摘要
电缆变压器是一种以XLPE电缆作为绕组的新型干式变压器,电磁和短路特性仍是此类变压器的主要特性,考虑到其绕组的特殊结构,建立了电缆变压器漏磁场的"场-路"耦合模型,并针对一台带有调压线匝的电缆变压器的轴向短路电磁力进行计算,计算结果符合变压器短路特性的基本规律,为进一步计算此类变压器的电磁和短路特性打下基础。
Cable transformer is a new type of dry transformer using XLPE cable as winding, the characteristics of electromagnet and short circuit is still its main features. The field - circuit coupling model under condition of leakage magnetic field for cable transformer was set up according to special construction of its winding and the axial short circuit magnetic force for a cable transformer with a regulating - voltage turns was calculated with the model, the results had a good accordance with the basic law of transformer, which lays the foundation for calculating electromagnet and short circuit features of similar transformers.
