摘　　要：电流互感器在现场检定的过程中,由于一次阻抗过大、升流器及电源容量不足等原因致使一次电流达不到额定值。文中从工作原理和现场检定应用展开分析,针对3种不同原因分别提出解决方案,使一次电流达到额定值的1.2倍,达到电力互感器检定规程要求,为开展0.2S级关口计费电流互感器现场检定试验提供有力保证。In the process of the on-site calibration test of the current transformer,the test current is hard to reach to rated value because of large impedance,lack of the capacity of current regulator and power supply. As an important equipment in the on-site calibration test of the current transformer,cored structure current regulator＇s working principle and the application is analyzed in this article and solutions are proposed for three different reasons,which can make the primary current reach to 1. 2 times of the rated value,to comply with the requirements of the power transformer calibration procedure and guarantee the on-site calibration test of the 0. 2 S level charging current transformer.
