在接地工程中,计算机的静电接地要求接地电阻值R≤1Ω,要满足这样低的电阻值,在工程设计与施工中是比较困难的,为减小接地电阻,将会浪费大量的钢材并占用大面积土地。本文提出选择合适的人工置换土壤电阻率,供同行的参考。 1.降阻剂的选择 人工改善地电阻率有浸渍和置换两种方法。前者是采用低电阻率的化学溶液,用高压泵将溶液压入高电阻率的地层中,这种方法可以较大范围地减少地电
In the grounding project, the computer’s electrostatic grounding requirements grounding resistance R ≤ 1Ω, to meet such a low resistance in engineering design and construction is more difficult to reduce the grounding resistance, will waste a lot of steel and occupy Large area of land. This paper proposes to select the appropriate artificial soil replacement resistivity for peer reference. 1. Jiang Zuji choice Artificially improved resistivity impregnation and replacement of two methods. The former is the use of low-resistivity chemical solution, using high-pressure pump solution into the high resistivity of the formation, this method can be a greater reduction in power
