摘要
通过对1台500 kV SF_6绝缘电流互感器一次典型故障的分析,阐述其故障原因,在该故障情况下保护动作行为和存在的问题。提出了保护设计和SF_6电流互感器在制造、应用中应采取的改进措施。
According to analysis on a typical failure of a 500 kV SF6 insulated current transformer the paper illustrates the failure cause, protective actions under the failure and existing problems. The paper also points out the protective design and improving measures to be taken in manufacture and application of SF6 CT.
