高压真空断路器在我国供电系统中的应用始于1978年，其重量轻，结构简单，使用寿命长等优点很快被电力部门运行、检修和技术人员认可。早期国内生产的高压真空断路器质量不够稳定，操作过程中载流过电压偏高，个别真空灭弧室还存在有漏气现象。至1992年天津真空开关应用推广会议时，我国真空断路器的制造技术已经进入了国际同行业同类型产品的前列，成为我国高压真空断路器应用，制造技术新的历史转折点。

The application of high voltage vacuum circuit breaker in China's power supply system began in 1978. Its advantages, such as light weight, simple structure and long service life, are quickly recognized by the operation, maintenance and technical personnel of the power department. The quality of high-voltage vacuum circuit breakers manufactured in China in the early stage is not stable enough, the overvoltage oshijiazhuang.71ix.cnwww.juanzhiji.com.cnwww.dianzugui.com.cnwww.shoutao.org.cnwww.qibiji.org.c

By the 1992 Tianjin Vacuum Switch Application and Promotion Conference, the manufacturing technology of vacuum circuit breaker in China has entered the forefront of the same type of products in the international industry, and has become a new historical turning point in the application and manufacturing technology of high voltage vacuum circuit breaker in China.
