Abstract: In order to further improve the safety production of the coal mine, taking the frequency converter used in belt conveyor
as an example, based on the analysis of the internal circuit structure and fault types of the frequency converter, this paper focused
on the analysis of the tripping fault and over-voltage fault of the frequency converter in the actual production, and put forward
treatment measures in combination with the actual fault types and cause analysis, so as to lay a foundation for further ensuring the
transportation efficiency and safety of the belt conveyor.

Key words: frequency converter; belt conveyor; tripping fault; overload; overcurrent
