Incazelo Yezingxenye Ze-Transformer

Impela, ngingakusiza ngalokho. Nasi isihloko esikhiqizwe ngokungahleliwe ngokusekelwe ezidingweni zakho:

Incazelo Yezingxenye Ze-Transformer

Ama-transformer ayizingxenye ezibalulekile ezinhlelweni zikagesi, asiza ekudluliseni nasekusabalaliseni amandla ngendlela efanele. Ukuqonda izingxenye ezahlukene ze-transformer kubalulekile ekusebenzeni kwayo kahle. Kulesi sihloko, sizohlola izingxenye ezibalulekile ze-transformer kanye nezindima zazo ekwenzeni kube lula ukudluliselwa kwamandla kagesi.

Ama-Winding Ayinhloko Nawesibili

Ama-winding ayinhloko nawesibili ayizingxenye eziyisisekelo ze-transformer. Ukugoqa okuyinhloko uhlangothi lokufaka lwe-transformer, lapho amandla kagesi enikezwa khona ekuqaleni. Kuqukethe uchungechunge lwama-coil aboshwe nxazonke kwengaphakathi le-transformer. Ukugoqa okwesibili, ngakolunye uhlangothi, uhlangothi lokukhipha lwe-transformer, lapho amandla kagesi aguquliwe enikezwa khona. Njengokugoqa okuyinhloko, ukugoqa okwesibili kuqukethe nesethi yama-coil aboshwe nxazonke kwengaphakathi. Inani lokujika kuma-winding ayinhloko nawesibili linquma isilinganiso se-voltage phakathi kwezinhlangothi zokufaka nezokukhipha ze-transformer.

Ama-winding ayinhloko nawesibili adlala indima ebalulekile ekuguqulweni kwamandla kagesi. Lapho ugesi oshintshanayo udlula ekujikijeleni okuyinhloko, udala insimu yamagnetic ehlukahlukene enkabeni ye-transformer. Le nsimu yamagnetic ehlukahlukene, yona, ikhiqiza amandla e-electromotive ekujikijeleni kwesibili, okuholela ekuguqulweni kwe-voltage kagesi kanye nogesi.

I-Transformer Core

I-transformer core ingenye ingxenye ebalulekile esisiza ukudluliselwa kwamandla kagesi. Ngokuvamile yenziwe ngezinto ze-ferromagnetic ezifana nensimbi noma insimbi, ezikwazi ukungena kahle kwamandla kagesi. I-core inikeza indlela ephansi yokungathandi ukuhamba kwamandla kagesi okukhiqizwa yi-primary winding, okuvumela ukudluliselwa kwamandla ngendlela ephumelelayo ekujikeni kwesibili.

Umklamo nokwakhiwa kwe-transformer core kubalulekile ekunciphiseni ukulahlekelwa kwamandla kanye nokwandisa ukusebenza kahle. Ama-core avame ukwakhiwa ngamashidi e-ferromagnetic aqinisiwe ukuze kuncishiswe ama-eddy currents kanye nokulahlekelwa yi-hysteresis. Lokhu kuqinisekisa ukuthi i-transformer isebenza kahle kakhulu, inciphisa ukumosheka kwamandla kanye nokukhiqizwa kokushisa.

Izinto Zokuvikela Ukushisa

Izinto zokufaka ugesi zisetshenziselwa ukuhlukanisa nokufaka ugesi izingxenye ezahlukene ze-transformer, njengezimbobo kanye nomongo. Lezi zinto zibalulekile ekuvimbeleni ukuvuza kukagesi nokuqinisekisa ukusebenza okuphephile kwe-transformer. Izinto zokufaka ugesi ezivamile ezisetshenziswa kuma-transformer zifaka iphepha, ukotini, kanye nezinto ezahlukahlukene zokwenziwa ezinikeza amandla aphezulu e-dielectric kanye nokuqina kokushisa.

