变压器双套微机保护的应用

Application on Double Microcomputer Protection Transformer

文章结合沭阳县220 kV童庄变电所1号、2号主变压器微机保护的实际运行情况,着重阐述了变压器2套微机差动保护的功能、特点以及安装调试中应注意的问题。文章还建议要培养能够独立工作的微机保护检修维护人员。

Combined with actual operation condition of microcompnter-based protection for No.1 and No. 2 main transformer in 220 kV Tongzhuang Substation in Shuyang county, the paper elaborated emphatically the functions and characteristics of duel microcomputer-based differential protection of transformer as well as the problems that should be noticed in erection and commissioning. The paper also suggested the training of overhaul and maintenance people to work independently with microcomputerbased protection.
