Zisebenza njani iitshaja eziKhawulezayo zokupholisa ulwelo?

Iitshaja ezikhawulezayo zokupholisa ulwelo zisebenzisa iintambo ezipholise ulwelo ukunceda ukulwa amaqondo aphezulu obushushu anxulumene nezantya zokutshaja eziphezulu. Ukupholisa kwenzeka kwikhonkco ngokwayo, ukuthumela i-coolant ehamba ngentambo kunye noqhagamshelwano phakathi kwemoto kunye nekhonkco. Ngenxa yokuba ukupholisa kwenzeka ngaphakathi kwesinxibelelanisi, ubushushu buyaphela phantse ngoko nangoko njengoko isisipholisi sihamba sibuya siphindela phakathi kweyunithi yokupholisa kunye nesihlanganisi. Iinkqubo zokupholisa ulwelo ezisekelwe emanzini zinokuchitha ubushushu ukuya kutsho kumaxesha ali-10 ngokufanelekileyo, kwaye olunye ulwelo lunokuphucula ngakumbi ukusebenza kakuhle kokupholisa. Ke ngoko, ukupholisa ulwelo kwamkela ngakumbi nangakumbi ingqwalasela njengesona sisombululo sisebenzayo sikhoyo.

Ukupholisa ulwelo kuvumela iintambo zokutshaja ukuba zibe mfutshane kwaye zibe khaphukhaphu, ukunciphisa ubunzima bekhebula malunga ne-40%. Oku kwenza kube lula kumthengi oqhelekileyo ukuba asebenzise xa ebiza isithuthi sakhe.

Izihlanganisi zolwelo lokupholisa ulwelo ziyilelwe ukuba zomelele kwaye zimelane neemeko zangaphandle ezifana namazinga aphezulu obushushu, ukubanda, ukufuma nothuli. Zikwayilelwe ukuba zimelane noxinzelelo olukhulu lokunqanda ukuvuza kunye nokuzigcina ngamaxesha amade okutshaja.

Inkqubo yokupholisa ulwelo kwiitshaja zesithuthi sombane ibandakanya inkqubo evaliweyo. Itshaja ixhotyiswe ngesixhobo sokutshintsha ubushushu esiqhagamshelwe kwisixokelelwano sokupholisa, esinokuthi sipholiswe ngumoya okanye sipholiswe ngamanzi. Ubushushu obuveliswe ngexesha lokutshaja bukhutshelwa kwisixhobo sokutshintsha ubushushu, size sibudlulisele kwisipholisi. Ukupholisa ngokuqhelekileyo ngumxube wamanzi kunye nesongezo esipholileyo, esifana ne-glycol okanye i-ethylene glycol. Isipholisi sijikeleza kwisixokelelwano sokupholisa setshaja, sifunxa ubushushu kwaye sibudlulisele kwiradiyetha okanye kwisitshintshi sobushushu. Ubushushu buye bukhutshelwe emoyeni okanye budluliselwe kwinkqubo yokupholisa engamanzi, kuxhomekeke kuyilo lwetshaja.

Ingaphakathi le-high-power CSS connector ibonisa iintambo ze-AC (eziluhlaza) kunye nokupholisa ulwelo kwiintambo ze-DC (ezibomvu).

Ngokupholisa ulwelo kubafowunelwa kunye nesipholisi esisebenza kakhulu, umlinganiselo wamandla unokunyuswa ukuya kuthi ga kwi-500 kW (500 A kwi-1000V) enokunikezela ngentlawulo yoluhlu lweemayile ezingama-60 kwimizuzu nje emithathu ukuya kwemihlanu.