Ukukhetha izinto zokufaka ugesi kubalulekile ekunqumeni ukusebenza kanye nobude besikhathi se-transformer. Ukufakwa kogesi okusezingeni eliphezulu kusiza ukunciphisa ingozi yokuphuka kukagesi futhi kuqinisekisa ukusebenza okuthembekile kwe-transformer esikhathini sayo sokuphila. Ngaphezu kwalokho, ukufakwa kogesi okufanele kunciphisa amathuba okuba neziphazamiso ezimfushane kanye nezinye izinkinga zikagesi, okuthuthukisa ukuphepha nokusebenza kahle kwe-transformer.

Thepha Isishintshi

I-tap changer iyisici esitholakala kuma-transformer amaningi esivumela ukulungiswa kwesilinganiso sokujika kwe-transformer. Lokhu kwenza ukuthi isilinganiso se-voltage phakathi kwama-windings okuqala nawesibili siguqulwe, okuhlinzeka ngokuguquguquka kokuzivumelanisa nezinguquko kunethiwekhi kagesi. Ama-tap changer avame ukusetshenziswa kuma-transformer okusabalalisa amandla ukulawula ukuphuma kwe-voltage ngokuphendula ezimweni zomthwalo ezahlukahlukene.

Kunezinhlobo ezimbili eziyinhloko zama-tap changer: ama-on-load tap changer (OLTC) kanye nama-off-circuit tap changer (OCTC). Ama-OLTC avumela ukuthi kwenziwe izinguquko ngenkathi i-transformer inikwa amandla, okwenza kube noshintsho olungenamthungo ekuphumeni kwamandla kagesi ngaphandle kokuphazamisa ukunikezwa kwamandla. Ama-OCTC, ngakolunye uhlangothi, adinga ukuthi i-transformer incishiswe amandla ngesikhathi senqubo yokuthepha. Uhlobo lwe-tap changer olusetshenziswayo luncike ezidingweni ezithile zenethiwekhi kagesi kanye nokusetshenziswa kwe-transformer.

I-Buchholz Relay

I-Buchholz relay iyithuluzi elivikelayo elivame ukufakwa kuma-transformer agcwele uwoyela ukuze kutholakale futhi kuphendulwe amaphutha angaphakathi. Isebenza ngokuqapha ukugeleza kukawoyela ngaphakathi kwe-transformer futhi ithole izimo ezingavamile njengokuba khona kwegesi noma izinguquko zengcindezi ezizumayo. Uma kutholakala ama-anomalies anjalo, i-relay iqala isignali yokuhamba ukuze inqamule i-transformer kunethiwekhi kagesi, ivimbele umonakalo owengeziwe futhi iqinisekise ukuphepha kohlelo.

I-Buchholz relay iyisici esibalulekile sokuphepha kuma-transformer agcwele uwoyela, enikeza ukutholakala kusenesikhathi kwamaphutha angaba khona futhi isize ekuvimbeleni ukwehluleka okubi kakhulu. Amandla ayo okuphendula emaphutheni okuqala kanye nokuqongelela kwegesi kuyenza ibe yingxenye ebalulekile ekuqinisekiseni ukuthembeka nokusebenza kahle kwe-transformer.

Ngamafuphi, izingxenye ze-transformer zisebenza ndawonye ukuze kube lula ukudluliselwa kwamandla kagesi ngendlela ephumelelayo. Kusukela ekujikelezweni okuyinhloko nokwesibili kuya enkabeni ye-transformer, izinto zokuvikela, izinto zokushintsha amathephu, kanye namadivayisi okuvikela njenge-Buchholz relay, ingxenye ngayinye idlala indima ebalulekile ekuqinisekiseni ukusebenza okuthembekile nokuphephile kwe-transformer. Ukuqonda lezi zingxenye kubalulekile ekugcineni ukusebenza nokuphila isikhathi eside kwama-transformer ezinhlelweni zikagesi.
