As an important component of point electromagnetic technology,the design and application of electrical electromagnet-ic mechanisms are crucial for improving the performance and functionality of electrical equipment.In order to further improve the reli-ability of the electromagnetic mechanism of electrical appliances,electronic information technology was used in the study,proposed the corresponding electromagnetic mechanism design scheme,and completed the optimization of the dynamic opening structure through the construction of three-phase short circuit model and arc energy model.The results indicate that the short-circuit arc power changes significantly and intensively between 0.02 and 0.04 seconds.In the short-circuit breaking experiment,the proposed dynam-ic opening distance technology corresponds to a maximum short-circuit current peak of 26.34 kA,and the minimum arcing time is on-ly 5.38 s,which is below the standard requirement of 20 ms.The above results verify that the electromagnetic mechanism of the elec-trical appliance designed has a strong breaking performance,realizes the efficient protection of the equipment,and provides a refer-ence for the research and application of electronic information technology and Electromagnetism.
