摘　　要：从供电低压侧发生接地故障、10 kV电源端中性点不接地、小电阻接地以及10 kV负荷侧发生接地故障等方面,结合TN/TT系统分析上述接地故障时对路灯安全危害,论证路灯设置辅助等电位联结的必要性。This paper considers the TN/TT system when analyzing the safety hazards to streetlights in the following cases:ground faults occur on the low voltage side of the power supply;and ground faults occur on the 10 kV load side,when the neutral point of the 10 kV power supply is not grounded or when small resistance is grounded.It shows that it is necessary to install auxiliary equipotential bonding on outdoor streetlights.

关 键 词：等电位联结 中性点不接地 小电阻接地 TN/TT系统 接地故障
