摘要
中性点加装消弧线圈是提高小电流接地配电系统可靠性的有效措施,对10 kV电网无阻尼调匝消弧线圈、有阻尼自动调匝消弧线圈、自动调容消弧线圈和相控消弧线圈4种类型的消弧线圈的灭弧效果进行测试分析,给出了每种消弧线圈灭弧能力的量化数据。
Installing the arc suppression coil at the neutral point is an effective measure to improve the reliability of the small current grounding distribution system. The arc extinction performance of four kinds of arc suppression coils for 10 kV grids is tested and analyzed, including the no-damping circle-adjusting arc suppression coil, the with-damping automatic circle-adjusting arc suppression coil, the automatic capacity-adjusting arc suppression coil, and the phase control arc suppression coil. The arc extinction performance of these arc suppression coils are evaluated quantitatively.
