【摘要】 架空送电线路雷击故障是影响安全供电的严重问题 ,长期以来 ,采用“堵塞”型思想的防雷保护措施 ,为此 ,综合评价高压架空线路“堵塞”型思想的防雷保护措施。随着变电站开关性能的提高和电网结构的完善 ,线路采用“疏导”型思想的间隙防雷保护是可行的 ,为此 ,探讨间隙防雷保护的设想、预期目标和研制工作 ,最后提出将“堵塞”、“疏导”型两种思想的防雷保护措施结合起来应用 ,可以把送电线路的防雷保护工作做得更好更多还原

【Abstract】 Lightning failures on overhead power transmission lines have serious impact on the safety of power supply. In this paper, the long used "block" type lightning protection scheme for HV overhead lines is comprehensively evaluated.With the improvement of substation switching performance and power network configuration, it is feasible to adopt "scatter" type gap lightning protection scheme. The conception, objective, research and development of the gap lightning protection are addressed, and the combination of the two schemes suggested to enable better lightning protection for power transmission lines.更多还原
