摘要

以人工过零法进行了用ZN3—10/600—150型、ZN4—10/1000—200型和ZN—10/1000—300型高压交流真空断路器单个灭弧室成功地开断8、11和15.5kA直流电流

以及用两台ZN4—10/1000—200型断路器灭弧室两串三并开断直流电路

最高开断参数达25.8kA、26.7kV的试验。对具有纵向磁场的ZNN—10型（暂）真空断路器

在固定开断电路参数的条件下

进行了单个灭弧室连续开断直流电路的试验

为50kA、30kV高压直流断路器的建造奠定了试验基础。

Abstract

By artificially producing current zero the single arc-extinguishing chambers of the HV ac vacuum circuit breakers ZN3 -10/600-150

ZN4 -10/1000 - 200 and ZN -10/1 000- 300 have successfully breaked dc current of 8kA

11kA and 15. 5kA respectively

whilst the 25. 8kA/27kV dc circuit is interrupted by 6 chambers in parallel and series. The repeatedly breaking tests of single arc-extinguishing chamber with longuitudinal magnetic field is completed. These results give important information to develop the 50kA/30kV vacuum circuit breaker.
