维持大秦线接触网电压水平的方案探讨

Discussion on Maintaining Daqin Line Contaction Voltage Level Plan

针对大秦线3万吨重载组合列车运行试验,对大秦线牵引供电能力现状进行调查,分析大秦线接触网电压水平影响重载列车电力机车运行的因素,制定了调节牵引主变压器分接开关、适时投退电容补偿装置的解决方案,以满足3万吨重载组合列车试验期间大秦线接触网电压偏高或偏低的问题。

For the heavy load combination train running test of thirty thousand tons of Daqing train line, make an inves- tigation on the traction power supply ability status of Daqin line, analyze the contact network voltage level to affect the heavy load train electric locomotive running factors, make the branch switches of the requlating tractive main trunsformer, carrying out batching solution of the capacity compensating system to meet the proplems of astable voltage of Daqin line during thirty thousand ton heavy load combination train test.
