Intshayelelo
Iintambo ze-voltage ephezuluzizinto ezibalulekileyo kwiintlobo ngeentlobo zezicelo zobuchwepheshe, zibonelela ngamandla afunekayo kunye noqhagamshelo lwezixhobo ezisebenza kumanqanaba aphezulu ombane. Ezi ntambo zenzelwe ukumelana noxinzelelo oluphezulu lombane, ukuqinisekisa ukhuseleko kunye nokusebenza kakuhle kwizicelo zazo. Njengoko ubuchwepheshe buqhubeka buhambela phambili, imfuno yeentambo ezinokwethenjelwa zombane ophezulu iye yanda, ngakumbi kwiindawo ezifana nemifanekiso yezonyango, uphando lwemizi-mveliso, kunye nezixhobo zovavanyo.
Umsebenzi kunye nokubaluleka
Umsebenzi oyintloko weentambo ze-high-voltage kukudlulisa amandla ombane ngokukhuselekileyo nangokufanelekileyo kumgama omde. Ezi ntambo zenzelwe ukumelana nee-voltage eziphezulu, ezidla ngokudlula i-1,000 volts. Ukubaluleka kwazo akupheleli nje ekukwazini kwazo ukudlulisa amandla, kodwa nakwindima yazo ekuqinisekiseni ukhuseleko lwabasebenzisi kunye nezixhobo. Iintambo ze-high-voltage zenziwe nge-insulation eqinileyo kunye nezigqubuthelo zokukhusela ezithintela ukuvuza kwaye zinciphise umngcipheko weengozi zombane. Oku kuzenza zingabi yimfuneko kwiindawo apho ukuchaneka nokhuseleko kubaluleke kakhulu.
Amasimi esicelo
Iintambo zombane ophezulu zisetyenziswa kwiintlobo ngeentlobo zezicelo, nganye ineemfuno kunye nemingeni eyahlukileyo. Nazi iindawo ezintathu eziphambili apho ezi ntambo zidlala indima ebalulekileyo:
Izixhobo ze-X-ray zonyango: Iintambo zombane ophezulu ziyinxalenye ebalulekileyo yetekhnoloji yokujonga imifanekiso yezonyango, kubandakanya oomatshini be-X-ray abaqhelekileyo, ii-scanner ze-computed tomography (CT), kunye nezixhobo ze-angiography. Ezi zixhobo zifuna i-voltage ephezulu ukuvelisa ii-X-ray, ezibalulekileyo ekuxilongeni nasekujongeni iimeko ezahlukeneyo zonyango. Ukuthembeka kweentambo zombane ophezulu kuqinisekisa ukuba ezi matshini zisebenza kakuhle, zibonelela ngemifanekiso ecacileyo nechanekileyo kwiingcali zonyango.
Izixhobo ze-X-ray okanye ze-electron beam zoshishino nezenzululwazi: Kwiimeko zoshishino nezenzululwazi, iintambo ze-voltage ephezulu zisetyenziswa kwizixhobo ezifana nee-electron microscopes kunye neenkqubo ze-X-ray diffraction. Ezi zicelo zifuna ulawulo oluchanekileyo lwe-voltage ephezulu ukuvelisa imifanekiso eneenkcukacha kunye nokuhlalutya izixhobo kwinqanaba le-microscopic. Ukusebenza kwezi nkqubo kuxhomekeke kakhulu ekuthembekeni kweentambo ze-voltage ephezulu, ekufuneka zigcine iipropati zombane ezihambelanayo ukuqinisekisa iziphumo ezichanekileyo.
Izixhobo zovavanyo oluphezulu lwamandla aphantsi kunye nezixhobo zokulinganisa: Iintambo zombane ophezulu zikwasetyenziswa kwizixhobo zovavanyo nokulinganisa ezenzelwe ukusetyenziswa kwamandla aphantsi. Ezi zixhobo zibalulekile ekuvavanyeni ukusebenza nokhuseleko lweenkqubo zombane, izinto kunye nezixhobo. Iintambo zombane ophezulu zenza kube lula inkqubo yovavanyo ngokubonelela ngonxibelelwano oluzinzileyo noluthembekileyo, okuvumela iinjineli kunye neengcali ukuba zenze uvavanyo olupheleleyo ngaphandle kokubeka emngciphekweni ukhuseleko.
Isiphelo
Isishwankathelo,iintambo zombane eziphezuluzizinto ezibalulekileyo kwiintlobo ngeentlobo zezicelo, ukusuka kwimifanekiso yezonyango ukuya kuphando lwemizi-mveliso kunye novavanyo. Amandla abo okudlulisa ngokukhuselekileyo amandla aphezulu ombane ngelixa beqinisekisa ukuthembeka kwezixhobo abazisebenzelayo kubalulekile ekuphuculeni ubuchwepheshe kwezi ndawo. Njengoko amashishini eqhubeka nokukhula kwaye efuna izixhobo eziphucukileyo, ukubaluleka kweentambo eziphezulu zombane kuya kukhula kuphela. Ukutyala imali kwiintambo ezikumgangatho ophezulu akuyi kuphucula kuphela ukusebenza kwezixhobo zakho, kodwa kuya kukhusela nempilo yabaqhubi kunye nezigulane. Ukuqonda ukubaluleka kwezi ntambo kubalulekile kuye nabani na obandakanyekayo kuyilo, ukusebenza, okanye ukugcinwa kweenkqubo eziphezulu zombane.
