A Zero- ohm grounding System

Abstract

The invention discloses a zero-ohm grounding system, comprises a plurality of graphite bodies connected end to end, wherein the graphite bodies are connected into a strip-shaped or planar reticulatedor stereoscopic reticulated grounding system, adjacent graphite bodies are connected through threads, the threaded connection structure comprises graphite studs and threaded holes, and the end parts of the graphite bodies are provided with threaded holes; The cross-sectional shapes of the graphite bodies include polygonal shapes, circular shapes and plum blossom shapes; The adjacent graphite bodies of the strip-shaped grounding system are connected through a graphite screw post matched with a threaded hole of an end part of the graphite body; The planar mesh and the three-dimensional mesh grounding system further comprises a turning angle connector of a steering connection, wherein the turning angle connector is provided with not less than two threaded holes, and the centerline of the threaded holes of the turning angle connector is at least provided with a pair of different directions; The invention has the advantages of light weight, low resistivity, excellent mechanical properties,good corrosion resistance, environmental protection and no pollution, long service life and wide application range.

Description

technical field [0001] The invention belongs to the technical field of electric grounding equipment, and in particular relates to a zero-ohm grounding system. Background technique [0002] Departments such as electric power, communication, and railway all lay metal materials in a large area or bury metal deeply when laying ground wires, in order to achieve its normal operation. The rapid development of modern electronic technology. In particular, precision instruments require very low grounding resistance, even close to zero resistance, but usually the soil quality is different, and the soil conductivity is also different. It is very difficult to achieve below 1Ω. Generally, chemical methods are used to change the conductivity of the soil to reduce the resistance of the soil. However, this method is complex and difficult to construct, and will cause environmental pollution. [0003] Another direct reason for the large ground resistance of the traditional ground wire device...
