Intshayelelo

Ii-transformer windings zidlala indima ebalulekileyo ekusebenzeni kwee-power transformers, ezibalulekileyo ekudluliseni nasekusasazeni amandla ombane. Ukuqinisekisa ukusebenza ngokukhuselekileyo nangokufanelekileyo kwee-transformers, kubalulekile ukuba nokuqonda okubanzi koluhlu lobushushu bee-transformer winding. Eli nqaku liza kujonga iinkalo ezahlukeneyo zamaqondo obushushu e-transformer winding, ukubaluleka kwawo, kunye nezinto ezizichaphazelayo.

I. Ukubaluleka kobushushu bokujika kweTransformer

Ii-transformer windings zinoxanduva lokuguqula ii-voltage kunye nemisinga, nto leyo ezenza zibe yimfuneko ekusebenzeni ngokubanzi kweenkqubo zamandla. Ubushushu apho ezi windings zisebenza khona buchaphazela ngokuthe ngqo ukusebenza kwe-transformer, ixesha elide, kunye nokuthembeka kwayo. Kubalulekile ukugcina ubushushu obufanelekileyo bokujikisa ukuze isebenze kakuhle kwaye kuthintelwe nawuphi na umonakalo onokubakho.

II. Uluhlu lobushushu bokusebenza olukhuselekileyo

Iitransformer zenzelwe ukusebenza ngaphakathi koluhlu oluthile lobushushu ukuqinisekisa ukuba zihlala ixesha elide kwaye zikhuselekile. Ngokubanzi, ubushushu bokujika kufuneka bugcinwe bungaphantsi komda ochazwe ngumvelisi. Uluhlu lobushushu bokusebenza kwetransformer olukhuselekileyo kwiitransformer windings luhlala luphakathi kwama-80°C ukuya kwi-110°C (176°F ukuya kuma-230°F). Ukusebenza ngaphakathi kolu luhlu kunceda ukuthintela ukonakala kwezinto zokukhusela kwaye kuqinisekisa ukusebenza kakuhle kwetransformer.

Uhlobo kunye nemeko yezinto zokwambathisa ezisetyenziswa kwii-transformer windings zichaphazela kakhulu ukusebenza kwazo kobushushu. Izinto zokwambathisa ezahlukeneyo zinezinga lobushushu bokwambathisa i-transformer elahlukileyo, kwaye ukonakala kwazo ngokuhamba kwexesha kunokuchaphazela ukusebenza kwayo iyonke. Uvavanyo kunye nokugcinwa rhoqo kwe-insulation kuyimfuneko ukuthintela ukwaphuka kwe-insulation kunye nokushisa kakhulu.

E. Ukulayisha kakhulu kunye neesekethe ezimfutshane

Ukulayisha kakhulu okanye iisekethe ezimfutshane kunokubangela ukunyuka okukhulu kobushushu kwii-transformer windings. Iinkqubo kufuneka zihlalutywe ngokupheleleyo ukuze kujongwe iimeko ezinokubakho zeempazamo kwaye kufuneka kubekho iindlela zokukhusela ukuthintela ukuveliswa kobushushu obugqithisileyo. Izixhobo zokukhusela iisekethe ezifanelekileyo kunye neenkqubo zokubeka esweni zidlala indima ebalulekileyo ekugcineni amazinga obushushu akhuselekileyo.

IV. Ukubeka esweni ubushushu kunye nemigaqo

Ukuqinisekisa ukusebenza okukhuselekileyo nokuthembekileyo, amaqondo obushushu e-transformer winding kufuneka abekwe esweni rhoqo. Izinzwa zobushushu, ezifana nezifumanisi zobushushu bokumelana (ii-RTD) okanye ii-thermocouples, zihlala zifakelwa ngaphakathi kwe-windings ukuze zibonelele ngokufundwa kobushushu okuchanekileyo. Iinkqubo zokubeka esweni ziphakamisa ii-alamu okanye ziqalise amanyathelo okukhusela ukuba amaqondo obushushu adlula umlinganiselo ovumelekileyo.

Imibutho elawulayo kunye nemibutho yemigangatho, efana ne-Institute of Electrical and Electronics Engineers (IEEE), ichaze izikhokelo kunye nemigaqo malunga nemida yobushushu bokujika kwe-transformer. Ukuthobela le migaqo kuqinisekisa ukusebenza ngokukhuselekileyo kwe-transformers kunye neenkqubo zombane ezingqongileyo.

V.Ungalinganisa njani ubushushu obujikelezayo be-transformer?

Ukuze ulinganise ngokuchanekileyo ubushushu bokujika kwe-transformer, umntu kufuneka asebenzise indibaniselwano yeendlela eziphambili kunye nezixhobo ezithembekileyo ukuqinisekisa ukujonga ngokuchanekileyo iimeko zobushushu. Ukusetyenziswa kwezixhobo zokubona ubushushu bokumelana (ii-RTD) okanye ii-thermocouples ezibekwe ngendlela eyiyo ngaphakathi kwesakhiwo sokujika kuvumela uvavanyo lwexesha langempela lobushushu bokujika kwe-transformer ngexesha lokusebenza. Ezi zixhobo zisebenza njengezinzwa ezithe ngqo, zibonelela ngedatha ebalulekileyo ngokuguqula amandla obushushu abe ziimpawu zombane ngokulingana notshintsho lobushushu olubonwa kwiinzwa. Ukuze kuphuculwe ukuchaneka, kubalulekile ukulinganisa ezi sensor rhoqo ngokuchasene nemigangatho eyaziwayo kwaye uqwalasele izinto ezifana nokutshintsha kobushushu obuphakathi kunye neemeko zomthwalo ezinokuchaphazela ukufundwa. Ukongeza, ukudibanisa inkqubo ebanzi yokubeka esweni egcina le datha kunokwenza kube lula uhlalutyo lwendlela ngokuhamba kwexesha, kuvumela amaqhinga okugcina kwangaphambili ajolise ekuphuculeni ukusebenza kunye nokuthintela iimeko zokushisa kakhulu ezinokuphazamisa ingqibelelo ye-transformer. Ii-multimeters zedijithali eziphambili okanye iikhamera zemifanekiso yobushushu ezizinikeleyo nazo zinokusetyenziswa ngamaxesha athile kuvavanyo olungenalo uhlaselo, ukuqinisekisa indlela ebanzi yokulawula impilo ye-transformer ngokujonga ngononophelo ubushushu bayo bokujika.
