500 kV线路进线段高绝缘对变电站雷电侵入波防护的影响

摘要

The balanced high insulation design is used in 500 kV double circuit lines on the same tower. If the insulation is increased in 500 kV substation incoming line section, its influence to the substation insulation has to be analyzed based on reverse and circle lightning intrusive wave. The result shows that there are not any influence and damage to the substation equipment .%针对目前500 kV同塔双回线路普遍采用平衡高绝缘设计现状，从反击雷电侵入波和绕击雷电侵入波两个方面分析了500 kV进线段提高绝缘后对变电站绝缘的影响，研究表明：线路提高绝缘对反击雷电流和最大绕击雷电流的幅值没有影响，不会给站内设备带来额外的损害。
