经过对玉林电视台塔楼遭受强雷击损害,避雷针保护与针(网)混合保护比对,引下线根数对分流系数影响,变压器设置在建筑物内外对雷击风险值影响的分析,得出电视台塔楼应采取针(网)混合保护、增加防雷引下线根数和变压器设置在建筑物内部等防护改造措施。
經過對玉林電視檯塔樓遭受彊雷擊損害,避雷針保護與針(網)混閤保護比對,引下線根數對分流繫數影響,變壓器設置在建築物內外對雷擊風險值影響的分析,得齣電視檯塔樓應採取針(網)混閤保護、增加防雷引下線根數和變壓器設置在建築物內部等防護改造措施。

Basing the strong lightning damage of Yulin Television Tower, comparing lightning protection with pin (net) mixed protection, the influence of down-lead root number on diversion coefficient, and the lightning risk of the impact value of transformer setting outside and inside the building were analyzed. The results show that such protective measures as taking pin (net) mixed protections, increasing the number of Lightning deflectors and transformers inside the building should be taken.
