Background technology
When in wind to the overhead transmission line become on-circular cross-section because of icing, certain air force can be produced, easily induction circuit produces the low frequency of a kind of about 0.1～3 Hz, the self-oscillation of big amplitude, vibration shape shows as only one of which or a few half-wave in a span, is referred to as waving.Wave overhead transmission line very harmful, line flashover, tripping operation, shaft tower bolt looseness can be caused, come off, gold utensil and insulator time serious, can be occurred to damage, wire strand breakage, broken string, the most tower, thus cause the generation of great power grid accident.Therefore, it is the most necessary for taking certain Anti-Oscillation Measures.
Existing transmission line of electricity employed various Anti-galloping device, common for composite alternate interval rod, there is certain Anti-galloping effect.At present, these composite alternate interval rods typically use common rod insulator and common wire clamp gold utensil to connect, and can only limit the generation waved to a certain extent, and to suppression aeolian vibration and subspan oscillation less effective.When meteorological condition is the most severe, once line oscillation occurs, and common composite alternate interval rod lacks the approach of release line oscillation energy, it is impossible to quickly eliminate line oscillation.Meanwhile, wave for a long time and be also easy to cause cable clip bolt to loosen, weigh the shortcomings such as circuit wounded, need periodic maintenance.Such equipment has potential potential safety hazard, will directly affect transmission line of electricity safe and stable operation and add maintenance cost.
Summary of the invention
For overcoming what prior art was deposited defect, the present invention provides a kind of spring shock absorption type interphase anti-galloping to move conductor spacer, purpose is in order to effective limiting circuitry is waved and subspan oscillation provide quickly release to wave the approach of energy when meteorological condition the most badly causes and waves, so that it is guaranteed that power system safety and stability runs and reduces O&M cost.
To achieve the above object of the invention, the technical solution adopted in the present invention is as described below:
A kind of spring shock absorption type interphase anti-galloping moves conductor spacer, is by connecting gold utensil connection Anti-galloping damper 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 connection gold utensil respectively.
It is respectively equipped with wire clamp gland ears structure on described wire clamp gland or connects gold utensil monaural structure.
Described Anti-galloping damper is positioned at the end of two inter-phase spacer insulators.
Described Anti-galloping damper is to be provided with the guide post with cam baffle plate in dampener sleeve shell, damping spring it is set with on guide post, one end of guide post connects dampener sleeve anti-icing water cover plate, is provided with damping seal rubber cushion between dampener sleeve shell and dampener sleeve anti-icing water cover plate；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 cam baffle plate top on guide post.
Described cam baffle plate is circular, and radius is less than the internal diameter of damping damping spring.
The present invention is that a kind of spring shock absorption type interphase anti-galloping moves conductor spacer, its effective effect is: this invention have employed damping spring shock-damping structure, damping spring has bigger extendable room in dampener sleeve shell, allowable stress or pulling force, the bootable inter-phase spacer of guide post is the most movable along spring, and cam baffle plate can organize damping spring to bear undue pulling force.After this damping spring shock-damping structure can be effectively improved wire icing, moment of torsion increases the distribution of force to wire clamp junction, can effectively limiting circuitry aeolian vibration and subspan oscillation provide quickly release to wave self-oscillation energy when meteorological condition the most badly causes and waves, effect is notable.Meanwhile, the present invention has simple and practical, easy for installation, cheap, non-maintaining feature, is with a wide range of applications.
