摘　　要：发电机励磁系统灭磁装置主要包括灭磁开关和灭磁电阻,机组的结构、容量、运行方式等差异,将导致所选配的灭磁器件型号及对应的操作回路有较大差异。通过工程实例计算说明的方式,对这种差异进行比较分析,可以更加明确不同种类的灭磁器件在工程实践中的设计要点,为合理选配励磁系统灭磁装置提供参考。Generator excitation system＇s de-excitation equipment mainly includes de-excitation switch and de-excitation resistance. The differences of structure, capacity or operation mode of the unit will lead to a bigger difference between the matching de-excitation device model and its corresponding operation loop. By means of engineering practices calculation, this thesis uses the comparative analysis method to analyze these differences, thus making the key points of design of different kinds of de-excitation devices in engineering practices more clearly, and providing references for reasonable selective assembling the excitation system＇s de-excitation equipment.
