Ulwelo lweTransformer lubonelela ngamandla e-dielectric kunye nokupholisa. Njengoko iqondo lobushushu le-transformer liyenyuka, olo lwelo luyakhula. Njengoko iqondo lobushushu leoli lisihla, liyacutheka. Silinganisa amanqanaba olwelo ngegeyiji yomgangatho ofakiweyo. Iya kukuxelela imeko yangoku yolwelo kunye nendlela owela ngayo ireferensi olo lwazi kunye nobushushu beoyile inokukuxelela ukuba ufuna ukonyusa i-transformer yakho ngeoyile.
Ulwelo kwi-transformer, nokuba yi-oyile okanye ulwelo olwahlukileyo, benza izinto ezimbini. Banikezela ngedielectric ukugcina umbane apho ukhoyo. Kwaye zikwabonelela ngokupholisa. I-transformer ayikho i-100% esebenzayo kwaye ukungasebenzi kubonisa njengobushushu. Kwaye ngokwenene, njengoko ubushushu be-transformer bukhuphuka, ngenxa yokuphinda ilahleko kwi-transformer, ioli iyanda. Kwaye kumalunga ne-1% kwi-10 nganye yeedigri ze-centigrade ukuba ubushushu be-transformer bunyuke. Ngoko ke ilinganiswa njani? Kulungile, ungagweba ngokudada kwigeyiji yomgangatho, inqanaba lenguqu, kunye negeyiji inalo phawu, xa inqanaba lisecaleni apha ukrozo ngenaliti ku-25 degrees centigrade. Ngoko umgangatho ophantsi uyakuba, kunjalo, ukuba iphumle ezantsi, le ingalo ingalandela inqanaba lolwelo.
Kwaye, nangona kunjalo, kwi-25 degrees centigrade, eya kuba yiqondo lokushisa eliqhelekileyo kwaye i-transformer ayinakulayishwa ngelo xesha. Nantso indlela abamisela ngayo inqanaba abaza kuqalisa ngalo. Ngoku njengokuba iqondo lobushushu linyuka kwaye olo lwelo lusanda, idada ledada liyavela, inaliti iqalisa ukuhamba.
Igeyiji yenqanaba lolwelo ijonga i-oyile okanye inqanaba lolwelo ngaphakathi kwesiguquli sakho. Ulwelo olungaphakathi kwi-padmount kunye ne-substation transformers lukhusela amajiko kwaye lupholisa i-transformer ngelixa isebenza. Kubalulekile ukuqinisekisa ukuba ulwelo luhlala lukwinqanaba elifanelekileyo kubo bonke ubomi be-transformer.
Iindibano ezi-3 eziphambili
Ukuze uchonge iintlobo ezahlukeneyo zegeji yeoli ye-transformer, kunceda ukuqonda kuqala amacandelo abo amakhulu. Igeyiji nganye ineendibano ezintathu:
INdibano yamatyala,egcina i-dial (ubuso) apho ufunda khona ubushushu, kunye nokutshintsha.
INdibano yeFlange,equka i-flange edibanisa itanki. Indibano yeflange iphinda iqulethwe ityhubhu yenkxaso, ephuma ngasemva kweflange.
INdibano yeNtonga yeNgxobhozo,ebandakanya ingalo ye-float kunye ne-float, exhaswa yindibano ye-flange.
Uhlobo lokunyuka
Kukho iintlobo ezimbini eziphambili zokuxhoma ezikhoyo kwi-OLI (izalathi zenqanaba le-oyile).
Iimpawu zenqanaba leoli ngokuthe ngqo kwiNtaba
Iimpawu zenqanaba leoli leNtaba ekude
Uninzi lwezalathi zenqanaba leoli ye-transformer zizixhobo eziNgqongileyo zeNtaba, oku kuthetha ukuba indibano yecala, indibano yeflange kunye nendibano yentonga edadayo yiyunithi enye edibeneyo. Ezi zinokuxhonywa kwicala okanye phezulu.
Iintaba ezisecaleni ze-OLIs ngokubanzi zinendibano edadayo equlathe ukudada ekupheleni kwengalo ejikelezayo. Ngelixa ii-OLLI zentaba ephezulu (izalathi zenqanaba le-oyile ezithe nkqo) zinendawo edadayo ngaphakathi kwityhubhu yenkxaso ethe nkqo.
Ii-OLIs ezikude ngokuthelekisayo ziyilelwe ukusetyenziswa apho indawo yokulinganisa ingajongwa lula ngabasebenzi, ngaloo ndlela ifuna isalathiso esahlukileyo okanye esikude. Umzekelo kwitanki yomgcini. Ngokwenza oku kuthetha ukuba iNdibano yeCase (kunye ne-dial visual) ihluke kwiNdibano ye-Float, exhunywe ngumbhobho we-capillary.
