Abstract
The invention belongs to the technical field of safety protection for overhead power transmission lines, and particularly relates to a rotary efficient damping anti-galloping spacer with wire clamps. The anti-galloping spacer comprises a spacer body frame. The spacer body frame is of a regular polygon structure or a line structure, and a rotatable sleeve is connected to each of vertex angles or two ends of the spacer body frame; a slide groove is arranged in each sleeve, an end cover with a hole is fixedly connected to a free end of each sleeve, the wire clamps are mounted in the sleeves, and one end of each wire clamp is matched with the corresponding slide groove via a slider; springs are respectively mounted in each sleeve and are positioned on two sides of the slider of the corresponding wire clamp; and the sliders of the wire clamps are hollow, and a short pin is arranged in each slider and is fixedly connected with the corresponding sleeve. The anti-galloping spacer has the advantages that unevenness of icing can be eliminated or reduced via swinging of the rotary wire clamps; and as vibration damping is improved, vibration energy generated by wind excitation can be effectively absorbed, galloping occurring conditions are destroyed, and galloping is stopped.
Description
Technical field
The invention belongs to overhead transmission line safety protection technique field, particularly a kind of cable clip rotary type Efficient Damping Anti-swing spacing bar.
Background technology
At present, cable clip rotary type anti-bouncing spacer can make the parton wire can axial-rotation in the overhead transmission line, and wire icing is tending towards evenly, thereby suppresses the generation of waving; But present cable clip rotary type anti-bouncing spacer structural damping is low, can not effectively absorb the vibrational energy that the wind excitation produces, even wire icing is tending towards evenly, the possibility of waving is still very high, thereby has reduced to a great extent the anti-dance effect of cable clip rotary type conductor spacer.
Summary of the invention
The invention provides a kind of cable clip rotary type Efficient Damping Anti-swing spacing bar, can not only eliminate or alleviate by the swing of revolution wire clamp the unevenness of icing, and owing to improved vibration damping, can absorb efficiently the vibrational energy that the wind excitation produces, destruction is waved occurrence condition, thus the generation that inhibition is waved.
The technical solution used in the present invention is:
This Anti-swing spacing bar comprises the conductor spacer body frame, and this conductor spacer body frame is regular polygon structure or linear structure, connects respectively a rotating sleeve at each angle position or the two ends of conductor spacer body frame; In the described sleeve chute is set, the end cap that its free end affixed is with holes, and the wire clamp that an end cooperates with chute by slide block is installed in sleeve; In sleeve, the slide block both sides of wire clamp mounting spring respectively; The slide block of described wire clamp is hollow slide block, and a short pin affixed with sleeve is set in it.
Described sleeve is connected with the conductor spacer body frame by pin.
The slide block of described short pin and wire clamp all is positioned at the middle part of sleeve.
The two ends of described spring are connected with the slide block of sleeve and wire clamp respectively.
The limit number of described conductor spacer body frame is the 3-8 bar.
Beneficial effect of the present invention is:
(1) wire clamp of conductor spacer is radially movable bar, and under spring action, structural damping is large, can effectively absorb the vibrational energy that wind excitation produces, thereby avoids the generation of waving;
(2) during spring generation deformation, improve the natural frequency of anti-dance device, prevent resonance;
(3) variable because of the conductor spacer installation site, thus applicable to the occasion of different interval rod dimensional requirement, have the structure versatility.
