摘要:通过调研湖南、广西、河南等省的农网10kV配电变压器的运行情况,结合分析其配电变压器在防雷保护方面的现状,指出了目前的问题主要存在于接地装置和低压侧避雷器装设等方面,用理论计算和仿真分析的方法对存在的问题进行了研究,认为严格限制配变台区接地装置的接地电阻,并做好防腐处理;配电变压器高、低压侧装设避雷器保护;加强对雷电活动强烈的配变台区的巡视检查是切实有效、可行的方案,建议供电部门实施。

Abstract: By investigating and reseaching the running situation of 10kV distribution transformer in rural power grid in Hunan,Guangxi and Henan province , analysising the current situation of distribution transformer lightning protecting measures , then pointing that the main problems lies in grounding device and the setting of arrester in low voltage side, studying these problems by theoretical calculation and simulation analysis .The paper believing that strictly restricting the grounding resistance of distribution tansformer divice, doing well in the anti-corrosion measure , setting arresters both in high voltage side and low voltage side and inhancing the periodical perambulation and inspection in the place where lightning action is frequent are the valid and feasible scheme, suggesting the power supply department adopting .
