多个变压器非放电和过热类典型缺陷案例分析

Case Analysis of Typical Defects of Non-discharge and Overheating of Multiple Transformers

变压器作为电力系统中重要的设备,在运行过程中直接决定了电力系统的安全性及可靠性。在实际生产中,变压器典型缺陷的种类比较多,然而当前国内针对变压器非放电及过热类缺陷的相关报道比较少,变压器典型缺陷的案例还有待进一步深入分析。文中对此展开探究,介绍了3种变压器典型非放电及过热类缺陷,通过变压器油检测,结合其他分析方法,寻找缺陷真实原因,旨在保障电力系统安全运行。

As an important equipment in the power system,the transformer directly determines the safety and reliability of the power system during the operation.In actual production,there are many types of typical defects of transformers.However,there are few reports on the defects of non-discharge and overheating of transformers in China.The case of typical defects of transformers needs further analysis.This article explores this and introduces the typical non-discharge and overheating defects of three kinds of transformers.Through the detection of transformer oil,combined with other analysis methods,the real reason for the defects is sought to ensure the safe operation of the power system.
