宁波轨道交通3号线信号系统电源设备加强措施

Strengthened Measures for the Signal Power Supply Equipment of Ningbo Rail Transit Line 3

宁波轨道交通3号线采用LTE(长期演进)综合承载信号系统和专用无线系统。为了确保方案的可靠性,对LTE设备供电方案进行了优化加强。在非集中站,采用了双套UPS(不间断电源)输出双母线的方案;采用蓄电池供电分时下电,满足不同的UPS供电时间要求;对正线及OCC(运营控制中心)的所有LTE设备,经过计算分析,采用综合供电方案。

Ningbo rail transit Line 3 adopts LTE integrated bearer signal system and the dedicated wireless system.To ensure the reliability,the power supply solution for LTE equipment is optimized and strengthened.At the decentralized stations,a dual UPS and output double bus set is adopted,which uses battery time-sharing TOU power down to satisfy the time requirements for different UPS power supply.For the positive line and all LTE devices in OCC(operating control center),the integrated power supply plan is adopted through calculation and analysis.
