摘要
介绍小电流接地系统常见的几种消谐方法及其优缺点,重点介绍电压互感器(TV)中性点串接零序TV的消谐方式。对系统单相接地后一次电压相量进行详细分析和推导,介绍TV二次各种接线方式及其优缺点,根据实际运行推荐最优接线方式。
Some common harmonic elimination methods of the small current grounding system, as well as their advantages and disadvantages, are introduced, and the harmonic elimination method that the voltage transformer neutral series connection of zero sequential potential transformer is emphatically present. The primary voltage after the electric power system single-phase grounding is analyzed and derived detailedly. Advantages and disadvantages of different connection modes of potential transformer secondary wiring are analyzed, and the optimal connection mode according to the actual operation is recommend.
