Anti-interference electricity structure and method for frequency converter

Abstract

The present invention discloses an anti-interference electricity structure for frequency converter. The structure comprises a UPS machine, a base is arranged at the bottom end of the UPS machine, the UPS machine is connected to the upper end of the base through bolts, a storage battery box is arranged on the side, away from the UPS machine, of the upper end of the base, the storage battery box is connected to the upper end of the base through bolts, and a storage battery is placed in the storage battery box. Limiting mechanisms are arranged on the two sides of the storage battery and located in the storage battery box. The anti-interference electricity structure has the advantages that the storage battery is arranged, the UPS is connected to the power supply system of the frequency converter, when the power supply system has the interference electricity phenomenon, the UPS can provide a back-up power source for the frequency converter, the interference electricity phenomenon is prevented from being continuously generated, and when the power supply input of the UPS is normal, the UPS machine stabilizes the voltage of the power supply and supplies the power supply to the connected equipment for use, and charges the storage battery on the base at the same time; and when the power supply is insufficient, the storage battery supplies power to the UPS machine, so that the UPS machine maintains normal work, the normal voltage is ensured, and the electricity interference phenomenon is avoided.

Description

Technical field [0001] The present invention relates to an anti-shake drive electrical configuration of the related art, in particular to a structure and method of electric drive with an anti-shake. Background technique [0002] Inverter is a regulated voltage and frequency output power of a power control apparatus also has overcurrent, overvoltage, overload protection function, the inverter is widely used in various mechanical devices, with the increasing degree of industrial automation, inverter has been very widely used, Akira electrical phenomenon is due to an unstable power system will cause voltage fluctuations than momentary or short outages and restoration, when inverter, Akira electrical phenomena may cause the inverter the motor is stopped, the user is now typically provide backup power to the drive by loading the UPS unit, it will not instantaneous voltage drop, in order to maintain the normal operation of the inverter, Akira eliminate interference power. [0003] Unde...
