Ama-resistors ane-voltage ephezulu asetshenziselwa ukukhawulela i-voltage ngesekhethi ngenani elithile.
Lokhu kuyasiza ngoba kuvimbela ukulimala kwehardware ebucayi futhi kwenza impilo ibe lula uma usebenza ngama-voltage aphezulu.
Ama-resistors anamandla kagesi aphezulu afika ngamafomethi amaningi ahlukene futhi angasetshenziswa cishe kunoma iyiphi isekethe ye-elekthronikhi.
I-High voltage resistive iyatholakala ngamavelu amaningi ajwayelekile, okuwenza aguquguquke ngokwedlulele ukuze asetshenziswe cishe kulo lonke uhlobo lwedivayisi ye-elekthronikhi.
Zingasetshenziswa futhi njengeziguquli zemvamisa noma njengengxenye yesekethe ye-oscillator.
Ukusetshenziswa okuvame kakhulu kokumelana ne-high-voltage kufaka ukukhawulela ukugeleza kwamanje ngomshini oshisa kakhulu, ukhawule ama-voltage okunikezwa kwamandla, noma ukunikeza ukuvikeleka kumasekhethi amafushane.
Iyini i-High Voltage Resistor?
I-high-voltage resistor iwuhlobo olukhethekile lwe-resistor eklanyelwe ukuphatha ama-voltage aphezulu kakhulu ngokuphepha.
Isibonelo, kukhona ukumelana namandla kagesi aphezulu okukalelwe ukuphatha ama-voltage afika ku-400,000 volts! Lezi zinto eziphikisayo zivame ukukalwa ngama-megohms noma ama-megaohm, kodwa zingatholakala namanye amanani afana nama-megohms angu-10, ama-megohm angu-100, njll.
Kunezinhlobo eziningana ezihlukene zama-resistors angu-voltage aphezulu, ngayinye yakhelwe izinhlobo ezithile zokusetshenziswa nama-voltage.
Ngokudidayo, igama elijwayelekile elithi “high voltage resistor” livame ukusetshenziselwa ukubhekisa kuma-resistor akalwe ngama-voltage aphansi kakhulu kunezinhlobo ezikwazi ukuphatha ama-voltage angaphezu kuka-400,000 volts.
Imisebenzi ye-High Voltage Resistors
– I-Voltage Limiting – I-high voltage resistor isetshenziselwa ukukhawulela i-voltage egeleza kusekethe.
Kunezindlela ezimbili eziyinhloko zokwenza lokhu nge-high-voltage resistor:
- Qondanisa amaVolts -
Uma unesekhethi ethola ukushisa kakhulu, ungasebenzisa i-high-voltage resistor ukukhawulela i-voltage oyithumelayo kudivayisi.
Lokhu kuvame ukwenziwa uma kunikwa amandla umshini wokuthosa njengoba kuzovimbela ukulimala kwehadiwe futhi kuvimbele ihadiwe ekushiseni kakhulu.
- Ukuvikelwa Komhlaba -
Ama-resistors kagesi aphezulu angasetshenziswa ukuvikela isekethe ekufinyezweni.
Ukujikeleza okufushane kwenzeka lapho i-current igeleza emzileni okungafanele ukuthi uqhube umsinga (njengocingo noma i-chassis yedivayisi).
Umphumela uba amandla kagesi angazelele, aphezulu kakhulu angacekela phansi izinto zikagesi noma abangele imililo.
Ukuvikelwa Kuziyingi Ezimfushane Nokushisa Kakhulu
I-high-voltage resistor ivame ukusetshenziselwa ukuvikela izingxenye emonakalweni ovela kumjikelezo omfushane.
Uma idivayisi ifinyezwa kusekethi enamandla kagesi aphezulu egijima kuyo, amandla kagesi aphezulu azobangela ingxenye ukuthi iqhume futhi ibangele ukulimala okubi kakhulu noma ukufa.
Ama-resistors anamandla kagesi aphezulu asetshenziselwa ukuvikela izinto zikagesi ezibucayi kumasekethe amafushane.
Isibonelo, amandla kagesi asebenzisa amandla amaningi kakhulu angase akhiphe i-motherboard noma ezinye izingxenye lapho isifunda esifushane siqedwa.
I-high-voltage resistor isethwe ngokuhambisana nokunikezwa kwamandla, okuvumela i-current ukuthi igeleze ku-resistor esikhundleni sokulimaza izingxenye.
Ama-high-voltage resistors nawo asetshenziswa kuma-oven ama-microwave ukuvikela izingxenye ze-microwave.
Uma isekethe ishisa kakhulu, izingxenye zingashaywa umoya noma zibambe umlilo.
Ngakho-ke i-high-voltage resistor isetshenziselwa ukuvikela izingxenye ezibucayi ekushiseni ngokweqile.
Isifunda se-oscillator sokwenza ukulungiswa kwemvamisa
High-voltage resistors ingasetshenziswa endaweni i-oscillator circuit ukulungisa imvamisa yesignali.
Kumjikelezo we-oscillator, i-voltage yenziwa engxenyeni eyodwa yesifunda, bese iguqulwa futhi ithunyelwe nge-resistor kwenye ingxenye yesifunda.
Lokhu kubangela ukuthi isignali ishintshe imvamisa.
Imvamisa yesiginali ingashintshwa ngokushintsha ukumelana kwe-resistor.
Ukumelana okuphansi kubangela imvamisa ephezulu, kuyilapho ukumelana okuphezulu kubangela imvamisa ephansi.
Ngakho-ke ama-resistors kagesi aphezulu asetshenziswa ukushintsha ukuvama kwesignali.
Ama-resistors kagesi aphezulu angasetshenziswa futhi ukushintsha isivinini se-Arduino noma olunye uhlobo lwebhodi yesilawuli.
Isibonelo, i-high-voltage resistor exhunywe emotweni ingase isetshenziselwe ukusheshisa noma ukunciphisa ukujikeleza kwenjini.
Ukunciphisa Ukunikezwa kwamandla kagesi
High-voltage resistors ziphinde zisetshenziswe kumasekhethi okuphakela amandla ukuze kwehliswe i-voltage ehlinzekwa ezingxenyeni ezibucayi.
Isibonelo, amandla ekhompiyutha ngokuvamile alinganiselwa ku-110 noma 115 volts.
Kodwa-ke, amadivaysi amaningi afana nama-monitor namanye amadivaysi anamandla amakhulu adinga i-voltage eyengeziwe.
Ukunikezwa kwamandla okukalwe ku-110 volts kungenzeka kunganele ukusebenzisa wonke amadivayisi ekhaya lakho.
I-High-voltage resistor ingasetshenziswa ukuguqula i-voltage yokuphakela amandla ibe i-voltage ephezulu.
Isifinyezo
Ama-resistors anamandla kagesi aphezulu asetshenziselwa ukuvikela izingxenye ezizwelayo kumasekhethi amafushane noma ukushisa okudlulele.
Asetshenziswa futhi kumasekhethi okuphakela amandla ukuze anikeze i-voltage eyengeziwe noma ukunciphisa i-voltage.
High-voltage resistors ayatholakala ngamavelu amaningi ajwayelekile, okuwenza aguquguquke ngokwedlulele ukuze asetshenziswe cishe kunoma iyiphi isekethe kagesi.
