Testability Study of Medium Voltage Rectifier Generator

The medium voltage rectifier generator is an important part of the ship's integrated power system. It undertakes the task of continuously supplying power to the ship's weapon equipment. The quality of its operation directly affects the stability of the entire power system and affects the combat effectiveness and vitality of the ship. At present, the domestic research on the testability of medium voltage rectifier generators is in its infancy, and the level of fault diagnosis and prediction of generators is not high. In this paper, FMECA is carried out on a medium voltage rectifier generator of a certain type of ship, and the typical fault mode is sorted out. Combined with the test related requirements, the evolution characteristics, symptoms and precursors and test parameters of various faults are analyzed to form the fault mode set, which lays a foundation for subsequent test design work.
