摘　　要：通过分析调匝式消弧线圈运行中任意两档之间的级差电压变化特征,对采用残流增量法接地故障选线原理的可行性进行分析论证。首先在低压模拟环境中对比理论计算和实际测试数据,验证采用理论方法计算级差电压的可行性,最后以实际工程应用为例,分析其级差电压变化情况,为该方法实际应用提供理论和实践依据。This paper studies the feasibility of residual current increment for fault line detecting by analyzing the differential voltage between two stalls of multi-tap arc-suppression coil. Firstly, the differential voltages in the low voltage simulation model of theoretical calculating and from the practical measuring are compared to verify the feasibility of theoretical arithmetic for differential voltage calculation. Then, taking an actual engineering as an example, the change of differential voltage is analyzed, which provides a theoretical and practical basis for practical application of residual current increment.
