45#变压器油的制作的要求

(1) 变压器油密度尽量小,以便于油中水分和杂质沉淀。
(1) transformer oil density as small as possible, in order to facilitate oil moisture and impurities precipitation.
(2) 粘度要适中,太大会影响对流散热,太小又会降低闪点。
(2) viscosity should be moderate, too much influence convection heat dissipation, too small will reduce flash point.
(3) 闪点应尽量高,一般不应低于136℃。
(3) flash point should be as high as possible, generally should not be lower than 136 degrees centigrade.
(4) 凝固点应尽量低。
(4) the freezing point should be as low as possible.

(5) 酸、碱、硫、灰分等杂质含量越低越好,以尽量避免它们对绝缘材料、导线、油箱等的腐蚀。
(5) the lower the content of acid, alkali, sulfur, ash and other impurities, the better to avoid their corrosion on insulating materials, wires, tanks and so on.
(6) 氧化程度不能太高。氧化程度通常用酸价表示,它指吸收1克油中的游离酸所需的氢氧化钾量(毫克)。
(6) the degree of oxidation can not be too high. The degree of oxidation usually expressed in acid value, it refers to the amount of absorption of potassium hydroxide free acid 1 grams oil required (mg).
(7) 安定度不应太低,安定度通常用酸价试验的沉淀物表示,它代表油抗老化的能力
(7) the degree of stability should not be too low, stability usually test sediment acid value, which represents the ability of anti ageing oil
