Design of a Remote Protection System for Motor Drive

In view of problem of burnout of motors caused by installing mechanized coal sampling system at open-pit, the paper proposed a design scheme of remote protection system for motor drive. The system uses remote data collection module suitable for bad environment and KingView monitoring software to realize remote protection for each driving unit through collection, monitoring and alarm of electric parameters of each driving unit. The actual application showed that the system runs reliably and ensures precision of coal sampling.
