摘要
对山区、重雷区配电网雷击损坏的事故进行了认真的调查、分析,特别分析了山区农村电网的雷电活动、雷击变压器的损坏、配电网和配电变压器的防雷保护,如避雷器的选型、安装以及变压器的接地引下线和接地装置的状况.针对山区重雷区配电变压器在防雷保护上存在的问题和不足,提出了综合的防雷保护方案.
The lighting accidents in mountainous areas and lightning occurences in power grid in countryside are investigated, and the damage of transformer by lightning and the lightning protection of distribution transformer are analyzed in this paper, in the aspects of the model selection and and tecti grounding device of distribution transformer. After analyzing the on of distribution transformer, some integrated schemes of them installment of arrester, the grounding wire problems existing in present lightning protection of distribution transformer, some integrated schemes of them are proposed.
