| Summary, etc. | This thesis investigates the performance of High Voltage Direct Current (HVDC) vacuum <br/>circuit breakers, emphasizing electrostatic and thermal analyses. The study introduces the <br/>operational principles of vacuum circuit breakers and their components, focusing on the arc <br/>extinction process and critical parameters influencing circuit breaker functionality. Various <br/>simulation models are developed to analyze key aspects such as electric field distribution, <br/>contact material properties, and thermal performance. The findings demonstrate that the <br/>enhancements in model simulation and optimization can significantly improve the efficiency <br/>and reliability of vacuum circuit breakers in HVDC applications. This research contributes to a <br/>deeper understanding of HVDC systems and identifies potential areas for future study and <br/>technology advancement in electrical power engineering. |
