Description
Technical field
The present invention relates to Overhead power distribution equipment technical field more particularly to a kind of high-altitude electric power based on multispan Anti-vibration system
Cable corona-proofing device.
Background technique
The outer surface of cable is easy to gather a large amount of water mist in rainy days, and water mist can further be gathered into water droplet, water droplet again
Can gradually be elongated under the action of gravity and electric field force is in tip, and charge density of the water droplet at tip is maximum, electric field strength
Also very big, when electric field strength, which reaches, is enough to make air ionization, the air around water droplet will be made to generate sharp electric discharge, electricity occurs
Dizzy, corona discharge is huge for the energy loss of overhead cable, can only be by making cable surface more light to reduce this loss
Cunning etc. changes the mode of cable structure to reduce corona phenomenon, but cable is difficult to protect always under the long-term sour corrosion of rainwater
It holds smooth, and for the cable after having assembled, lacks corresponding method to reduce corona.
And in the conventional technology, overhead cable fatigue fracture under the vibration of wind-force in order to prevent, usually setting vibrationproof
Hammer, when high voltage overhead cable vibrates under the action of the forces of the wind, cable drive damper do forced vibration, when wind-force gradually
When increase, until the vibration frequency of cable is identical as the intrinsic frequency of damper, resonance, the Absorption Line in resonance occur for damper
Cable is up to 90% vibrational energy, and this energy is converted into thermal energy harmony can consume, and cable is greatly reduced in this process
Vibration, thus the liquid on cable is more difficult to that adhesion strength is overcome to be thrown out of.
In summary reason, thus be badly in need of a kind of device and the water droplet that cable surface gathers is eliminated, it reduces corona and puts
Electricity.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
Embodiment one
Referring to figs. 1 to 3, a kind of high-altitude electric power cable corona-proofing device based on multispan Anti-vibration system, including fixture 1, hang
Block 2, elastic rod 3 and pendulum 4, the bottom end of fixture 1 are fixedly connected with hanging block 2, and the bottom end of hanging block 2 is fixedly connected with normal thereto set
The elastic rod 3 set, the two sides of elastic rod 3 are fixedly connected to pendulum 4, and outer surface end of the pendulum 4 far from elastic rod 3 is fixed to be connected
It is connected to rope body 5, it is equidistant on body 5 of restricting to be fixedly installed at least one cleaning piece 6；
Cleaning piece 6 includes that lantern ring 61, first drains part 63 and the second drainage part 66, and the middle part of lantern ring 61 axially opens up wired
Cable jack 62 offers the notch 67 for inlet wire on the side wall of lantern ring 61, and being provided on the outer surface of notch 67 can be by notch
67 closed Fasteners 7.
Specifically, referring to Fig. 3, Fastener 7 is made of fixed ring 71 and 72 two parts of Saw blade, and fixed ring 71 and sawtooth
Item 72 is respectively fixedly connected in the outer surface two sides of notch 67.Cable is placed in cable jack 62 by notch 67, Saw blade 72
Be inserted into fixed ring 71, and be stuck in fixed ring 71 by serrated vertical face by sawtooth inclined-plane, it is notable that cable and
Fixation between lantern ring 61 should prevent from excessively tightening there are certain analysis.
The upper end of first drainage part 63 is smooth plane, and the lower end of the first drainage part 63 is the cambered surface 65 being obliquely installed,
It is equidistant on first drainage part 63 to offer multiple through-holes 64 vertically,
Second drainage part 66 is pyramidal structure, and one end that the second drainage part 66 is relatively large in diameter is fixedly connected on 61 bottom of lantern ring
End and the side for draining part 63 close to first.
When high voltage overhead cable vibrates under the action of the forces of the wind, cable drives fixture 1, hanging block 2,3 and of elastic rod
Pendulum 4 does forced vibration, to substantially eliminate cable vibration, this is the prior art, no longer superfluous herein.
When pendulum 4 vibrates, band running rope body 5 is moved in upper and lower swing, and rope body 5 pulls multiple cleaning pieces 6 in cable
Outer surface move back and forth, and the first breaking-drop for will gathering of drainage part 63 in this reciprocating motion, broken water mist quilt
Enter the lower surface of the first drainage part 63 through hole 54 under the action of tension and gravity, and slides to second along cambered surface 65 and draw
It flows at part 66, and falls in Qi Jianchu, and the water mist that cable surface is broken up, due to having bigger surface area, so as to quilt
It quickly air-dries, greatly reduces cable because of electric energy loss caused by corona.
Embodiment two
Referring to Fig. 4, embodiment two on the basis of example 1, further increases its ability for assembling water droplet, specifically
Structure is as follows:
Lantern ring 61 offers recess 11 on the side inner wall of the second drainage part 66, and lantern ring 61 is far from the second drainage part 66
