Abstract

The invention relates to a power supply protection system and a magnetic levitation blower. The system comprises a power supply conversion module of which the input end is used for connecting an external input power supply; an uninterruptible power supply of which the input end is connected with the output end of the power conversion module; a seamless power supply converter of which the first input end is connected with the output end of the uninterruptible power supply, the second input end is connected with the output end of the power supply conversion module and the detection end is used for connecting a controller; and a first DC stabilized power supply of which the input end is connected with the output end of the seamless power supply converter and the output end is used for connecting the magnetic levitation system for maintaining the suspension of the motor spindle. The system can generate a warning effect in time when the uninterruptible power supply fails and can seamlesslyswitch the power supply so as to enhance the power supply protection mechanism of the power supply and improve the power supply reliability.

Description

technical field [0001] The present application relates to the technical field of magnetic levitation blower, in particular to a power supply protection system and a magnetic levitation blower. Background technique [0002] The magnetic levitation blower can provide air to the sewage biochemical system and provide the dissolved oxygen required by the activated sludge microorganisms to ensure the oxygen demand of the microbial metabolic process. Compared with traditional blowers (such as Roots blowers), magnetic levitation blowers have the advantages of energy saving and high efficiency. When the magnetic levitation blower is started and running, the main shaft of the motor is controlled by the magnetic levitation system to levitate, and the frequency converter is used to supply power to the motor to control the rotation of the main shaft of the motor. Since the motor shaft is suspended, the wear of the shaft is small and the speed is fast. However, when the power supply (suc...
