Indima Ebalulekileyo Yobushushu Obujikayo Ekugcinweni Kwesiguquli

Intshayelelo:

Iitransformer zidlala indima ebalulekileyo ekusebenzeni kakuhle kweenkqubo zamandla ombane. Ukuthembeka kwazo nokusebenza kwazo kakuhle kuxhomekeke kwizinto ezininzi, enye yazo bubushushu bee-windings zazo. Ubushushu obujikelezayo buchaphazela ngokuthe ngqo ukusebenza kunye nobomi beetransformer, nto leyo eyenza kube yinto ebalulekileyo ekugcinweni kwazo. Eli nqaku ligxila kukubaluleka kobushushu obujikelezayo ekugcinweni kweetransformer kwaye liphonononga amaqhinga ahlukeneyo ukuqinisekisa iimeko ezifanelekileyo zokusebenza.

Ukuqonda Ubushushu Obujikayo:

1. Iindlela zokulinganisa

Ukulinganisa ngokuchanekileyo ubushushu obujijekileyo kubaluleke kakhulu ukuze kugcinwe kakuhle. Iindlela ezahlukeneyo zisetyenziswa ukujonga le parameter ibalulekileyo. Enye indlela eqhelekileyo ibandakanya ukusetyenziswa kwezixhobo zokubona ubushushu obujijekileyo (ii-RTD) ezifakwe ngaphakathi kwii-windings. Ii-RTD zibonelela ngokulinganisa ngokuchanekileyo njengoko ziguqula utshintsho lobushushu lube lutshintsho oluhambelanayo lokumelana nombane. Enye indlela ibandakanya i-infrared thermography, apho kusetyenziswa iikhamera zemifanekiso yobushushu obungenanxibelelwano ukuvavanya ukusasazwa kobushushu obujijekileyo.

2. Ukulingana kobushushu

Ukugcina ulungelelwaniso lobushushu kubalulekile ukuthintela ukunyuka okugqithisileyo kobushushu, okunokukhokelela ekonakaleni kobushushu kunye nokuncipha kwexesha lokuphila kwe-transformer. Ii-transformers zixhomekeke kwiindlela ezifanelekileyo zokupholisa, ezifana nokujikeleza kwendalo okanye ukupholisa umoya/amanzi ngokunyanzelwa, ukuze zikhuphe ubushushu obuveliswa ngexesha lokusebenza. Ukuhlolwa rhoqo kunye nohlalutyo lokuguquguquka kobushushu obujikelezayo kunceda ukuchonga naluphi na ukuphambuka kulungelelwaniso lobushushu, okuvumela ukungenelela kolondolozo ngokukhawuleza.

Impembelelo yoBushushu obujikayo kwiMpilo yeTransformer:

1. Ukuguga kwe-Insulation

Ubushushu obugqithisileyo bokujika bukhawulezisa inkqubo yokwaluphala kwe-transformer insulation. Izixhobo zokuvala, ezidla ngokwenziwa ngephepha, ibhodi yokucinezela, okanye iipolymers, zitshintsha ngokwasemzimbeni nangokweekhemikhali xa ziphantsi kobushushu obuphezulu. Ekuhambeni kwexesha, oku kunokubangela ukuqhekeka kwe-insulation, ukuncipha kwamandla e-dielectric, kunye nokwanda kobuthathaka kwiimpazamo zombane.

2. Iilahleko kunye nokusebenza kakuhle

Ukusebenza kakuhle kwee-transformers kuchaphazeleka kakhulu bubushushu obujikelezayo. Njengoko ubushushu busanda, kunjalo nokulahleka kobhedu kunye nombindi. Ukulahleka kobhedu kwenzeka kwii-winding conductors ngenxa yokufudumeza okuchaseneyo, ngelixa ukulahleka kombindi kuvela kwi-magnetization hysteresis kunye ne-eddy currents. Ukwanda kokulahleka kunciphisa ukusebenza kakuhle kwamandla kwaye kukwavelisa ubushushu obuninzi, okudala umjikelo oziqinisayo ophakamisa ngakumbi ubushushu obujikelezayo.

