摘　　要：为了解决基站专用变压器损坏的问题,运用"瞬态等电位"防雷理念,研究探讨了雷电对基站专用变压器的损害机理,在对高压线、低压线、地电位反击和直击雷这四个雷害主要引入渠道进行分析的基础上,采用了合理配置避雷器、正确选取零参考点、有效连接各部分设备等关键技术,解决了雷击损坏变压器的难题。实践结果证明,"瞬态等电位"技术可以有效地保护变压器,按照标准改造的变压器未再出现损坏。To solve the base station specialized transformer damage problem, using ＂transient equal potential＂ lightning protection theory, the mechanism of lightning damage on the base station’s special transformer was discussed, based on the analysis of four main lightning introducing channel, including high-voltage line, low-voltage line, ground potential counterattack, and direct lightning attack, key technologies were employed to solve the problem of lightning damage of transformer, such as rational configuration of lightning arrester, correct selection of zero reference point, and effective connectivity of each part of the transformer. It was proved by actual results that ＂transient equal potential＂ lightning protective technology can effectively protect the transformer, with no damaged record in the altered transformers.
