【摘要】 大型单相自耦变压器常常会有半匝效应，引起变压器损耗的异常增加。本文中作者通过对一台35kV三相五柱式变压器高压绕组首末端出头不在同一侧时的理论研究与仿真和测试结果，指出当绕组首末端出头不在同一侧时应注意半匝效应对损耗的影响。更多还原

【Abstract】 Large single-phase auto-transformer often has a half-turn effect, resulting in an abnormal increase in transformer loss. Based on the theoretical research, simulation and test results of a 35kV three-phase five-column transformer, pointed out that the influence of half-turn effect on load loss should be paid attention to when the ends of the high voltage winding is not on the same side.更多还原
