Professional source metadata, version and usage boundary.
Curated summary
A 2025 MDPI Processes paper by Chongqing University and co-authors predicting the closing time of UHV circuit breakers with disc spring hydraulic operating mechanisms, accounting for performance degradation from low-cycle fatigue of the springs. A coupled disc-spring energy-storage and hydraulic-transmission model is validated by tests, offering a method for performance and life prediction of disc spring operating mechanisms.
