摘要
结合工程案例,针对正线非端部牵引变电所,从供电牵引电流计算、直流保护整定、运营实际情况等方面,对DC1500V电流速断保护(Imax)相关影响因素分别作了分析,提出了非端部牵引变电所直流速断保护Imax整定取值建议、以及运营部门应重点采取的措施。
With reference of the cases of projects, and with respect of mainline non-end traction substation, and on aspects of calculation of power supply traction current, setting of DC protection and the actual operation situations, the correlative factors affecting DC 1 500 V current quick breaking protection （Imax） have been analyzed, and the proposals for setting values of DC current quick breaking protection Imax of non-end traction substation and the measures taking for the operation sector have been put forward.
