摘　　要：5000A电流互感器现场校验时由于一次回路线路长,导致电流互感器现场试验升流困难。针对以上情况提出了在升流装置原边并联电容器的无功补偿方法,使得感性无功和容性无功互相平衡,从而有效地降低了现场试验对电源调节器以及升流装置的容量要求,实现了电流互感器全量程现场误差试验,达到了现场试验实用性、经济性、高效性相统一的目的。During the on-site verification of 5000A current transformer,due to the long primary circuit,it is difficult to increase the current in the field test of the current transformer.Aiming at the above situation,a reactive power compensation method of a parallel capacitor on the primary side of the current-raising device is proposed to make the inductive and capacitive reactive powers balance each other.Therefore,the capacity requirements of the power supply regulator and the current-raising device in the field test are effectively reduced,and the full-scale field error test of the current transformer is realized,and the purpose of integrating the practicality,economy and efficiency of the field test is achieved.
