Izinhlobo zamafomu: injongo, incazelo, ukumaka

Amafaysi asetshenziswa yonke indawo futhi yonke indawo - asebuchwepheni, kumadivayisi ahlukahlukene kagesi, izimoto, imishini yezimboni. Kunezinhlobo eziningi zalezi zakhi. Ziyini futhi futhi iziphi izici zazo? Ake sicabangele izinhlobo eziyinhloko zamafaysi.

Isici

I-fuse iyigama elijwayelekile elisetshenziswa ngokushelelayo emkhakheni wobunjiniyela kagesi. Le ngxenye ihilela ukuvikelwa kwezintambo, imishini kanye namanethiwekhi kagesi. I-fuse ngumkhiqizo wokushintsha. Iyini injongo yayo? I-fuse iklanyelwe ukuvikela inethiwekhi kagesi kusuka emaphethelweni aphezulu nezifunda ezifushane. Isimiso sokusebenza kwalesi sigaba silula kakhulu - esimweni sokweqile, isici esiklanyelwe ngokukhethekile sichithwa. Ngokuvamile lokhu kuyisixhumanisi se-fuse. Ngakho zonke izinhlobo ze-glass fuses zihlelwe.

Lokhu kufaka kuyisici esibalulekile, ngaphandle kwakho okungenakho uhlobo lwezinto zokuphepha ezingenzeka. Ngaphakathi kwalo kukhona futhi idivayisi ekhethekile ye-arcing. Ukufakwa emafusini kwenziwa nge-porcelain noma imizimba ephathekayo futhi kuhleliwe ezingxenyeni ezikhethekile eziqhuba umbane kagesi. Izinto ezenzelwe ama-currents amancane kungenzeka zingabi nomzimba nhlobo.

I-Fusible

Lezi yizinhlobo ezivame kakhulu zamafomu okusetshenziselwa ukusetshenziswa kwansuku zonke. Mhlawumbe, lokhu okuwukuphela kwento elula ukuhlolisisa impilo. Ukuze wenze lokhu, udinga nje ukubheka imininingwane ekukhanyeni kwelanga - kuyothathwa uma ifomu lokufaka lingasebenzi noma cha. Le mininingwane yenziwa ekwilini lesilazi.

Ifakwe i-ceramic ye-tubular

Lesi sici asifani neze nomkhiqizo weglasi. Umehluko kuphela kulokhu okuvela kuwo umzimba. Kodwa ekusebenzeni lezi zingxenye azihlali zikhululeke - ngeke kwenzeke ukuxilonga "ukukhanya". Ukuze uhlole, udinga ukusebenzisa abahloli noma multimeters.

I-Fusible link LDPE

Lezi zinhlobo ze- fuses zisebenza ngesisekelo somgomo ofanayo. Kodwa lapha umklamo uguqulwa ngendlela yokubona isimo senxenye. Ngakho-ke, uma le nto ishaya, ifulegi elikhethekile lizovela ngemuva komkhiqizo.

Izinto ezinesihlabathi se-quartz

Lezi fuses zibonakala ngezici eziphezulu zokucindezela i-arc. Zikhiqizwa ngezihumusho ezimbili: ku-casing eyenziwe ngezinto zokwakheka noma ngezingilazi zeglasi. Ngokuvamile, umkhiqizo uklanyelwe ukusebenza ngamazinga aphezulu. Kunamamodeli ahamba phambili nakakhulu. Idivayisi ye-fuse inikeza enye imininingwane, efana nokwakhiwa ku-LDPE. Kuyadingeka ukuthi ungathola ukuthi yiyiphi i-fuses ephosayo.

Amafomu okusebenza ngokushesha

Le mikhiqizo ayiyona into ekhethekile kulo lonke. Umehluko kuphela ukuthi lapho kwenzeka isifunda esifushane, ingxenye ye-fusible iyashisa ngokushesha.

SMD

Le mikhiqizo ingatholakala kumadivayisi kagesi. Zincane kakhulu. Isimiso sokusebenza nokuqanjwa kwamafaysi ukuvikela imishini esuka emifuleni ephakeme, engayenza kahle kakhulu.

