摘要
电动机不同差动保护方式的选择应进行综合考虑。通过分析高压电动机的纵联差动保护及自平衡式差动保护的工作原理及其在应用中可能存在的问题,提出了在实际工程设计中应如何选择高压电机的差动保护方式。
The selection of the different differential protection modes for the motor needs comprehensive consideralion. Through the analysis on the working principles and existing problems in the application of pilot differen- tial protection and self-balancing differential protection, the measures to select the differential protection mode in the real project design are presented.
