文章介绍水电站接地电阻的计算方法以及高土壤电阻率环境下降低水电站接地电阻的措施,重点提出一种通过采用新型电解地极的降阻方法,该方法在多石、岩石、沙石等土壤电阻率较高的环境中,可以显著降低较传统降阻措施中因增加接地网面积或挖多个深井等措施而产生的较高施工成本,并通过青海江源水电站降阻实例分析验证文中提出方法的工程实用性和有效性。
This paper introduces the calculation method of grounding resistance of hydropower station and the measures to reduce the grounding resistance of hydropower station under the condition of high soil resistivity. The article puts forward a method of reducing resistance by using the new electrolytic pole. Higher rate of environment, can significantly reduce the higher construction costs caused by increasing the ground network area or digging a number of deep wells compared with the traditional resistance reduction measures, and through the Qinghai Jiangyuan Hydropower Station to reduce resistance example analysis method proposed in the paper The practicality and effectiveness of the project.
