Insulation and Lightning Protection Performance Analysis of a Solid-sealed Lightning Protection Bushing for Distribution Transformer

本文提出一种配电变压器用固封绝缘防雷套管用于深度限制雷电过电压,分析并得出结论,此防雷套管实现了配电变压器的出线引出和防雷功能一体化,可通过有限元法提高其参数设计的针对性与准确性。

This paper proposes a solid-sealed insulation lightning protection bushing for distribution transformers to limit the lightning overvoltage in depth. The bushing realizes the integration of the output lead-out and lightning protection function of the distribution transformer, and can improve the pertinence and accuracy of its parameter design through the finite element method.
