摘要
自20世纪60年代以来,真空开关在中压领域的占有率已超过85%。今后,真空开关的发展趋势是真空灭弧室向小型化发展、真空开关向高电压等级和低电压等级发展。文章还介绍了真空开关在其他方面的研究开发情况, 其中,对真空灭弧室触头材料的研究情况作了重点介绍。
Since 60' s of 20th century, the rate of vacuum switch in the field of Medium Voltage has exceeded 85% . The development tendency of vacuum switch in the future is to miniaturize vacuum extinction chamber and develop high voltage vacuum switch and low voltage vacuum switch. The paper introduced some research devetopments of vacuum switch in other aspects, in which the research & development of contact material for vacuum extinction chamber was made a key introduction.
