摘　　要：文章通过对乌鲁木齐城区重雷区配电网雷击损坏的事故进行全面的调查和分析,造成配电变压器雷害事故的主要原因为低压侧未安装避雷器、配电线路防雷保护存在问题以及变压器接地引下线接地方式存在问题。针对上述配电变压器在防雷措施上存在的问题,提出了加强完善配电网避雷器保护、改善配电网杆塔和变压器台区的防雷接地以及加装自动跟踪补偿消弧装置的综合防雷保护措施,为后期配电变压器防雷保护提供参考。Based on the investigation and analysis of the lightning damage accident of the distribution network in the heavy mined area of Urumqi City, the main causes of lightning accidents of distribution transformers are the lack of arresters installed on the low voltage side, the problems of lightning protection of distribution lines, and the problems of grounding mode of transformer grounding leads. Aiming at the problems existing in the lightning protection measures of the distribution transformer, this paper puts forward the comprehensive lightning protection measures of strengthening and perfecting the protection of lightning arresters in distribution network, improving the lightning protection and earthing of distribution network towers and transformer station areas, and installing the automatic tracking compensation arc suppression device, so as to provide reference for lightning protection of distribution transformer in the future.
