广深高速电气化铁路自正式开通以来 ,仙村、樟木头分区亭断路器在牵引网发生短路、保护动作跳闸后 ,从未自动重合。运用DIGSI软件对西门子保护的报告和故障波形进行分析 ,确定了分区亭自动重合闸不起动的原因 ,为恢复自动重合闸的正常动作提供了解决办法。 Since the formal opening of the Guangzhou-Shenzhen high-speed electrified railway, the circuit breaker of Xianmu and Zhangmutou district pavilions have not short-circuited automatically in the traction network and have never been automatically overlapped after the tripping of the protection operation. Using DIGSI software to analyze the reports and failure waveforms of Siemens protection, the reason why the autoreclosure of the district kiosk can not start is determined, which provides a solution to the normal operation of autoreclosure.
