Foreword
This standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 14542-2005 "Guidelines for the maintenance of oil for the operation of transformer oil", compared with GB/T 14542-2005
The main technical changes are the following.
--- Standard name changed to "Transformer oil maintenance management guidelines";
--- modified the scope of application of the standard;
--- modified the normative reference file;
--- Added terms and definitions;
--- simplifies the contents of the sampling section;
--- modified after the new oil purification, hot oil after the oil inspection project and quality standards;
--- modified the quality of the transformer oil in the operation and testing cycle, an increase of chroma, gas, electricity tendency, corrosive sulfur, stars
Particle size, antioxidant additive content, furfural content, dibenzyl disulfide (DBDS) content and other projects;
- the interpretation of the test results is removed;
--- modified the transformer transformer oil over the limit causes and countermeasures, an increase of corrosive sulfur, particle pollution, furfural content, dibenzyl di
(DBDS) content of the limit, the possible reasons and to take countermeasures;
--- modified the oil compatibility (mixed oil) content;
--- will be running oil anti-aging measures and oil treatment section of the contents of the merger modification, the title changed to "running in the maintenance of transformer oil";
--- modified the oil storage and transportation and technical management chapter content;
- the deletion of the informative Appendix A;
--- modified the original standard information Appendix B content.
This standard uses the re-drafting method to refer to IEC 60422..2013 "Guidelines for the regulation and maintenance of mineral insulating oils in electrical equipment"
The degree of coherence of IEC 60422..2013 is non-equivalent.
This standard is proposed by the China Electricity Council.
This standard is under the jurisdiction of the National Electrification Standardization Technical Committee (SAC/TC322).
The main drafting unit of this standard. Xi'an Thermal Engineering Research Institute Co., Ltd.
This standard participates in the drafting unit. State Grid Shaanxi Electric Power Company Electric Power Research Institute, East China Electric Power Test Research Institute Co., Ltd., North China
Electric Power Research Institute limited liability company.
The main drafters of this standard. Wang Xiaowei, Feng Liping, Zhu Hongmei, Peng Wei, Wang Yinggao, Li Yefeng.
This standard replaced the previous version of the standard release.
