When wind is when becoming on the overhead transmission line of on-circular cross-section because of icing, can produce certain air force, easily bring out circuit and produce a kind of approximately 0.1～3 low frequency of Hz, the self-oscillation of large amplitude, on vibration shape, show as and in a span, only have one or a few half-wave, be called and wave.Wave overhead transmission line very harmfully, can cause line flashover, tripping operation, shaft tower bolt looseness, come off, gold utensil and insulator can occur when serious and damage, disconnected strand of wire, broken string, even fall tower, thereby cause the generation of great power grid accident.Therefore it is very necessary, taking certain Anti-Oscillation Measures.
In existing transmission line, used various Anti-galloping devices, common is composite alternate interval rod, has certain Anti-galloping effect.At present, these composite alternate interval rods are general adopts common rod insulator to be connected with common wire clamp gold utensil, can only limit to a certain extent the generation of waving, and not good enough to suppressing aeolian vibration and subspan oscillation effect.When meteorological condition is very severe, once line oscillation occurs, common composite alternate interval rod lacks the approach that discharges line oscillation energy, cannot eliminate fast line oscillation.Meanwhile, wave for a long time and also easily cause cable clip bolt to become flexible, weigh wounded the shortcomings such as circuit, need periodic maintenance.Such equipment has potential potential safety hazard, will directly affect transmission line safe and stable operation and increase maintenance cost.
Summary of the invention
For overcome that prior art deposits defect, the invention provides the moving conductor spacer of a kind of spring shock absorption type interphase anti-galloping, object is to wave with subspan oscillation and in meteorological condition the approach that provides quick release to wave energy while waving is very badly provided for effective limiting circuitry, thereby guarantees power system safety and stability operation and reduction O&M cost.
To achieve the above object of the invention, the technical solution adopted in the present invention is as described below:
Type interphase anti-galloping moves a conductor spacer, is by connecting gold utensil, to connect Anti-galloping vibration absorber at the middle part of two inter-phase spacer insulators; The outside two ends of two inter-phase spacer insulators are connected with wire clamp gland by connecting gold utensil respectively.
On described wire clamp gland, be respectively equipped with wire clamp gland ears structure or connect gold utensil monaural structure.
Described Anti-galloping vibration absorber is positioned at the end of two inter-phase spacer insulators.
Described Anti-galloping vibration absorber is in dampener sleeve shell, to be provided with the guide post with protruding button baffle plate, on guide post, be set with damping spring, one end of guide post is connected with the anti-icing water cover plate of dampener sleeve, between the anti-icing water cover plate of dampener sleeve shell and dampener sleeve, is provided with damping seal rubber cushion; The two ends of dampener sleeve shell respectively be connected gold utensil and be connected.
The radius of described dampener sleeve shell is less than the radius of insulator umbrella.
One end of described damping spring is connected with dampener sleeve shell inwall, and the other end of damping spring is connected with the protruding baffle plate top of buckleing on guide post.
Described protruding button baffle plate is circular, and radius is less than the internal diameter of damping damping spring.
The present invention is the moving conductor spacer of a kind of spring shock absorption type interphase anti-galloping, its effective effect is: this invention has adopted damping spring shock-damping structure, damping spring has larger extendable room in dampener sleeve shell, can bear pressure or pulling force, the bootable inter-phase spacer of guide post is along spring shaft to activity, and protruding button baffle plate can organize damping spring to bear undue pulling force.After this damping spring shock-damping structure can effectively improve wire icing, moment of torsion increases the distribution of force to wire clamp junction, effectively limiting circuitry aeolian vibration and subspan oscillation very badly cause while waving and provide quick release to wave self-oscillation energy in meteorological condition, effect is remarkable.Meanwhile, the present invention has simple and practical, easy for installation, cheap, non-maintaining feature, is with a wide range of applications.
