Itholakala enhliziyweni yesitshalo samandla kagesi, phakathi kwamandla amakhulu e-kinetic ama-turbine kanye nobubanzi obukhulu begridi yokudlulisa, isebenzisa ubuchwepheshe obubalulekile: i-power transformer. Ngokuvamile inganakwa, lesi sivikelo esithule siyisixhumanisi esibalulekile esenza ukulethwa kwamandla kagesi avuselelekayo kude kube nokwenzeka.
Ukusuka Emanzini Kuya Engcingweni: Isidingo Sokuguqulwa
Inqubo eyisisekelo yamandla kagesi asebenzisa amanzi ilula kakhulu. Amandla angase abe khona avela emanzini agciniwe aguqulwa abe amandla omshini yi-turbine, bese ijikeleza i-generator ukuze ikhiqize ugesi. Kodwa-ke, ugesi we-alternating current (AC) okhiqizwa yile mishini uvame ukuvela ezingeni le-voltage eliphakathi, njenge-11 kV, 13.8 kV, noma i-24 kV. Nakuba kufanelekile emabangeni amafushane, ukudlulisa amandla amaningi kule voltage akusebenzanga kahle kakhulu ezindaweni ezinde.
Yilapho i-transformer yenza khona indima yayo ebalulekile. Iyidivayisi kagesi engaguquki esebenzisa isimiso sokungeniswa kwe-electromagnetic ukwandisa, noma "ukuphakamisa," i-voltage yokudlulisa. Ngokukhuphula i-voltage iye emazingeni aphezulu kakhulu—ngokuvamile i-138 kV, 230 kV, 500 kV, noma ngaphezulu—i-transformer yehlisa kakhulu ugesi kagesi ngenani elithile lamandla.
Le nhlanganisela yamandla aphezulu, aphansi iyisihluthulelo sokudluliselwa kwamandla okuphumelelayo. Ngokomthetho kaJoule, ukulahlekelwa kwamandla ku-conductor kuhambelana nesikwele samandla kagesi (P_loss = I²R). Ngakho-ke, ngokunciphisa amandla kagesi, i-transformer inciphisa ukulahlekelwa okunamandla emigqeni yokudlulisela, iqinisekisa ukuthi amandla ahlanzekile akhiqizwa yi-waterfall ahamba amakhulu amakhilomitha ngempumelelo enkulu.
Ukwakheka Komshini Wokuguqula Isitshalo Sikagesi Ngamanzi
Ama-transformer ezitshalweni zikagesi wamanzi awawona amayunithi avamile; ayimishini eqinile, enamandla amakhulu eyenzelwe ukuthembeka.
I-Core kanye ne-Windings: Enhliziyweni yayo (ngokoqobo), yakhiwe i-core yensimbi e-laminated kanye namasethi amabili e-copper noma i-aluminium windings: i-primary (uhlangothi olune-voltage ephansi oluxhunywe ku-generator) kanye ne-secondary (uhlangothi olune-voltage ephezulu oluxhunywe kugridi).
Uhlelo Lokupholisa: Ukuphatha amandla amaningi kudala ukushisa okukhulu. Ama-transformer ezitshalo zamanzi asebenzisa izinhlelo zokupholisa eziyinkimbinkimbi, ngokuvamile asebenzisa uwoyela hhayi nje kuphela ekushiseni kodwa futhi nasekushabalaliseni ukushisa. Izinhlelo ezivamile zifaka:
I-ONAN (Amafutha Omoya Wemvelo): Ithembele ekuhlanganisweni kwemvelo kwamafutha nomoya.
I-ONAF (Amafutha Aphoqelekile Umoya): Isebenzisa amafeni ukuphoqa umoya phezu kwama-radiator okupholisa.
I-OFAF (i-Oil Forced Air Forced): Isebenzisa amaphampu ukujikeleza uwoyela kanye namafeni ukuze iwupholise, isetshenziselwa amazinga aphezulu kakhulu wamandla.
Ithangi Lomlondolozi: Ingxenye ebalulekile yithangi lomlondolozi, elivumela ukunwebeka nokufinyela kukawoyela wokuvikela njengoba i-transformer ishisa futhi iphola ngesikhathi sokusebenza.
Izinhlelo Zokuvikela: Lawa ma-transformer afakwe isethi yamadivayisi okuvikela, okuhlanganisa ama-relay e-Buchholz athola amaphutha angaphakathi, amadivayisi okusiza ekucindezelweni, kanye nezinhlelo zokuqapha eziyinkimbinkimbi zokushisa, ukuhlaziywa kwegesi, kanye nokukhishwa kwengxenye.
Izinselele Eziyingqayizivele Nokucatshangelwa Kokuklama
Indawo yesitshalo sikagesi wamanzi inikeza izinselele ezithile zokuklama nokubeka i-transformer.
Indawo: Zingatholakala ngaphakathi, ngaphandle, noma ngisho nasemagodini angaphansi komhlaba. Amayunithi angaphandle kumele akhiwe ukuze amelane nezimo zezulu ezinzima, kuyilapho amayunithi angaphakathi edinga izinhlelo zokucima umlilo ezithuthukisiwe kanye nohlelo lokungenisa umoya.
Ezokuthutha: Njengoba zinobukhulu nesisindo esikhulu, ukuthutha lawa ma-transformer ezindaweni zamadamu ezikude, ezinezintaba kuyisenzo esikhulu kakhulu sokuhamba.
Ukweqiwa kanye Nokuthembeka: Njengephuzu elilodwa lokwehluleka, ukuthembeka kwe-transformer ye-generator step-up (GSU) kubaluleke kakhulu. Izitshalo eziningi zinezinhlelo ze-bypass eziyinkimbinkimbi noma ngisho ne-transformer eyengeziwe endaweni ukuze kuncishiswe isikhathi sokungasebenzi ngesikhathi sokulungiswa noma ukwehluleka.
Ngale Kwejenereyitha: Amanye Ama-Transformer Esitshalweni
Nakuba i-transformer eyinhloko ekhuphukayo iyinkanyezi yombukiso, isitshalo sikagesi sithembele emndenini wonke wama-transformer:
Ama-Transformer Esevisi Yesiteshi: Lawa “ma-transformer asizayo” ehlisa i-voltage ephezulu aye emazingeni aphansi (isb., 480V) ukuze anike amandla izinhlelo ezibalulekile zesitshalo—ukukhanyisa, izinhlelo zokulawula, amaphampu okupholisa, kanye nama-motor esango.
Ama-Transformer Asizayo Eyunithi: Lawa axhunywe ngqo ekuphumeni kwejeneretha futhi ahlinzeka ngamandla ikakhulukazi ezinhlelweni ezisizayo zaleyo yunithi ekhiqizayo.
Isiphetho
I-hydroelectric transformer iwumsebenzi wobuciko wobunjiniyela kagesi, ingxenye ebalulekile neqinile esebenza njengesango phakathi kokukhiqizwa nokusetshenziswa. Ngaphandle kwekhono layo lokukhulisa amandla kagesi ngempumelelo, amandla ahlanzekile, avuselelekayo asetshenziswa emifuleni nasemadamini abengeke afinyelele emadolobheni nasezimbonini ezithembele kuwo. Ima njengobufakazi obuthule nobunamandla bobuhlakani obudingekayo ukuze kunikezwe amandla umhlaba wethu wanamuhla ngendlela eqhubekayo.
