“…The TMF-based electrode structure has already been widely used for vacuum interrupters, which includes the following three different types: helical-slotted structure, cup-shaped structure and swastika-shaped structure [5]. Investigations of the arc behaviour patterns on the TMF-based electrode for the vacuum circuit breaker have been extensively dealt with by correlating the arc characteristics with the breaker's operating performance and are well described [6][7][8][9][10][11][12]. However, there are not many comparative studies so far in the literature in terms of the evaluation of the PJT-GS dynamic performance.…”

A plasma jet-triggered gas switch (PJT-GS) has been developed as an important piece of equipment to operate in an ±800 kV ultra-high voltage direct current transmission system (UHV DC) to achieve grid system protection and control. The crucial factors that would affect its operational performance, such as the current level the PJT-GS could withstand and the gas gap distance between the two rotating electrodes, are comparatively studied in the present work by analysing the arc dynamic characteristics. The rotating electrode used in the PJT-GS is designed with a helical-slotted structure, and the arc can be rotated circularly driven by the produced transverse magnetic field (TMF) along the electrode edge. The objective of such research is to provide a thorough study of the arc dynamic behaviour during the current flowing process of the PJT-GS and also to characterise the physical mechanism that affects the arc rotation and the PJT-GS operation performance. The magnetohydrodynamic-based (MHD) approach is applied by establishing a 3D arc model. Following such a study, the variation of arc characteristics under different operation conditions could be thoroughly determined and it also could provide the guidance for the PJT-GS optimum design reasonably to support its corresponding engineering applications.

“…A large amount of research has been carried out on these kinds of electrodes for vacuum circuit breakers. Jie Deng and et al studied the performance of the triggered vacuum arc under the TMF-AMF electrode and they pointed out that the vacuum arc maintained a diffused state with rotation on the electrode surface and the arc presented different behaviour under different current levels (5 kA∼20 kA) [6]. The research group of Yingsan Geng and Jianhua Wang put their focuses on the studies of the rotation behaviour of the TMF-based vacuum arcs [7,8] and they furtherly compared the interruption performance of vacuum circuit breaker between TMF-based electrodes and the AMF-based one [9].…”

Following the design demands of the protective switch used in ±800 kV hybrid UHVDC system, a plasma-triggered-based protective gas switch (PTGS) is developed by performing the comparative study of its dynamic performance by considering the arc dynamic behaviour induced by the transverse magnetic field (TMF)-based electrode used in the PTGS. The PTGS-based electrode, as the core component, is designed with a helicalslotted structure, the TMF could drive the arc between moving from the electrode centre to the electrode edge and then rotate rapidly along the edge. A 3D magnetohydrodynamic model (MHD) was established to computationally evaluate the effects of electrode structure variation on arc rotation characteristics. The model was verified by comparing the calculation results with experiments performed on the designed PTGS prototype. A comprehensive evaluation approach was also proposed to support the comparative analysis of the arc dynamic behaviour and estimate the arc-controlling capability of the designed electrode to further assess the dynamic performance of the designed PTGS. This approach could quantitatively estimate the arc behaviour from a spatial scale, the variation of characterised parameters such as temperature associated with arc behaviour is concerned as well, which reasonably supports the electrode optimum design and the PTGS.
