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 اولThermal Degradation of Polymers at High Temperatures
Work on thermal ~egradation of poly mers has prev iously been carried out aL lempC'mt ures up to about 500 G. In the present work the range has been extend cd to 850 0 C. Polystyrene was pyrolyzed in a vacuum and also in helium at atmos pheric pressure at 3620 and at 850 0 C. Analysis of t he volatile products indicates that higher temperatures a nd hi~her. pressures cause a greater fragmen tat...
متن کاملconsequence analysis of the leakage, ignition and explosion during high pressure sour gas injection process to the oil reservoir
there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...
Thermal Degradation
When wood is exposed to elevated temperatures, changes can occur in its chemical structure that affect its performance. The extent of the changes depends on the temperature level and the length of time under exposure conditions. The changes in chemical structure may be manifested only as reduced strength, and hydroscopic water and volatile oil weight loss. In contrast, very drastic chemical cha...
