摘　　要： 真空断路器是中低压配电网中最重要的电气设备之一,其运行的正常与否直接影响着整个系统的稳定性和可靠性。因此,对真空断路器进行在线监测的研究,及时发现真空断路器运行过程中存在的隐患,做到防患于未然,具有非常重要的意义。 本文分析总结了目前真空断路器在线监测所涉及到的触头电磨损监测、真空度监测、机械性能监测、绝缘性能监测等项目的实现算法和方法,并在前人研究的基础上对其进行了完善和创新;同时分析了信号采集过程中各种可能的干扰,并提出了确保所采集信号的失真度在允许范围之内的数据处理方法。 The vacuum circuit breaker is one of the most important electric equipments in middle and low voltage domain of power distribution network,the normal or abnormal operation of which is of a direct impact on the overall system's stability and reliability.Therefore,it is great significant to study on-line monitoring of vacuum circuit breaker,and detect vacuum circuit breaker is running risk or not in time,so that we can take precautions before it is too late. This paper analyzes and summarizes the current algorithms and methods of on-line monitoring of vacuum circuit breaker,which involve the monitoring of contacts' electrical wear,degree of vacuum,mechanical performance and insulation performance and so on.And previous studies carried out on the basis of the improvement and innovation;At the same time, the paper analyzes a variety of possible interferences during the process of collecting the signals,and proposes the data-processing method to ensure that the collected signals' distortion is in the allowed range.
