High voltage resistorstchulani zida zodzitetezera zomwe zimatha kupirira ma voltages apamwamba. Nthawi zambiri, ma resistors okhala ndi voteji ya 1 kV (kilovolts) ndi pamwambapa amatchedwa high voltage resistors, ndipo ma voliyumu ovotera a high-voltage resistors amatha kufikira mazana a ma kilovolts.
Pali mitundu yambiri ndi mapangidwe a high voltage resistors. The resistivity of high-voltage resistors ndi apamwamba, ndipo mphamvu ya dielectric ya zinthu zomwezo ndizokwera kwambiri. Chifukwa chake, imatha kugwira ntchito mokhazikika m'malo ovuta kwambiri monga ma voliyumu apamwamba, kutentha kwambiri, komanso chinyezi chambiri. Kuphatikiza apo, ma resistors apamwamba kwambiri amafunikanso kukhala ndi mphamvu zokwanira zotsekereza komanso zinthu zoteteza chinyezi kuti zisawonongeke pansi pa minda yamagetsi yamagetsi. Ngati pali zofunikira zapadera, ziyeneranso kukhala ndi makhalidwe monga anti-high frequency, anti-interference, overload, ndi chitetezo cha moto.
Chifukwa chake, ma resistors apamwamba kwambiri ndi zida zolimbana ndi zolondola kwambiri, zodalirika kwambiri komanso kukana kwamagetsi. Amagwiritsidwa ntchito kwambiri pamagetsi othamanga kwambiri, zida zoyesera, zida zamagetsi, makina ozindikira zithunzi, ma accelerator a tinthu ndi magawo ena.
Chifukwa chake,high voltage resistorsali ndi makhalidwe asanu ndi awiri awa:
High Voltage: Ma voltage resistor apamwamba amakhala ndi ma voliti apamwamba kwambiri ndipo amatha kupirira ma voltages kuyambira masauzande mpaka mazana a ma kilovolts.
Mtengo wotsutsa kwambiri: Popeza kuti ma resistors apamwamba kwambiri nthawi zambiri amagwiritsidwa ntchito pamagetsi apamwamba kwambiri, kukana kwawo nthawi zambiri kumakhala kwakukulu ndipo kumatha kufikira mazana a megaohms kapena kupitilira apo.
High voltage resistance: High voltage resistors imayenera kugwira ntchito mokhazikika m'malo okhala ndi mphamvu zambiri.
Okhazikika kwambiri: Otsutsa othamanga kwambiri amafunika kugwira ntchito m'malo othamanga kwambiri komanso kutentha kwambiri kwa nthawi yayitali, kotero kukhazikika kwawo ndi kudalirika kwawo kumafunika kutsimikiziridwa. Kukhazikika kwamafuta abwino: Zopinga zamphamvu kwambiri zimatha kugwedezeka chifukwa cha kutentha kwambiri, kotero zopinga zamphamvu kwambiri zokhala ndi kukhazikika kwamafuta zimatha kuwonetsetsa kulondola kwa dera.
Kutchinjiriza kwakukulu: Zopinga zamphamvu kwambiri ziyenera kukhala ndi zida zabwino zotchinjiriza kuti zipewe zovuta zachitetezo monga kuwonongeka kwa magetsi ndi kutayikira.
Kulondola kwambiri: Zopinga zamphamvu kwambiri zimagwiritsidwa ntchito kwambiri m'mabwalo kapena zida zomwe zimafuna kulondola kwambiri, kotero kulondola kwapamwamba ndikofunikira. Kutengera ndi zomwe zili pamwambazi, zinthu zisanu ndi chimodzi zotsatirazi ziyenera kuganiziridwa posankha ma high-voltage resistors:
Voltage yovoteledwa: Ndikofunikira kutsimikizira ngati voliyumu yamagetsi osankhidwa apamwamba amakwaniritsa zofunikira zenizeni. Posankha resistor, muyenera kuonetsetsa kuti voteji yake oveteredwa ndi apamwamba kuposa voteji ntchito dera, makamaka kuposa kawiri, kuonetsetsa kuti resistor si kulephera kapena kuwonongeka pa ntchito.
Mtengo wa Resistor: Mtengo wotsutsa wamagetsi osankhidwa okwera kwambiri uyenera kutsimikiziridwa kutengera ntchito yozungulira yofunikira komanso kapangidwe kake.
Ngati mukufunikira kuchepetsa mphamvu zambiri, mukhoza kusankha mtengo wapamwamba wotsutsa; ngati mukufuna kupirira panopa pa voteji mkulu, mukhoza kusankha otsika resistor mtengo.
Kulondola kwa resistor: M'mabwalo olondola kwambiri kapena zida,high voltage resistorsndi zolondola zapamwamba ziyenera kusankhidwa. Ngati kulondola kwa dera sikwapamwamba, mutha kusankha chopinga chachikulu chamagetsi ndi kulondola kwathunthu.
Kudalirika: Ndikofunikira kusankha zopinga zamphamvu kwambiri zomwe zimatha kugwirabe ntchito mokhazikika pakutentha kwambiri, chinyezi chambiri, kuipitsidwa ndi malo ena. Kwa mabwalo omwe amagwiritsidwa ntchito nthawi yayitali kapena mosalekeza, ndikofunikira kusankha zopinga zamphamvu kwambiri zodalirika zodalirika.
Kuteteza chilengedwe: Ndi kuwongolera kwa chidziwitso cha chilengedwe, zoteteza zachilengedwe zowongoka bwino zalandiranso chidwi chochulukirapo. Ndikofunikira kusankha zinthu zamphamvu kwambiri zomwe zimakwaniritsa miyezo yoteteza chilengedwe.
Chizindikiro: Ndikwabwino kusankha opanga ndi ma brand omwe amawonekera kwambiri, mbiri yabwino komanso mtundu wotsimikizika.
