Problems solved by technology
However, the above-mentioned first technical solution has the problem that the cost of the transmission line and the width of the corridor will be greatly increased
The existence of the second method above will restrict the movement of wires and fittings. Under the influence of long-term wind vibration, the movement of wires and fittings is susceptible to fatigue damage. Therefore, the use of the second method above has potential safety hazards within the engineering allowable range

The invention discloses a power transmission line anti-windage yaw pole based on a flexible composite material, and specifically designs a power transmission line anti-windage yaw pole structure; the power transmission line anti-windage yaw pole comprises a pole body; two ends on the top of the pole are respectively connected with a wire cross-arm; the power transmission line anti-windage yaw pole also comprises flexible stop cables; the flexible stop cable comprises a joint-tower extension fitting, a first flexible composite insulator with an umbrella skirt, a flexible composite insulator with no umbrella skirt, a second flexible composite insulator with an umbrella skirt, a first connecting fitting, a stay cable, a second connecting fitting, a spring and a third connecting fitting connected in sequence from top to bottom; the flexible stop cable is respectively connected between the empty end of each wire cross-arm and the middle portion of the pole body; the joint-tower extension fitting is connected with the empty end of the wire cross-arm; the third connecting fitting is connected with the middle portion of the pole body. The power transmission line anti-windage yaw pole based on the flexible composite material can prevent existing wire windage yaw flashover problems on the pole in a project, thus improving the power transmission line safety reliability.
Description
technical field [0001] The invention relates to a structure of a windproof deflection tower for a power transmission line, in particular to a windproof deflection tower for a power transmission line based on flexible composite materials. The invention also relates to the construction method of the flexible composite material-based transmission line anti-wind deflection pole tower. Background technique [0002] The single-circuit straight poles and towers of UHV / EHV overhead transmission lines in my country mostly adopt wine glass or cat head structure, and the side conductors mostly use I-type insulator strings. Under extreme windy conditions, the above-mentioned existing I-type insulator strings are prone to deflection, which makes the existing UHV / UHV overhead transmission line straight poles vulnerable to extreme weather, so that the side of the UHV / UHV overhead transmission line Wind deflection flashover accidents of phase conductors show a high incidence trend.
