超高压变压器油的可吸附再生重复使用次数

Reusing Number of the Transformer Oil Treated by Adsorbent Time After Time

为了模拟某超高压变压器油吸附处理情况,对该变压器油多次重复吸附—老化—再吸附试验。考察每次油吸附后抗氧化安定性试验的指标变化趋势,得出吸附次数与抗氧化安定性参数的关系,由此评估该油可吸附再生次数证明,随着吸附次数的增多,油的抗氧化安定性能越来越好。新油和再生油的烃类组成成分的利用红外光谱法分析新油和再生油的烃类组成成分,再生油和新油成分极其相似,其分子组成结构改变不大,且含氧极性分子组分降低,小分子组分没有增加,油的组成结构更为合理,可多次吸附再生重复使用。另外吸附处理后油芳碳值CA因自然消耗而减少,可适当补加新油以提高CA。

With a view to the simulation to the transformer oil adsorbent treating practical situation of a certain nuclear power station, through the processing of multi-time adsorbing-aging-adsorbing again to the transformer oil of the nuclear power station, and the anti-oxidation invariability test after adsorbing every time, review the altering di- rection of the anti-oxidation invariability indexes after adsorbing times and times, give out the relation between antioxidation invariability indexes and times of adsorption, there by evaluate the permitted times of adsorption and regeneration, prove the multi-mime adsorbing treatments wouldn＇t led to the lowering of the anti-oxidation invariabili ty, which becomes better and better with the manifold of the adsorbing times. And then alalyze the distinguish of the hydrocarbon compound between the new oil and regenerated oil by IR, prove more it＇s very alike in component of the new oil and regenerated oil, the compound wouldn＇t change a little, and the polarity molecule containing oxygen became little, small molecule didn＇t increase, the compound frame became in reason, so the transformer oil can be adsorbed and regenerated for many times next way. In addition, the CAOf the transformer oil after treatment becomes smaller duo to natural consume, and supplement of new oil is essential for increasing the CA.
