| titleOfInvention | Asynchronous motor rotor broken bar fault detection method, device, equipment and medium |
| abstract | The invention relates to the technical field of fault detection of asynchronous motors, and in particular provides a method, device, equipment and medium for fault detection of rotor broken bars of asynchronous motors, aiming at solving the problem of accurately detecting rotor broken bars faults. The method of the present invention includes sliding a sliding window of a preset size according to a preset sliding step in the sequence of the first-to-last sequence of the voltage acquisition time of one-phase power supply, and calculating the voltage fluctuation according to the voltage value falling into the sliding window after each sliding. coefficient; if the minimum voltage fluctuation coefficient is less than the coefficient threshold, the instantaneous reactive power is calculated according to the three-phase stator current and three-phase supply voltage obtained at the time of collection of the voltage value corresponding to the minimum voltage fluctuation coefficient. for The power component is determined to have broken rotor bar fault, represents the slip rate, Indicates the power supply frequency. Through the above-mentioned embodiments, it is possible to accurately detect whether the rotor bar failure occurs in the asynchronous motor under the condition of voltage fluctuations in the supply voltage. |
