Embodiment
[0040] see figure 1 and figure 2 , the present invention provides a technical solution: a method for locating a sound source of a transformer fault based on a microphone array, comprising the following steps:
[0041] S1. Obtain the acoustic signal x(t) at the measurement surface through the microphone array;
[0042] S2. Use the improved multi-scale morphological filter to perform noise suppression on the acoustic signal x(t), and obtain the filtered denoising signal That is, the transformer equipment in a pure state radiates noise signals. Since there is often more than one kind of interference noise in the sound field where the actual transformer equipment is located, and the interference noise in the acoustic signal x(t) is usually random, therefore, it is necessary to use multi-scale The different structural elements of construct the morphological filter to avoid serious filter output statistical shift:
[0043] The noise suppression step includes: S21, performing me...
