Problems connected with the occurence of corrosive sulphur in transformer oils
Języki publikacji
Abstrakty
Przedstawiono przyczyny występowania korozyjnych związków siarki we współcześnie produkowanych olejach elektroizolacyjnych oraz mechanizm i czynniki sprzyjające ryzyku uszkodzeń transformatorów spowodowanych osadami siarczku miedzi. Omówiono metody badań korozyjności i projekt nowej normy IEC, przykładowe wyniki badań olejów świeżych i eksploatowanych, sposoby przeciwdziałania zagrożeniu, ich zalety i wady.
Presented are causes of corrosive sulphur compounds occurence in present-day produced electroinsulation oils as well as the mechanism and factors conducing to the risk of transformer damages caused by deposits of copper sulfide. Discussed are methods of corrosion research, project of a new IEC standard, exemplary results of tests carried on fresh and used oils, advantages and disadvantages of methods to counteract hazards.
