Iisokhethi zekhebula ze-voltage ephezulu (HV)zidlala indima ebalulekileyo kwiinkqubo zokuhambisa umbane kunye nokusasazwa kombane. Ezi sockets zenzelwe ukuqhagamshela ngokukhuselekileyo nangokufanelekileyo iintambo ze-voltage ephezulu kwizixhobo ezahlukeneyo zombane ezifana nee-transformers, ii-switchgear kunye nee-circuit breakers. Ngaphandle kwee-cable outlets ezithembekileyo nezisemgangathweni ophezulu, ukuthembeka kunye nokusebenza kakuhle kwenkqubo yombane yonke kunokuphazamiseka.
Omnye wemisebenzi ephambili yeesokhethi zekhebula ezinombane ophezulu kukubonelela ngoqhagamshelo olukhuselekileyo nolugqunyiweyo kwiintambo zombane eziphezulu. Ezi sokhethi zenzelwe ngokukodwa ukusingatha ii-voltage eziphezulu kunye nemisinga efana neenkqubo zombane ezine-voltage ephezulu. Ngokubonelela ngoqhagamshelo olukhuselekileyo noluthembekileyo, iisokhethi zekhebula ezinombane ophezulu zinceda ukunciphisa umngcipheko weempazamo zombane, ii-arcs, kunye nee-short circuits ezinokukhokelela ekucinyweni kombane, ekonakaleni kwezixhobo, nakwiingozi zokhuseleko.
Ukongeza ekuboneleleni ngoqhagamshelo lombane olukhuselekileyo, iisokhethi zekhebula ezine-voltage ephezulu zidlala indima ebalulekileyo ekwenzeni kube lula ukudluliselwa kwamandla ngokufanelekileyo. Ngokusebenzisa izixhobo zokukhusela eziphucukileyo kunye nobuchwepheshe boyilo, iisokhethi zekhebula ezine-voltage ephezulu zinokunciphisa ngempumelelo ukulahleka kwamandla kwaye ziqinisekise ukuba inani eliphezulu lamandla lifikelela kwindawo ebekiweyo. Oku kubaluleke kakhulu kwizicelo zokudluliselwa komgama omde, apho nelahleko encinci inokuba nefuthe elikhulu ekusebenzeni kakuhle kwenkqubo yamandla iyonke.
Enye into ebalulekileyo kwiisokhethi zekhebula ezinombane ophezulu kukukwazi kwazo ukumelana nemingeni yokusingqongileyo kunye nokusebenza efumaneka kwiinkqubo zothumelo kunye nokusasazwa. Ezi zikhongozeli zihlala zifakelwa ngaphandle okanye kwiindawo zoshishino ezinzima, apho zichatshazelwa khona kubushushu obugqithisileyo, ukufuma, kunye noxinzelelo loomatshini. Ke ngoko, iisokhethi zekhebula ezinombane ophezulu kufuneka zibe ziqinile, zikhuseleke kakhulu kwaye zichasane nezinto zokusingqongileyo ukuqinisekisa ukuthembeka nokusebenza ixesha elide.
Ukongeza, iisokhethi zekhebula ezinombane ophezulu ziyinxalenye ebalulekileyo yokusebenza ngokukhuselekileyo nangokufanelekileyo kwezixhobo ezinombane ophezulu. Ngokubonelela ngoqhagamshelo olukhuselekileyo nolugqunyiweyo, ezi sokhethi zinceda ukunciphisa umngcipheko weengozi zombane kwaye ziqinisekise ukhuseleko lwabasebenzi bokulungisa kunye nabanye abasebenzi abanokudibana nenkqubo yombane. Ukongeza, ukusebenzisa iisokhethi zekhebula ezinombane ophezulu ezikumgangatho ophezulu kunokunceda ukuphucula ukuthembeka kunye nokufumaneka kwenkqubo yombane, kunciphisa amathuba okucima kombane okungalindelekanga kunye nexesha lokungasebenzi.
Isishwankathelo,iisokhethi zekhebula ezine-voltage ephezuluzizinto ezibalulekileyo kwiinkqubo zokuhambisa umbane kunye nokusasazwa kwamandla. Ngokubonelela ngoqhagamshelo olukhuselekileyo nolusebenzayo kwiintambo ze-voltage ephezulu, ezi ndawo zokungenisa umbane zinceda ekuqinisekiseni ukuthembeka, ukusebenza kakuhle kunye nokhuseleko lwenkqubo yombane. Xa ukhetha isokhethi yentambo ye-voltage ephezulu kwisicelo esithile, kubalulekile ukuqwalasela izinto ezifana nokulinganiswa kwe-voltage kunye nombane, iimpawu zokufakelwa ubushushu, ukhuseleko lokusingqongileyo kunye nokuthobela imigangatho nemigaqo efanelekileyo. Ngokukhetha iindawo zokungenisa umbane ezifanelekileyo kunye nokuzifaka ngokuchanekileyo, abaqhubi beenkqubo zombane banokunceda ukwandisa ukusebenza kunye nokuthembeka kweziseko zabo zophuhliso.
