摘要
我国在高压电力传输领域,220 kV的电路普遍遍布各处,通常这些电路是通过室外的悬空方式互联的,极易受到自然环境的干扰而导致故障,雷电对高压输电线正常运作破坏作用显著.遭遇极端凶猛天象所引发的电闪雷鸣对提供电源的系统可能产生负面影响,可以毁坏完整的220 kV高压传输线.因此,研究 220 kV高压传输线的避雷措施,并提升避雷接地技术的作用与效率,以期在最大程度上完善该高压线路的避雷接地系统,确保供电网的安全可靠运作.
Abstract
In China's high-voltage power transmission sector,220 kV circuits are widely distributed,often interconnected through outdoor suspension methods,which are prone to failures due to interference from the natural environment.Lightning strikes have a significant impact on the normal operation of high-voltage transmission lines.Extreme weather conditions that trigger lightning strikes can negatively impact the power supply system,potentially destroying intact 220 kV high-voltage transmission lines.Therefore,the research on lightning protection measures for 220 kV high-voltage transmission lines and the improvement of the effectiveness and efficiency of lightning protection grounding technology are aimed at optimizing the lightning protection grounding system of this high-voltage line to the greatest extent,ensuring the safe and reliable operation of the power supply network.
