Operational Performance of the Cross-Connected Traction Transformer (Ⅱ)-- Calculation of Voltage Losses and Measurement Verification
Author(s): 
Pages: 12-17,26
Year: Issue:  10
Journal: TRANSACTIONS OF CHINA ELECTROTECHNICAL SOCIETY

Keyword:  电气化铁道牵引变压器AT供电系统电压损失;
Abstract: 利用已推导出的公式,对十字交叉接线牵引变压器的电压损失进行了计算,通过与现场实际测试的对比,验证了电压损失计算公式的正确性,说明所采用的数学模型是实用有效的.十字交叉接线变压器与YNd11接线变压器类似,滞后相电压损失大于引前相.分析了大秦线电气化铁道采用十字交叉接线变压器的延庆牵引变电所55kV母线电压偏低的原因,并对改造方案进行了简要讨论.
