Embodiment Construction

[0016] The present invention will be further described below in conjunction with accompanying drawing.

[0017] figure 1 It is a schematic diagram of a six-interval high-voltage transmission line anti-wind-induced oscillation wire spacer of the present invention. The spacer generally consists of a circular plate frame 1, six clamps 2 evenly distributed on the circumference of the frame, and an anti-vibration hammer assembly 11 located on the central axis of the frame 1. in:

[0018] Circular flat frame 1 is made up of two flat plates of the same shape (as figure 2 shown).

[0019] Each wire clamp 2 is made up of the clamp claw 3 of the front section, the damping rod 4 of the middle section and the seat cover 5 of the rear section. The damping rod 4 consists of a Figure 6 The shown stepped shaft 6 is composed of springs 71 and 72 respectively sleeved at both ends of the stepped shaft and a spring sleeve 8 . The front and back sections of the step shaft 6 are of unequal ...

Abstract

The invention discloses a wire spacer for preventing wind-induced vibration of a high-voltage power transmission line. The wind spacer comprises a frame and a plurality of cable clamps evenly distributed on the circumference of the frame, wherein the cable clamps consist of wire blocking claws, vibration damping rods and socket sleeves; each vibration damping rod consists of a step shaft, two springs respectively sleeved at two ends of the step shaft and a spring sleeve; the front section and the rear section of the step shaft are different in length; one end of the sleeve is a tightening hole, the sleeve is sleeved on the long shaft rod and is in clearance fit with the long shaft rod, the other end of the sleeve is fixedly connected with the socket sleeve; the long shaft rod end of the step shaft is connected with the handle part of the wire blocking claw; the short shaft rod end of the step shaft has a section of axial movement clearance in the sleeve; the tail end of the socket sleeve is hinged with the edge of the frame. The wind spacer can resist high wind in different directions, prevent wires from vibrating, and also can effectively reduce the vibration frequency and intensity of wires, even if the wind speed reaches about 25m/s.

Description

technical field [0001] The invention relates to a spacer for maintaining the spacing of parallel wires on a high-voltage transmission line, in particular to a wire spacer with anti-wind-induced vibration. Background technique [0002] The faults of overhead transmission lines are mostly caused by wind-induced line oscillation. Wind-induced oscillation damages transmission lines in addition to phase-to-phase flash tripping and arc burns. More importantly, it causes conductors, connecting parts and iron towers to bear large dynamic loads. When the load exceeds a certain limit, the relevant components will be damaged. damage, which seriously threatens the safe and stable operation of the power grid. With the development of large cross-section and multi-split overhead transmission lines, accidents caused by wind-induced vibrations are frequent. Although there are many wire spacers against wind-induced vibrations, they are only suitable for overhead transmission lines in areas w...
