摘要
从分流的角度,结合规程算法,分析了线路型避雷器对输电线路防反击及绕击的效果,构建了安装线路避雷器后的三相输电线路等效模型,并利用二分法和计算机编程,在考虑避雷器残压影响的情况下,推导出线路反击和绕击的分流系数以及工程计算线路耐雷水平的简化公式。
In order to analyze the effect of transmission line arrester against the shielding failure and the counterattack,this article from the point of view of the shunt resistance,combined with the regular method,the three-phase line arrester installation of transmission line equivalent model was establish,and used the dichotomy and computer programming,considering the influence of the arrester residual voltage,the shunt resistance of shielding failure and the counterattack and simplified formula to calculate lightning withstand level were derived.
