Abstract HV Frequency conversion retrofit for powder exhaust fans and booster fans were carried out in Guangzhou Wanglong Thermoelectricity Co.Ltd.,In order to ensure the reliability of the equipment, the automatic bypass was used in high-voltage inverter. Firstly,the switching strategy of automatically bypass is described in this paper, including the interface between inverter and DCS, DCS Logic of VF-FF switchover and override control of damper.Then the protection configurations is introduced. Finally, the switching effect of high voltage inverter is analyzed.
