摘要
对单母线分段接线、多电源系统、常见TN系统电源中性点接地方式接线做法进行分析和比较,提出能满足规范和功能要求的两种接线方式。对常见的一点接地的接线做法进行调整和优化,对两种接地方式接线做法的适用范围进行阐述。
The wiring practices of power neutral-point grounding modes for the sectionalized single-bus connection,the multi-power supply system and the power supply to common TN system are analyzed and compared to put forward two wiring modes that can meet the code and functions requirements.The common one-point grounding wiring practices are adjusted and optimized,and the scope of application of the two grounding wiring practices are elaborated.
