摘要:
对某地铁列车在线时发生的接触网短路跳闸故障进行了分析。详细描述了故障的发生过程及故障特征，建立了整流机组等效电路模型并对其短路过程进行了分析。同时对短路引起的电压变化与反向大电流给出解释，提出保护设计与应急处置的建议。
Abstracts:
In this paper, a catenary short circuit fault is analyzed in-depth when a locomotive is on-line running. The process and characteristics of the fault are described in detail, and an equivalent circuit model of rectifier unit is established to analyze the short circuit process. Then, the voltage changes and reverse high current caused by short circuit are explained, relevant protection design and emergency disposal measures are proposed.
