摘　　要：为提高抗直流偏磁(anti-DC Bias,DBI)电流互感器检定能力,配置了一套校验装置。对装置中的电流互感器、互感器校验仪、互感器负荷箱3部分进行设备配置和溯源研究,证明装置本身计量特性合格。将校验装置实际应用于DBI电流互感器检定中,采用归一化偏差方法进行比对验证,证明DBI电流互感器检定数据可靠,为今后开展DBI互感器全性能检测及全检验收工作奠定了良好基础。In order to improve the calibrating ability of anti-DC bias(DBI)current transformer,a set of calibrating device is equipped.The three main parts:current transformer,transformer calibrator and transformer load box are examined for the equipment configuration and traceability,and the results prove that the measuring characteristics of the device itself are qualified.The calibration device is applied to the verification of DBI current transformer.The normalized deviation method is adopted for comparative verification,which proves that the proposed verification data of DBI current transformer is reliable.This work is a good foundation for carrying out full performance test and full inspection of DBI transformer in the future.
