消弧選線方案的實際應用

摘要：接地變壓器或發電機的中性點上，消弧線圈并聯中電阻選線法是采用接地時在消弧線圈兩端瞬間投切并聯電阻的方法，瞬間向接地點注入電流有功分量，使接地點的電流幅值和相位都有很明顯的變化，接地選線的準確性可達到100%。 敘詞：中性點 消弧線圈 電阻 接地 選線 Abstract：On neutral point of grounding transformer or generator, resistor line selection through arc-suppression coil patroller alignment program is when ground connecting switching to parallel resistor, which means switching to the injection location current active component so that the current amplitude and phase change noticable. The accuracy of line selection when ground connecting can be 100%. Keyword：neutral point, arc-suppression coil, resistance, grounding, alignment
