The invention relates to the technical field of fault detection, and discloses a power distribution cabinet fault monitoring method and device, equipment and a storage medium. The method comprises the steps that historical current signals of the power distribution cabinet are collected, high-frequency noise and harmonic interference are removed, and standard current signals are obtained; performing wavelet packet decomposition to obtain sub-band signals of different frequency scales and generating a full-frequency-domain fault feature vector of each sub-band signal; a comprehensive fault detection criterion is established and serves as a target function for model training, and a power distribution cabinet fault detection model is constructed; acquiring a real-time current signal of the power distribution cabinet and performing fault detection through the power distribution cabinet fault detection model to obtain a real-time fault detection result; and constructing a fault feature sequence according to a real-
