环烷基变压器油的氧化安定性及应用分析

发布时间2018-08-17  来源:http://www.wunqdctk.com

氧化安定性是变压器油的重要性能。
Oxidation stability is an important property of transformer oil.
为了提高变压器油油品的氧化安定性,通常加入氧化抑制剂。但氧化抑制剂的加入,也会影响到变压器油的耐电压和介损性能,因此抑制剂的加入量受到了严格限制。
In order to improve the oxidation stability of transformer oil and oil, oxidation inhibitors are usually added. However, the addition of oxidation inhibitors will also affect the voltage resistance and dielectric loss performance of transformer oil, so the amount of inhibitors is strictly limited.
减少抑制剂加量或不加抑制剂,是变压器油的发展趋势。尤其是超高压变压器油,倾向于不含抑制剂。对于Ⅰ类和Ⅱ类变压器油,基础油就要求具有良好的氧化安定性,只有环烷基油经过适当处理或加入适量的芳烃类基础油,就可达到氧化安定性的要求,同时还可以满足超高压变压器油析气性的要求。

Reducing the amount of inhibitor or no inhibitor is the development trend of transformer oil. Especially the UHV Transformer oil tends to contain no inhibitor. For type I and type II transformer oils, the base oils are required to have good oxidation stability. Only the naphthenic alkyl oils can be treated properly or the aromatics base oils can meet the requirements of oxidation stability. At the same time, it can also meet the requirements of gas evolution of ultra-high voltage transformer oils.
使用环烷基基础油调制变压器油,有着其它种类基础油没有的优势。国内外大型变压器制造商,都指定用环烷基油生产的变压器油。
The use of naphthenic base oil to modulate transformer oil has the advantage of other types of base oils. Large transformer manufacturers at home and abroad specify transformer oils produced from naphthenic base oils.
变压器油的主要作用是绝缘和冷却散热。而由于环烷基油粘度指数低,在变压器温度升高时,粘度迅速下降而加快循环速度,从而提高了散热的效果。
The main function of transformer oil is insulation and cooling. Because of the low viscosity index of naphthenic alkyl oil, when the temperature of transformer rises, the viscosity decreases rapidly and the circulation speed is accelerated, thus improving the heat dissipation effect.
以环烷基为原料油的变压器油凝固点低,按上述工艺制备的基础油料,凝固点通常在-30℃以下,可直接生产25号变压器油产品,稍加处理就可以生产45号变压器油产品。而其它种类基础油需要脱蜡、甚至深度脱蜡才能满足要求。
Transformer oil with naphthenic alkyl as raw material has low solidification point. The solidification point of the base oil prepared by the above process is usually below - 30 C. It can directly produce No. 25 transformer oil products. 45 transformer oil products can be produced with a little treatment. Other types of base oils require dewaxing and even deep dewaxing to meet the requirements.
由此可见,用环烷基油生产低凝点变压器油或其它低凝点油品有着一定的优势。
It can be seen that naphthenic alkyl oil has certain advantages in producing low pour point transformer oil or other low pour point oils.
