The utility model relates to a six-division double-pendulum anti-galloping damping spacer rod. The six-division double-pendulum anti-galloping damping spacer rod comprises a compact type six-division damping spacer rod. The compact type six-division damping spacer rod is a regular hexagon; a symmetrical inverted Y-shaped yoke plate is arranged at one edge of the compact type six-division damping spacer rod, the top part of the inverted Y-shaped yoke plate is fixedly connected with the compact type six-division damping spacer rod, a pendulum is respectively arranged at the end parts of two branches at the lower part of the inverted Y-shaped yoke plate, and the symmetrical line of the inverted Y-shaped yoke plate is penetrated through the centroid of the compact type six-division damping spacer rod. As two pendulums are symmetrically arranged on the six-division double-pendulum anti-galloping damping spacer rod, when the six-division double-pendulum anti-galloping damping spacer rod is arranged on an overhead transmission line, parameters such as the torsional rigidity, the torsional inertia and the like of a six-division conductor system of a compact type line can be changed; therefore, the effect of preventing the galloping of the transmission line can be achieved.
Description
Technical field
The utility model is the damping conductor spacer that is used for overhead transmission line about a kind of, relates in particular to a kind of six division double pendulum anti-dance damping conductor spacers.
Background technology
Compact transmission line can improve the nature transmission power, reduces the circuit width of corridor, has very high social economic value.But because compact transmission line has compressed the phase conductor spacing, compact transmission line is waved can cause than common power transmission line and is waved more serious consequence.When common six division damping conductor spacers are installed on the transmission line, make six roots of sensation sub-conductor in the same phase conductor keep certain relative position to satisfy electric property, under the situation of short circuit, the unlikely generation collision that attracts each other between sub-conductor in the lead, though or the attraction that causes moment is collided, but accident can return to normal condition after eliminating, and this kind conductor spacer is installed damping element in joint, wire clamp simultaneously, can suppress bundle conductor aeolian vibration and subspan oscillation to a certain extent.But the whole torsional rigidities that the six-multiple conductor of six division damping conductor spacers has been installed are less than the torsional rigidity of single sub-conductor, when circuit produced icing or appropriate situations such as wind excitation and takes place, the possibility that bundle conductor is waved was greater than the possibility that single sub-conductor is waved.Therefore, taking effective and efficient manner to prevent and treat waving of compact transmission line is a quite urgent problem.
It is generally acknowledged that the generation of transmission line galloping depends primarily on " three elements ", i.e. " the inhomogeneous icing of conductive line surfaces ", " suitable wind excitation " and " the easily line construction parameter of dance ".Wherein " the easily line construction parameter of dance " is the essential condition that circuit is waved.Thus, if can change the line construction parameter, thereby the power performance of change circuit reduces the possibility that circuit is waved, and this has tangible positive effect to the control of waving.
The utility model content
The purpose of this utility model is to provide a kind of six division double pendulum anti-dance damping conductor spacers, by the parameters such as torsional inertia of this double pendulum anti-dance damping conductor spacer with the six-multiple conductor system of change compact transmission line is installed, reach the purpose that prevents transmission line galloping.
The purpose of this utility model is to realize like this, a kind of six division double pendulum anti-dance damping conductor spacers, described six division double pendulum anti-dance damping conductor spacers comprise a compact six division damping conductor spacers, these compact six division damping conductor spacers are a regular hexagon structure, " people " font yoke plate that wherein is provided with symmetry on one side at these compact six division damping conductor spacers, fixedly connected with compact six division damping conductor spacers in the top of being somebody's turn to do " people " font yoke plate, the end of two branches in described " people " font yoke plate bottom is respectively equipped with a pendulum; The line of symmetry of described " people " font yoke plate is by the centre of form of described compact six division damping conductor spacers.
In a better embodiment of the present utility model, described pendulum is a solid construction.
In a better embodiment of the present utility model, described pendulum is made by cast iron or cast steel.
In a better embodiment of the present utility model, described pendulum surface galvanizing by dipping.
In a better embodiment of the present utility model, described pendulum is provided with a lug, and this lug is bolted to connection with " people " font yoke plate bottom.
In a better embodiment of the present utility model, described pendulum is a spheroidal, oval spherical or cylindrical.
In a better embodiment of the present utility model, the hexagonal position of described compact six division damping conductor spacers is respectively equipped with a damping wire clamp.
From the above mentioned, owing to be arranged with two pendulums on the six division double pendulum anti-dance damping conductor spacers of the present utility model, when being arranged on this six divisions double pendulum anti-dance damping conductor spacer on the overhead transmission line, can change parameters such as the torsional rigidity of six-multiple conductor system of compact line and torsional inertia, thereby change the dynamic characteristics of wiring system, therefore, can reach the effect that prevents transmission line galloping.
