【摘要】：在現(xiàn)有風(fēng)電機(jī)組齒輪箱狀態(tài)監(jiān)測及故障診斷技術(shù)中,齒輪箱振動(dòng)狀態(tài)檢測的應(yīng)用最為廣泛,擁有較為可靠的故障診斷性能。然而,對(duì)于由磨損導(dǎo)致的齒輪箱早期故障征兆,振動(dòng)檢測往往無能為力。油液磨粒檢測是一種通過對(duì)齒輪磨損所產(chǎn)生的磨粒進(jìn)行分析從而對(duì)齒輪箱故障做出診斷的檢測手段,對(duì)此類故障的診斷較為出色。因此,兩種檢測手段可以形成互補(bǔ),提高風(fēng)電機(jī)組齒輪箱的故障檢測準(zhǔn)確率。 論文首先對(duì)風(fēng)電機(jī)組齒輪箱的基本構(gòu)成和主要故障類型進(jìn)行了簡要介紹,對(duì)現(xiàn)有的振動(dòng)狀態(tài)檢測手段和油液磨粒檢測手段進(jìn)行了研究。在此基礎(chǔ)之上,論文提出了一種新型的、基于電磁感應(yīng)原理的齒輪箱油液磨粒傳感器結(jié)構(gòu),并對(duì)其進(jìn)行了軟件仿真。隨后,論文對(duì)油液磨粒檢測裝置的信號(hào)處理電路進(jìn)行了設(shè)計(jì),并研制出了油液磨粒檢測裝置的樣機(jī)。通過測試,該新型磨粒檢測裝置的檢測靈敏度較之現(xiàn)有產(chǎn)品有了明顯的提高。 為了提高風(fēng)電機(jī)組齒輪箱的故障檢測水平,論文在對(duì)風(fēng)電機(jī)組齒輪箱典型故障及其故障檢測手段進(jìn)行了深入的研究之后,提出了一種結(jié)合了振動(dòng)狀態(tài)檢測與油液磨粒檢測的綜合檢測策略,并依據(jù)該策略進(jìn)行了風(fēng)電機(jī)組齒輪箱綜合檢測平臺(tái)的開發(fā)。
[Abstract]:In the existing wind turbine gearbox condition monitoring and fault diagnosis technology, application of gear box vibration state detection is the most widely used, has the fault diagnosis performance more reliable. However, the early fault symptom caused by wear of gear box, vibration testing is often incapable of action debris. Detection is a kind of analyzing the abrasive wear of gear produced in order to make the detection means for diagnosis of gearbox fault diagnosis, the fault of the more outstanding. Therefore, two kinds of detection methods can complement each other to improve the wind turbine gearbox fault detection accuracy.
Firstly, basic structure and main fault of gearbox of wind turbine types are briefly introduced, the vibration detection means and existing oil debris detection means are studied. On this basis, the paper puts forward a new type of gear box, the principle of electromagnetic induction oil particle sensor structure based on and has carried on the simulation software. Then, the signal processing circuit of oil liquid particle detection device for grinding paper were designed and developed a prototype oil particle detection device. Through the test, the new particle detection sensitivity detection device compared with the existing products have been significantly improved.
In order to improve the level of fault detection of gearbox of wind turbine, the paper after the means of detection of wind power units of typical faults of gear box and its fault are studied, and put forward a comprehensive detection strategy is a combination of oil detection and vibration particle detection, and on the basis of the strategy for the development of wind turbine gear box of comprehensive testing platform.
