Ukuqinisekisa uKhuseleko: Ukubaluleka kweZibonakaliso zoBushushu obujikelezayo kwiiTransformers

Intshayelelo

Iitransformer zizixhobo ezibalulekileyo kwiinkqubo zokusasazwa kwamandla, ezibonelela ngotshintsho lwe-voltage olufunekayo ukuqinisekisa ukuhanjiswa kwamandla ombane ngokufanelekileyo. Nangona kunjalo, ukusebenza okuthembekileyo kweetransformer kuxhomekeke kakhulu ekugcineni ubushushu bazo obufanelekileyo. Ukufudumala okugqithisileyo kunokukhokelela ekuwohlokeni kobushushu, ukunciphisa ixesha lokuphila, kwaye kunokubeka nomngcipheko womlilo okanye ukuqhuma. Ukunciphisa le mingcipheko, izalathisi zobushushu ezijikelezayo (ii-WTI) zidlala indima ebalulekileyo ekujongeni nasekuqinisekiseni ukhuseleko lweetransformer. Ngokuhlala zilinganisa ubushushu bee-transformer windings, ii-WTI zibonelela ngolwazi olubalulekileyo lokugcinwa kokuthintela kunye nokuchongwa kwangethuba kwempazamo. Eli nqaku lihlola ukubaluleka kwezalathisi zobushushu ezijikelezayo kwiitransformer kunye negalelo lazo ekuqinisekiseni imisebenzi ekhuselekileyo nethembekileyo.

Indima Yezibonisi Zobushushu Ezijikelezayo

Ukuqinisekisa Iimeko Zokusebenza Ezifanelekileyo

Izalathisi zobushushu ezijikelezayo zisebenza njengesixhobo esibalulekileyo sokujonga ubushushu bee-windings ze-transformers, zibonelela ngolwazi olubalulekileyo malunga neemeko zazo zokusebenza zangoku. Ngokujonga rhoqo amanqanaba obushushu, ii-WTI zivumela abaqhubi ukuba bahlole ukuba ngaba ii-transformers zisebenza ngaphakathi kwemida yazo yobushushu echaziweyo. Oku kubalulekile njengoko i-transformer nganye yenzelwe ukusebenza ngokufanelekileyo ngaphakathi koluhlu oluthile lobushushu, ngaphaya koko ukusebenza kwayo kunye nokuthembeka kwayo kunokuphazamiseka. Ii-WTI zivumela ukujonga ngexesha langempela, ukuqinisekisa ukuba ubushushu obujikelezayo buhlala ngaphakathi koluhlu oluvumelekileyo.

Ngokuhlala ejonga amanqanaba obushushu, ii-WTI zivumela abaqhubi ukuba babone naluphi na ukunyuka kobushushu okungaqhelekanga, okubonisa isiphene esinokubakho okanye icandelo elingasebenzi kakuhle ngaphakathi kwi-transformer. Ukufunyanwa ngokukhawuleza kweengxaki ezinjalo kubalulekile ukuthintela nawuphi na umonakalo okanye ukusilela okukhulu. Ukufunyanwa kwangethuba kwesiphako kunceda ukunciphisa iingozi kwaye kuvumela amanyathelo afanelekileyo okulungisa imeko, ukunciphisa ixesha lokungasebenzi kunye neendleko ezinxulumene noko.

Ukuthintela ukubola kobushushu

Ukufakwa kwe-insulation yinxalenye ebalulekileyo yee-transformers, ukuqinisekisa ukwahlukaniswa kombane kunye nokuthintela ukuvuza kwamandla. Nangona kunjalo, ukufudumeza okuqhubekayo nokugqithisileyo kunokukhokelela ekonakaleni kokufakwa kwe-insulation, okubeka yonke i-transformer emngciphekweni. Ngoncedo lwee-WTIs, abaqhubi banokujonga ngokusondeleyo ubushushu obujikelezayo kwaye bachonge naluphi na ukunyuka okungaqhelekanga kobushushu okunokubangela umonakalo wokufakwa kwe-insulation. Ngokubona ezi zinto zingaqhelekanga kwangethuba, amanyathelo afanelekileyo anokuthathwa ukuthintela ukonakala kokufakwa kwe-insulation kunye nokwandisa ubomi be-transformer.

Ukuthintela uMlilo

Enye yezona ngozi zibalulekileyo ezinxulumene nokushisa kakhulu kwee-transformers kukwenzeka komlilo. Ukupholisa okunganelanga, imithwalo yamandla amaninzi, okanye iimpazamo ngaphakathi kwe-transformer zinokubangela ukunyuka okukhulu kobushushu, okukhokelela ekuqhekekeni kobushushu kunye nokutsha kwezinto ezinokutsha. Ngokujonga rhoqo ubushushu obujikelezayo kusetyenziswa ii-WTIs, iimpawu zesilumkiso zasekuqaleni zinokufunyanwa, zinike abaqhubi ixesha elibalulekileyo lokungenelela kunye nokuthintela iingozi zomlilo ezinokubakho. Xa kuchongwa amazinga obushushu angaqhelekanga, abasebenzi bokulungisa banokuphanda unobangela kwaye bathathe amanyathelo afanelekileyo ngaphambi kokuba imeko ibe ngumlilo okanye ukuqhuma.

