Background
With the continuous change of environmental climate, local strong convection weather frequently occurs, and tripping accidents caused by wind deflection influence of the power transmission line frequently occur, so that certain influence is caused on the safe operation of the power transmission line. The windage yaw discharge accidents of the power transmission line caused by strong wind frequently occur, and the reasons are that a large amount of creepage adjustment in the anti-pollution flashover transformation of the line increases the length of a porcelain or glass insulator string, so that the radius of a clearance circle is increased, and the windage yaw discharge resistance is reduced; the composite insulator is widely applied, and the composite insulator is light in weight and poor in wind deflection resistance, so that wind deflection discharge accidents are easy to happen. At present, the common wind deflection prevention measures at home and abroad are as follows: firstly, a heavy hammer is additionally arranged at a lower hanging point of a suspension insulator, secondly, the suspension composite insulation is changed into a V-shaped double hanging point, the first method has the defects that the radius of a clearance circle is increased, the technical performance is not ideal, and the second method has the defects that the number of the composite insulators is doubled after the double hanging point is adopted, the economy is poor, the dry arc distance of the insulators is reduced, and lightning accidents are easy to occur; the comparison document CN203243003U provides a handbag type suspension clamp for preventing wind deflection, but the position of the windproof stay string which is not connected below the suspension clamp hull in the comparison document can only be connected with the lengthened semicircular head bolt above the clamp hull through an LB (Luma-board) connecting plate, and the problems of inflexible rotation and rigid connection of the clamp exist in the connection mode.
