Problems solved by technology
The first method is an online monitoring device based on a single-chip microcomputer. This device only monitors some state parameters of the SF6 high-voltage circuit breaker, such as SF6 pressure and SF6 humidity or the current value of the closing and opening coils; when monitoring multiple state parameters, it is necessary to Install more monitoring equipment, occupy a large space, complex wiring, and the accuracy is not high, no intelligent reasoning and health management functions
The second method is an online monitoring system based on DSP. The processing speed of these chips is faster than that of a single-chip microcomputer, and the analysis parameters are accurate, but the monitoring quantity is still single. The host computer management system only stores a single state parameter, and cannot perform multi-parameter information fusion to realize intelligent diagnosis.
The third method is based on the industrial computer. This method makes up for the incomplete monitoring parameters of the first two methods to a certain extent. It can store most of the parameter information data, but it cannot perform multi-parameter information fusion to realize intelligent diagnosis and health. management, and occupy a large space
