Experimental Study of Electromagnetic-Temperature-Humidity Coupling in Electronic Transformers

Résumé fourni par la source

Electronic transformers usually work in high voltage, strong magnetic field, high temperature, high humidity environment, so that its anti-electromagnetic interference performance is reduced, easy to cause failure. For the electronic transformer multi-physical field coupling working conditions, a kind of electromagnetic-heat-humidity coupling experimental test platform is proposed, and according to the type of electromagnetic interference it is subjected to, the corresponding electromagnetic interference test module is developed, which mainly includes the fast transient pulse group, surge, temperature and humidity modules; it is determined that under different temperature and humidity conditions, the waveforms generated by the measured interference sources are consistent with the standard in various characteristics and are not affected by the temperature and humidity environment. temperature and humidity environment. The results show that the experimental scheme proposed in this study is reasonable and can be used for electromagnetic compatibility testing in a multi-physical field coupling environment.
