摘要: 介绍了国内外变压器油腐蚀性硫试验的几种检测方法,针对这些试验方法在适用范围、试验条件等方面进行了对比,考察目前最适合检测变压器油腐蚀性硫的方法。实验室选用性质不同的变压器油基础油和成品油,分别采用铜片法(SH/T 0304-1999、ASTM D 1275-06 B)、银片法(SH/T 0804-2007)和裹绝缘纸铜线法(IEC62535-2008)进行腐蚀性硫的检测和对比,结果表明, IEC62535-2008方法是目前适合用于检测变压器油是否存在腐蚀性硫倾向的最佳方法。

Abstract: Several test methods home and abroad for detecting corrosive sulfur in electric insulating oils were introduced and compared from the aspects of applied scope and test conditions, in order to select an optimum test method for detecting corrosive sulfur in transformer oils. Meanwhile, the corrosive sulfur in various transformer base oils and products were tested by copper sheet method (SH/T 0304-1999 and ASTM D 1275-06 B), silver strip test(SH/T 0804-2007)and copper wire wrapped with insulation paper test (IEC 62535-2008). Test results showed that IEC 62535-2008 was the most suitable method to detect the tendency of existing corrosive sulfur in transformer oils.
