报告讲述电力真空开关从1920年代在美国加州理工学院诞生以来的百年恢宏历史。报告包括三个方面的内容：电力系统与电力开关、电力真空开关的诞生、以及真空开关如何改变电力系统的未来。该报告一方面介绍电力真空开关技术的发展历程，另一方面突出其中的关键人物，包括世界上第一台真空开关的创始人－美国加州理工学院索伦森教授，世界上第一台真空断路器的发明者－交通大学校友李天和，“中国真空开关之父”－西安交通大学王季梅教授等。最后讨论电力真空开关技术正在改变电力系统的未来：发展高电压等级真空断路器有望减少强温室效应气体SF６的排放、超高压快速真空断路器可以显著提升电力系统暂态稳定性，快速真空开关可实现相控投切以降低电力系统开关操作引起的暂态等。

The report covers the 100-year history of the electric vacuum switch since its birth at Caltech in the 1920s. The report covers three areas - the power system and the power switch, the birth of the power vacuum switch, and how the vacuum switch is changing the future of the power system. The report introduces the development of power vacuum switch technology and focuses on key figures such as Professor Sorensen of Caltech, known as the founder of the world's first vacuum switch; Li Tianhe, the inventor of the world's first vacuum circuit breaker; and Prof. Jimei Wang of Xi'an Jiaotong University, an alumnus of Jiaotong University who is also known as the Father of China's vacuum switch. Finally, how vacuum switchgear technology is changing the future of power systems is discussed. The development of high-voltage vacuum breakers is expected to reduce the emission of SF6, a strong greenhouse gas. Ultra-high voltage fast vacuum breakers significantly improve the transient stability of power systems, and fast vacuum switches can realize phase-controlled switching to reduce transients caused by switching operations in power systems.
