Design of Fault Detection Experimental Teaching System for Distribution Transformer
In order to enrich the experimental teaching resources of the Electrical Equipment Online Monitoring and Fault Diagnosis course,a distribution transformer latent fault detection experimental teaching system is developed,which includes distribution transformer,vibration signal acquisition device and host computer software platform.On this basis,a new fault diagnosis method for distribution transformers is designed.The signal decomposition is realized by variational mode decomposition,fault features are extracted by multi-scale permutation entropy,and fault classification is achieved by random forest classifier.The designed experimental teaching platform can not only support conventional experimental teaching,but also allow students to design and develop applications by themselves through open design platform,which can expand their innovative thinking and improve their practical ability.
