Izixhobo zeTransformer ezibalulekileyo zokusasazwa kwamandla

Intshayelelo:

Iitransformer zidlala indima ebalulekileyo kwiinkqubo zokusasazwa kwamandla, zinceda ekuguquleni umbane we-voltage ephezulu ube zii-voltage eziphantsi ezifanelekileyo ukusetyenziswa ekhaya nakwimizi-mveliso. Eli nqaku ligxile kwizixhobo ezibalulekileyo zetransformer eziqinisekisa ukusasazwa kwamandla ngokufanelekileyo kwaye zigubungela iinkalo ezahlukeneyo zezixhobo zetransformer, kubandakanya iinkqubo zokupholisa, izixhobo zokukhusela, iinkqubo zokubeka esweni nokulawula, kunye nezixhobo zokukhusela.

I. Iinkqubo zokupholisa:

Ukupholisa okusebenzayo kubalulekile ekugcineni ubushushu obufanelekileyo bokusebenza kweetransformer. Iinkqubo zokupholisa iitransformer zisebenzisa iindlela ezimbini: ukupholisa umoya kunye nokupholisa ulwelo.

1. Ukupholisa Umoya:

Iitransformer ezipholisiweyo ngomoya zisetyenziswa kakhulu kwiindawo ezincinci. Zixhomekeke kwi-convection yendalo okanye ukujikeleza komoya okunyanzelekileyo ukuze kususwe ubushushu. Iifeni zokupholisa zifakelwe ukuqinisekisa ukuhamba komoya okwaneleyo, okuthintela ubushushu obugqithisileyo. Iitransformer zanamhlanje ezipholisiweyo ngomoya zisebenzisa uyilo oluphambili, oluquka iiphini zokupholisa eziphuculweyo kunye neendlela zomoya ezilungiselelweyo ukuze kususwe ubushushu obungcono.

2. Ukupholisa ulwelo:

Iinkqubo zokupholisa ezingamanzi, ezibizwa ngokuba kukupholisa okufakwe kwioyile, zisetyenziswa kakhulu kwiitransformer ezinkulu. Ioyile yetransformer isebenza njengendawo yokukhusela kunye neyokupholisa. Irediyetha kunye nenkqubo yepompo zijikeleza ioyile, zisusa ubushushu kwi-transformer core kunye nee-windings. Ioyile efudumeleyo idlula kwi-radiator apho ipholiswa khona ngaphambi kokuba ibuyele kwi-transformer. Iinkqubo zokupholisa ezingamanzi eziphambili ngoku ziquka izihluzi zeoyile kunye nee-coolers ukugcina umgangatho kunye nobushushu beoyile obufanelekileyo.

II. Izixhobo zokukhusela:

Ukuqinisekisa ukusebenza ngokukhuselekileyo nangokuthembekileyo kwee-transformers, kusetyenziswa izixhobo ezininzi zokukhusela. Ezi zixhobo ziquka:

1. I-Buchholz Relay:

I-Buchholz relay sisixhobo esikhuselayo esibona iimpazamo zangaphakathi ezenzeka kwii-transformers ezizaliswe yioyile, ezifana nee-short circuits okanye ukungaphumeleli kwe-insulation. Ifakwa phakathi kwetanki ephambili kunye netanki ye-conservator. I-relay iyaziva ukuqokelelwa kwegesi ngaphakathi kwioyile kwaye ivula i-alamu okanye iqalise inkqubo yokuvala i-transformer xa kukho iimpazamo ezinkulu.

2. Ukhuseleko olugqithisileyo:

Izixhobo zokukhusela umbane ogqithisileyo ziva ukuhamba kombane okungaqhelekanga kwaye zikhusela ii-transformers kumonakalo obangelwa ngumbane ogqithisileyo. Oku kunokufezwa kusetyenziswa iifusi, ii-circuit breakers, okanye ezinye izixhobo zokukhusela. Ziphazamisa ngokuzenzekelayo umbane xa umbane udlula umda ochaziweyo, zithintela ukugqithisa nomonakalo we-transformer.

