High voltage resistorsbhekisela kumadivayisi aphikisayo akwazi ukumelana nama-voltage aphezulu. Ngokuvamile, ama-resistors ane-voltage elinganiselwe engu-1 kV (kilovolts) nangaphezulu abizwa ngokuthi ama-resistors kagesi aphezulu, futhi i-voltage elinganiselwe yama-resistors aphezulu-voltage ingafinyelela kumakhulu ama-kilovolts.
Kunezinhlobo eziningi nezakhiwo ze-high voltage resistors. I-resistivity ye-high-voltage resistors iphezulu, futhi amandla e-dielectric wento ngokwayo nawo aphezulu. Ngakho-ke, ingasebenza ngokuzinza ezindaweni ezinzima njengamandla kagesi aphezulu, izinga lokushisa eliphezulu, nomswakama ophezulu. Ukwengeza, izinto ezivimbela amandla kagesi aphezulu nazo zidinga ukuba namandla okufaka okwanele kanye nezakhiwo zokuvikela umswakama ukuze zigweme ukuwohloka ngaphansi kwamasimu kagesi aphezulu. Uma kunezidingo ezikhethekile, kufanele futhi ibe nezici ezifana ne-anti-high frequency, anti-interference, overload, nokuvikela umlilo.
Ngakho-ke, ama-resistors aphezulu kagesi angamadivayisi aphikisayo anembayo ephezulu, enokwethenjelwa kakhulu kanye nokumelana nomthamo ophezulu. Asetshenziswa kakhulu ezintweni zamandla kagesi aphezulu, amathuluzi okuhlola, amathuluzi kagesi, amasistimu wokuqaphela izithombe, ama-accelerator ezinhlayiyana neminye imikhakha.
Ngakho-ke,high voltage resistorsabe nezici eziyisikhombisa ezilandelayo:
Amandla Amandla Kagesi Aphezulu: Izinqamuleli zamandla kagesi aphezulu zinezilinganiso zamandla kagesi aphezulu futhi zingamelana nokuphakama kwezinkulungwane kuya kumakhulu amakhilovolthi.
Inani eliphakeme lokumelana: Njengoba izinto ezimelana namandla kagesi aphezulu zivame ukusetshenziswa ezinhlelweni zamandla kagesi aphezulu, amanani awo okumelana avame ukuba makhulu futhi angafinyelela kumakhulu ama-megaohm noma ngaphezulu.
Ukumelana ne-voltage ephezulu: Ama-resistors kagesi aphezulu adinga ukusebenza ngokuzinzile ezindaweni ezinama-voltage aphezulu.
Izinze kakhudlwana: Ama-resistors ane-voltage ephezulu adinga ukusebenza ezindaweni ezinomfutho ophezulu kanye nezinga lokushisa eliphezulu isikhathi eside, ngakho-ke ukuzinza nokuthembeka kwazo kudinga ukuqinisekiswa. Ukuzinza okuhle kwe-thermal: Ama-resistors aphezulu-amandla kagesi ajwayele ukukhukhuleka ngenxa yamazinga okushisa aphezulu, ngakho-ke izinto eziphikisa amandla kagesi aphezulu ezinokuzinza okuhle kwe-thermal zingaqinisekisa kangcono ukunemba kwesifunda.
I-insulation ephezulu: Izinto ezimelana namandla kagesi aphezulu zidinga ukuba nezinto ezinhle zokuvikela ukuze zigweme izinkinga zokuphepha njengokuphuka kukagesi nokuvuza.
Ukunemba okuphezulu: Izimbangi zamandla kagesi aphezulu zisetshenziswa kakhulu kumasekhethi noma amathuluzi adinga ukunemba okuphezulu, ngakho ukunemba okuphezulu kuyadingeka. Ngokusekelwe ezicini ezingenhla, izici ezilandelayo eziyisithupha zidinga ukucatshangelwa lapho kukhethwa izimbangi ezinamandla kagesi:
I-voltage elinganiselwe: Kuyadingeka ukuqinisekisa ukuthi i-voltage elinganiselwe ye-high-voltage resistor ekhethiwe iyahlangabezana nezidingo zangempela. Lapho ukhetha i-resistor, kufanele uqinisekise ukuthi i-voltage yayo elinganiselwe iphakeme kune-voltage yokusebenza yesekethe, okungcono ngaphezu kokuphindwe kabili, ukuze uqinisekise ukuthi i-resistor ngeke ihluleke noma yonakaliswe ngesikhathi sokusetshenziswa.
Inani le-Resistor: Inani lokumelana le-high voltage resistor ekhethiwe lidinga ukunqunywa ngokusekelwe emsebenzini wesifunda odingekayo kanye nezidingo zokuklama.
Uma udinga ukunciphisa i-voltage ephezulu, ungakhetha inani eliphakeme le-resistor; uma udinga ukumelana namanje ku-voltage ephezulu, ungakhetha inani eliphansi le-resistor.
Ukunemba kwe-Resistor: Kumasekhethi anembe kakhulu noma amathuluzi,high voltage resistorsngokunemba okuphezulu kudingeka kukhethwe. Uma ukunemba kwesifunda kungaphakeme, ungakhetha i-high-voltage resistor ngokunemba okuvamile.
Ukuthembeka: Kudingeka ukukhetha izimelambisi ezinamandla ezinamandla ezingase zisebenze ngokuzinza kumazinga okushisa aphezulu, umswakama ophezulu, ukungcola nezinye izindawo. Kumasekhethi anokusetshenziswa isikhathi eside noma okuqhubekayo, kuyadingeka ukukhetha ama-resistors aphezulu-voltage ngokuthembeka okuhle.
Ukuvikelwa kwemvelo: Ngokuthuthukiswa kokuqwashisa ngemvelo, izinto eziphikisana nemvelo ezinogesi ophezulu nazo zithole ukunakwa okwengeziwe. Kuyadingeka ukukhetha imikhiqizo ene-voltage resistor ephezulu ehlangabezana nezindinganiso zokuvikela imvelo.
Ibhrendi: Kungcono kakhulu ukukhetha abakhiqizi nemikhiqizo ebonakalayo ephezulu, idumela elihle kanye nekhwalithi eqinisekisiwe.
