Izihluthulelo zamandla aphezulu zivame ukusetshenziswa kuma-amplifiers aphezulu aphezulu kanye nemoto.
Zibuye zisetshenziswe ekusetshenzisweni kwezimboni nezokwelapha, phakathi kokunye.
Lezi resistors ziyabiza, yingakho ukutshala imali eyodwa kungesona isinqumo esilula.
Nokho, akwenzeki futhi.
Yiziphi Ama-High Power Resistors? Ama-resistors amandla aphezulu asetshenziswa uma udinga ukumelana okwengeziwe kusuka enanini elinikeziwe lamanje.
Uma liphakeme inani lokumelana, yilapho likwazi ukuliphatha ngokuphepha.
Uma uhlela ukusebenzisa isikhali sakho samandla aphezulu kokunye ngaphandle kokuhlola noma ukusebenzisa nje okuvamile, kungcono ukuthi uthenge nenguqulo yamandla aphansi.
Yini Okufanele Uyicabangele Lapho Uthenga I-High Power Resistor?
Kukhona ezinye izinto okudingeka uzicabangele ngenkathi uthenga i-resistor yamandla aphezulu.
Lokhu kufaka phakathi izilinganiso zamandla, ububanzi bokumelana, intengo, njll.
Uma ungenaso isiqiniseko nganoma yikuphi kwalokhu, ungahlala ubuza umdayisi noma uthole ulwazi oluningiliziwe mayelana nokuphikiswa kwamandla aphezulu ku-inthanethi.
Njengoba sekushiwo, ake sibheke lokho okudingeka ukwazi ngaphambi kokuthenga i-resistor yamandla aphezulu.
– I-High Power Resistors vs Low Power Resistors Kuningi ukudideka okuzungeze umehluko phakathi kwezinto eziphikisa amandla aphansi neziphikisayo zamandla aphezulu.
Lokhu kungenxa yokuthi zombili izinhlobo zokuphikisa zinomsebenzi ofanayo oyisisekelo - ukumelana nokugeleza kwamanje - futhi zisetshenziselwa izinhlelo zokusebenza ezahlukene.
Ukudideka kuphakama ngoba kokubili izinqamuleli zamandla aphezulu kanye nezinqamuleli zamandla aphansi zisetshenziswa kuma-amplifiers aphezulu ekupheleni.
Kodwa ama-resistors aphezulu aphezulu asetshenziselwa ezinye izinhlelo zokusebenza futhi.
– Izilinganiso Zamandla Eziphikisayo Zamandla Aphakeme Isilinganiso samandla esiphikisayo sibonisa ukumelana kwaso ngevolthi ngayinye.
Ngamanye amazwi, ikutshela ukuthi isifunda sakho singaphatha amandla angakanani.
Lokhu kubalulekile, ikakhulukazi uma ufuna ukusebenzisa amandla akho aphezulu ukumelana ne-amplifier noma umsakazo.
Uma i-amplifier yakho ingakwazi ukuphatha i-voltage ephezulu ekhiqizwa yisekethe yakho, ngeke isebenze kahle.
Ngakho-ke, usikhetha kanjani isilinganiso samandla esilungile se-resistor yakho yamandla aphezulu? Kunezinto ezimbalwa okufanele uzikhumbule.
Okokuqala, ingabe isifunda sakho siyisikhulisi samandla noma siwumthombo wamandla? Okwesibili, isifunda sakho sizokhiqiza okungakanani okwamanje? Okwesithathu, ingakanani i-voltage ezobe isetshenziswa yisekethe yakho? Uma wazi zonke lezi zinto, khona-ke ungakhetha i-resistor yamandla aphezulu ngokufanele.
- I-Resistance Range of High Power Resistors Yonke into ephikisayo inesilinganiso sokumelana, kodwa akubona bonke abaphikisayo abanobubanzi obufanayo bokumelana.
Ukuze uthenge isiphikisa esilungile sohlelo lwakho lokusebenza, udinga ukwazi ububanzi baso bokumelana.
Ngezinqamuleli zamandla aphezulu, ububanzi bokumelana ngokuvamile buphakathi kuka-150 Ω no-2 MΩ.
Kodwa ububanzi obuqondile buncike enanini le-resistor oyithengayo.
Lobu bubanzi banele ukunika amandla noma yiluphi uhlobo lwesistimu kagesi, ukusuka ama-amplifiers wemoto ezintweni zikagesi.
– Intengo High Power Resistors High amandla resistors azishibhile, ngakho-ke kubalulekile ukwazi intengo ngaphambi kokuyithenga.
Ngokuvamile ungathola lolu lwazi kuwebhu noma ekucacisweni komkhiqizo.
Uma kungenzeka, zama ukuthenga i-resistor yamandla aphezulu mathupha.
Ngale ndlela, ungaqinisekisa ukuthi yinani elilungile futhi wenze ukuhlola okusheshayo ukuze uqinisekise ukuthi azikho izinkinga ngephakheji.
Izinhlobo zama-Resistors zezicelo zamandla aphezulu
Njengoba kushiwo, ama-resistors aphezulu aphezulu asetshenziswa uma udinga ukumelana okwengeziwe kusuka enanini elinikeziwe lamanje.
Kunezinhlobo eziningi zokuphikisa amandla aphezulu, ngayinye yakhelwe izinhlelo zokusebenza ezithile.
