摘　　要：雷电波侵入是牵引变电所主要的雷害方式,牵引变电所馈线侧抗雷线圈与避雷器的组合方式不同,对馈线侧设备雷电过电压的影响不同。拟通过仿真分析,探明抗雷线圈安装方式及参数对变电所馈线侧雷电过电压的影响规律,明确抗雷线圈的防护效果,对设计提出建议。首先,通过电磁暂态仿真软件建立变电所馈线侧模型,分馈线侧架设抗雷线圈和不架设抗雷线圈两种情况进行研究;仿真得到雷电侵入变电所时,两种情况下变电所设备的过电压波形;通过比较分析过电压波形的差异,得到不同情况下抗雷线圈的防雷效果。The invasion of lightning is the main lightning damage to the traction substation. Different combinations of lightning-proof reactor and arrester may pose different effects on lightning over-voltage of feeder side equipment. This paper tries to find out the effects of the installation methods and parameters of lightning-proof reactor on lightning over-voltage of feeder side equipment, to define the protection effects of lightning-proof reactor, and to put forward recommendations on the design. First, circuit models for substation feeder side are established with electro-magnetic transient simulation software to analyze the differences with lightning-proof reactor and without on feeder side. Then, over-voltage waveforms on equipment are obtained with simulation for the two circumstances. At last, lightning protection effects of lightning-proof reactor in different cases are obtained through analysis of the difference in over-voltage waveforms.
