摘　　要：直流电流不具有电磁感应能力,无法利用波的特性进行测量,因此基于各种物理原理的直流测量方法应运而生。文章梳理传统的电压测量和霍尔元件测量、应用较广的零磁通测量法以及技术最先进的磁光测量直流电流互感器。对各种直流电流互感器原理进行分析,得出相对应的应用范围和优缺点。DC current does not have electromagnetic induction ability and can not be measured by wave characteristics,so DC measurement methods based on various physical principles emerge as the times require.In this paper,the traditional voltage measurement and Hall component measurement,the widely used zero flux measurement method and the most advanced magneto-measurement DC current transformer.The principle of various DC current transformers is analyzed,and the corresponding application scope,advantages and disadvantages are obtained.
