Abstract

The invention provides a trace-antioxidant-containing transformer oil composition which is prepared from the following raw materials in percentage by weight: 0.04-0.08% of antioxidant, 0.003-0.007% of metal inhibitor and the balance of base oil. The trace-antioxidant-containing transformer oil composition provided by the invention can satisfy the indexes specified for T-type transformer oil in GB / T2536-2011, thereby enhancing the economical efficiency and environment friendliness of the transformer oil and satisfying the market demands.

Description

technical field [0001] The invention relates to the field of petroleum product production, in particular to a transformer oil composition containing a small amount of antioxidant. Background technique [0002] With the continuous improvement of the power industry and users' requirements for the application of transformer oil, it has become a development trend to control the content of additives in transformer oil. In the national standard GB / T2536-2011 "Unused Mineral Oil Insulating Oil for Electrical Fluid Transformers and Switches", the products have been divided into transformer oils without antioxidants (U type) and trace antioxidants ( T-type) transformer oil and antioxidant (I-type) transformer oil. For T-type transformer oil, there is still no such product that meets the above-mentioned national standards. Compared with T-type transformer oil, the existing transformer oil has too high or too low anti-oxidant, so in economical and environmental protection Sexually in...
