摘要
新安装就位即将投入运行的变压器差动保护,在设计、施工、整定过程中有可能出现各种问题,因此,对投运后的变压器差动保护实行带负荷测试是十分必要的,也是差动保护正确投入后不可缺少的试验项目。文章对变压器差动保护投运时带负荷测试内容、数据进行多方面分析判断,结合实际提出了相关处理方法。
Some potential problems may be occurred on the newly - installed transformer during the process of design, construction and setting, thus the on - load test after commissioning is rather necessary, and it＇ s an indispensable item which ensures the accurate operation of differential protection. The paper makes a comprehensive analysis on the on - load test content and data, and proposes relevant solving method combining with practical situation.
