摘　　要：近年来,作为直流测量设备的直流互感器的应用越来越多,为保证直流互感器精度,直流互感器校验仪得到广泛应用。但是,随着精度的提高,缺乏相应设备对直流互感器校验仪进行校准。文中基于微差法原理,研制一套高精度直流互感器校验仪整体检定装置,可以对0.05级直流互感器校验仪进行校准。此装置由国家级校准机构进行校准,校准结果证明此装置准确度优于0.01级。As DC measurement equipment,DC transformers have been increasingly used in recent years.In order to ensure the accuracy of DC transformers,DC transformer calibrators have been widely used.However,with the improvement of accuracy,there is a lack of relevant equipment to calibrate the DC transformer calibrator.Based on the principle of differential method,a DC transformer calibrator integral verification device with high accuracy is developed in this paper,which can be used to calibrate a 0.05 level DC transformer calibrator.The device has been verified by a national calibration agency,and the verification results confirmed that the accuracy of the device was better than 0.01 level.
