Abstract
- In this study, an unsymmetrical bistable multi‐magnetic circuit permanent magnetic actuator is proposed. The operating principle and mathematical model of the high‐voltage circuit breaker with the proposed machine are analysed. Additionally, the static and dynamic characteristics of the high‐voltage circuit breaker with the presented machine are investigated and evaluated using numerical finite element analysis methods. Furthermore, the influence of the length of the middle gap and the additional coil in the proposed machine are studied. The advantages of the presented machine, such as less magnet volume, low cost, high force density, and short starting time, are discussed. Finally, a prototype is created and tested, followed by the retrieval of the characteristic curves of the holding force to confirm the proposed design. [ABSTRACT FROM AUTHOR]
