Example Embodiment
[0089] The present application will be further described below with reference to the accompanying drawings. The following examples are for more clearly illustrative of the technical solutions of the present invention without limiting the scope of the present application.
[0090] Such as figure 1 The procedure of the distributed power transformer winding state monitoring method based on the vibration method is as follows:
[0091] Step 1, in the current sampling period, synchronize the vibration analog signal, voltage analog signal, and current analog signals of the transformer.
[0092] specifically,
[0093] In step 1, the vibration analog signal is a vibration amplitude analog signal and a vibration acceleration analog signal at different positions of the transformer fuel tank wall; the voltage analog signal and the current analog signal are voltage analog signals and current analog signals at the secondary terminal of the transformer. The vibration signal is affected by a vari...
