Embodiment 1

[0031] A grounding module, which is composed of an external non-metallic conductive material wrapped with a built-in metal pole core. In terms of weight percentage, the external non-metallic conductive material consists of 15% artificial graphite powder, 50% natural phosphorus flake graphite and 35% high-grade Composed of conductive cement, the built-in metal grounding body is φ18 galvanized rebar.

[0032] The grounding module can be prepared by conventional preparation methods, for example, including the following steps:

[0033] (1) Ingredients: weighed according to the weight ratio, artificial graphite powder with a particle size of less than 0.5mm: 15%, natural phosphorus flake graphite with a mesh number of 50: 50%, 525# high-grade cement: 35%;

[0034] (2) Kneading: Put the artificial graphite powder, natural flake graphite and high-grade cement in the ingredients into the kneading pot, add a certain amount of water, and stir for 40 minutes to make it fully kneaded even...

Embodiment 2

[0038] A grounding module, which is composed of an external non-metallic conductive material wrapped with a built-in metal pole core. In terms of weight percentage, the external non-metallic conductive material consists of 10% artificial graphite powder, 60% natural phosphor flake graphite and 40% high-grade conductive Composed of cement, the built-in metal grounding body is φ18 galvanized rebar.

[0039] The grounding module can be prepared by conventional preparation methods, for example, including the following steps:

[0040] (1) Ingredients: weighed according to the weight ratio, artificial graphite powder with a particle size of less than 0.5mm: 10%, natural phosphorus flake graphite with a mesh size of 50: 60%, 525# high-grade cement: 40%;

[0041] (2) Kneading: Put the artificial graphite powder, natural flake graphite and high-grade cement in the ingredients into the kneading pot, add a certain amount of water, and stir for 40 minutes to make it fully kneaded evenly; ...

Embodiment 3

[0045] This embodiment also provides a grounding module with a specification of ￠150*800 as in Example 1. The difference is that the grounding module is prepared according to the preparation method described in the present invention. The specific preparation method includes the following steps:

[0046] (1) Ingredients: weighed according to weight ratio, artificial graphite powder with a particle size of less than 0.5mm: 15%, natural phosphorus flake graphite with a mesh size of 50: 50%, 525# high-grade cement: 35%.

[0047] (2) Kneading: Put the prepared artificial graphite powder and natural flake graphite into a kneading pot, add a certain amount of water, and stir for 25 minutes; then add high-grade cement in the ingredients and stir for 20 minutes to make it fully kneaded evenly.

[0048](3) Extrusion: use φ18 galvanized rebar as the metal pole core, put the kneaded raw materials into the mold, and vibrate for 5 minutes at a vibration frequency of 200HZ and an amplitude of...

Abstract

The invention discloses a grounding module and a preparation method thereof, belonging to the technical field of electric power and communication equipment. The grounding module includes a metal pole core and a non-metallic conductive material wrapping the metal pole core. Calculated by mass percentage, the non-metallic conductive material is composed of 10-15% artificial graphite powder, 45-60% natural Composed of phosphorus flake graphite and 30-40% high-grade cement, the grounding module is less affected by the seasons, and has the characteristics of convenient installation, corrosion resistance, and reliable performance. The present invention also provides a preparation method of the grounding module, including batching, kneading, extrusion, pressure maintaining, maintenance and other processes. The method is easy to operate and low in cost.

Description

technical field [0001] The invention relates to the technical field of electric power and communication equipment, in particular to a grounding module and a preparation method thereof. Background technique [0002] The power grounding system is an important facility to ensure the safe and reliable operation of power equipment. The grounding device is the general name of the grounding body and the grounding wire. Its function is to guide the lightning current into the ground, and the protection of the lightning protection system is largely related to this. The grounding body, also known as the grounding electrode, is a metal conductor or conductor group that is in direct contact with the soil, and is divided into an artificial grounding body and a natural grounding body. The grounding body acts as a conductor that is in close contact with the soil of the earth and provides an electrical connection with the earth, safely dissipating the lightning energy and causing it to leak...
