Rotary efficient damping anti-galloping spacer with wire clamps

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 [0001] The invention belongs to the technical field of safety protection for overhead power transmission lines, and in particular relates to a clamp rotary type high-efficiency damping and dance-proof spacer. Background technique [0002] At present, the anti-galling spacer with rotating clips in the middle of the overhead transmission line can make some sub-conductors rotate axially, so that the ice coating on the wires tends to be uniform, thereby suppressing the occurrence of galloping; Low, can not effectively absorb the vibration energy generated by the wind excitation, even if the wire ice tends to be uniform, the possibility of galloping is still high, thus greatly reducing the anti-galling effect of the clamp rotary spacer. Contents of the invention [0003] The invention provides a wire clip rotary type high-efficiency damping anti-dancing spacer, which can not only eliminate or reduce the unevenness of ice coating through the swing of the rotary w...