Ukuziphilisa

Lezi zixazululo ezithakazelisayo. I-fuse yokuphulukisa ngokwengqondo iyingxenye ngaphakathi ngaphakathi eplastiki ekhethekile. Ngesikhathi i-plastic insert ibanda, ingaqhuba ugesi. Lapho nje ukufakwa kufudumele ukushisa okuthile, izakhiwo zayo ezilahlekayo zilahlekile ngokukhuphula ukumelana. Ngemuva kokupholisa, i-wamanje ingaphinde idlule umkhiqizo. Okunye kwalokhu kwaziswa ukuthi ngemuva kokushisa akudingeki ukuba ubeke esikhundleni sento. Imbonini ikhiqiza le mikhiqizo ngezindlela ezahlukene. Zifanele ukugoqa ngokusebenzisa ubuchwepheshe obuphezulu obuphakeme noma obuphezulu. Ngokuvamile, lezi zinhlobo ze-fuses zisetshenziselwa ama-circuits aphansi.

Ukuqhuma

Uma zonke izinto ezingenhla ziyaziwa yiwo wonke umuntu, khona-ke i-fuse fuse iyisiqhema esingavamile. Inqubo yendima evuthayo inikezwa ngomsindo osebenza kahle. Idivayisi ekhethekile yokuqhuma, enamathele engxenyeni ehamba phambili, iqhuma. Izinzwa ezikhethekile zithwale lokhu. Lezi zilandelayo zilandela okwamanje esiteshini kagesi. Lezi fuses eziqondile kakhulu, ngoba zizimele ezizimele zensimbi engxenyeni yokuqhuba. Lesi sici sincike ekunembile kwenzwa yamanje.

Ezinye izinhlobo ze-fuses

Ukuze usebenze kuma-circuits high voltage, i-autogas ekhethekile, imikhiqizo yegesi, kanye nezakhi ze-liquid-type zisetshenzisiwe. Kukhona ngisho namafomu okudubula. Ekuphileni kwansuku zonke azikwazi ukubonwa - lokhu kuyisici esisebenzayo esinamandla.

Ukumaka kanye nezimpawu

Umkhiqizi ngamunye wenza ama-fuses ngaphansi kwekhodi ethile noma i-athikili. Inombolo yocingo ikuvumela ukuba uthole futhi uhlenge imininingwane ezinkampanini. Ngokuvamile, la ma khodi angatholakala kumacala wemikhiqizo. Futhi, ikhodi ingasetshenziswa engxenyeni yensimbi. Ngaphandle kwamakhodi, idatha eyinhloko nayo ingabonakaliswa ezindlini - yilokho okushiwo yi-A, i-voltage elinganisiwe ku-V, ehlukanisa izici noma izici zomklamo. Kusukela kulezi zinsuku kunokwenzeka ukucacisa injongo yefusibha.

Ngakho, inani lamanje elilinganisiwe liyinani eliphakeme elivunyelwe lapho ingxenye ingasebenza khona ngokujwayelekile isikhathi eside.

Iminyango yokuqokwa yimizila evumelekile engavumelekile lapho ingxenye iphumula isifunda ngokuphepha lapho kwenzeka isigamu esifushane noma ngenkathi kunqwabelana kwinethiwekhi.

Ukuphulwa kwamandla kubizwa ngokuthi ama-currents esiphezulu. Ngabo, i-fuse izosebenza, kodwa ukukhishwa kwayo ngeke kubhujiswe.

Isici sithembele isikhathi, lapho i-fuse element ibhujiswe khona okwamanje okugeleza kulokhu. Izinhlobo ezahlukene zefomu ngokusho kwezici ziqoqwe ngokuvumelana nesicelo kanye nesivinini sempendulo. Ngokuvamile lezi zici zibonisa izingxenye zamandla. Ngoba izinhlamvu zamagama ezinhlamvu zesiLatini ziyasetshenziswa. Owokuqala kungukuhlukumeza. Ngakho-ke, uG uhla olugcwele, ingxenye iyakwazi ukuvikela isifunda kokubili kokulayisha futhi okufutshane. A - ububanzi bube yingxenye, futhi izinhlobo ezinjalo zefaysi zivikela kuphela ngama-circuits amafushane.

Incwadi yesibili ichaza izinhlobo zamaketanga:

• I-G iyinkambo yenhloso ejwayelekile.
• L - ukuvikelwa kwezintambo, kanye nezinhlelo zokusabalalisa.
• M - ukuvikelwa kwezikhampasi kumagesi kagesi.
• I-Tr is fuse ekwazi ukuvikela inethiwekhi ye-transformer.

Izinhlamvu ezinezinhlamvu R zisetshenziselwa kanye nemishini yokuzimela amandla. Futhi i-PV inganikeza ukuvikelwa kwamabhethrili elanga.

Ngakho-ke, sihlolisise ukuthi yiziphi izinhlobo zamafaysi okukhona nokuthi yini abhalwe ngayo.
