Ingabe i-Transformer Yakho Ingakutshela Ukuthi Izohluleka Nini? Umhlahlandlela Wokuqapha Ku-inthanethi

Isingeniso

Iningi lempilo yabo yokusebenza, ama-transformer asebenza buthule. Izinkinga ziyavela ngaphakathi—ukushisa kuyawohloka, ukuxhumana kuyakhululeka, kwakheka izindawo ezishisayo—ngaphandle kwesixwayiso esibonakalayo. Ngesikhathi ukuvikelwa okuvamile kusebenza, umonakalo uvame ukuba usuvele wenziwe.

Izinhlelo zokuqapha eziku-inthanethi ziyakushintsha lokhu. Zinikeza ama-transformer izwi, zinikeza ukubonakala okuqhubekayo ngesimo sangaphakathi futhi zivumela amaqembu okulungisa ukuthi athathe isinyathelo ngaphambi kokuba kwenzeke ukwehluleka. Kwabachwepheshe bokuthenga, ukuqonda ukuthi lezi zinhlelo zingenzani kubalulekile ekuchazeni imishini nasekuhloleni amakhono abaphakeli.

Ingxenye Yokuqala: Kungani Kufanele Uqaphe Ngokuqhubekayo?

Ukugcinwa kwendabuko kuncike ekuhlolweni okwenziwa njalo ngezikhathi ezithile—amasampula kawoyela athathwa njalo ngekota, ukuskena kwe-thermography minyaka yonke, ukuhlolwa kukagesi njalo eminyakeni embalwa. Phakathi kwalezi zithombe, izinguquko ezibalulekile zingabonakala.

Ukuqapha ku-inthanethi kuvala lesi sikhala. Izinzwa zilandelela amapharamitha abalulekile amahora angama-24 ngosuku, izinsuku eziyi-7 ngesonto, zibona izitayela kanye nokungahambi kahle njengoba zikhula. Izifundo zibonisa ukuthi ukulungiswa okubikezelayo okuvunyelwe ukuqapha okuqhubekayo kunganciphisa ukungasebenzi kahle okungahleliwe ngamaphesenti angaphezu kwama-40 ngenkathi kunciphisa izindleko zokulungisa ngamaphesenti angaphezu kwama-30.

Icala lezomnotho liyathandeka. Uhlaka lokufunda komshini lusetshenziswa ku Isiguquli Sokusabalalisas ifinyelele ukunemba okungamaphesenti angama-94.7 ekubikezeleni ukwehluleka ezinsukwini ezingama-30 kuya kwezingama-90 kusengaphambili, okuletha imbuyiselo engamaphesenti angama-260 ekutshalweni kwemali

Ingxenye Yesibili: Ubuchwepheshe Obuyinhloko

Ukuhlaziywa Kwegesi Encibilikisiwe (i-DGA).I-DGA isalokhu iyitshe lesisekelo lokuqapha i-transformer. Lapho kuvela amaphutha angaphakathi—ukushisa ngokweqile, ukukhishwa kwengxenye, noma ukugoba—amandla akhishwayo abolisa ama-molecule kawoyela, akhiqize amagesi ahlukile. I-hydrogen ikhombisa i-corona; i-ethylene ikhombisa amaphutha okushisa; i-acetylene ikhombisa ukugoba kwamandla aphezulu.

I-DGA eku-inthanethi iqapha ukukhipha nokuhlaziya uwoyela njalo, ithola izinguquko zokuhlushwa kwegesi ngemizuzu hhayi ngezinyanga. Izinhlelo ezithuthukisiwe ezisekelwe ku-laser zithola ukuzwela okungaphansi kuka-0.1 ppm kumagesi abalulekile njenge-acetylene, okuvumela isixwayiso kusenesikhathi samaphutha akhulayo.

Ukuqapha Ukukhishwa Okungaphelele (PD).Ukukhishwa okuyingxenye kuyizinhlansi ezincane zikagesi ngaphakathi kweziphambeko zokufakwa komoya. Nakuba kungase kungabangela ukwehluleka okusheshayo, kuyawuqeda ukukhishwa komoya ngokuhamba kwesikhathi. Ukuqapha kwe-PD kuthola lokhu kukhishwa ngezindlela eziningi: Izinzwa ze-UHF zibamba ukukhishwa kwe-electromagnetic; izinzwa ze-ultrasonic zibona ukudlidliza kwe-acoustic; izinzwa ze-HFCT zilinganisa ama-pulse wamanje.

Ukuhlanganiswa kwezinzwa eziningi kuthuthukisa kakhulu ukunemba. Ukutholwa okuhlangene kukagesi nemisindo kungathola imithombo ye-PD ngaphakathi kwamasentimitha ayi-10-20, okuvumela ukulungiswa okuqondiwe.