Ake sibheke ngokushesha ezinye zezinhlobo ezivame kakhulu.
- I-Carbon Film Resistors I-Carbon film resistors yizici zamandla eziphakeme kakhulu ezitholakalayo.
Lezi resistors zenziwe nge-carbon, into ekwazi ukumelana nokushisa kakhulu.
Ama-resistors amafilimu e-Carbon asetshenziswa ezinhlelweni zamandla aphezulu, njengamandla kagesi nama-amplifiers emoto.
Futhi njengoba enziwe ngekhabhoni, ahlala isikhathi eside kakhulu, okwenza afanelekele izindawo ezinokhahlo.
- I-Metal Film Resistors I-Metal film resistors ifana ne-carbon film resistors ngokwemibandela yokumelana, kodwa inezinga eliphansi lamandla.
Izinqamuleli zefilimu yensimbi zisetshenziswa ezinhlelweni lapho isilinganiso esiphansi sokumelana sibalulekile, njengezisetshenziswa zamandla ezinembayo.
- I-Mixed Resistance Resistors enenhlanganisela yokuphikiswa yizici zamandla aphezulu.
Lezi resistors ngokuvamile inhlanganisela carbon film, ifilimu metal, futhi Ceramic.
Ukumelana okuxubile kuvame ukusetshenziswa ezinhlelweni ezinembayo lapho kudingeka isilinganiso esiphezulu sokumelana, njengamandla kagesi nezinto zokuhlola.
- Ama-Wirewound Resistors Ama-Wirewound resistors asetshenziswa njengezimbangi zamandla aphezulu.
Lawa ma-resistors enziwe ngocingo lwensimbi oluzungeze umgogodla.
Njengezinhlobo ze-resistor ezixubile, ama-wirewound resistors anenhlanganisela yamanani okumelana.
Eleni resistors
Ama-Eleni resistors awuhlobo lwe-resistor yamandla aphezulu eklanyelwe ukuphatha izinhlelo zokusebenza zamandla kagesi aphezulu.
Lawa ma-resistors aklanyelwe ukumelana nama-voltage aphezulu kakhulu futhi ngokuvamile asetshenziswa emigqeni yokudluliswa kwamandla.
Njengoba aklanyelwe ukuphatha ama-voltages adlulele, ngokuvamile anesilinganiso sokumelana eliphezulu.
Ukukhetha I-Resistor Value
Lapho ukhetha i-resistor yamandla aphezulu, udinga ukugcina izinto ezimbalwa engqondweni.
Lokhu kufaka phakathi isilinganiso samandla sesekhethi yakho, i-voltage yesekhethi, kanye nebanga lokumelana lesekethi.
Uma kungenzeka, zama ukucosha umshini wokumelana namandla aphezulu mathupha.
Ngale ndlela, ungaqinisekisa ukuthi yinani elilungile.
Futhi uma ungakwazi, ungasebenzisa ikhithi yokuhlola i-resistor ukuze uhlole amanani we-resistor.
Ungasebenzisa futhi i-voltmeter ukukala i-voltage yesekethe yakho.
Ngale ndlela, ungaqinisekisa ukuthi isekethe idonsa amandla anele ku-resistor.
Ukugoqa i-Resistor nge-Tape noma i-Ceramic
Sonke siyazi ukuthi izinto eziphikisayo ziyashisa uma zisebenza.
Unganciphisa lokhu ngokusebenzisa amasinki okushisa kuma-resistors amandla aphezulu noma ukuwagoqa nge-tape.
Lokhu kwenza i-resistor izinze futhi ivimbele ukuthi ingashisi kakhulu.
Izihlungi zamandla aphezulu ezisongwe ngetheyiphu ngokuvamile zinemizimba ye-ceramic.
Lokhu kungenxa yokuthi i-ceramic ine-conductivity yokushisa enhle kakhulu.
Imvamisa, ungakwazi ukubona ukuthi i-resistor isongwe ngeteyiphu noma nge-ceramic ngoba isitikha esikulebula sizobonisa ukuthi yikuphi.
Ukugoqa I-Resistor nge-Polyethylene Terephthalate (PET) Film
Izinqamuleli zamandla aphezulu ezisongwe ngefilimu ye-PET zivame ukuphikiswa amandla aphezulu afakwa ezintweni zikagesi.
Lezi resistors ngokuvamile inhlanganisela carbon film, ifilimu metal, futhi Ceramic.
Uma ufuna ukuvikela i-resistor yakho yamandla aphezulu emonakalweni, ungayisonga ngefilimu ye-PET.
Lokhu kuzovimbela ukulimala komshini futhi kwenze i-resistor ihlale isikhathi eside.
Isiphetho
High amandla resistors kuyabiza, yingakho ukutshala imali eyodwa akulula.
Nokho, akwenzeki futhi.
Kunezinto eziningi okudingeka uzicabangele ngaphambi kokuthenga isixhasi samandla aphezulu, njengezilinganiso zamandla, ububanzi bokumelana, intengo, njll.
Uma ungenaso isiqiniseko nganoma yikuphi kwalokhu, ungahlala ubuza umdayisi noma uthole ulwazi oluningiliziwe mayelana nezimbangi zamandla aphezulu ku-inthanethi.
