摘要 IEC 60364标准中只有辅助等电位联结,而在GB 50054-2011《低压配电设计规范》中出现了局部等电位联结,针对此问题说明局部等电位联结的由来,比较辅助等电位联结、局部等电位联结两种做法的优缺点,并对新版IEC标准中辅助等电位联结内容及做法的改进进行说明。 The SEB only is referred in IEC 60364, while the LEB in the Code for Design of Low Voltage Electrical Installations （ GB 50054-2011）. This paper explains origin of LEB, compares advantages and disadvantages of SEB and LEB, and describes the improvement in contents and practices of SEB in new IEC standard.