Ukuqapha Izinga Lokushisa.Uma kukhuphuka njalo ngo-8-10°C ngaphezu kwezinga lokushisa elilinganiselwe, impilo yokuvikela ukushisa iyingxenye. Izinga lokushisa le-hotspot—hhayi uwoyela ophezulu kuphela—linquma amazinga okuguga. Izinzwa ze-fiber-optic ezifakwe kuma-windings zinikeza isilinganiso esiqondile se-hotspot, ezingaphazanyiswa yi-electromagnetic.

Ingxenye Yesithathu: Kusukela Kudatha Kuya Esinqumweni

Idatha yezinzwa eluhlaza iba yigugu kuphela uma ihunyushwa. Amapulatifomu okuqapha anamuhla ahlanganisa amapharamitha amaningi, asebenzisa ukuhlaziya ukukhiqiza ukuqonda okusebenzayo.

Ukuhlolwa Kwempilo.Izinhlelo ze-Static Asset Health Index (SAHI) zihlanganisa imiphumela ye-DGA, ukuhlolwa kukagesi, umlando wokugcinwa, kanye nedatha yokusebenza zibe yisilinganiso esisodwa sezempilo. Lokhu kwenza kube lula ukubekwa phambili kwemikhumbi yonke kanye nokungenelela okusekelwe ezimweni.

Icala langempela libonisa inani: i-transformer ibonise ukunyuka kwe-hydrogen ne-methane ezinyangeni ezintathu. Ukuhlaziywa kwe-SAHI, okuhlanganisa imiphumela yokuhlolwa kwamandla kanye nokulinganiswa komswakama, kwaphawula ingozi yokukhishwa kwengxenye kanye nokunconywa kokususwa kwesevisi. Ukuhlolwa kwangaphakathi kuqinisekisile ukuxilongwa—uwoyela ongcolile wawubangela umsebenzi we-PD. Ukufakwa esikhundleni uwoyela kuxazulule inkinga, kwavimbela lokho okungenzeka kube ukwehluleka okukhulu.

Ukuhlanganiswa Kokufunda Komshini.Izinhlelo ezithuthukisiwe zisebenzisa ukufunda komshini kudatha yomlando, zifunda amaphethini okuziphatha ajwayelekile e-transformer ngayinye. Lapho kuvela ukuphambuka, ama-algorithms abonisa ukungalingani emasontweni ngaphambi kokuba imingcele evamile iqale.

Ingxenye Yesine: Ukukhetha Uhlelo Lokuqapha

Kwabachwepheshe bokuthenga, kunezinto eziningana okufanele zicatshangelwe.

Ukumbozwa Kwepharamitha.Akuwona wonke ama-monitor alinganayo. Izinhlelo eziyisisekelo zilandelela i-DGA kuphela; amapulatifomu aphelele ahlanganisa i-DGA, i-PD, izinga lokushisa, umswakama, kanye nedatha yomthwalo. Cabanga ukuthi yimaphi amapharamitha abalulekile kuhlelo lwakho lokusebenza.

Ikhwalithi Yenzwa.Izinkomba zokusebenza ezibalulekile zifaka phakathi ububanzi bokuthola, ukunemba kokulinganisa (ngokuvamile ± amaphesenti angu-5), kanye nokuphindeka (ukuguquguquka

Izinqubo Zokuxhumana.Abaqaphi kufanele bahlangane nengqalasizinda ye-SCADA ekhona nge-Modbus, i-IEC 61850, noma ezinye izinqubo ezijwayelekile. Qinisekisa ukuthi ziyahambisana ngaphambi kokuthenga.

Amandla Okuhlaziya.Ukuhlaziywa kwedivayisi okudala ama-alamu abekwe phambili kungcono kune-data dumps eluhlaza. Funa izinhlelo ezihlinzeka ngokuhlaziywa kwethrendi, izexwayiso zesilinganiso sokushintsha, kanye nezinkomba zezempilo.

Isiphetho

Ukuqapha kwe-transformer ku-inthanethi sekukhule kusukela kubuchwepheshe obukhethekile kuya ethuluzini lokuphatha impahla elijwayelekile. I-DGA ibona izinguquko zamakhemikhali, i-PD ibona amaphutha kagesi, izinzwa zokushisa zilandelela ukucindezeleka kokushisa—ndawonye, ​​​​zinikeza ukubonakala okuphelele kwempilo ye-transformer.

Ezinhlanganweni eziphethe izimpahla ezibalulekile, umbuzo awusekho ukuthi kufanele ziqaphe yini, kodwa ukuthi ziqaphe ngokuphelele kangakanani. I-transformer ekhuluma—ngezinzwa zayo kanye nokuhlaziya—ivumela amaqembu okulungisa ukuba alalele, aqonde, futhi enze okuthile ngaphambi kokuba kwenzeke ukwehluleka.
