摘　　要：换流站中性区域直流电流测量多采用零磁通电流互感器,零磁通电流互感器故障将导致直流系统单双极闭锁。介绍了零磁通电流互感器结构、原理,分析了零磁通电流互感器常见故障原因,提出了零磁通电流互感器运维提升措施。Zero-flux current transformers are mostly used for the measurement of the neutral area DC current in the converter station.In this paper an introduction to the structure and principle of zero-flux current transformer is given and the causes for common faults of zero-flux current transformer are analyzed,finally the improvement measures in operation and maintenance of zero-flux current tran sformer are put forward.
