The invention relates to a transformer fault inspection system and method based on sound processing. The system comprises an intelligent inspection robot and an upper computer; a pickup and a lower computer are carried on the intelligent inspection robot; the pickup is used for collecting sound signals along the way in the process that the intelligent inspection robot inspects a transformer substation, and transmitting the collected sound signals to the lower computer; the lower computer is used for removing noise of the received sound signals to obtain the sound signals of a transformer, andtransmitting the sound signals of the transformer to the upper computer; and the upper computer is used for processing the received sound signals, judging whether the transformer has a fault or not and giving a judgment result. Manual inspection is replaced by the inspection robot, so that the inspection efficiency can be improved, the labor cost can be reduced, and the accuracy of a detection result can be improved through sound fault detection.
Description
technical field [0001] The invention relates to the technical field of substation fault inspection, in particular to a transformer fault inspection system and method based on sound processing. Background technique [0002] Early detection of power transformer faults was based on traditional human participation, using offline methods, and the main methods were daily inspections, preventive tests, and insulating oil tests. These methods have played a vital role in the safe and stable operation of substations, but with the continuous expansion of the grid scale, the complexity of equipment structures and the application of high-tech, these methods can no longer keep up with the needs of the development of the times. Therefore, how to reduce the intensity of manual inspection and realize unmanned inspection is an urgent problem to be solved at present. Contents of the invention [0003] The purpose of the present invention is to improve the above-mentioned deficiencies in the...
