Ngaba iTransformer yakho ingakuxelela ukuba iza kusilela nini? Isikhokelo sokuJonga kwi-Intanethi

Intshayelelo

Uninzi lobomi babo bokusebenza, ii-transformer zisebenza buthule. Iingxaki ziyavela ngaphakathi—ukufakwa kwe-insulation kuyawohloka, uqhagamshelo luyakhululeka, iindawo ezishushu ziyavela—ngaphandle kwesilumkiso esibonakalayo. Ngexesha lokhuseleko oluqhelekileyo lusebenza, umonakalo udla ngokuba sele wenziwe.

Iinkqubo zokubeka esweni kwi-intanethi ziyayitshintsha le nto. Zinika ii-transformers ilizwi, zibonelela ngokubonakala rhoqo kwimeko yangaphakathi kwaye zivumela amaqela olondolozo ukuba enze into ngaphambi kokuba kwenzeke ukusilela. Kwiingcali zokuthenga, ukuqonda oko ezi nkqubo zinokukwenza kubalulekile ekuchazeni izixhobo kunye nokuvavanya amandla omthengisi.

Inxalenye Yokuqala: Kutheni Usoloko Ubeka Iliso?

Ukugcinwa kwemveli kuxhomekeke ekuhlolweni rhoqo—iisampulu zeoyile ezithathwa rhoqo ngekota, ukuskena kwe-thermography minyaka le, uvavanyo lombane rhoqo emva kweminyaka embalwa. Phakathi kwezi foto, utshintsho olubalulekileyo lunokungabonwa.

Ukubeka esweni kwi-intanethi kuvala lo msantsa. Iisensa zilandelela iiparameter eziphambili iiyure ezingama-24 ngosuku, iintsuku ezisixhenxe ngeveki, zifumanisa iindlela kunye nezinto ezingaqhelekanga njengoko zikhula. Izifundo zibonisa ukuba ukugcinwa kwangaphambili okuqhutywa kukubeka esweni okuqhubekayo kunokunciphisa ukucima okungacwangciswanga ngaphezulu kwama-40 ekhulwini ngelixa kunciphisa iindleko zokulungisa ngaphezulu kwama-30 ekhulwini.

Ityala lezoqoqosho liyathandeka. Isakhelo sokufunda koomatshini sisetyenziswa Isiguquli soSasazoifikelele kwi-94.7 yeepesenti ngokuchanekileyo ekuqikeleleni ukusilela kwiintsuku ezingama-30 ukuya kwezingama-90 kwangaphambili, inika imbuyekezo ye-260 yeepesenti kutyalo-mali

Icandelo lesiBini: IiTekhnoloji eziPhambili

Uhlalutyo lweGesi enyibilikisiweyo (i-DGA).I-DGA ihlala isisiseko sokujonga i-transformer. Xa kuvela iimpazamo zangaphakathi—ubushushu obugqithisileyo, ukukhutshwa okuncinci, okanye ukugoba—amandla akhutshwayo abola iimolekyuli zeoyile, avelise iigesi ezikhethekileyo. I-hydrogen ibonisa i-corona; i-ethylene ibonisa iimpazamo zobushushu; i-acetylene ibonisa ukugoba kwamandla aphezulu.

I-DGA ekwi-intanethi ijonga ukukhupha nokuhlaziya ioyile rhoqo, ifumanisa utshintsho loxinzelelo lwegesi kwimizuzu endaweni yeenyanga. Iinkqubo ezisekwe kwi-laser eziphambili zifumana uvakalelo olungaphantsi kwe-0.1 ppm kwiigesi ezibalulekileyo ezifana ne-acetylene, nto leyo evumela isilumkiso kwangethuba malunga neempazamo ezikhulayo.

Ukubeka esweni ukukhutshwa okungeyonxalenye (PD).Ukukhupha okungaphelelanga kukukhupha umbane okuncinci ngaphakathi kweziphene zokufaka umbane. Nangona kusenokungabangeli ukungasebenzi kwangoko, kuyayitshabalalisa i-insulation ngokuhamba kwexesha. Ukubeka esweni i-PD kufumanisa oku kukhupha ngeendlela ezininzi: ii-UHF sensors zibamba ukukhutshwa kwe-electromagnetic; ii-ultrasonic sensors zibona ukungcangcazela kwe-acoustic; ii-HFCT sensors zilinganisa ii-current pulses.

Ukuhlanganiswa kwee-sensor ezininzi kuphucula kakhulu ukuchaneka. Ukufunyanwa kombane kunye ne-acoustic okudibeneyo kunokufumana imithombo ye-PD ngaphakathi kweesentimitha ezili-10-20, okuvumela ukugcinwa okujoliswe kuko.

