DAI Huai-zhi, LU Yi-hang, JIA Shen-li, et al. Design of On-line Monitoring System for Circuit Breaker[J]. High voltageapparatus, 2004, (2): 104-106.DOI:
The designed system is capable of on-line monitoring the temperature rise
insulation and mechanical characteristic of circuit breakers. It has a local monitoring unit and a computer
the former collecting local data and showing users the condition report on LCD
indicating the condition of exceeding the threshold value that can be preset by user through keyboard
and sending the data to computer through RS-485 communication interface. The application of PSD device and a software method called task schedule makes the local monitoring unit more stable and more flexible.
