变压器故障分析及诊断研究

Research on Transformer Fault Analysis and diagnosis

变压器是电力系统中极重要的一部分,其运转是否安全、稳定、可靠直接影响电力系统的运行状态。在变压器长期使用的过程中,发生故障在所难免,因此对于变压器潜伏性的故障要及时预测,从而确保电力系统的安全运行。文章介绍了变压器常见故障及其成因,阐述目前常用的一些诊断方法,其中重点分析了DGA和HPLC两种如今应用较广的检测诊断手段。

Transformer is a very important part of power system.Whether its operation is safe,stable and reliable will directly affect the operation state of power system.In the process of long-term operation of the transformer,it is inevitable that faults occur.Therefore,the latent faults of the transformer should be predicted in time to ensure the safe operation of the power system.This paper introduces the analysis of common transformer faults and their causes,as well as some commonly used diagnostic methods,in which DGA and HPLC are emphasized.They are widely used and common detection and diagnosis methods nowadays.
