摘要
针对高压直流输电工程换流站二次控制保护屏柜日常运行维护中电流电压回路端子排二次隔离措施执行情况,对目前换流站常用的二次端子排密封措施及常见问题进行分析研究,探讨并总结换流站二次回路端子密封隔离技术。通过汇总换流站常见的需要通过端子排密封来隔离运行回路和检修回路的类型,针对不同类型隔离措施的消缺维护经验,探讨并总结出高压直流输电工程换流站的二次回路端子密封措施,以提高二次控制保护设备的运行可靠性,确保换流站二次设备运行更加安全可靠。
In view of the implementation of the secondary isolation measures of the current and voltage loop terminal block in the daily operation and maintenance of the secondary control protection panel cabinet in the converter station of HVDC transmission engineering,the sealing measures and common problems of the secondary terminal block in the converter station are analyzed and studied.The sealing isolation technology of the secondary loop terminal in the converter station is discussed and summarized.Through the summary of the common need and the type of operating circuit and maintenance circuit are isolated by terminal block sealing.Missing maintenance experience are eliminated for different types of isolation measures.The sealing measures of secondary circuit terminals in converter station of HVDC transmission project are discussed and summarized,so as to improve the operation reliability of secondary control and protection equipment and ensure the safe and reliable operation of secondary equipment in converter station.
