摘 要：分析了杭州地區(qū)110 ～ 500 kV 輸電線路雷擊跳閘原因，并根據(jù)該地區(qū)雷電活動(dòng)的特點(diǎn)制定了相應(yīng)的防雷改造對策，通過采用“改造接地電阻為主，加裝避雷器為輔”的防雷措施，大幅度提高桿塔的反擊耐雷水平，有效防止線路繞擊，降低了線路雷擊跳閘率。

Abstract: Analysis was made to 11 0~500 kV transmission line lightning tripping causes in Hangzhou area and according to the features of the area lightning activities, this paper laid down the corresponding anti-lightning reform countermeasures. Via adoption of anti-lightning measures as reforming grounding resistance as the main; additionally installing arrestors as the assistance, the anti-lighting level of pole tower was greatly lifted, which effectively prevents lines from winding lighting, reducing line lighting tripping rate.
        Key words: transmission line; lightning; cause; countermeasure
