         According to statistics, since 2000, has nearly a large power transformer at home and abroad (or reactor) failure occurs due to the corrosive sulfur problems in transformer oil. Many of them run 5 to 7 years of equipment, involve more than one main transformer manufacturers, the use of insulating oil by many international brand suppliers. To solve above problems, the international large power grid group (GIGRE commission) in 2005 and 2005

     xiang eagle co., LTD adopts XiangyingGC7990plus gas chromatograph analysis technology, according to IEC 62697-1:12 "unused and used insulating liquid quantitative determination method of corrosive sulfur in the first part of second dibenzyl sulfide (DBDS) quantitative determination method of the commonly used mineral insulating oil at home and abroad were reviewed and the determination of the content of DBDS. Test results show that in addition to the two DBDS content of imported oil is greater than 5 mg/kg, the remaining oil has not been detected DBDS content; All test results meet the standard IEC 62697-1:12 repetitive request. Methods concentration test range 5 ~ 600 mg/kg, detection limit of 2 mg/kg.


                      据统计,自2000年以来,国内外已有近百起大型电力变压器(或电抗器)因变压器油中的腐蚀性硫化物问题而发生故障。其中许多是运行5~7年的设备,涉及到多个主要变压器生产商,其所使用的绝缘油由多个*供应商提供。针对以上问题,国际大电网组织(GIGRE委员会)于2005年和2009
                 滕州市翔鹰分析技术有限公司采用XiangyingGC7990plus气相色谱仪,依据IEC 62697-1:2012《未使用和使用过的绝缘液中腐蚀性硫化物的定量测定方法*部分二苄基二硫醚(DBDS)的定量测定方法》对国内外常用的矿物绝缘油进行了DBDS含量的定量测定。测试结果表明,除2种进口油品的DBDS含量大于5 mg/kg外,其余油品均未检测出DBDS含量;所有测试结果均满足IEC 62697-1:2012标准的重复性要求。方法浓度测试范围5~600 mg/kg,检出限为2 mg/kg。
