In this paper, in order to study the effect of temperature gradient on long-term reliability of high voltage direct current (HVDC) cross-linked polyethylene (XLPE) cable insulation during actual operation, an aging device under DC electrical stress companied with temperature gradient(the high temperature side is 60°C and the low temperature side is 20°C) for multi-group film specimen were designed...
The interface between accessory insulation and cable insulation suffers not only bulk electric stress along cable radial direction, but also interfacial electric stress along cable axial direction. The above orthogonal electric stress makes the interfacial space charge property complex. In this paper, cross-linked polyethylene (XLPE) and silicone rubber (SIR) were selected to form a laminate with...
The thermomechanical stress characteristics in high-power 808-nm AlGaAs/GaAs laser diode bars were investigated experimentally and theoretically using infrared thermography and finite element method in detail. The transient thermomechanical stress curves changing with total operation current were measured using infrared thermography. The results indicated that thermomechanical stress of laser diodes...
Chronic stress and neuronal vulnerability have recently been recognized as factors contributing to cognitive disorders. One way to modify neuronal vulnerability is through mediation of phosphodiesterase 2 (PDE2), an enzyme that exerts its action on cognitive processes via the control of intracellular second messengers, cGMP and, to a lesser extent, cAMP. This study explored the effects of a PDE2 inhibitor,...
