10kV配电网故障定位系统取电与零序电流计算

摘要

Distribution network fault indicator has become a hot topic of research at home and abroad,the acquisition and calculation of zero-sequence current and the high pressure side to take power are im- portant and difficult design.The article designed a multi-winding core with air gap combined with the power electronics technology,to obtain the high pressure side of the power and zero-sequence current extraction.Experiments have verified the feasibility of this method.%配电网故障指示器已成为国内外研究的热点，其中，其高压侧取电及零序电流的获取与计算是设计的重点与难点。该文介绍了一种带气隙的多绕组的磁芯结合电力电子技术，来获取高压侧电源与零序电流的提取。并通过实验验证了此方法的可行性。
