降低接地装置接地电阻的新方法

A New Method to Decrease Grounging Resistances of Grounding Systems

提出了一种在高土壤电阻率地区降低接地装置工频接地电阻的新方法，即深孔爆破制裂———压力灌降阻剂法；分析了这种方法的主要原理，即利用地下电阻率较低的土壤层、降低接触电阻和土壤的散流电阻。

How to decrease the grounding resistance of grounding system with high resistivity is a formidable project A new method to decrease grounding resistance, by explosion and making cracks in deep hole and filling decreasing-grounding-resistance-agent(DGRA)into the hole by pressure(EMCDH-FDHP) is proposed The principle of the new method is analyzed, which uses the soil layer with low resistivity, decreas contact resistance and the resistance of dispersing current, links the cracks of soil and forma passageway with low resistivity
