利用工业建筑物的钢和钢筋混凝土结构作为接地装置[文献1],是基于下列三点先决条件的:1.被金属结构彼此连接起来的钢筋混凝土基础网的流散电阻,可像具有同样面积闭合接地网的流散电阻那样进行计算。2.工业建筑物的金属结构,在满足一定
The use of steel and reinforced concrete structures of industrial buildings as grounding devices [Literature 1] is based on the following three preconditions: 1. The distribution resistance of reinforced concrete foundation nets connected to each other by metallic structures can be closed as if they had the same area. The dispersion resistance of the ground grid is calculated as described above. 2. The metal structure of industrial buildings meets certain requirements
