| Abstract: | In order to treat the power supply harmonic hazards of the main well belt conveyor,the original inverter was replaced with a three-level topology inverter,and a power filter was installed,which effectively reduced the interference of harmonics on the power grid and control systems,and the harmonic voltage was controlled below 5%. |
