【摘要】：為深入研究變壓器絕緣油中金屬鈍化劑的消耗原因并借以制定和優(yōu)化金屬鈍化劑的添加方案,研究了不同溫度下變壓器油中金屬鈍化劑Irgamet 39消耗規(guī)律以及同一溫度下二芐基二硫(DBDS)質量分數、2,6—二叔丁基對甲酚(DBPC)質量分數、油的運行情況、紙面積、銅表面積以及銅的腐蝕情況等因素對于變壓器油中Irgamet39消耗規(guī)律的影響。采用高效液相色譜(HPLC)法檢測油中的Irgamet 39質量分數。結果表明:溫度是Irgamet 39消耗的決定因素,低溫下(≤60℃)Irgamet 39幾乎不消耗,高溫下(≥90℃)Irgamet 39消耗迅速;DBDS、運行油、絕緣紙、未腐蝕的銅和已腐蝕的銅會增加Irgamet 39的消耗;DBPC對于Irgamet 39的消耗幾乎無影響。結合Irgamet 39的作用機理可以看出,除高溫下的自身分解和與銅形成保護膜阻止腐蝕性硫對銅的腐蝕外,變壓器中的油環(huán)境和絕緣紙是Irgamet 39消耗的重要影響因素。
[Abstract]:In order to study the causes of metal passivator consumption in transformer insulation oil and to formulate and optimize the adding scheme of metal passivator, the consumption law of metal passivator Irgamet 39 in transformer oil at different temperatures and the mass fraction of dibenzyldisulfide (DBDS) at the same temperature, 2, 6-di-tert Ding Ji p-cresol (DBPC) mass fraction, oil operation and paper area were studied. The influence of copper surface area and copper corrosion on Irgamet39 consumption in transformer oil. The content of Irgamet 39 in oil was determined by high performance liquid chromatography (HPLC) (HPLC). The results show that temperature is the decisive factor for Irgamet 39 consumption, Irgamet 39 consumption at low temperature (鈮，
