SU11010A1 - Device for protecting high-voltage transmission towers against torsional stresses - Google Patents

Description

It is known that, in high-stress doe, such as breaking a wire or loading it with ice on a one-sided load, winding up the wires, which inform the support non-rotating non-tensions, when the wire is broken or when it is unilaterally loaded with ice. The proposal to play these rotating joists of cables attached to the end of the beams rigidly connected to the support does not always guarantee the complete release of the supports from the action of these moments, due to their own stretching in the cables, which can be very significant with a large distance between the supports.

The proposed invention was not intended to eliminate this disadvantage, by cumulatively using separately already known two-children, pivotal ropes, mounted on supports, to pull their ends.

In FIG. 1 depicts a support with a single beam; FIG. 2 with two; FIG. 3 is a top view of the supports connected by intersecting cables; FIG. 4 - the same, so with ropes, on a part of the span, going to the paradels).

The support 8 shown in FIG. 1, is provided with a horizontally rotatable beam 9, which supports three pin insulators and is connected to the crosscut of an adjacent support with tension cables

10 and 10. In FIG. 2 shows the support

11 with two swiveling crossbeams 12 and 13, connected with cables 14, 15 and 14, 15, the latter being fixed at one common point 16. The cables connected with Eontsan traverse can fasten (Fig. 3) and at crossing points 17 rigidly interconnected, as a result of which, when a cable is broken, the winding part of the binding system will still perceive the resulting torques. Cables can also be interconnected at two points 18 and 19 (Fig. 4), and these points, in turn, are connected by a single or double cable.

Looking at the need, all the traverses, or part of them, can be lovorized, and all or part of the traverses, respectively, can be tied to the wires. As shown in FIG. 2, it is possible, instead of associating each traverse with a corresponding traverse of the full support.

bring the tension ropes to the same common point where they are firmly connected to each other, and this common point to be connected with a double cable to each other.

The subject of the patent.

1. Device for protection of high-voltage transmission line poles against the effect of twisting lees, characterized by aggregate pressure: a) are turning in the horizontal front plane of two shoulders, fixed directly on the support, and b) two strapping cords of ectra beams of cables rigidly fastened with each other another in the span between the supports in one sludge in several places, which cables are either intersecting with each other (Fig. 3), or are directed to the part of the span parallel to each other (Fig. 4).

/}. Modification of the device described in paragraph 1, characterized in that the two cables in the span between the seats And the fasteners are replaced by one cable (Fig. 4).
