| 摘 要： | 在变压器中性点不接地、变压器中性点直接接地、消弧线圈接地三种方式下,对人身触电、单相接地情况下的电流进行了计算和比较,得出变压器中性点经阻抗接地方式是比较可取的,它与电网电容自动补偿,可减小单相接地电流。

| Abstract: | In three circumstances of transformer neutral-point unearthing,transformer neutral-point direct grounding and extinction coil grounding,the author calculates and compares the electric current under the conditions of personal electric shock and single-phase grounding,and draws a conclusion that the grounding mode of transformer neutral-point by impedance is advisable which can automatic compensation with electric network capacitance and can reduce single-phase grounding electric current. |

| Keywords: | transformer neutral-point grounding mode singlephase grounding |