Ukubeka esweni ubushushu.Kwiqondo lokunyuka kwe-8-10°C ngalinye ngaphezu kobushushu obulinganisiweyo, ubomi bokugquma bufikelela kwisiqingatha. Amaqondo obushushu e-hotspot—hayi ioyile ephezulu kuphela—amisela amazinga okuguga. Izinzwa ze-fiber-optic ezifakwe kwiiwindings zibonelela ngomlinganiselo we-hotspot ngqo, ezingaphazanyiswa kukuphazamiseka kwe-electromagnetic.

Icandelo Lesithathu: Ukusuka Kwidatha Ukuya Kwisigqibo

Idatha ye-sensor eluhlaza iba luncedo kuphela xa itolikwa. Amaqonga okubeka esweni anamhlanje adibanisa iiparameter ezininzi, esebenzisa uhlalutyo ukuvelisa ulwazi olusebenzisekayo.

Uhlalutyo lwezeMpilo.Iinkqubo zeStatic Asset Health Index (SAHI) zidibanisa iziphumo ze-DGA, iimvavanyo zombane, imbali yolondolozo, kunye nedatha yokusebenza zibe yinqaku elinye lempilo. Oku kwenza kube lula ukubekwa phambili kwezithuthi ngokubanzi kunye nokungenelela okusekelwe kwiimeko.

Ityala lokwenyani libonisa ixabiso: i-transformer ibonise ukunyuka kwe-hydrogen kunye ne-methane kwiinyanga ezintathu. Uhlalutyo lwe-SAHI, olubandakanya iziphumo zovavanyo lwamandla kunye nokulinganiswa komswakama, lubonise umngcipheko wokukhutshwa okuncinci kunye nokucetyiswa kokususwa kwinkonzo. Uhlolo lwangaphakathi luqinisekisile ukuxilongwa—ioyile engcolisiweyo yayibangela umsebenzi we-PD. Ukutshintshwa kweoyile kusombulule ingxaki, kwathintela oko bekuya kuba kukusilela okukhulu.

Ukuhlanganiswa kokufunda koomatshini.Iinkqubo eziphambili zisebenzisa ukufunda koomatshini kwidatha yembali, zifunda iipatheni zokuziphatha eziqhelekileyo zesiguquli ngasinye. Xa kuvela ukuphambuka, ii-algorithms zibonisa ukungaqheleki kwiiveki ngaphambi kokuba imida eqhelekileyo iqale.

Icandelo Lesine: Ukukhetha Inkqubo Yokubeka Iliso

Kwiingcali zokuthenga, kukho izinto ezininzi ekufuneka ziqwalaselwe.

Ugutyungelwa kweParamitha.Ayizizo zonke iimonitha ezilinganayo. Iinkqubo ezisisiseko zilandela i-DGA kuphela; amaqonga apheleleyo adibanisa i-DGA, i-PD, ubushushu, ukufuma, kunye nedatha yomthwalo. Cinga ukuba zeziphi iiparameter ezibalulekileyo kwisicelo sakho.

Umgangatho weSensor.Izalathisi zokusebenza eziphambili ziquka uluhlu lokufumanisa, ukuchaneka kokulinganisa (ngesiqhelo ± 5 ekhulwini), kunye nokuphindaphindwa (utshintsho

IiProtokholi zoNxibelelwano.Abahloli kufuneka badibane neziseko ze-SCADA ezikhoyo ngeModbus, IEC 61850, okanye ezinye iindlela ezisemgangathweni. Qinisekisa ukuba ziyahambelana ngaphambi kokuthenga.

Ubuchule bokuHlaziya.Uhlalutyo olukwisixhobo oluvelisa ii-alamu eziphambili lungcono kunee-raw data dumps. Khangela iinkqubo ezibonelela ngohlalutyo lwendlela, izilumkiso zesantya sotshintsho, kunye neempawu zempilo.

Isiphelo

Ukubeka esweni i-transformer kwi-intanethi kuye kwakhula ukusuka kwiteknoloji ekhethekileyo ukuya kwisixhobo solawulo lweeasethi esiqhelekileyo. I-DGA ibona utshintsho lweekhemikhali, i-PD ichonga iziphene zombane, izinzwa zobushushu zilandelela uxinzelelo lobushushu—xa zidibene, zibonelela ngokubonakala okubanzi kwimpilo ye-transformer.

Kwimibutho elawula izinto ezibalulekileyo, umbuzo awusekho kukuba kufuneka ibeke esweni na, kodwa kukuba ibeke esweni kangakanani na. I-transformer ethetha—ngezixhobo zayo zokuvavanya nokuhlaziya—ivumela amaqela olondolozo ukuba amamele, aqonde, kwaye enze ngaphambi kokuba kwenzeke ukungaphumeleli.
