摘要
高铁电力系统供电是否可靠直接关系铁路运输能力和运输秩序,为提高高铁电力系统供电可靠性,对近三年来高铁电力设备故障典型案例进行分析,结合广西沿海高铁电力系统运行维护中发现的一系列影响供电的突出问题,提出从电力系统设计源头提高供电可靠性的对策,通过电力设备设立防火分区、接地装置改造、电缆中间接头运行环境改造、电力系统结构和防护设施优化、增设应急供电发动机等措施,保障了高铁电力系统供电的可靠.
Abstract
The reliability of the power supply of high-speed railway power system is directly related to the railway transportation capacity and transportation order.In order to improve the reliability of the power supply of high-speed railway power system,the typical cases of the failure of high-speed railway power equipment in the past three years are analyzed,and combined with a series of prominent problems relate to the power supply found in operation and maintenance of Guangxi coastal high-speed railway power system,the coun-termeasures to improve the power supply reliability from the source of power system design are proposed.The reliable power supply of high-speed railway power system has been ensured through establishment of fire protection zones of power equipment,the renovation of grounding device,operating environment of the cable intermediate joint,the optimization of power system structure and protection facilities,and the addi-tion of emergency power supply engines.
