This paper proposes a nonlinear electromagnetic-thermal-velocity coupling model to study the insulation performance of converter transformer, in which the saddle-like electric-stress dependence is considered under compound alternating current-direct current (AC-DC) voltage situation.Firstly, the conductance of transformer oil and oil-immersed press
Copper-based polycrystalline shape memory alloys (SMAs) have limitations for many practical applications due to their low superelasticity and low ductility.In order to overcome this situation, in recent years, the production of copper-based SMAs by directional Tea Cups solidification process has attracted the interest of many researches.In this sen
