A lightning protection power tower grounding and current diversion structure

Abstract

This application relates to the field of lightning protection technology for power facilities, and in particular to a grounding and current-diverting structure for power towers to prevent lightning strikes. The structure includes a cylindrical body, a traction mechanism, and a first fixing mechanism. The traction mechanism is located inside the cylindrical body and can connect to the grounding wire and be driven into the ground. The cylindrical body is fixed to the ground by the first fixing mechanism, which prevents the cylindrical body from tipping over. Through the synergistic effect of the multi-angle fixing rods (15°–45° oblique anchoring) of the first fixing mechanism and the adjustable support legs (0°–90° rotation + telescopic adjustment) of the second fixing mechanism, a composite anti-overturning structure of "spatial radial anchoring + dynamic triangular support" is formed. This structure can resist strong wind loads and the instantaneous impact force of lightning strikes. The tilt angle of the grounding pile can be controlled within 1° (compared to 5°–10° for traditional single piles), significantly reducing the risk of increased mechanical stress and contact resistance in the grounding wire caused by pile tilting.
