摘　　要：精确测量直流电流是高压直流输电工程安全稳定运行的重要前提。高压直流电流互感器稳态误差校验技术是确保高压直流电流互感器测量精度的重要保证。针对目前主流运行的高压直流电流互感器并依据国家标准,文中提出了一种直流电流互感器稳态误差校验系统的设计方案,并采用相关设备搭建了误差校验系统。通过试验分析和对比,证明了该直流电流互感器误差校验系统的有效性,达到了实用化要求。Accurate measurement of DC current is very important for safe and stable operation of HVDC transmis-sion project. Considering the mainstream high voltage DC current transformer and the national standard, this study proposed a design scheme of steady-state error calibration system for DC current measurement device, and built an error calibration system. Experiment and comparison were performed, and the validity of the present steady-state error calibration system for DC current transformer was proved. It is concluded that this system meets the requirements of practical application.
