户内交直流双电压等级兼容接触网隔离开关上网引线的处理

Treatment of the Connection Lead of the Indoor AC and DC Dual Voltage Level Compatible Catenary Isolation Switch

中车车辆基地为满足高速铁路、城际铁路、普速电气化铁路、城市轨道交通等多种车辆调试使用的要求,一般在供电和接触网采用交直流双电压等级。以中车江门基地为例,通过交直流隔离开关上网引线对比,并对户内交直流双电压等级接触网隔离开关上网引线做法进行分析,确定户内交直流双制式兼容接触网隔离开关上网引线的处理方法,实现了交直流双电压等级兼容接触网隔离开关上网引线的安全使用。

In order to meet the requirements of high-speed railways,inter-city railways,general-speed electrified railways,urban rail transit and other vehicles,the CRRC base generally adopts AC and DC dual voltage levels for power supply and catenary.Taking CRRC Jiangmen Base as an example,through the comparison of AC and DC disconnecting switch's connection lead,the method of indoor AC and DC dual voltage level catenary isolating switch is analyzed.The treatment method of connection lead of indoor AC/DC dual standard compatible OCS isolation switch is determined,and the safe use of on-line lead of AC/DC dual voltage level compatible OCS isolation switch is realized.
