新建成直流接触网系统的首次送电,一直沿用逐所送电的传统方案,该方案既无法检测接触网的导通性,又无法检测上网电缆连接的正确性,本文将利用地铁直流牵引系统的特点,提出一种新的直流接触网首次送电方案:超大单边送电方案。
The new DC transmission network system for the first time power transmission, has been using the traditional program by the power transmission, the program can neither detect the continuity of the contact network, and can not detect the correctness of the Internet cable connection, this paper will use the subway DC traction system The characteristics of a new DC catenary proposed the first transmission scheme: large unilateral transmission scheme.
