110kV变电站主变故障的诊断与处理分析

Fault Diagnosis and Treatment of Main Transformers in 110k V Substation

随着我国城市化建设步伐的不断加快,电网应用质量开始引起诸多领域的关注,尤其是110kv变电站,直接承接了单位社会成员生活、工业、公共设施等供电任务。在变电站之中,变压器主导地位异常深刻,只有将其内部隐藏的故障问题调试完毕,才能进一步维持城市电网运营的安全可靠地位,为今后居民生活质量大幅度提升提供了坚实保障。本文从变电站主要变压器(以下简称"主变")的保护说起,简要介绍了几种较为常见的变电站主变故障、成因及故障处理方法,并结合某变电站运行过程中发生的一起主变故障深入解析故障处理思路,以供同行参考。

With the accelerated pace of urbanization in China, grid application quality has began to attract more attention in many fields, especially in 110 k V substation, which directly undertakes the power supply task of life, industry, public facilities of social unit members. In the substation, the transformer＇s dominant position is very profound, so only the faults hidden in its internal are debugged, safe and reliable position of the city power grid operation can be further maintained, in order to provide a solid guarantee for greatly enhancing the life quality of residents. This paper starts from the main transformer substation protection, briefly introduces several common faults of main transformers, causes and troubleshooting methods, and combines with the main transformer fault occurring in the process of a substation operation to in-depth analyze the fault handling methods, so as to provide references for peers.
