摘要
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。
The problem of lightning progressive wave protection for electrified railway traction substation of our country has been studied in this paper. Eight different methods of lightning-protection for traction substation have been analysed and compared with on their reliability. The protection reliability of the zinc-oxide arrester and that of the type FZ-35 valve attester have been calculated respectively, When any one of the two devices is adopted in substation. The impact on reliability of lightning-protection has been analysed for these three cases; Lightning-resistant coil erected in circuit exit, Layout of arrester, and characteristics of arrester. Rational protection measures are to be recommended. The results may be used for lightning-protection in designing traction substation.
