摘　　要：地铁直流1 500 V接触轨供电系统中,需配置计量器具,定期测量供电系统运行参数,以保障直流1 500 V接触轨供电系统向地铁列车稳定、可靠供电。为了保障计量器具的量值准确、可靠,需对这些计量器具进行量值溯源。目前,对这些计量器具量值溯源研究非常少。为此,分析地铁直流1 500 V接触轨供电系统中计量器具的选择,探讨计量器具的量值溯源,为地铁直流供电系统中计量器具的量值保证提供参考。DC 1500 V contact rail power supply system in metro,measuring instruments must be configured to regu⁃larly measure the operating parameters of the power supply system to ensure stable and reliable power supply to metro trains.To ensure the accuracy and reliability of the measuring instruments,it is necessary for traceability of the value of quantity.At present,there are few studies on traceability of the value of quantity for these measuring instruments.Therefore,the selection of measuring instruments DC 1500 V contact rail power supply system in metro is analyzed,and traceability of the value of quantity for measuring instruments is discussed to provide reference for the guarantee of the value of quantity for measuring instruments in metro DC 1500 V power supply system.
