摘　　要：针对带极性选择器的有载分接开关,在配置不同阻值电位电阻的情况下开展有载分接开关的带电切换试验,通过分析试验现象和油色谱,评估了电位电阻阻值对有载分接开关极性选择器带电动作时的影响,对于有载分接开关电位电阻的适配性分析具有指导意义。For OLTC with reversing change-over selector, the energized operation test of OLTC is carried out under the condition of configuring tie-in resistors with different resistance values. By analyzing the test phenomenon and oil chromatogram, the influence of tie-in resistors resistance value on the energized operation of reversing change-over selector is evaluated. It can guide the adaptability analysis of OLTC tie-in resistors.
