摘　　要：当发动机出现故障需要检修,或发动机熄火后需要打开点火开关供电时,为了有效地保护激磁绕组,避免蓄电池长时间放电造成亏电的情况,本研究提供了一种汽车交流发电机激磁绕组电路保护装置,在发动机熄火后,打开点火开关,可避免蓄电池长时间向激磁绕组供电的危险。When the engine fails and needs to be overhauled,the ignition switch needs to be opened after the engine is extinguished.In order to effectively protect the excitation windings,the long time discharge of the battery can prevent the loss of electricity.In this study,a protective device for motor alternator excitation winding circuit is proposed.After the engine is extinguished,the ignition switch is opened to avoid the risk of battery power supplying to the excitation winding for a long time.
