Single-phase power frequency alternating current moving power station auxiliary maintenance and protection device

The utility model relates to a moving power station auxiliary maintenance and protection device. The single-phase power frequency alternating current moving power station auxiliary maintenance and protection device comprises a data collection part, an MCU and storage part, an output control part and a display and sound part. A signal output by the data collection part accesses the MCU and storage part. A calendar chip is connected with the MCU in an I2C/SMBUS bus mode. The MCU uses the presence or absence of output voltage of normal work of a moving power station as timing conditions and visualizes the work time of the moving power station. The MCU is connected with the display and sound part in a parallel data bus mode. A control signal output by the MCU is connected with the output control part, and the moving power station shuts down. According to the utility model, accurate cumulative timing is carried out on the work time of the moving power station; alarm and indication are carried out on the work and r
