摘要
阐述了大型直流电机不能采用GB1311-89介绍的四种短路加载方式时,采用西门子短路法进行无火花换向区域的测定试验,经多年实践证明是安全可靠的。
This paper describes that the determination test of non-sparkling commu- ration area by short-circuited method of Siemens due to the short-circuited loading method in GB 1311-1989 not being applied to large-sized d. c. electric machine. It is proved that the determination test is safe and reliable by practice.
