在分析国内外高电压等级真空开关的总体现状的基础上,对多断口真空开关技术的发展与研究现状进行了综述,研究了多真空间隙串联的静态绝缘特性、多断口真空开关的动态绝缘特性及对多断口真空开关的操动机构及控制系统3个方面的内容。认为在解决各断口均压分布及同步问题后,多断口真空开关技术是实现高电压等级真空开关的合理选择.
On the basis of analyzing the overall situation of high voltage vacuum swith both in china and abroad, this paper overviews the development and current status of vacuum switch with multiple breaks. It consists of three parts: the static dielectric characteristic, the dynamic dielectric characteristic and the actuator with the controller system. It is proposed that the technology of vacuum switch with multiple breaks is a reasonable choice for higher voltage level application, after solving the problems of synchronous as well as voltage distribution in every break.
