degradation of oil impregnated paper insulation under influence of repetitive fast high voltage impulses
در طی سالهای اخیراستفاده ازمنابع انرژی تجدید پذیر در شبکه های مدرن بنا به دلایل زیست محیطی و اقتصادی به طور گسترده استفاده شده است همچون نیروگاههای بادی و خورشیدی .ولتاژتولیدی این نیروگاهها اغلب به فرم dc می باشد وادوات الکترونیک قدرت به عنوان مبدل و پل بین شکل موج dc وac استفاده می شوند.این پروسه باعث ایجاد پالسهایی برروی شکل موج خروجی می شود که می تواند وارد تجهیزات قدرت همچون ترانسفورماتور ی...
15 صفحه اولChapter 11: Mine Waste Dump
The Overburden of waste and uneconomic mineralized rock is required to be removed to mine the useful mineral resource in a surface mining operation. In this process a dump is formed by casting the waste material and dumping it in nearby area. The dump so formed is known as mine waste dump. Waste dump may be classified as internal and external dump. External dump is created outside the pit where...
متن کاملOptimization of Design Parameters and Intelligent Back-analysis of High Bench Dump Slope in Open Pit
Dump engineering is an important part in production processes of open-pit mining. In order to complete the mine production tasks smoothly, it is necessary to make the most of land possessed by the dump in an economical and reasonable way. In the paper, we use the dump of Qidashan iron mine which belongs to Anshan Iron and Steel Group as an engineering background to achieve the aim of improving ...
متن کاملA new developed model to determine waste dump site selection in open pit mines: An approach to minimize haul road construction cost
Today, during the life of an open pit mine, million tons of materials, including waste and ore, are displacing by truck fleets. In the case of a shallow ore deposit, which is located up to 300 meters to the ground surface, depending on preliminary equipment size and capacity, it will take three to five years to remove overburden and waste rocks to expose the ore body. In that period, the main w...
متن کاملSimulation of Groundwater Fluxes during Open-pit Filling and under Steady State Pit Lake Conditions
A critical component in determining post-mining pit water quality is knowledge of groundwater fluxes, both as the pit fills and after steady state conditions have been reached. Simulations of the filling of an open pit in Crescent Valley, Nevada, were made to generate inputs for pit lake chemistry predictions. The simulations show that the water table recovery is most rapid immediately after pu...
