摘要
本文通过对多电源10/0.4kV变电所系统接地实施的两种做法——变压器中性点直接就地接地法及一点接地法进行比较,说明一点接地法在防范杂散电流方面明显优于变压器中性点直接就地接地法,并列举实施一点接地法应注意的问题。
Through making comparison of two working methods for muhi-power system grounding in 10/ 0.4kV substations： transformer neutral point direct earthing and onepoint earthing, this paper points out that one-point earthing method is better than transformer neutral point direct earthing in the aspect of preventing stray current, and highlights the issues that should be concerned if implementing one-point earthing method.
