Abstract
1396750 Conductor spacers SAS OFFICINE MECCANICHE INNOCENTE RIGANTI DI INNOCENTE E FRANCO RIGANTI 23 Aug 1972 [7 Sept 1971] 39265/72 Heading H2C [Also in Division F2] A spacer for conductors of overhead lines consists of a rigid support frame 4 with at least two arm members 1, each of which comprises a ring 2 and lower portion 9 which holds at least one conductor in clamp 9a. The arm 1 is movably mounted on frame 4, by means of bar 5, of polygonal, (in this embodiment, square) prismatic shape. The internal surface 2a of ring 2 has the same number of sides as bar 5 and the vertices thereof are smoothed into parabolas 3, and mounted opposite each side of bar 5 by means of resilient elastomeric rubber members 6, which are pre-compressed to some extent, and held therein by plates 11. Bar 5 is mounted in frame 4 by means of bolts (5a) (Fig. 2, not shown), coaxially with its centre of symmetry. The arm 1 may move, under forces directed on conductor (10), relative to the bar 5, in a plane perpendicular to the axis of bar 5, in the direction of the same axis, and also rotationally along an axis perpendicular to the axis of bar 5, and is resiliently restrained by the compression of rubber members 6, and damped by the frictional effects created therein. To prevent the arm 1 fouling the support member 4, arm 1 includes, stop 7 which may come into abutment with resilient stops 8 on the member 4, and further includes grooves 12 in ring 2 to prevent bar 5 contacting same. Rubber members 6 are cylindrical but may be, e.g. spherical &c. The spacer may have provision for 2, 3 or 4 conductor bundles (10) as illustrated in Figs. 3, 4 and 5 (not shown). In practice, the spacer is placed at a vibration anti-node on a suspended line, such that small vibrations are damped and large scale vibrations of the line receive maximum damping, the spacer being operable in all directions of motion.