Amaqhinga oLondolozo:

1. Ukubeka esweni ubushushu rhoqo

Ukubeka iliso rhoqo kubushushu kubalulekile ekufumaneni utshintsho olungaqhelekanga kubushushu. Ukulinganisa rhoqo, kunye nohlalutyo lwedatha yembali, kuvumela ukuchongwa kweendlela kunye neempawu zesilumkiso kwangethuba zeengxaki ezinokubakho. Ngokungenelela ngaphambi kokuba kufikelelwe kwimida yobushushu ebalulekileyo, abasebenzi bokulungisa banokuthintela umonakalo omkhulu kunye nexesha lokungasebenzi elibizayo.

2. Uvavanyo lokuguga olushushu

Uvavanyo lokuguga olushushu lubandakanya ukubeka ii-transformer windings kumaqondo obushushu aphezulu ixesha elide. Le nkqubo yokuguga ekhawulezileyo ilinganisa iziphumo zexesha elide zamaqondo obushushu aphezulu, ivumela uvavanyo lokuwohloka kobushushu okanye ubuthathaka obunokubakho. Ngokusebenzisa amanyathelo okuthintela ngokusekelwe kwiziphumo ezifunyenweyo, ubomi be-transformer bunokwandiswa kakhulu.

3. Iindlela zoLondolozo

Ukusebenzisa indlela yokulungisa echazwe kakuhle kunceda ukuqinisekisa ukusebenza kakuhle kwe-transformer. Oku kuquka ukuhlolwa rhoqo, ukucocwa kweenkqubo zokupholisa, kunye nokutshintshwa kwezinto ezigugileyo ngexesha elifanelekileyo. Amaxesha okulungisa kufuneka ahambelane neemeko zokulayisha ze-transformer, izinto ezingqongileyo, kunye neengcebiso ezithile zomenzi.

4. Ukuphucula Ukupholisa

Ukuphucula iindlela zokupholisa ze-transformer kunokunciphisa ngempumelelo ukunyuka kwamaqondo obushushu okujijekileyo. Uphuculo olufana nokongeza iifeni zokupholisa ezongezelelweyo okanye ukuphucula imibhobho yomoya lunokuphucula ukusasazwa kobushushu. Iindlela zokupholisa ezisebenzayo, njengeenkqubo zokupholisa ioyile okanye ulwelo, nazo zingasetyenziswa, ngakumbi kwii-transformers ezinomthamo ophezulu ezisebenza kwiimeko ezinzima.

5. Ukuxilongwa Kweempazamo Nokulungiswa

Uvavanyo oluqhelekileyo kunye neenkqubo zokuxilonga zidlala indima ebalulekileyo ekuqinisekiseni impilo ye-transformer. Uhlalutyo lwegesi enyibilikisiweyo (i-DGA) lunokuchonga iimpazamo ezinokubakho ngokuvavanya uxinano lweegesi ezinyibilikisiweyo kwioyile ye-transformer. Ii-windings ezingalunganga, ezifana nee-shorted okanye ii-open circuits, zinokuchongwa ngovavanyo lombane. Ukulungiswa kunye nokutshintshwa kufuneka kwenziwe ngokukhawuleza ukuthintela umonakalo ongakumbi kunye nokugcina ukusebenza okuthembekileyo.

Isiphelo:

Ukugcinwa ngokufanelekileyo kwee-transformers kubalulekile ukuqinisekisa ukusasazwa kwamandla ombane okuqhubekayo nokufanelekileyo. Indima yobushushu bokujija ayinakugxininiswa kakhulu kule meko. Ukubeka iliso kubushushu bokujija, ukugcina ulungelelwaniso lobushushu, ukuthintela ukuguga kwe-insulation, kunye nokusebenzisa amaqhinga okugcina asebenzayo kubalulekile ekwandiseni ubomi be-transformer, ukunciphisa ixesha lokungasebenzi, kunye nokuqinisekisa umbane okhuselekileyo nothembekileyo ngakumbi.
