Statistics and Analyses of Accidents and Defects for 110(66) kV and the Above Transformer in 2005

文章统计分析了2005年度国家电网公司系统110(66)kV及以上电压等级互感器的事故与缺陷的情况。对2005年度互感器的在运情况、事故原因及缺陷分析、在运互感器管理中存在的问题等方面进行了统计和分析。通过对互感器事故与缺陷的统计分析,发现制造质量不良是造成互感器损坏的主要原因之一。文章对防止和减少互感器损坏事故与缺陷提出了一些措施建议,如加强设备入网管理、建立和完善在运互感器和供应商的评估体系等。

Statistics and analyses of accidents and defects for 110（66） kV and the above transformer ha SGCC system ha 2005. The operation conditions, accident reasons, problems in management for transformer in 2005 were analyzed. Through the statistical analysis for transformer accidents and defects, it is discovered that bad quality of product is the one of major reason for transformer damages. The paper presents some measures and suggestions for preventing and reducing the accidents and defects of transformer damages, such as strengthening equipment management, establishing and improving the assessment system for the transformer in operation and the supplier of transformer.
