Description

Technical Field

[0001] The utility model relates to the technical field of power transmission line grounding devices, and in particular to a novel transmission line tower graphene grounding body and round steel grounding down conductor connection device. Background Art

[0002] Since the application of graphene grounding bodies in power transmission line grounding devices, the connection devices of graphene grounding bodies have also been widely used. Among them, there are two common ways to connect graphene grounding bodies and round steel grounding down conductors. One is to bind the graphene grounding body and the round steel grounding down conductor by winding the graphene binding wire; the other is to weld the round steel grounding down conductor with a metal clamp, and then fix the graphene grounding body with the metal clamp.

[0003] The graphene grounding body and the round steel grounding down conductor are bound by a graphene binding wire. Although the conductivity is good, the mechanical strength is insufficient, and the binding wire may break during long-term operation. When the binding wire breaks, the connection between the graphene grounding body and the round steel grounding down conductor decreases, affecting the conductivity between the graphene grounding body and the round steel grounding down conductor, thereby increasing the grounding resistance of the transmission line tower and reducing the lightning protection reliability of the transmission line tower.

[0004] The graphene grounding body is connected to the round steel grounding lead by a metal clamp, which not only has good conductivity but also high mechanical strength. However, there is a potential difference between the graphene grounding body and the metal clamp. At the same time, long-term operation in the soil will cause serious corrosion of the metal pressure plate, resulting in poor connection between the graphene grounding body and the metal clamp, which will also increase the grounding resistance of the transmission line tower and reduce the reliability of lightning protection of the transmission line tower.
