摘　　要：为优选电气化铁路牵引供电系统27.5 kV开关设备的结构形式,提高供电可靠性,通过对我国电气化铁路目前常用的网栅式安装的开关设备以及各种开关柜的经济技术和运行可靠性分析,尤其是对于小车式开关柜结构存在问题的分析,根据当前国家标准对电力系统相近类型开关设备可靠性提出更高要求的情况,提出了尽快提高电气化铁路开关设备标准、优化开关柜结构形式,改变传统的小车式开关柜结构的思维定势,大力推广形式简洁、维护方便、高可靠性的铠装固定式金属封闭开关设备的建议。To optimize the 27.5kV switching equipment's structure type in electrified railway traction power supply system,improve the reliability of power supply,this paper analyzes the technology with economy and operation reliability of grid mounted switch equipment,also analyzes a variety of switch cabinets which are commonly used in our country's electrified railway,especially analyzes the issues in dolly type switch cabinet's structure.According to the situation that the current national standards on the switchgears of similar types in power system have been put forward further requirements,this paper proposes the ideas that the electrified railway switch equipment standard should be improved,the switch cabinet's structure should be optimized,and the traditional dolly type switch cabinet's structure should be changed.Moreover,the paper proposes the advice that the armored fixed metal closed switch equipment should be popularized,which has advantages of simple structure,convenient maintenance and higher reliability
