Kula macandelo alandelayo, siza kuchaza amanyathelo abandakanyekayo ekubaleni ubungakanani be-transformer, sikunike ukuqonda okucacileyo nokupheleleyo kwale nkalo ibalulekileyo yoyilo lombane.

Inyathelo 1: Chonga iimfuno zomthwalo

Inyathelo lokuqala lokulinganisa ubungakanani be-transformer kukufumanisa ngokuchanekileyo iimfuno zomthwalo wenkqubo yombane eza kuyibonelela. Oku kuquka ukubala imfuno yamandla iyonke yomthwalo, echazwa ngee-kilowatts (kW) okanye ii-volt-amperes (VA), kunye nokuqwalasela uhlobo lomthwalo, nokuba uyathintela, uyabangela umbane, okanye unamandla. Ngokuqonda iimfuno zomthwalo, unokuqinisekisa ukuba i-transformer iyakwazi ukubonelela ngamandla afunekayo ngaphandle kokuxinwa kakhulu, ngelixa ikwavumela ukwanda kwenkqubo yombane kwixesha elizayo.

Ukuze umisele iimfuno zomthwalo, kuya kufuneka uqokelele ulwazi olufanelekileyo malunga nezixhobo eziqhagamshelweyo, kubandakanya amandla azo alinganisiweyo, ukutsalwa kwamandla, kunye ne-power factor.

Ngokuhlalutya ngononophelo iimfuno zomthwalo, unokuqinisekisa ukuba i-transformer inobungakanani obufanelekileyo ukuze ihlangabezane neemfuno zenkqubo yombane eza kuyisebenzela.

Inyathelo lesi-2: Bala i-Full-Load Secondary Current

Nje ukuba iimfuno zomthwalo zichongiwe, inyathelo elilandelayo kukubala umbane wesibini womthwalo opheleleyo we-transformer. Oku kuquka ukusebenzisa le fomyula:

I = (S × 1000) / (V × √3)

Apho:

I = Umthwalo opheleleyo wamandla wesibini kwii-ampere (A)

S = Uvavanyo lwamandla olubonakalayo lwe-transformer kwi-kilovolt-amperes (kVA)

V = I-voltage yesibini kwii-volts (V)

Ngokubala umbane wesibini ogcweleyo, ungaqinisekisa ukuba i-transformer iyakwazi ukubonelela ngombane ofunekayo kumthwalo ngaphandle kokudlula umthamo wayo olinganiselweyo. Eli nyathelo libalulekile ekuthinteleni ukugqithiswa kakhulu nokuqinisekisa ukusebenza ngokukhuselekileyo nangokuthembekileyo kwe-transformer.

Inyathelo lesi-3: Chonga uMgaqo weVoltage

Enye into ebalulekileyo ekufuneka iqwalaselwe ngobukhulu be-transformer kukulawulwa kwe-voltage, okubhekiselele kubuchule be-transformer bokugcina i-voltage ephumayo ingaguqukiyo phantsi kweemeko ezahlukeneyo zomthwalo. Umgangatho wokulawulwa kwe-voltage uchazwa njengepesenti kwaye luphawu lokusebenza kwe-transformer ngokubhekiselele ekugcineni uzinzo lwe-voltage.

Ulawulo lwe-voltage ye-transformer luphenjelelwa zizinto ezahlukeneyo, kubandakanya uyilo lwe-transformer, uhlobo lomthwalo, kunye nomgangatho wesekethe yokulawula i-voltage. Ukuze ufumane ulawulo lwe-voltage ye-transformer, kuya kufuneka ubale ipesenti yotshintsho kwi-voltage yokuphuma ukusuka kwiimeko zokungabikho komthwalo ukuya kwiimeko zomthwalo opheleleyo, usebenzisa le fomyula:

%VR = (VNL - VFL) / VFL × 100

Apho:

%VR = Ulawulo lwepesenti yevolthi

I-VNL = I-voltage yesibini engenamthwalo

I-VFL = I-voltage yesibini yomthwalo opheleleyo

Ngokuqonda iimpawu zolawulo lwevolthi yetransformer, unokuqinisekisa ukuba iyakwazi ukugcina ivolthi yokuphuma ezinzileyo phantsi kweemeko ezahlukeneyo zomthwalo, ngaloo ndlela inciphisa umngcipheko wokuguquguquka kwevolthi okunokuchaphazela ukusebenza kwezixhobo ezixhunyiweyo.

Inyathelo lesi-4: Bala ukusebenza kakuhle

Ukusebenza kakuhle yenye into ebalulekileyo ekufuneka iqwalaselwe ngobukhulu be-transformer, njengoko ichaphazela ngokuthe ngqo ukusetyenziswa kwamandla kunye neendleko zokusebenza kwe-transformer. Ukusebenza kakuhle kwe-transformer kukulinganisa umlinganiselo wamandla okukhupha amandla okufaka, ochazwa njengepesenti, kwaye ubonakalisa amandla e-transformer okuguqula amandla ombane ngokulahlekelwa okuncinci.

Ukuze ubale ukusebenza kakuhle kwe-transformer, kuya kufuneka usebenzise le fomyula:

Ukusebenza kakuhle = (Amandla okukhupha / Amandla okufaka) × 100

Apho:

Amandla okukhupha = Amandla okukhupha umthwalo kwii-kilowatts (kW)

Amandla okufaka = Amandla apheleleyo okufaka kwii-kilowatts (kW)

Ngokumisela ngokuchanekileyo ukusebenza kakuhle kwe-transformer, ungavavanya ukusebenza kwayo kwamandla kwaye ukhethe imodeli eya kunciphisa ilahleko yamandla kunye neendleko zokusebenza ngelixa ihlangabezana neemfuno zomthwalo wenkqubo yombane.
