摘要:

10 kV配电线路绝缘水平低,易受直击雷和感应雷的危害,雷击是造成配网事故的重要原因之一。为了减少雷害事故的发生,提高配电网的供电可靠性,开展配电线路雷电感应过电压模拟实验及真型实验研究可以获得真实雷电数据,并且为雷电过电压仿真计算提供依据,因此具有重要的工程意义和实用价值。本文首先介绍了雷电感应过电压模拟实验的基本思路,然后根据相应的实验目的合理设计了实验方案,最后将模拟实验结果与仿真计算结果进行了对比分析,从而证实了模拟实验的有效性。

The insulation level of 10 kV power distribution line is low, which is vulnerable to the direct lightning and induction lightning. Lightning is one of the important reasons for the accident of distribution network. In order to reduce lightning accidents and improve the power supply reliability of distribution network, it’s important in theoretic and engineering to run the simulation and real-model experiment of induction lightning overvoltage on the distribution line, which is able to get real lightning data to provide a basis for the simulation of lightning overvoltage. In this paper, the basic idea of the simulation experiment is introduced first. Then, a rational experiment plan is designed according to our aim. Finally, the result of our experiment and simulation is compared, which can confirm the validity of the experiment.
