Description
Technical field
The utility model relates to Anti-galloping device field, particularly relates to a kind of ultra high voltage eight division electricity transmission line rice word formula decentralized anti-dance mover conductor spacer system.
Background technology
Along with the continuous expansion of power grid construction scale, transmission line disaster accident under field conditions (factors) frequently occurs, waving is exactly wherein comparatively serious a kind of accident, transmission line has the design features such as the division number of phases is many, conductor cross-section is large, span is long, stringing is high, thus more easily wave under the condition of dancing, the consequence that transmission line is waved is extremely serious, line tripping, broken string will be caused, tower may be there is down time serious, even cause regional power grid accident, cause the consequence more serious than general line oscillation.
Because the structural parameters of UHV transmission line are different with the route of power transmission waving characteristic and other type, therefore waving of current UHV transmission line is directed to, main to press down dance measure be that wire clamp can reverse the method such as conductor spacer, two parallel wielded-proof device, in operative practice, serve certain governance role to waving of extra high voltage line.
But current said method all has comparatively significantly shortcoming.
Antiswing device, based on stability anti-dance mechanism, is combined with inter-phase spacer by two parallel wielded-proof device, by increasing system torsional rigidity and moment of inertia, changing the ice wind threshold value that wire is waved, can effectively suppress to wave.But two parallel wielded-proof device being invalid for waving same period of adjacent wires, when waving, makes adjacent wires forced synchronism, waving energy and strengthening, thus larger harm is produced to transmission line and shaft tower.
Wire clamp can reverse the automatic rotation mechanism that conductor spacer utilizes rotatable grip part, sub-conductor is made to achieve freely turning round in certain limit, that suppresses icing accumulated snow on wire to be formed on the one hand is irregularly shaped, the torsion produced by own axes on the other hand changes the windward side of wire, wire icing is made to tend to evenly, weaken aerodynamic load, thus wire is not easily waved.But wire clamp can not suppress to wave generation by torsional mode conductor spacer completely.
Utility model content
The purpose of this utility model is to provide a kind of ultra high voltage eight division electricity transmission line rice word formula decentralized anti-dance mover conductor spacer system, can by the dynamic characteristic differentiation process to multiple fission conductor time span, vibrational energy can mutually be absorbed between each span, thus effectively improve UHV transmission line wave inhibition.
The utility model adopts following technical proposals:
Ultra high voltage eight division electricity transmission line rice word formula decentralized anti-dance mover conductor spacer system, comprise the four groups of anti-dance mover conductor spacers arranged along eight division electricity transmission line axially spaced-aparts, eight division electricity transmission lines, eight wires are along the circumferential direction respectively the first wire to the 8th wire, often organize anti-dance mover conductor spacer and include conductor spacer body frame and two wire clamps, two wire clamps are separately positioned on the two ends of conductor spacer body frame, on the first wire that the two ends of first group of anti-dance mover conductor spacer are separately fixed at eight division electricity transmission lines and the 5th wire; On the second wire that the two ends of second group of anti-dance mover conductor spacer are separately fixed at eight division electricity transmission lines and the 6th wire; On the privates that the two ends of the 3rd group of anti-dance mover conductor spacer are separately fixed at eight division electricity transmission lines and the 7th wire; On the privates that the two ends of the 4th group of anti-dance mover conductor spacer are separately fixed at eight division electricity transmission lines and the 8th wire.
Described wire clamp is bolted on the end of conductor spacer body frame.
The wire that described often group anti-dance mover conductor spacer is all connected with these anti-dance mover conductor spacer two ends is vertical.
The utility model tool has the following advantages:
First, ultra high voltage eight division electricity transmission line rice word formula decentralized anti-dance mover conductor spacer system described in the utility model, decomposed by traditional overall formula conductor spacer, the space that is distributed in of each anti-dance mover conductor spacer forms dispersed placement, destroys between adjacent span and vibrates wave propagation;
The second, because the difference of the sub-conductor spacer of decentralized is arranged, the dynamic characteristic of bundle conductor each span is different, thus energy when can avoid transmission line galloping is strengthened;
3rd, the sub-conductor spacer of decentralized makes the mechanical impedance between each span be in not matching status, and vibrational energy mutually can absorb between each span, effectively inhibits time span vibration;
4th, have employed distributing and arrange the globality destroying guidewire movement, thus realize the off resonance between transverse vibration and twisting vibration.
