In this paper, a novel asymmetrical bistable short mover permanent magnet actuator is presented. The comparisons between the presented machine and the asymmetrical structure bistable permanent magnet actuator are introduced. The static and dynamic characteristics of the high-voltage circuit breaker with the presented machine are calculated and discussed. The influences of the length of the mover and the initial mover position in the presented machine are studied and researched. The merits of the presented machine, such as less permanent magnet volume, low cost, small mover mass, and high starting speed, are researched and discussed. The Genetic Algorithm is used to optimize the presented machine. Finally, a conventional permanent magnet actuator prototype is created and tested on account of the limited experimental conditions. The characteristic curves of position versus retaining force are acquired to confirm the proposed design.

The dynamic characteristics of hydraulic operating mechanism is of great significance to the reliability of high-voltage circuit breaker (HVCB). Due to the lack of co-simulation models considering the coupling links of different physics, previous research works were limited to the analysis of some discrete parts. The purpose of this study is to propose a novel technique for the co-simulation of hydraulic operating mechanism (OM). For that aim, lumped parameter method is adopted for the modeling of hydraulic system and finite element analysis method is employed for that of transmission mechanism. Then, distributed parallel type co-simulation framework is applied, and the coupling links between different subsystems are achieved by input-output variables exchange with shared memory. Simulation and experimental validations are implemented in a 550KV HVCB. It proves that co-simulation model can accurately capture the dynamic responses of hydraulic OM, including predicting the dynamic responses under different operation parameters and quantifying important features like stress distribution and dynamic responses evolution.

The vibration signals of a circuit breaker (CB) contain important action timing information. The optimisation of features extraction for vibration signals generated during the operation process of CBs is crucial for rapid defect location and identification for CB. The authors propose a new feature optimisation method, defined as energy trajectory entropy of vibration signals via tracing the action characteristics of the main shaft of CBs. Firstly, an image tracking algorithm is employed to dynamically capture the key frames of the high‐speed image sequence of the main shaft and accurately divide the action sequence. The “cluster” instantaneous energy waveforms of the vibration signal, divided by zones, are then diffused by the twiddle factor in the polar coordinate sub grid area, while the energy trajectory entropy algorithm (ETE) is utilised to investigate the subtle changes in the energy release process. The ETE scale parameters are optimised using a support vector machine identification model. This enables rapid location of defective components in CBs, resulting in a significant reduction in time cost. The experiment has confirmed the strong feature correlation between CBs action and vibration signals, offering new ideas for achieving non‐invasive defect identification of CBs.
