摘要
分析了影响输电线路耐雷水平的各种因素,包括:架空地线、杆塔的接地电阻、避雷器、耦合地线及线路的绝缘配合等因素,探讨了这些因素影响线路耐雷水平的机理,从而可以有针对性地选择防雷方法,来提高线路的耐雷水平,降低线路的雷击跳闸率。
The various factors affecting the lightning withstanding level of overhead power transmission lines(OHPTL): overhead grounding wire, tower's grounding resistance, lightning arresters, coupling ground wire, and insulation coordination are introduced and analyzed. Further approach to their mechanism is made in order to select the measures of lightning prevention directionally, and enhance the level of lightning withstanding more effectively and reduce the rate of lightning stroke.
