| 摘 要： | 我国城市轨道交通架空接触网导线离地高度和线路绝缘水平与电力系统10 kV配电线路相当,雷电防护应以防感应雷为主.本文对接触网感应过电压进行了仿真研究,利用统计方法计算了接触网感应雷击跳闸率,提出了采用避雷线、绝缘子保护间隙和串联间隙金属氧化物避雷器3种雷电防护措施. |
| 关 键 词： | 城市轨道交通 架空接触网 雷电防护 避雷线 绝缘子保护间隙 串联间隙金属氧化物避雷器 |

| Abstract: | The height of the contact line and the insulation level of the overhead contact system of urban mass transit(UMT) is equivalent to the 10 kV distribution grids of power systems.Therefore,the induced over-voltage protection should dominate the lightning protection for the system.The induced over-voltage is studied by using simulation method for the contact networks,and the lightning trip-out rate is given statistically in this paper.Furthermore,the paper provides three protection measures such as lightning s... |
