摘要
消弧线圈的伏安特性直接影响单相高阻接地的补偿效果,开展消弧线圈现场伏安特性测试十分必要。介绍了采用变频电源作为试验电源在工程现场对10 kV干式消弧线圈进行伏安特性测试的研究和应用。通过分析10 kV干式消弧线圈的性能参数及试验过程,并且对整个试验回路进行了适应性计算,与试验实测数据进行了对比分析,得出了利用变频装置在现场开展消弧线圈伏安特性测试的可行性。
The volt-ampere characteristic of arc suppression coil directly impacts on the compensation effect of one-phase high resistanceground,it is very necessary to carry out the field volt-ampere characteristics test of arc suppression coils.Introduction was made to the researchand application that a variable-frequency power supply was adopted as a testing power supply at engineering site to carry out the volt-amperecharacteristic test for10kV dry-type arc suppression coil.After the performance parameters and testing process of10kV dry-type arc suppressioncoil analyzed and also took the adaptive computation for the whole test circuit,compared with the experimental results,this paper proposedthe feasibility scheme to use the variable-frequency device to carry out the arc suppression coil volt-ampere characteristic test.
