Problems solved by technology

However, most of these metal materials have poor corrosion resistance, short service life and high maintenance costs, except for the higher-priced copper grounding materials.
And in the process of use, it often faces difficulties in transportation and construction. Due to the inconvenience of bending, it is difficult to choose the construction method according to the terrain.
In addition, due to the high value of secondary use of metal materials, accidents of metal grounding bodies being stolen and destroyed by humans emerge in endlessly, which brings serious hidden dangers to the power system.

Embodiment 1

[0023] A kind of manufacture technology that is conducive to the flexible graphite grounding body of electric conduction, comprises the following steps:

[0024] S1. Choose graphite with a carbon content ≥ 99%. After washing with water, washing with concentrated sulfuric acid, and drying, expand it at a temperature of 700-1200°C to become a graphite worm whose volume is more than 200 times its own volume. After expansion, the appearance of graphite is fluffy Pile of powder, worm-like under the microscope;

[0025] S2. Using alkali-resistant glass fiber as the skeleton, adding graphite worms and acrylic pressure-sensitive adhesive emulsion, wherein the weight ratio of alkali-resistant glass fiber, graphite worms, and adhesive is 15:75:10. Shaped under 5 tons of pressure, made into a cloth with a width of 450-550mm;

[0026] S3, the cloth made in step S2 is divided into strips, and twisted into thin graphite threads;

[0027] S4. Twisting a plurality of thin graphite wires int...

Abstract

The invention relates to a flexible graphite grounding body beneficial for conduction. The flexible graphite grounding body comprises an inner-layer graphite harness and a graphite line weaving layer,wherein the inner-layer graphite hardness comprises graphite lines arranged in parallel, and the outer-layer graphite line weaving layer is obtained by weaving the graphite lines. The flexible graphite grounding body has the advantages of corrosion resistance, no rust, no large-current impact, high- and low-temperature resistance, stable grounding resistance, maintenance free, updating free, safety and reliability and is suitably used in acid land, alkali land, wetland, hot wet place, sea salt and mountains and hills which are difficult to construct and is relatively high in soil resistivity.

Description

technical field [0001] The invention belongs to the technical field of lightning protection and grounding, in particular to a graphite grounding body. Background technique [0002] With the continuous development of the power grid, the construction of transmission lines has increased accordingly. In order to ensure the safe and stable operation of the lines, the requirements for the grounding grid have also increased. Lightning strikes on power lines mostly occur in areas with frequent lightning activities and high soil resistivity, which brings huge safety hazards and economic losses to the power system. [0003] At present, my country's lightning protection grounding body is divided into two types: metal and non-metal. The mainstream lightning protection grounding body in the market is a metal grounding body, and the materials used include carbon steel, galvanized steel, stainless steel, copper and other metal materials. However, most of these metal materials have poor c...
