Abstract
In order to solve the problem of frequent oil deficiency in the oil seal cup of transformer breather in one substa-tion,this paper analyzes reasons and proposes countermeasures. Firstly,on the basis of principle of the transformer breath-ing system,it quantitatively analyzes oil level changes of the outer oil cup in the oil seal cup and summarizes the direct reason for oil deficiency is improper size of the oil seal cup. According to further decision-making analysis,it points out increase of inner diameter of the inner cup is effective and feasible. Meanwhile,it proposes to redesign size of the oil cup for processing according to calculation results. By comparing operating results of the used and the new breathers,it comes to a conclusions that oil level of the used oil seal cup dramatically reduces with increase of its running time while oil level of the newly de-signed oil seal cup keeps good which means oil mass will not reduce due to unmatched size of the cup and the problem of fre-quent oil deficiency is effectively solved.关键词
