【摘要】:近年來我國大力提倡發(fā)展環(huán)保型清潔能源,風能就是其中一種。由于風力發(fā)電系統的發(fā)電機在風力不穩(wěn)定時需經常投切,導致風電變壓器易出現各種異常運行狀態(tài),因此對風電變壓器的抗沖擊、抗短路性能提出更高要求,風力發(fā)電的不穩(wěn)定性導致風電變壓器的事故率遠高于普通變壓器,對風電變壓器典型故障進行分析具有重要工程意義和應用價值,為風電變壓器設計和安全穩(wěn)定運行的打下基礎。本課題基于實際風電故障分析、設計的需求,開展“風電變壓器典型故障分析”研究。課題將針對我公司自主開發(fā)“目”字型組合式風力變壓器故障進行分析。首先從根本上分析風電變壓器事故原因,了解風電變壓器的常見故障。再次闡述色譜分析法結合各種例行試驗及其在風電變壓器故障判定的所起的作用。最后通過實際例子分析變壓器故障,采用油色譜分析檢驗,再經過直流電阻、變比、絕緣電阻等例行試驗,快速、準確、有效的判定變壓器各種故障。
[Abstract]:In recent years, China strongly advocated the development of environmentally friendly clean energy, wind energy is one of them, because the generators of wind power system often need to switch off when the wind is unstable. Wind power transformer is prone to a variety of abnormal operation state, so the wind power transformer anti-impact, anti-short-circuit performance put forward higher requirements. The instability of wind power generation results in the accident rate of wind power transformer is much higher than that of ordinary transformer. It is of great engineering significance and application value to analyze the typical fault of wind power transformer. For wind power transformer design and safe and stable operation of the foundation. This topic based on the actual wind power failure analysis, design requirements. The research of "typical fault analysis of wind power transformer" will be carried out. The paper will analyze the fault of wind power transformer based on "item" type combined wind transformer developed by our company. Firstly, the cause of wind power transformer accident will be analyzed fundamentally. To understand the common faults of wind power transformer. Thirdly, the paper expounds the function of chromatographic analysis combined with various routine tests and its role in judging the fault of wind power transformer. Finally, the transformer fault is analyzed through practical examples. Through routine tests such as DC resistance, variable ratio, insulation resistance and so on, oil chromatographic analysis is used to determine transformer faults quickly, accurately and effectively.
