Analysis of Lightning Protection and Grounding Techniques for 220?kV High-voltage Transmission Lines in the New Era
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.
