摘要
本文说明了实际工程中正确理解接地符号的内含,有助于对“接地”效果的分析;简述了在工程设计中根据接地电阻值的要求,估算接地体数量;分析了“一点接地”和“等电位”的概念。
The paper points out that to understand the meaning of grounding correctly will be of assistance to analyze the efficiency of grounding according to the engineering project. It expounds that according to the requirements of grounding resistive value, the numbers of grounding pole will be estimated, and analyzes the concept of "one-point grounding" and "equipotential" as well.
