On-line monitoring system for breakers

The utility model provides an on-line monitoring system for breakers, belongs to the monitoring field of electric devices, and relates to an on-line monitoring system capable of remotely monitoring breakers in real time. The on-line monitoring system for the breakers includes a breaker monitoring device (1) which is used for acquiring monitoring signals of the breakers and extracting monitoring data, a server (4) which is used for storing the monitoring data, and a terminal device (5) which is used for reading the monitoring data in the server (4), extracting monitoring parameters and assessing and monitoring running status of the breakers according to the monitoring parameters. The on-line monitoring system for the breakers can carry out remote, real-time and on-line monitoring on running status of the breakers. A user can read the monitoring data in the server (4) and process the monitoring data through the terminal device (5) to know running status of the breakers, and make a reasonable arrangement for overhaul according to the running status of the breakers.
