摘要

简要介绍了在矿物油中使用金属钝化剂或钝化剂的优点。证据(从实验室测试和在使用中)表明，它们大大延长了油的热活性寿命。金属灭活化剂也可以减少变压器油的静电。除了增加油的热阻外，它们还能在较长时间内保持其电性能不变，并降低其充电倾向。尽管人们对金属灭活剂的性质和浓度以及它们与其他添加剂的相互作用提出了疑问，但这些问题都不应妨碍金属灭活剂在变压器油中的使用

On the influence of metal deactivators on some properties of transformer oils

The advantages of using metal deactivators or passivators in mineral transformer oils are briefly reviewed. The evidence (from laboratory tests and in service) has demonstrated that they considerably prolong the thermal active life of oils. Metal deactivators can also reduce the static electrification of transformers oils. In addition to increasing the thermal resistance of the oil, they also keep its electrical properties unaltered for a longer period of time and reduce its charging tendency. Although questions have been raised regarding the nature and concentration of metal deactivators as well as their interactions with other additives, none of these questions should impede the use of metal deactivators in transformer oil.<>
