研究目的
To study the interruption capacity of LTVS with different electrode configurations.
研究成果
The study concludes that the interruption capacity of LTVS is significantly influenced by electrode configurations, with TMF electrodes showing better performance than AMF electrodes but being more susceptible to electrode spacing. The polarity configuration's effect on interruption capacity is closely related to the target material, with KCl + Ti under positive polarity showing better performance. The findings provide valuable references for the design of LTVS products.
研究不足
The study focuses on the interruption characteristics of LTVS with specific electrode configurations and materials, and the findings may not be directly applicable to other configurations or materials. The influence of external factors like environmental conditions on the interruption capacity is not considered.