III. Iinkqubo zokubeka iliso nokulawula:

Ukuze kuphuculwe ukusebenza kwe-transformer nokwandisa ixesha layo lokuphila, kusetyenziswa iinkqubo zokubeka esweni nokulawula. Ezi nkqubo zibonelela ngolwazi lwangempela malunga nemeko ye-transformer kwaye zivumela amanyathelo okukhusela ukugcinwa kwayo.

1. Ukubeka esweni okukude:

Iinkqubo zokubeka esweni ezikude zisebenzisa ii-sensors eziphambili kunye neetekhnoloji zonxibelelwano ukubonelela ngedatha yexesha langempela kwiiparameter ezahlukeneyo ze-transformer ezifana nobushushu, amanqanaba eoyile, ukungcangcazela, kunye neemeko zomthwalo. Oku kuvumela abaqhubi ukuba bajonge impilo ye-transformer besuka kwiziko lolawulo, okuvumela ukugcinwa ngexesha elifanelekileyo kunye nokunciphisa ixesha lokungasebenzi.

2. Ulawulo lweVoltage oluZenzekelayo:

Izilawuli zevolthi ezizenzekelayo (ii-AVR) ziqinisekisa ukuphuma kwevolthi okuzinzileyo nokufunekayo. Ezi nkqubo zihlala zijonga ivolthi yokuphuma kwaye zilungisa ngokuzenzekelayo useto lwe-tap-changer yetransformer ukugcina amanqanaba evolthi afunekayo. Ii-AVR zibalulekile ekugcineni umgangatho wobonelelo lwamandla ungaguquguqukiyo kunye nokukhusela izixhobo ezinobuthathaka ekuguquguqukeni kwevolthi.

IV. Izixhobo zokuvala ubushushu:

Ukufakwa kobushushu obufanelekileyo kubalulekile ukuthintela ukuphazamiseka kombane nokuqinisekisa ukuba i-transformer ihlala ixesha elide. Izixhobo ezahlukeneyo zokufaka ubushushu zisetyenziswa ekwakheni i-transformer, kuquka:

1. Izinto zokukhusela ubushushu:

Ioyile yeminerali kunye nolwelo lwe-ester oluyilwelo zisetyenziswa kakhulu kwiitransformer zamandla. Olu lwelo lusebenza njengezinto zokuthintela umbane, i-coolant, kunye ne-arc-quenching media. Ulwelo lwe-ester oluyilwelo lunezibonelelo ezininzi, kubandakanya ukumelana nomlilo okuphezulu kunye nokuhambelana okuphuculweyo kokusingqongileyo.

2. Iphepha Lokukhusela:

Iphepha lokukhusela libekwa phakathi kweengqimba ze-transformer ukuze libonelele ngokhuseleko lombane. Iphepha elenziwe ngezinto ezifana ne-cellulose okanye ii-aramid fibers libonisa iimpawu ezibalaseleyo zombane nezoomatshini, liqinisekisa ukhuseleko oluthembekileyo lwe-transformer.

V. Isiphelo:

Izixhobo ze-transformer ezibalulekileyo zidlala indima ebalulekileyo kwiinkqubo zokusasazwa kwamandla ngokuqinisekisa ukusebenza kakuhle nangokuthembekileyo kwee-transformer. Iinkqubo zokupholisa, izixhobo zokukhusela, iinkqubo zokubeka esweni nokulawula, kunye nezixhobo zokukhusela zinegalelo ekufezekiseni ukusebenza okuphezulu, ukwandisa ubomi be-transformer, kunye nokunciphisa ixesha lokungasebenzi. Ngokuqhubeka nokuqhubela phambili ubuchwepheshe be-transformer, ezi zixhobo zibalulekileyo ziyaqhubeka nokukhula, zamkela ubuchule kwaye ziqhuba ukukhula kweenethiwekhi zokusasazwa kwamandla ezisebenzayo.
