大秦重载铁路信号设备联锁试验重点项目探讨

Key Items in Signal Equipment Interlocking Test for Da-Qin Line

大秦线作为我国铁路发展的标志性工程、现代化煤运通道重载运输的示范性工程和既有线扩能改造的样板性工程,依靠重载技术的自主创新,在保持列车速度、密度不降低的同时,将列车重量由5 000 t提高到1万t和2万t。在电务技术方面,新技术、新装备大量开发运用,密集、复杂的信号设备改造大面积展开,信号设备联锁关键面临着前所未有的挑战。通过组织管内信号设备开通调试及处理设备电路问题,总结一些信号设备联锁试验容易发生问题需重点卡控的项目。

Datong-Qinhuangdao railway （Da-Qin line for short） is a symbol project ot Chinese heavy haul railways and a heavy-haul transportation demonstration project as a modern coals transportation channel, and the train weight of the line has been improved from 5000t to 10000t and 20000t without changing the speed and density of the line based on technical independent innovation. In the aspect of the communication and signal technologies, new technologies and equipment are developed and adopted, and lots of complex signal equipment are equipped during reconstruction of the line. So the signal equipment interlocking faces unprecedented challenges. Through the organization of commissioning and processing equipment circuit problem of signal equipment managed in the division, the paper summarizes some signal equipment interlocking test problems and projects to be controlled mainly.
