某型航空交流发电机试车断电故障分析

Analysis on Power Failure During the Test Run of the Certain Type of Aviation Alternator

针对飞机试车过程中左侧无刷同步交流发电机发生的断电故障,结合飞机电源系统,对该故障展开分析。在分析中借助Multisim软件,对航空发电机内部旋转整流器进行单管故障仿真,对故障加以验证,最终实现故障诊断。

Aiming at that the power failure during the test run of the aviation brushless synchronous alternator on the left side and combining with the consideration of the aircraft power supply system,the analysis of the fault is carried out.With the help of Multisim software during the analysis course,a single-tube fault simulation of the rotating rectifier inside the aircraft generator is performed,to confirm the fault and implement the fault diagnosis finally.
