By employing imidization reaction kinetics, the molecular structure optimization of polyimide was realized, resulting in significant improvement high temperature energy storage performance.
The gelation time of Diels–Alder crosslinked HA/PEG hydrogels can be reduced to an appropriate level for cell encapsulation and survival. At the same time, DA click reaction makes gel highly resilient resistant cyclic compression loading, which biomimics native articular cartilage biomechanical functions.
The space charge effect of transformer insulating paper will distort its internal electric field, and be more prominent under extremely complex working conditions. At present, the micromechanism transport field distortion characteristics paperboard are not clear So in this article, based on bipolar carrier (BCT) model dynamic balance model, effects high temperature, aging degree, moisture content, bent degree charges accumulation studied dc voltage by numerical simulation measured data...
Debye and its modified models are widely used to explain the relaxation polarization process in dielectrics at present. However, such require prior knowledge of number branches them, so it is difficult build an equivalent circuit model that matches actual characteristics polarization. Given this issue, a new method proposed analyze by distribution time (DRT). In article, cross-linked polyethylene (XLPE) cables selected as research object first aged 160 °C for 24, 72, 144, 240, 360 h,...
A SWNTs cylindrical fiber is fabricated with diamond wire drawing dies and the SWNT ribbon-like obtained by pressure treatment. The tensile strength Young's modulus of fibers can be enhanced a maximum factor about 55.
Abstract Engineering experience shows that for transformers with long service life and serious moisture exposure, the inter‐turn paper insulation inside winding will precipitate bubbles under condition of electric field conductor heating, which endanger equipment insulation. In order to explore influence factors formation in moist insulating transformers, based on existing research content gas dissolution transformer oil, this study further considers air pressure (AP) establishes an...
The X model is a conventional tool of frequency-domain spectroscopy (FDS) technology for assessing the insulation state oil-impregnated paper (OIP) bushings. However, accuracy and applicability are questionable because it overlooked effect nonuniform thermal aging, there no models mathematical formulas that can be applied to thermal-aged OIP To solve this issue, an enhanced proposed by considering radial axial aging model's formula was deduced initially. Then, complex relative permittivity...
Abstract A slight perturbation in high-speed precision cutting could cause violent vibration of boring bars, resulting unexpected wear and failure the structures. In this paper, dynamical characteristic a bar with dynamic absorber (DVA) is investigated. Considering that nonlinear characteristics rubber ring play significant role improving capacity DVA, we proposed an equivalent linearization method for modeling hyperelastic rings based on experimental data uniaxial tensile test. The...
The moisture-dependent parameter in the aging kinetic model is inaccessible due to fluctuation of moisture during period bushing insulation. This significantly restricts adoption kinetics-based approaches for predicting transformer insulation lifespan. Given this issue, an improved proposed article, where influence interpreted by acceleration coefficient. To obtain involved parameters model, humidity determined recognizing moisture-related feature, which can be extracted from...
Frequency domain spectroscopy (FDS) is a non-destructive insulation test method that has been widely applied to the evaluation of power transformers. However, major shortcoming conventional FDS long duration. Existing studies on accelerated tests suffer from lack accuracy and are difficult apply field testing. To tackle this problem, novel (named iFDS) proposed reduce duration improve oil-paper test. Specifically, reduced firstly by signal superposition waveform prediction. Then, improved...
A two-dimensional heat transfer model for a nanocomposite phase change material (PCM) roof with an open was developed utilizing the enthalpy-porosity approach. This study numerically examined and discussed effects of sinusoidal fluctuations in external temperature on variations internal surface temperatures, fluxes, distribution four distinct roofs. These roofs included ordinary without PCM, as well three different PCM varying positions layer. The computed results indicate that presence...
