新型平衡变压器的平衡条件及等值电路研究

STUDY OF REQUIREMENTS AND EQUIVALENT CIRCUIT OF NEW BALANCE TRANSFORMER

分析了Ｙ／＞／新型平衡变压器对称短路时高压侧三相输入阻抗平衡所必须满足的条件，导出了这种新型平衡变压器的等值电路，并据此分析其运行特性。

This paper discusses the requirements that must be satisfied to keep the impedances of the three phases of the primary side balanced,when Y/>/ connected balance transformer is under symmetrical short circuit,thus deriving the equivalent circuit and analysizing the operating characteristics of this new type of balance transformer.
