The grounding rod is a kind of grounding pole. It generally refers to a metal body that is vertically driven into the ground. It can be round steel or angle steel. Such grounding poles are generally connected by flat steel to form a grounding grid. The grounding grid can also be directly used horizontally laid flat steel or flat steel mesh, they are also grounding poles, but not called grounding rods.
Through the ion release effect of the internal and external filling materials of the electrodes, the contact environment between the electrodes and the surrounding soil is improved, and the purpose of reducing the resistance is achieved. The resistance in a certain area is lowered grounding rod by laying a large amount of metal materials, and the common grounding method is implemented to achieve low grounding resistance and electrolysis. The ion grounding electrode adds a reversible slow release filler to the ground electrode. This filler has the characteristics of water absorption, water release and reversibility. When it absorbs water, it can absorb 100-500 times of its own water. When the external environment is dry and dehydrated, it can completely release the water it owns and reach the surrounding water balance. This reversible reaction effectively ensures the effective environment inside the shell. Humidity ensures the stability of the grounding resistance. After the ions generated in this way absorb the moisture of the earth, the active electrolytic ions can be activated by deliquescence.
Effectively released into the surrounding soil, making the grounding electrode an ion generating device, thereby improving the surrounding soil quality and meeting the grounding requirements. The grounding electrode external filler generates chemical treatment for the shell soil through interaction with its internal electrolytic ion filler, reduces the resistivity of the shell soil, and forms a transition zone between the slow-release grounding electrode and the earth soil. The equivalent cross-sectional area of the grounding electrode and the contact area of the soil are increased, the contact resistance between the grounding body and the soil is eliminated, the electric field distribution in the ground is improved, the permeability of the filler is good, and the depth is penetrated into the soil and the rock seam. Forming a tree root network, increasing the drainage area in the ground.
