摘要
不对称接线平衡变压器结构简单,材料利用率高,是特别适合电气化铁道直供和BT供电方式的新型变压器.鉴于此,首次研制了一台2 kVA不对称接线平衡变压器模型,进行参数测量,空载、负载等试验,并对试验结果进行了分析.理论推导结果、设计值和试验结果是一致的.表明不对称接线平衡变压器理论分析的正确性和实施方案的可行性,为不对称接线平衡变压器的进一步应用推广打下坚实基础,对其他新型平衡变压器的研制具有重要的参考价值.
The balanced transformer has simple structure and high material utilization rate,and is especially suitable for the new transformer of the direct power supply and the BT power supply mode of the electrified railway. A 2 kW balanced transformer model is developed,and the parameters of the model are measured. Noload and load tests are done. The experimental results show that the theoretical analysis and the feasibility of the implementation scheme are correct. The balance transformer has important reference value for the development of the new balanced transformer.
