高电压真空断路器的发展

摘要

六氟化硫断路器在高压断路器中居主导地位,而真空断路器在中压领域占绝对优势,并在高电压领域崭露头角。阐述了开发高电压真空断路器的必要性,介绍了现有产品的结构与特点,并提出了研发高电压真空断路器需解决的技术问题及相关的应对措施。%Sulfur hexafluoride circuit breakers take a leading position in high-voltage circuit breakers and vacuum circuit breakers hold all the trumps in medium voltage field,making a figure in high-voltage field.Description was made to the necessity of development of high-voltage vacuum circuit breakers.Introduction was made to structure and features of the existing products.This paper raised technical issues to be solved in RD of high-voltage vacuum circuit breakers and their related countermeasures.
