section larger than said predetermined size and serving as external abutment so as to enable complete assembly and disassembly of a respective insulating member from the outside of said sheath means, each second portion of a respective insulator member being provided with inwardly facing abutment surfaces engaging substantially complementary outwardly facing surfaces provided on said sheath means, and resilient means operatively associated with a respective insulating member and interposed between a respective insulating member and the bar
