查询词典 choke coil

Simple external LF coil and tuning capacitor.

简化外部LF线圈和调谐电容。。。

With analysis on the control model, an improved automatic tuning method for arc-suppression coil is proposed, that is: adopting voltage feed forward control to restrain interfere of 50Hz displacement voltage, which can improve the characteristic of the injected signal significantly, make the injected signal without reference to unbalanced network and neutral displaced system. Another innovation is detecting the magnitude of neutral point signal-frequency voltage to judge the resonant state, which improves the sensitivity and accuracy of resonant judgement effectively.

基于对控制模型的分析，提出了一种新的注入变频信号的消弧线圈自动调谐方法：通过电压前馈校正控制的引入，有效抑制了50Hz工频电压对注入信号的干扰，使得注入信号不受电网不对称及中性点位移电压的影响；提出以中性点注入信号电压幅值最大做为新的谐振判据，有效提高了谐振状态判断的灵敏度和准确度。

Furthermore, the dynamic resonance adjustment method is as follows: measuring capacitive current in real-time when the grid operates in normal, tuning arc-suppression coil and making it compensate for the capacitive current completely when single-phase-to-ground fault occurs.

引言消弧线圈的作用是当电网发生单相接地故障后，提供一电感电流IL 补偿接地电容电流IC，使接地电流减小，也使得故障相接地电弧两端的恢复电压速度降低，达到熄灭电弧的目的。

The coil tube method can be well used to resolve this problem and the handled ink powder has the regular shape and good liquidity.

盘管处理方法能够很好的解决这个问题，处理后的墨粉具有规则外形和良好的流动性。
