摘　　要：电流互感器是联络电网一次设备和二次系统的关键设备,倒立电流互感器相对于正立油浸式电流互感器而言具有诸多优点,正逐步在电网系统内大批量使用。从倒立电流互感器的结构特点出发,对其运行过程中发生的典型缺陷类型及原因进行分析,提出在设计制造阶段应重点关注的制造工艺,以提高倒立电流互感器投运后的安全运行水平。Current transformer is the key equipment connecting the primary equipment and the secondary system of the power grid. The inverted minimum oil current transformer possesses multiple advantages compared to the standing type and finds wide application gradually in the power system. In this paper,typical defects and causes of the inverted minimum oil current transformer are analyzed based on its structure features, the focus on the manufacturing process in the manufacture period is proposed to improve its safe operation level after operation.
