Pole tower and transformer substation grounding calcium bentonite base resistance reducing agent

Abstract

The invention relates to a pole tower and transformer substation grounding calcium bentonite base resistance reducing agent. A recipe consists of the following ingredients in parts by mass: 1 to 99 percent of calcium bentonite, 1 to 30 percent of carbon fiber, 0.1 to 30 percent of ammonium chloride, 0.1 to 30 percent of calcium carbonate, 0.1 to 30 percent of zinc powder, 0.1 to 30 percent of copper powder, 0.1 to 60 percent of ammonium persulfate, 0.1 to 15 percent of sodium molybdate, 5 to 60 percent of electroconductive cement, 0.1 to 6 percent of graphene, 0.1 to 30 percent of aluminum powder, 0.1 to 60 percent of phenylamine and 0.1 to 15 percent of sodium tripolyphosphate. The resistance reducing agent belongs to a physical grounding resistance reducing agent, overcomes the defects of great packaging and construction difficulty and the like of the existing resistance reducing agent, solves the problem of strong corrosion performance of strong electrolyte, strong acid and strong base in the existing chemical resistance reducing agent, and solves the problem that a grounding body cannot normally work. The resistance reducing agent provided by the invention is applicable to acid soil areas, mountainous areas, rock areas, sand land and high-corrosion regions.

Description

technical field [0001] The invention relates to a calcium-based bentonite-based drag-reducing agent for grounding of towers and substations, belonging to the technical field of electric power grounding materials. Background technique [0002] Resistance reducing agent is an engineering material widely used in electrical grounding and lightning protection, especially in areas with high soil resistivity, it has a good resistance reducing effect. [0003] In areas such as sandy land and mountainous areas, the water retention of the soil is poor, resulting in high soil resistivity, which makes it difficult for the grounding resistance of the grounding system to meet the power industry standard. The commonly used methods to reduce the grounding resistance of the grounding system include increasing the cross-section of the grounding body and increasing the area of ​​the grounding grid. However, these methods greatly increase the amount of steel used, increase the cost, and have pr...

[0003] In areas such as sandy land and mountainous areas, the water retention of the soil is poor, resulting in high soil resistivity, which makes it difficult for the grounding resistance of the grounding system to meet the power industry standard

The commonly used methods to reduce the grounding resistance of the grounding system include increasing the cross-section of the grounding body and increasing the area of ​​the grounding grid. However, these methods greatly increase the amount of steel used, increase the cost, and have problems such as large construction volume and poor resistance reduction effect.
