摘要
逐个分析了将三相转换成单相电源的 8个变压器专利方案的平衡效果 ,指出了单纯依靠变换绕组联结和铁心结构 ,是消除不了单相电力负载的不对称后果的 ,并提出了消除负序磁势的新思路和新结构。
The equilibrium effects for eight patent schemes which are related to transfer the power from three phase into single phase. The paper points that it's not possible to eliminate asymmetry of single phase power load of transformer only by the means of variating the winding connection and adopting the special structure of core. The new thinking and structure used for eliminating negative sequence magnetic potential are proposed.
