Embodiment Construction
[0066] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0067] Such as figure 1 As shown, the present invention integrates the complex relationship that the multi-position vibration signal of the transformer varies in intensity with the distance of the fault distance, constructs a GSMallat network to realize the transformer winding fault diagnosis based on the multi-source vibration signal, and its flow chart is as follows figure 1 shown.
[0068] The power transformer winding fault diagnosis method based on GSMallat-NIN-CNN network of the embodiment of the present invention, the method comprises the following steps:
[0069] Step 1. Use a multi-chann...
