Ukuqhuba Okuphuculweyo Kobushushu

Ukusasazwa kobushushu okusebenzayo kubalulekile ekusebenzeni okuthembekileyo kweetransformer. Ukusonga ngefoyile kuphucula kakhulu ukuhanjiswa kobushushu xa kuthelekiswa neendlela zendabuko zokusonga ngentambo. Iifoyile ezincinci zivumela ukudluliselwa kobushushu okungcono phakathi kweewindings kunye nendawo yokupholisa ejikelezileyo. Ukuphuculwa kokuhanjiswa kobushushu kuqinisekisa ukuba itransformer isebenza kumaqondo obushushu aphantsi, kunciphisa umngcipheko wokwaphuka kobushushu kwaye kwandise ubomi beyunithi. Ngokugcina amaqondo obushushu afanelekileyo okusebenza, ukusonga ngefoyile kunceda ekuqiniseni ukuthembeka kunye nobude bexesha leetransformer.

Uxinzelelo loMbane oluNciphisiweyo

Ii-transformer windings ziphantsi koxinzelelo lombane olwahlukeneyo ngexesha lokusebenza, njenge-voltage transients kunye ne-high-frequency harmonics. I-foil winding inika iingenelo ngokubhekiselele kuxinzelelo lombane oluphantsi. Ukusetyenziswa kwee-foils ezinommandla ophezulu womphezulu kunye neendlela ezihamba kunye ne-conductive kubangela ukuba i-winding capacitance ibe phantsi kunye nokumelana ne-AC. Oku kunciphisa ubukhulu be-voltage transients kunye ne-harmonics, kuphucula umgangatho we-voltage waveform kunye nokunciphisa uxinzelelo kwi-insulation. Ngokunciphisa uxinzelelo lombane, i-foil winding inegalelo kwi-transformer eqinileyo nethembekileyo, inciphisa amathuba okungaphumeleli kunye nexesha lokungasebenzi.

Uzinzo olungcono lweMishini

Uzinzo loomatshini luyinto ebalulekileyo kuyilo lwe-transformer, ingakumbi kwii-transformer ezinkulu zamandla ezisebenza phantsi kweemeko ezinzima. Ukugoba ngefoyile kubonelela ngozinzo loomatshini oluphezulu xa kuthelekiswa nokugoba ngentambo yesiqhelo. Iifoyile ezibhityileyo nezithe tyaba, xa zibotshelelwe kwaye zibotshelelwe ngokuqinileyo, zenza isakhiwo esincinci nesiqinileyo. Oku kususa umngcipheko wokuhamba kwentambo, ukungcangcazela, okanye ukukhululeka ngenxa yokwanda kobushushu okanye amandla e-electromagnetic. Uzinzo loomatshini oluphuculweyo olunikezelwa kukugoba ngefoyile luqinisekisa ukuba ii-windings zihlala zizinzile endaweni yazo, zinciphisa umngcipheko wokonakala kwe-insulation kwaye ziqinisekisa ukuthembeka kwexesha elide.

Ukuphucula Amandla Okumelana Nesekethe Emfutshane

Iitransformer kufuneka zinyamezele ii-short circuits ezinokubangelwa ziimpazamo kwinkqubo yombane. Ukujija ngefoyile kunika amandla okuphucula ukumelana nee-short circuit xa kuthelekiswa neendlela zokujija ngentambo. Ukusetyenziswa kweefoyile kuvumela indawo enkulu enqamlezileyo, kunciphisa ukumelana nee-winding kunye ne-impedance. Oku kubangela ukuba i-fault currents ibe sezantsi kwaye kuphuculwe ukusebenza koomatshini kunye nobushushu ngexesha le-short circuit. Ngokumelana nee-short circuits ngempumelelo, iitransformer ezine-foyile zibonelela ngokuthembeka kwenkqubo okuphuculweyo kunye nexesha lokungasebenzi elinciphileyo.
