Numerical Analysis of a Continuous Vulcanization Line to Enhance CH4 Reduction in XLPE-Insulated Cables.

摘要: Herein, we apply a computational diffusion model based on Fick’s law to study the manner in which cable production line and its operating conditions can be enhanced effectively reduce CH4 concentration cables insulated with cross-linked polyethylene (XLPE). Thus, quantitatively analyze effect of conductor temperature, curing tube temperature distribution, transition zone length, online relaxation generation transport during 132 kV an insulation thickness 16.3 mm. Results show that is initially controlled by preheater, distribution considerably affect because their direct impact temperature. The simulation results 2.7% less remaining when preheater set at 160 °C compared no used. To consider three patterns across tube: constant linear incremental decremental amount was linearly increased from 300 400 1.6% 3.7% lower than cases 350 decrease °C, respectively. In addition, simulations demonstrate removal up 9.7% applying elongated zone, extends residence time for decelerates Finally, addition section high this facilitates 2.2%, becomes greater low speeds.
