Abstract

The invention discloses a protection device for the connection between a grounding body and a pole tower, which includes an inner hinge and an outer hinge. The hinge is a hexahedron sleeve with a side opening and no bottom surface. The top surface of the inner hinge is provided with a shaft pin on the edge away from the side of the opening, and the two ends of the upper edge of the opening side of the outer hinge are provided with shaft pin holes. In the pin hole of the outer hinge. Installing a protection device on the ground connection part can ensure that the connection part between the ground body of the overhead transmission line and the tower is not affected by the external environment, and the protection device can be opened flexibly, which can reduce the workload of line ground resistance measurement and ensure that the ground resistance value is not affected .

Description

technical field [0001] The invention relates to a protection tool on a power transmission line in a power system, in particular to a protection device for the joint between a grounding body and a tower. Background technique [0002] The tower grounding device of the transmission line is an important part of the transmission line. It is the general name of the grounding body and the grounding downconductor. Its function is to ensure that the lightning current can reliably leak into the ground, protect the insulation of the line equipment, reduce the lightning tripping rate of the line, and improve the operation reliability. And avoid personal injury caused by step voltage. It is an effective measure to reduce the lightning trip rate of transmission lines to carry out standardized management and maintenance on the grounding devices of transmission line poles and towers, and to ensure the integrity of the grounding devices, while reducing the grounding resistance of the groundi...
