摘要

电流互感器绝缘失效严重威胁着电网的正常运行。在总结直立式、倒置油浸式和SF6气体绝缘式电流互感器结构特点的基础上,比较了现场电气、化学和检验测试方法的有效性。研究了变压器故障对电网保护的影响,对电流互感器的运行和维护具有重要意义。

Operation characteristics analysis of different structure current transformers
The insulation failure of current transformers threatens the operation of power grid. Based on the structure characteristics summary of the upright, inverted oil immersion type and SF6 gas insulation type current transformers, the effectiveness of the on-site electrical, chemical, and inspection testing methods is compared. And the influence of the transformer fault on the power grid protection is studied, which is important to current transformer operation and maintenance.
