The invention relates to a local discharge pulse separating method for high-voltage power equipment, and belongs to the technical field of high-voltage equipment monitoring. The method comprises the following steps: acquiring a local discharge pulse sequence of which the amplitude surpasses a set threshold value from the high-voltage power equipment to obtain a local discharge spectrum phase diagram of the high-voltage power equipment according to the sequence and a corresponding power frequency voltage phase; extracting waveform factors, equivalent durations and equivalent efficiencies from the sequence, solving average values respectively, and normalizing by taking the average values as factors; drawing a feature spectrogram of KT, KF, TF and KTF according to a processing result; classifying the discharge types of discharge pulses on the feature spectrogram, and drawing local discharge spectrum phase diagrams of different discharge types according to the mapping relation between the type of the feature spectrogram and the discharge spectrum phase diagram. By adopting the method, the separating accuracy of different types of local discharge pulses is increased. The method plays an important role in local discharge offline measurement, electrified detection, online monitoring and fault diagnosis of the high-voltage power equipment.
