摘要:
由于10~35 kV配电线路的绝缘水平普遍较低,因此在我国配电线路雷电保护设计中经常采用氧化锌避雷器进行雷电防护。通过建立模型开展数值仿真计算,进行10 kV配电线路安装线路避雷器的雷电防护效果研究,分析不同避雷器类型、不同杆塔冲击接地电阻以及雷击位置等对避雷器防护效果的影响并并分析其保护范围。结果表明,加强线路绝缘、增加配电线路中的避雷器数量可显著提高整条配电线路的耐雷水平,是提高配电线路防雷效果的两个重要措施; 雷击位置对线路耐雷水平的影响则与避雷器雷电保护范围密切相关,当雷击位置距离线路避雷器较远时,线路耐雷水平的下降较为明显; 具有避雷器的配电线路,由于避雷器存在一定的保护距离,因此单纯依靠安装线路避雷器来提高耐雷水平则需要每隔6~8基杆塔安装一组避雷器。
Abstract:
Considering that the insulation level of 10~35 kV distribution lines is generally low, zinc oxide arrester is often used for lightning protection of distribution lines in China. The lightning protection effect of lightning arrester installed on 10 kV distribution line is studied by establishing a model to carry out numerical simulation calculation. The influence of different types of arrester, different tower impulse grounding resistance and lightning strike location on the protection effect of lightning arrester are analyzed and its protection range is also discussed. The results show that strengthening line insulation and increasing the number of arresters in distribution lines can significantly improve the lightning protection level of the whole distribution line, which are two important measures to improve the lightning protection of distribution lines. The influence of lightning strike location on the lightning protection level of lines is closely related to the lightning protection range of arresters, when the lightning strike location is far from the line arrester, lightning withstand level of the line decreases obviously. For the distribution line with the arrester, because the arrester has a certain protection distance, it is necessary to install a group of arresters every 6-8 towers to improve the lightning withstand level.
