Abstract

The present invention relates to a connector and connection method used for connecting a plurality of graphite composite grounding bodies. The connector comprises two conductive clamping plates, and bolts, nuts and spacers which are used to connect the two conductive clamping plates fixedly. The two sides of the conductive clamping plates are respectively equipped with a plurality of fixing holes which are arranged at equal intervals and through which the bolts can penetrate, and the fixing holes at the two sides of the conductive clamping plates are in one-to-one correspondence respectively. The two conductive clamping plates are used to clamp the graphite composite grounding bodies by the cooperation of the bolts, the nuts and the spacers, and connect the plurality of graphite composite grounding bodies electrically. The connector of the graphite composite grounding bodies can be widely used in the connection field of the graphite composite grounding materials, can solve the problems that the conventional graphite composite grounding bodies can not be connected by the electrowelding, gas welding, heat-released jointing, etc., can connect the graphite composite grounding bodies more stably, is large in connection intensity and low in connection resistance of connection points, and can satisfy the actual grounding construction demands.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a connector and a connection method for a graphite composite grounding body. Background technique [0002] The grounding device of the power system is an important facility to ensure the reliable grounding of power equipment and protect the personal safety of power construction personnel, and it is also an important means of lightning protection for power systems. At present, the grounding materials of common power systems are mostly made of round steel, flat steel, galvanized steel and other steel materials, and some important power hubs also use expensive copper materials as grounding materials. In recent years, copper-clad steel grounding materials have also been tried in some grounding occasions. The actual operation experience shows that the copper metal grounding material has better corrosion resistance. The corrosion resistance of copper-clad steel grounding materials depend...
