The distribution transformer operation sound database can be gradually established by collecting the sound data of the distribution transformer operation and utilizing the big data analysis function, and abnormal sound of the distribution transformer operation can be analyzed in time.

Analysis and research show that the sound abnormity judgment of the transformer has the following points: 1. the transformer operates normally, and due to the action of the alternating magnetic field of the transformer, the transformer generates buzzing sound which is deep and regular. 2. The sound of the transformer is abnormal due to the fact that fasteners, bolts and the like are not firmly connected or loosened in the installation and manufacturing processes of the transformer, the sound of the transformer is crisp and uneven, the abnormal change usually occurs at a certain part of the transformer instead of the whole transformer, and the abnormal change generally cannot harm the transformer. 3. The abnormal sound of the transformer caused by the looseness of the silicon steel of the transformer is sharp and uniform, and the local eddy current heating and local overheating can be caused after the insulation of the silicon steel sheet is abraded due to the vibration of the silicon steel sheet. 4. The local insulation breakdown of the transformer generates sound of frizzy sound by small current discharge, and the sound is fine and dull. 5. And (3) internal fault of the transformer: if the sound of glugging oil boiling inside the transformer is found and the temperature of the transformer oil rapidly rises, the transformer is immediately stopped when the transformer protection is not moved due to a serious short-circuit fault inside the transformer. 6.
