摘要
通过对井上660 V供电系统变压器中性点各种运行方式分析比较,得出其中性点不接地运作方式,较中性点经高阻接地、消弧线圈接地及直接接地运行方式更安全、可靠的结论。
By comparison the various operation modes of ground 660 V power supply system transformer neutral point,drawing a conclusion that the ungrounded operation mode of neutral point is more safe and reliable than high resistance ground,circle around the grounding or direct ground mode.
