摘要
特高压线路因具有很高的耐雷水平而几乎不存在因雷击杆塔或地线而发生反击,本文根据特高压杆塔比较高的特点,提出了特高压架空线路大多遭受小雷电流侧击(或绕击)主要起因于雷电分岔先导的观点,进一步探讨了特高压线路架设多根地线的必要性和可行性,以及多根地线对造价的影响,并对特高压直线塔电气模型进行了优化设计。
Because of higher withstand lightning level, back strike does not hardly happen on the UHV AC lines, according to higher characteristic of UHV tower, we put forward a view that UHV lines being suffered by little lightning current's lateral strike(or shielding failure),is mainly because of lightning bifurcate channel, and inquire into further necessity and feasibility of erecting more lightning wires on the UHV line and more lightning wire's effect on cost of project, and make optimum design for the HUV straight line tower's electrical model.
