本文对我国电气化铁道牵引变电所的雷电进行波保护问题进行了研究。对八种不同的牵引变电所防雷保护方式进行了可靠性分析和比较;并分别计算了变电所内采用氧化锌避雷器和FZ-35型避雷器保护时变电所的可靠性;分析了线路出口处安装抗雷圈,避雷器布置和避雷器特性对变电所防雷可靠性的影响。推荐了合理的保护方式。所得结果,可供设计牵引变电所防雷保护使用。
This paper studies the wave protection of thunder and lightning in China’s electrified railway traction substation. Reliability analysis and comparison of lightning protection methods for eight different traction substations were carried out. Reliability of substations using ZnO surge arresters and FZ-35 surge arresters in substations was calculated respectively. Impact of lightning arrester installed at exit, arrester arrangement and arrester characteristics of transformer substation lightning protection reliability. Recommended a reasonable protection. The results, for the design of lightning protection transformer substation use.
