High Voltage Resistorszizixhobo ezixhathisayo ezinokumelana nombane ophezulu. Ngokuqhelekileyo, i-resistors ene-voltage elinganisiweyo ye-1 kV (i-kilovolt) nangaphezulu ibizwa ngokuba yi-resistors yombane ophezulu, kwaye i-voltage elinganisiweyo ye-resistors ephezulu yombane inokufikelela kumakhulu eekhilovolthi.
Kukho iintlobo ezahlukeneyo kunye nezakhiwo ze-resistors zombane ophezulu. Izichasi zamandla ombane aphezulu zinokuxhathisa okuphezulu kwaye imathiriyeli ngokwayo inamandla aphezulu e-dielectric, ke inokusebenza ngokuzinzileyo kwiindawo ezirhabaxa ezinje ngombane ophezulu, ubushushu obuphezulu, kunye nokufuma okuphezulu. Ukongeza, i-resistors ephezulu ye-voltage nayo kufuneka ibe namandla okwaneleyo okugquma kunye nokusebenza kobungqina bokufuma ukuphepha ukuwohloka okubangelwa yintsimi yombane ephezulu. Ukuba kukho iimfuno ezikhethekileyo, nazo kufuneka zibe neempawu ze-anti-high frequency, anti-interference, overload and fire protection.
Ke ngoko, izinto ezixhathisa amandla ombane aphezulu luhlobo lwezixhobo ezichasayo ezichaneke kakhulu, ukuthembeka okuphezulu kunye namandla ombane aphezulu okumelana, ezisetyenziswa ngokubanzi kwimimandla yobonelelo lwamandla ombane aphezulu, izixhobo zovavanyo, izixhobo zamandla ombane, iinkqubo zokuqaphela umfanekiso, iipedali zerhasi. kwaye nangokunjalo.
Ngoko kei-resistor yombane ophezuluinezi mpawu zisixhenxe zilandelayo:
Umbane oPhezulu:I-RI80 High Voltage Resistors inikwe umlinganiselo wombane ophezulu kwaye iyakwazi ukumelana namawaka ukuya kumakhulu eekilovolthi.
Ixabiso Eliphezulu Lokumelana:Kuba izichasi zombane ophezulu zihlala zisetyenziswa kwizicelo zombane ophezulu, ixabiso labo lokumelana lithande ukuba likhulu kwaye linokufikelela kumakhulu ee-megohms okanye ngaphezulu.
Umbane ophezulu wokumelana:Izichasi zombane eziphezulu kufuneka zisebenze ngokuzinzileyo kwiindawo zombane ophezulu.
Izinzile ngakumbi:I-resistors ephezulu yombane kufuneka isebenze phantsi koxinzelelo oluphezulu kunye nemeko yokushisa okuphezulu ixesha elide, ngoko ke ukuzinza kwabo kunye nokuthembeka kufuneka kuqinisekiswe.
Uzinzo oluhle lobushushu:I-RI80 i-resistors yombane ephezulu ithanda ukukhukuliseka ngenxa yobushushu obuphezulu, ngoko ke izichasi zombane eziphezulu ezinozinzo olufanelekileyo lwe-thermal zinokuqinisekisa ngcono ukuchaneka kwesekethe.
I-Insulation ephezulu:Izichasi zombane eziphezulu kufuneka zibe neempawu ezifanelekileyo zokugquma ukuthintela ukonakaliswa kombane kunye nokuvuza kunye neminye imiba yokhuseleko.
Ukuchaneka okuphezulu:Izixhasi eziphezulu ze-voltage zisetyenziswa kakhulu kwiisekethe okanye izixhobo ezifuna ukuchaneka okuphezulu, ngoko ke iqondo eliphezulu lokuchaneka liyimfuneko.
Ukushwankathela ezi mpawu zingentla, ezi zinto zintandathu zilandelayo kufuneka ziqwalaselwe xa kukhethwaizixhasi zombane eziphezulu:
Ulinganiso lombane:Kuyimfuneko ukuqinisekisa ukuba i-voltage elinganisiweyo ye-resistor ephezulu ekhethiweyo ihlangabezana neyona mfuno. Xa ukhetha i-resistor, kufuneka kuqinisekiswe ukuba i-voltage yayo elinganisiweyo iphezulu kune-voltage yokusebenza yesekethe, ngokukhethekileyo ngaphezu kokuphindwe kabini ukugqithisa ukuqinisekisa ukuba i-resistor ayiyi kuphumelela okanye yonakaliswe ngexesha lokusetyenziswa.
Ixabiso lokuchasa:Ixabiso lokuchasana le-resistor ephezulu ekhethiweyo kufuneka igqitywe ngokomsebenzi wesekethe oyifunayo kunye neemfuno zoyilo. Ukuba ufuna ukunciphisa i-voltage ephezulu, unokukhetha ixabiso eliphezulu lokumelana; ukuba ufuna ukumelana nombane phantsi kombane ophezulu, ungakhetha ixabiso eliphantsi lokumelana.
Ukuchasana nokuchaneka:Kwiisekethe ezichanekileyo okanye izixhobo ezichanekileyo, kuyimfuneko ukukhetha i-resistors high-voltage kunye ngokuchanekileyo okuphezulu. Ukuba ukuchaneka kwesekethe akukho phezulu, unokukhetha ukuchaneka ngokubanzi kokumelana nombane ophezulu.
Ukuthembeka:Kuyafuneka ukuba ukhethe izichasi zombane eziphezulu ezinokusebenza ngokuzinzileyo phantsi kobushushu obuphezulu, ukufuma okuphezulu, ungcoliseko kunye nezinye iimeko ezingqongileyo. Ukusetyenziswa kwexesha elide okanye okuqhubekayo kwesekethe, kufuneka ukhethe i-resistor high-voltage kunye nokuthembeka okulungileyo.
Ukhuseleko lokusingqongileyo:Ngokuphuculwa kolwazi lokhuseleko lokusingqongileyo, ukhuseleko lokusingqongileyo izichasi zombane ophezulu zikwafumana ingqwalasela eyongezelelekileyo. Kuyimfuneko ukuba ukhethe i-resistors high-voltage ehambelana nemigangatho yokusingqongileyo.
Uphawu:Kungcono ukhethe abavelisi kunye neempawu ezibonakalayo eziphezulu, idumela elihle kunye nomgangatho oqinisekisiweyo.
