摘要：
In order to evaluate the protective effect of sideward lightning rod installed on the tower crossarm of UHVAC transmission line, its protective distance is calculated for three typical UHVAC towers in different conditions, which shows that, for better effect of shielding failure protection, the length of sideward rod installed on ZBS2 tower should be 6 m or more; in the conditions that the ground inclination angle is 0° and the wind deflection angle is less than 25°, the length of sideward rod installed on ZMP2 tower could be 4 m~5 m; if installed in the middle-phase crossarm of drum-shape tower, it could also be 4 m~5 m in the same conditions. © 2016, Electric Power Automation Equipment Press.
