高电压技术发展现状及展望

High voltage technology is an important subject that combines applied science and experimental technology, and it focuses on physical phenomena, development laws, and industrial applications under the action of high voltage. Its main research contents in modern times include high voltage insulation technology, high voltage test technology, over-voltage and insulation coordination technology, etc., and it plays an important fundamental role in the field of electrical engineering. Over the past 20 years, high voltage technology has made tremendous progress and achieved fruitful results in basic theory and engineering applications. These achievements have not only supported the implementation of the national strategy of west-to-east power transmission, but also promoted the development and utilization of new energy and the construction of new power systems, making important contributions to China’s breakthroughs in AC/DC ultra-high voltage (UHV) transmission technology for long-distance and large-capacity power transmission. In this paper, the research results and development status of discharge basic theory research, computational high voltage engineering, high voltage electrical materials, UHV transmission technology, high voltage equipment technology, high voltage measurement and sensor technology over the past 20 years are reviewed, the problems existing in current researches are pointed out, and the future development of high voltage technology is summarized and prospected.
