摘　　要：阐明了船用发电机保护用电磁式脱扣器与智能型脱扣器的工作原理。解释了短路电流非周期分量对电磁式脱扣器和智能型脱扣器产生影响的原因。提出了电磁式瞬时保护和智能型瞬时保护克服非周期分量影响的对策。The work principles of electromagnetic and intelligent release controls used in shipboard generator protection were clarified. The reasons were explained that non-periodic components in short circuit current have influence on electromagnetic and intelligent release controls. At last, the countermeasures were put forward that electromagnetic and intelligent instantaneous protections overcome the influence of non-periodic component in short circuit current.
