摘　　要：一定的真空度是保证高压真空断路器在操作时熄灭电弧的前提,而真空度在工作中会因为一些原因下降,因而需要时常检测,传统的离线检测方法需要停电具有诸多不便,在线监测技术解决了这些问题。本文设计了一套真空度在线监测装置,计算机仿真结果显示该系统能够准确完成真空度的在线监测报警显示。A certain vacuum degree is the premise to guarantee the high voltage vacuum circuit breaker in operation,and the vacuum degree in the work will be reduced because of some reasons,and therefore need to detect,the traditional method of off-line detection requires a lot of inconvenience. In this paper,a set of on-line monitoring device is designed.The computer simulation results show that the system can accurately complete the on-line monitoring and alarming of the vacuum degree.
