摘要
文章以某换流站有载分接开关三相动作不一致故障为例,结合有载分接开关控制机理,阐述了有载分接开关控制回路步进流程。给出了相关故障出现后的一、二次设备检查策略,最后针对提高分接开关可靠运行给出了改进技术措施,可为换流站运维工作提供参考和借鉴。
This paper takes the three-phase inconsistency fault in a converter station′s on-load tap changer as an example.Combined with the control mechanism of the on-load tap changers,it describes the step process of the control loop about the tap changers and presents the strategies for primary and secondary equipment inspection following the occurrence of related faults.It finally proposes improved technical measures to enhance the reliable operation,which can serve as a reference for the operation and maintenance work of the converter stations.