Iintlobo zeZibonakaliso zoBushushu obujikelezayo

Izixhobo zokuGuqula ubushushu obuchaseneyo (iiRTD)

IiResistance Temperature Detectors (RTDs) zezinye zezona ntlobo zisetyenziswa kakhulu zezibonakaliso zobushushu obujikelezayo. Ezi zixhobo zixhomekeke kumgaqo wokuba ukumelana kombane kweentsimbi kuyatshintsha ngobushushu. IiRTD zihlala zakhiwa kusetyenziswa izixhobo ezifana neplatinum, nickel, okanye ithusi, ezibonisa utshintsho oluqikelelweyo noluthe tye ekumelaneni nokutshintsha kobushushu. Ngokulinganisa ukumelana kweRTD, ubushushu obuhambelanayo bunokufunyanwa ngokuchanekileyo.

Ii-thermocouples

Ii-thermocouples lolunye uhlobo olusetyenziswa kakhulu lwezixhobo zokuva ubushushu ezisetyenziswa kwizalathisi zobushushu ezijikelezayo. Ezi zixhobo zenziwe ngeentsimbi ezimbini ezahlukeneyo ezidityaniswe kwelinye icala, ezaziwa ngokuba yi-hot junction. Xa kukho i-gradient yobushushu, amandla e-electromotive (EMF) aveliswa ngokomlinganiselo wobushushu. Ngokulinganisa le EMF, ubushushu bokujikeleza bunokufunyanwa. Ii-thermocouples zaziwa ngokuqina kwazo, uluhlu olubanzi lokulinganisa ubushushu, kunye nokukwazi ukusebenza kakuhle kwiindawo ezinzima, okwenza zifaneleke ukusetyenziswa kwe-transformer.

Ukuchasana notshintsho kwiimeko ezingqongileyo

Kwiindawo eziguqulayo, izinto ezinje ngokufuma, ukungcangcazela, kunye nokuphazamiseka kombane zinokuchaphazela ukuchaneka kunye nokuthembeka kwezalathisi zobushushu ezijikelezayo. Ke ngoko, kufuneka kunikwe ingqwalasela ekhethekileyo ekukhetheni nasekuyilweni kwee-WTI ukuqinisekisa ukuba ziyamelana neemeko ezinjalo ezimbi. Abavelisi badla ngokusebenzisa iindlela eziqinileyo zokuhlala, ukhuselo, kunye neendlela eziphambili zokulinganisa ukunciphisa impembelelo yezinto zangaphandle ekusebenzeni kwee-WTI. Ukongeza, ukulinganisa rhoqo kunye nokuhlolwa kokugcinwa kuyimfuneko ukuqinisekisa ukufundwa kobushushu okuchanekileyo kunye nokusebenza okuthembekileyo kwezalathisi.

Ukufakwa kunye nokuhlanganiswa kweZibonakaliso zoBushushu obujikelezayo

Ukubekwa ngokuchanekileyo

Ukulinganiswa ngokuchanekileyo kobushushu obujikelezayo kuxhomekeke kakhulu ekubekweni ngokufanelekileyo kwee-sensors zobushushu. Ukuqinisekisa ukufundwa kobushushu okuchanekileyo, ii-sensors zobushushu kufuneka zibekwe ngobuchule kwiindawo ezibalulekileyo ngaphakathi kwi-transformer. Oku kuquka ukubeka ii-sensors kufutshane neendawo ezinobushushu obuphezulu okanye iindawo ezinokuba neendawo ezinokuba ne-hotspots. Ngokubeka ii-sensors kwezi ndawo, abaqhubi banokubona i-gradients yobushushu engaqhelekanga baze bathathe amanyathelo afanelekileyo ukuthintela naziphi na iimpazamo okanye ukungaphumeleli okuzayo.

Ukuhlanganiswa neeNkqubo zoKubeka esweni

Ukuphucula ukusebenza kakuhle kwezalathisi zobushushu ezijikelezayo, ukuhlanganiswa neenkqubo zokubeka esweni nokulawula eziphambili kubalulekile. Iinkqubo zokubeka esweni zanamhlanje zinokuqokelela idatha kwii-WTI ezahlukeneyo ezifakwe kwii-transformers ezahlukeneyo kwaye zibonelele ngolwazi olupheleleyo malunga nempilo iyonke kunye nokusebenza kwee-transformers. Ukuhlanganiswa neenkqubo zolawulo lolawulo kunye nokufunyanwa kwedatha (SCADA) kwenza kube lula ukubeka esweni ngexesha langempela, ukuloga idatha, kunye nolawulo oluphakathi lwee-transformers, ukuphucula ukusebenza kakuhle kunye nokuqinisekisa impendulo ekhawulezileyo kuyo nayiphi na ukunyuka kobushushu okungaqhelekanga okufunyenwe yi-WTIs.

Isiphelo
