The invention relates to electric power industry, namely to the design of ballasts installed on overhead transmission lines with phase conductors split into several components.

The purpose of the invention is to provide ease of installation, compact design, expanding the range of weight control of the goods, improving the reliability of fastening, as well as eliminating p-damage to the lower wire of the split phase with an odd number of components.

Figure 1 shows the ballast, front view; fig 2 is the same, view of the cables (along the wires of the split phase)

The ballast for overhead lines, electrical transmissions with phase conductors split into several components 1, contains weights 2 with an aperture 3 fixed on the supporting element parallel to each other, and a locking element with fasteners 4,

The bearing element is made in the form of a beam-channel 5, located along the axis 6 of the split phase, and two brackets, each of which is made in the form of Two vertical rods 7 with a transverse stiffening rib 8 between them.

In this case, the weights 2 are fixed on the carrier beam-channel 5 IU / vdu by brackets, which by one ends 9 are suspended through plates-clamps 10 to wires 1, and by other ends 11 are hinged (hinge 4) to

Weights 2 are made in the form of plates of a segment shape with an oval part at the top, and the weights: there are depressions 12 in order to prevent damage to the lower wire 1 of the split phase with an odd number of wires in case of its possible tightening

1J wires and others are hinged to the floor of the beam-beam 5, the goal is achieved by the presence of the beam-beam, the presence and performance of brackets and the location of the goods. 1 hp f-ly 5 2 ill.

The locking element with fastener 4 is also a limiter fixing the position of the weights 2 relative to the brackets (vertical rods 7)

with a full set of weights 2 If the number of weights 2 is chosen to be less than the maximum, then for fixing relative to each other, in the weights 2 there will be holes where

bolts (not shown) securing the load plates 2 to each other.

The installation of the ballast is carried out in the following sequence.

After the wires on the ground are laid on the razkatochnyh rollers in the supporting clamps, the rastedelennaya phase is lifted above the ground to a height of about 1 m. Then they are mounted on the wires to

given distance from each other brackets. With the help of a lifting mechanism, a supporting beam-channel 5 with installed and fixed weights 2 is inserted into the split phase

and alternately fastened to the ends of the 11 vertical rods 7 by means of a locking element with fasteners 4. After this, the dies 10 are finally tightened and the insulating suspension is attached to the overhead power line support.

Industrial use of ballast, the proposed design allows to increase the reliability of the lines, so

as the execution of the bearing element in the form of a channel beam and two brackets makes it possible to install at least four dies, i.e. to reserve the attachment of ballast when any clamping plate is damaged from, for example, bending forces, which, in turn, are reduced by hinging the brackets to the supporting beam-channel.

In addition, the installation of loads parallel to each other along the axis of the split phase provides the possibility of fixing them with a given (optimal) quantity (the ballast does not violate the phase geometry, since it is completely inside it).

In order to eliminate the disturbance of the geometrical dimensions of the split phase, due to the pushing of the wires when it is installed next to the ballast, it is possible to install a standard distance multipath strut.
