Overview and performance of electrolytic ion ground electrode

29-04-2020

The electrolytic ion grounding electrode tube is filled with high-carbon ion compound crystals, and the surface is made of copper-plated steel composite material, pure copper, and stainless steel. To ensure the best conductive performance and long service life. The filler material inside the conductor contains a special electrolytic ion compound, which can fully absorb the moisture in the air. Through deliquescence, the active electrolytic ions are effectively released into the soil, combined with the moisture in the soil and the air, which further promotes the slow release of the conductor and reduces the resistance, and keeps the resistance value stable for a long time.

 

The compound inside the conductor gradually becomes a transparent state of colloid with time. We use the conductive properties of the colloidal compound to make the entire system in the state of ion exchange for a long time, thus forming an ideal electrolytic ion ground electrode. Working principle: The electrolytic ion ground electrode is added with reversible slow-release filler in the ground electrode. This filler has the characteristics of absorbing water, releasing water, and reversible. When it absorbs water, it can absorb 100-500 times its own moisture. When the external environment is dry and lacks water, it can completely release its own moisture and achieve the surrounding moisture balance. This reversible reaction effectively guarantees the effectiveness of the internal environment of the shell. Humidity ensures the stability of the grounding resistance.

After the ions generated in this way absorb the ground water, the active electrolytic ions can be effectively released into the surrounding soil through deliquescence, making the ground electrode an ion generating device, thereby improving the surrounding soil quality to meet the grounding requirements. The external filler of the ground electrode generates a chemical treatment for the shell soil through the interaction with the internal electrolytic ion filler, which reduces the resistivity of the shell soil. At the same time, a transition zone is formed between the slow-release ground electrode and the ground soil. The equivalent cross-sectional area of ​​the ground electrode and the contact area of ​​the soil are increased, the contact resistance between the ground body and the soil is eliminated, the electric field distribution in the ground is improved, and the good permeability of the filler penetrates deep into the soil and rock cracks , Forming a root network, increasing the drainage area in the ground.

 

Construction method:
1. Drilling: Drill the diameter at the selected construction site
Holes of 160mm × 150mm × 1550mm vertical ground.
2. Configure the filler: mix the filler with water to make a paste (a little thick and fluid) and pour it into the hole drilled in advance, the depth is about the hole position;
3. Implanting the ground electrode: a Remove the sealing tape of the ground electrode; b implant the ground electrode in the hole, the top of the ground electrode is flush with the ground; c connect the leads; d fill the remaining filler around the ground electrode to the ground electrode When the top is 100mm, measure the grounding resistance. After reaching the grounding resistance requirement, fill the electrode with soil.
Note: When one set of grounding electrode can not meet the resistance requirements, two or more sets can be used in parallel. The spacing between the rods should not be less than 5m. The lead wire adopts 50mm2 multi-strand copper wire. The lead wire and the ground electrode are pressed. Then, the node anti-corrosion treatment.
