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...
Design is a creative, complex, and iterative process. Although variety of AI models for supporting design has been developed, there little research on providing seamless flow across multiple models, as well the inspiration evolution within We present an integrated AI-based Creativity Support Tool(AI-CST) that systematically integrates contains novel Inpiration Evolver to facilitate collaboration between designers models. A between-subject sneaker-design experiment comparing our AI-CST...
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...
Frequency domain spectroscopy (FDS) is a common nondestructive test method for insulation diagnosis of transformer. Rapid and accurate testing can help improve the efficiency FDS. However, long duration conventional FDS unsatisfactory accuracy existing accelerated methods limit application conditions transformers. To tackle these problems, new named sFDS proposed, aiming to achieve rapid testing. The proposed consists two main parts goal: first, reduced by using sawtooth regression analysis....
As the main insulation material of DC cable, performance crosslinked polyethylene(XLPE) directly affects safety cable operation, and existence space charge will lead to distortion field strength. Due temperature difference between inner outer layers XLPE cables during few studies have reported effect gradient on distribution. Therefore, this paper establishes a two-dimensional model by means numerical simulation, couples temperature-electrostatic-charge multi-physical fields, simulating...
