Nano Material

This project is funded by the National Key R&D Program of China and focuses on the electron transport and energy transfer modeling to untether the electrical breakdown and flashover mechanism of dielectrics.

This project investigated the coupling impact of space charge accumulation, transient arc microparticle bombardment, metal particle deposition on the flashover property of fracture insulating system in the process of dc arc switching, and revealed its influence regularity and failure mechanism. The study figured out the methods to suppress the space charge accumulation and metal particle deposition in the fracture insulating system and proposed approaches to resist electrical breakdown damage and aging based on nanocomposite modification tech.

High energy density issue is essential for both electrical transportation and the power transmission. This project primarily focuses on the energy density promotion of the power capacitor to better adapt to the need of high voltage direct transmission.
