摘　　要：采用可连续调节的消弧线圈不仅解决了高压电感调节系统的价格昂贵和调节系统十分复杂的问题 ,还可以使经消弧线圈接地系统的优越性充分发挥。文中着重介绍了如何采用低耐压的晶闸管连续调节 6～ 6 6kV的消弧线圈的一种新方法。对新型消弧线圈的电感调节量的计算进行了理论推导 ,并对其产生的稳态电流谐波分量进行了分析 。The paper presents a novel continuously adjustable Peterson coil. If it is used in the system of neutral point grounding through Peterson coil, not only the high price can be reduced and the complicated problems can be solved of which the high voltage inductance controlling systems, but also advantages of the system of neutral point grounding though Peterson coil can be shown. It is introduces that how adopts low voltage thyristors for continuing adjusting inductance of the Peterson coil of which the voltage level ranges from 6 kV to 66 kV. This paper discusses the formula of calculating the inductance variable ranges and the harmonic currents which presents stable harmonic current under the phase controlled mode also. The theory of the designing coil is verified by the Saber simulation and practicality experiment.
