Description

technical field [0001] The invention relates to a detection test equipment and method of a combined transmission generator of a military aircraft, in particular to a detection device and a detection method of a rectifier diode of a combination transmission generator. Background technique [0002] In the monitoring and maintenance of combined transmission engines of military aircraft, the excitation current cannot reach the required value. The main reason is due to the failure of high-power rectifier diodes. At present, there is no effective detection test method, so in each test, it is necessary to judge whether the rectifier diode is invalid by interpreting the output data of the generator and relying on the usual maintenance experience, but this method cannot accurately determine the number of high-power rectifier diode failures, and for some Invisible faults are difficult to accurately determine. Therefore, it is impossible to determine the number of failures of high-po...
