摘　　要：介绍了一种便于现场测试的三相电流互感器自动检定装置。该装置中搭建了基于电流互感器磁饱和裕度间接测量方法的电流互感器通用无级自动调节负荷模块,通过设计自动检定方法实现了三相电流互感器基本误差、磁饱和裕度等项目检测过程的自动化。设计思路及检定方法可操作性强、检定效率高、使用方便、检测结果科学准确。The paper introduced a kind of convenient testing three-phase current transformer automatic verification de- vice. Based on the indirect measurement methods of current transformer magnetic saturation margin, the device constructed current transformer general stepless automatic adjustment load module. With the designed automatic verifica- tion method, it comes true that the automation of measuring process such as basic error, magnetic saturation margin and so on. The design idea and verification have strong feasibility, high verification efficiency, accuate test results and conveniece application.
