摘　　要：对目前国内 5 0 0、2 2 0 k V变电所 2 2 0 k V侧电压互感器常规配置方案及存在问题进行了分析总结 ,提出一种新的电压互感器分散配置方案。以 5 0 0 k V潜江变电所为例 ,经过分析比较 ,确定 2 2 0 k V电压互感器选用进出线配三相电压互感器。A new distributed allocation scheme of voltage transfo rm er is submitted, through which normal schemes are analyzed for 220 kV voltage tr a nsformer of 500,220 kV substations. For the example of 500 kV Qianjiang Substati on, it is submitted that three phase voltage transformer is allocated on incomi ng/outgoing line and single phase voltage transformer is allocated on bus throu gh comparison and analysis.
