Description

technical field [0001] The invention belongs to the technical field of testing, and more specifically relates to a fault simulation device for a rectifier generator set. Background technique [0002] Testability is an important link between equipment reliability design and maintainability and support design. The system and equipment with good testability can prompt the operator to interrupt the task in time when a fault is found, improving the reliability and safety of the equipment; at the same time, it can quickly detect and isolate faults during the maintenance support process, shortening the fault detection and isolation time , thereby reducing maintenance time, improving system availability, continuity and rapid response capabilities, and reducing maintenance costs. [0003] However, testability must be based on fault diagnosis technology, and the fault injection design of fault simulation rectifier generator sets came into being. This invention can inject faults into ...

Problems solved by technology

[0005] The main reason for the low level of testability of existing equipment and the in-depth application of testability technology is that the reliability of testability verification test results is not high. It often takes a long time to naturally generate faults through field verification tests, and the types of faults generated are less , the fault produces an uncontrollable

At present, the main method of testability verification is fault injection, but rectifier generators lack effective fault injection methods
