| 摘 要： | 建立了三相变四相四心柱电力变压器的数学模型,提出并证明了设计该变压器绕组阻抗所须满足的中性点接地条件与平衡条件;设计制作了该变压器实验模型,实验验证了理论分析的正确性;理论分析与实验研究表明,在设计该变压器必须满足的阻抗约束关系中,应优先满足中性点接地条件的要求.

| Abstract: | In this paper,the mathematical model of the three-phase to four-phase power transformer with a four-phase four-limb structure has been constructed;the winding impedance relations among the transformer winding impedances are analyzed;neutral point ground conditions and balance conditions,which we has to satisfy at the design stage of the three-phase to four-phase transformer,are presented and proven.An actual three-phase to four-phase power transformer experimental model is designed and manufactured.The test... |
