例如增加绝缘子串的片数、改用大爬距悬式绝缘子、增大塔头空气间距等,这样

For example, increasing the number of insulator strings, switching to suspension insulators with large climbing distances, increasing the air spacing of the tower head, etc., of course, can also improve the lightning resistance level of the line and reduce the arc construction rate, but there will be considerable limitations in implementation. . Generally, in order to improve the lightning level of the line, the method of reducing the grounding resistance of the tower is given priority.

For example, to increase the number of insulators string, to use large climbing distance suspension insulators, increase the air spacing of the tower head, etc. , this can certainly improve the line lightning resistance level, reduce the arcing rate, but the implementation will have considerable limitations. Generally in order to improve the level of lightning on the line. Priority is given to reducing the ground resistance of the rod tower.

For example, increasing the number of insulator strings, using large climbing distance suspension insulators and increasing the air spacing at the tower head can also improve the lightning withstand level of the line and reduce the arc building rate, but the implementation will have considerable limitations. Generally, in order to improve the lightning level of transmission line, the method of reducing tower grounding resistance is preferred.<br>
