Long-term anti-corrosion physical resistance reducing agent is a physical environmentally friendly resistance reducing agent. It is composed of polymer water-absorbing materials, electronic conductive materials,
ionic conductors and other materials. It is non-toxic, No odor, no corrosion, no pollution, in line with national quality soil environmental standards. Its electrical conductivity is not affected by changes in acid, alkali, salt, temperature, etc. It has good hygroscopic,
moisturizing and anti-freezing functions. It will not be lost due to the presence of groundwater and has a long-term improvement effect on soil resistivity.< br/> The ground net made by this product has stable grounding resistance and longer service life. br/> Main properties
. Good conductivity and resistance reduction. Long-term anti-corrosion physical resistance reduction agent has strong moisture absorption, Moisturizing properties, maintain a certain amount of moisture around the ground electrode, exert the conductive leakage effect of the electrolyte, and improve the conductivity of the surrounding soil, thereby increasing the structure size of the grounding body and increasing the resistance of the grounding body. The dispersion area reduces the grounding resistance.
.The corrosion-resistant and corrosion-inhibiting resistance reducing agent for metals is an intermediate medium between the metal grounding body and the natural soil. It can withstand the erosion of rainwater and groundwater and is non-corrosive. Moreover, it prevents gas, acid, alkali, salt and other corrosive media from corroding the ground metal material, and acts as a corrosion inhibitor for the ground body, thus ensuring the service life of the ground body.
. The stray current of the grounding device that can withstand the impact of large current is very small during normal operation, generally only
in the order of milliamps. However, when struck by lightning or a grounding short circuit occurs, there will be A large current flows through the grounding device. For lightning
the grounding current can reach tens of kiloamps. Under the impact of such a large current, the long-term anti-corrosion physical resistance reducing agent will not become hot,
spontaneously ignite or Forms volatile matter and has the ability to withstand repeated flow through and impact.
.Has certain negative resistance physical properties. The so-called negative resistance characteristics refer to the characteristic that its resistivity decreases as the scattering current density increases.
.Environmental protection: This resistance reducing agent is non-toxic and has no pollution to the environment. It is a paste and does not produce dust during transportation and construction.
It can significantly reduce environmental pollution and physical damage to operators. damage.
.Convenient construction. There is no need to add water and stir during construction. It can be wrapped directly around the grounding electrode. It is especially suitable for shortage areas such as wild mountains
. The construction is simple and can shorten the construction period.
Construction method
. Resistance reducing agent slurry preparation
After the ground body is laid and welded on site, the dryness and moisture level of the soil will be considered. The resistance reducing agent and water are usually in a (weight ratio). Stir evenly into a slurry in a bucket
cart or other container and use immediately.
.Grounding construction
, vertical grounding body
For shallow wells with general soil depth, a larger pit can be manually dug, and the mold can be placed after reaching the depth
(straight pipe or wooden pillars), gradually backfill with fine soil, tamp it layer by layer and gradually draft the mold
For deep wells or rocky hard soil, it must be formed with a drilling machine and then placed in the prepared grounded metal electrode for center grouting
Grouting When the deep well uses Ф (wall thickness) steel pipe for grounding, drill Ф
holes in order to prevent grouting.
.Horizontal grounding body
Dig a deep trench according to the designed length and orientation, place the grounding electrode in the small trench and weld it according to the design requirements, then use supports to conduct welding on different parts of the metal electrode
Support it in the material. According to the amount of resistance reducing agent per meter, pour the mixed slurry evenly into the trench to wrap the metal pole. After initial setting, backfill with fine soil and then compact the backfill soil layer.
Scope of application
Grounding devices for power plants, substations and transmission line towers.
Lightning protection grounding for missiles, rocket launchers, radars and other military facilities.
Lightning protection grounding for oil, natural gas, coal and other oil storage tanks.
, radio and television transmission towers, microwave towers and communication line grounding devices.
Protective grounding and working grounding of weak current equipment such as computers, laser imagesetters, etc.
In electrical grounding in industries such as chemical and textile, medicine and health, culture and education, publishing and printing.
, other grounding situations.
Construction dosage
Depending on the soil, the thickness of laying on the grounding body should be in the range. The recommended dosage is as follows
