Quick-connection cylinder type connecting part for graphite composite grounding body and application of quick-connection cylinder type connecting part

Abstract

The invention discloses a graphite composite grounding body quick-connecting cylindrical connector and its application, comprising an upper semi-cylindrical body, a lower semi-cylindrical body, a left annular fixing part and a right annular fixing part; an upper semi-cylindrical body and a lower semi-cylindrical body Both have axial through grooves, and the outer surfaces of the upper half cylinder and the lower half cylinder are provided with external threads; the inner edges of both sides of the upper half cylinder and the lower half cylinder are provided with grooves at equal intervals; The inner wall of the ring fixing part and the right ring fixing part are provided with internal threads, the left side of the left ring fixing part is provided with two card slots along the radial direction, and the right side of the right ring fixing part is also provided with two card slots along the radial direction; the upper half cylinder The body is placed on the lower semi-cylindrical body to form an overall cylindrical body, and the left and right annular fixing parts are respectively set on the two ends of the overall cylindrical body. The invention is applicable to the connection of graphite composite grounding bodies, and has simple structure, convenient construction, easy transportation and carrying, no need for heavy tools such as welding, high flexibility, low cost, mass production and broad engineering application prospects.

Description

technical field [0001] The invention belongs to the technical field of lightning protection and grounding for pole and tower grounding grids of overhead power transmission lines, and in particular relates to a graphite composite grounding body fast-connecting cylinder type connector and an application thereof. Background technique [0002] The long-term operation experience of the power system shows that the lightning tripping accident of the transmission line is the main factor causing the outage accident of the transmission line. Although common lightning protection devices such as lightning protection wires and lightning arresters play a good role in lightning protection, the investment is too large and the subsequent maintenance work is heavy. From the perspective of the actual lightning protection effect, reducing the grounding resistance of the transmission line tower grounding grid is the most economical and effective means of lightning protection for transmission lin...

Problems solved by technology

However, as a new type of grounding material, the flexible graphite composite grounding material also encounters some problems in actual construction. For example, the flexible graphite composite grounding material is a non-metallic grounding material, and the connection of its intersection points cannot be connected by electric welding, gas welding, or exothermic welding. and other conventional connection means, which limits its promotion and use to a certain extent
