摘要
简述配电系统及电路接地的基本概念,接地符号的内涵,一点接地、等电位及等电位联结的概念。列出对应各类接地体型式的"接地体数量速算表",并用表格方式列出了各种接地系统型式的定义、特点及应用场所。
The basics of distribution system and circuit grounding, the meaning of grounding symbol and the concepts of one-point grounding, equipotential and equipotential bonding are described. A “Rapid Calculation Table for the Number of Grounding Body”which corresponds to various types of grounding bodies is established. The definitions, characteristics and application places of various types of grounding systems are listed in table format.
