Iifuse zikhusela izixhobo zombane kumbane kwaye zikhusela umonakalo omkhulu obangelwa kukungaphumeleli kwangaphakathi.Ngoko ke, i-fuse nganye inomlinganiselo, kwaye i-fuse iya kuvutha xa i-current idlula ukulinganisa.Xa umsinga usetyenziswa kwifuse ephakathi komsinga oqhelekileyo ongasetyenziswanga kunye nomthamo wokwaphuka olinganisiweyo ochazwe kumgangatho ofanelekileyo, ifyuzi iya kusebenza ngokwanelisayo kwaye ngaphandle kokubeka emngciphekweni okusingqongileyo.
Umsinga olindelekileyo wesiphoso sesekethe apho ifuse ifakelwe khona kufuneka ibe ngaphantsi komlinganiselo wokwaphuka kwamandla akhoyo ochazwe kumgangatho.Ngaphandle koko, xa iphoso lenzeka, i-fuse iya kuqhubeka ibhabha, ivutha, itshise i-fuse, inyibilike kunye noqhagamshelwano, kwaye uphawu lwe-fuse alukwazi ukuqatshelwa.Ngokuqinisekileyo, ukuphulwa kwamandla e-fuse engaphantsi akukwazi ukuhlangabezana neemfuno ezichazwe kumgangatho, kwaye ukusetyenziswa komonakalo ofanayo kuya kwenzeka.
Ukongeza kwi-resistors yokuxubha, kukwakho ne-fuses jikelele, i-thermal fuses kunye ne-self-restoring fuses.Into ekhuselayo idityaniswe ngokubanzi kuthotho lwesekethe, kwisekethe yangoku, ngaphezulu kwe-voltage okanye ubushushu obugqithileyo kunye nezinye izinto ezingaqhelekanga, ziya kuthi zidibanise ngokukhawuleza kwaye zidlale indima yokukhusela, inokuthintela ukwanda ngakumbi kwempazamo.
(1) NgokuqhelekileyoFusebenzisa
Iifusi eziqhelekileyo, ezaziwa ngokuba zii-fuses okanye ii-fuses, zeze-fuses ezingenako ukufunyanwa kwakhona, kwaye zinokutshintshwa kuphela ngee-fuses ezintsha emva kwe-fuses.Iboniswa ngu "F" okanye "FU" kwisekethe.
UlwakhiwoCharacteristics yeCommonFusebenzisa
Iifusi eziqhelekileyo zidla ngokuba neetyhubhu zeglasi, iminqwazi yentsimbi, kunye neefuse.Iminqwazi emibini yentsimbi ibekwe kuzo zombini iziphelo zetyhubhu yeglasi.I-fuse (eyenziwe ngezinto eziphantsi-encibilikayo zetsimbi) ifakwe kwi-tube yeglasi.Ezi ziphelo zimbini zidityaniswe kwimingxuma esembindini yeentsimbi ezimbini ngokulandelelanayo.Xa isetyenziswa, i-fuse ilayishwa kwisitulo sokhuseleko kwaye inokudibaniswa kwichungechunge kunye nesekethe.
Uninzi lweefuse zinomgca, iTV enemibala kuphela, iimonitha zekhompyuter ezisetyenziselwa ukulibazisa iifuse ze-spiral fuses.
EngundoqoPiiameters zeCommonFusebenzisa
Iiparamitha eziphambili zefuse eziqhelekileyo zilinganiswe ngoku, amandla ombane alinganisiweyo, ubushushu be-ambient kunye nesantya sokuphendula.Ireyithingi yangoku, ekwabizwa ngokuba yi-breaking capacity, ibhekisa kwixabiso langoku elinokwaphulwa yi-fuse kwi-voltage elinganisiweyo.Umsebenzi oqhelekileyo osebenzayo we-fuse kufuneka ube ngama-30% ngaphantsi kunomlinganiselo olinganisiweyo.Ukulinganiswa kwangoku kweefuse zasekhaya ngokuqhelekileyo kuphawulwe ngokuthe ngqo kwi-cap yentsimbi, ngelixa i-ring ring ye-fuses ethunyelwa ngaphandle iphawulwe kwi-tube yeglasi.
I-voltage elinganisiweyo ibhekiselele kumbane olawulwa kakhulu we-fuse, eyi-32V, i-125V, i-250V kunye ne-600V inkcazo ezine.Umbane osebenzayo wefuse kufuneka ube ngaphantsi okanye ulingane nexabiso lombane elilinganisiweyo.Ukuba i-voltage yokusebenza ye-fuse idlula i-voltage elinganisiweyo, iya kukhutshwa ngokukhawuleza.
Umthamo wangoku wokuthwala we fuse uvavanywa ku 25℃.Ubomi benkonzo ye-fuses buhambelana ngokuphambene nobushushu be-ambient.Ukuphakama kobushushu be-ambient, kokukhona ubushushu bokusebenza be-fuse, bufutshane ubomi bayo.
Isantya sokuphendula sibhekisa kwisantya apho ifuse iphendula ngayo kwimithwalo eyahlukeneyo yombane.Ngokwesantya sokusabela kunye nokusebenza, iifuse zinokwahlulwa zibe ziindidi zokuphendula eziqhelekileyo, uhlobo lwekhefu lokulibaziseka, uhlobo lwesenzo esikhawulezayo kunye nohlobo lokunciphisa lwangoku.
(2) I-Thermal Fuses
I-fuse ye-Thermal, ekwabizwa ngokuba yi-fuse yeqondo lokushisa, luhlobo lwe-inshurensi yokufudumala engahlawulekiyo, esetyenziswa ngokubanzi kuzo zonke iintlobo ze-cookware yombane, i-motor, i-washing machine, i-fan yombane, i-transformer yamandla kunye nezinye iimveliso zombane.I-fuses ye-Thermal inokohlulwa ibe yindawo ephantsi yokunyibilika ye-alloy ye-thermal fuses, uhlobo lwe-organic compound ye-thermal fuses kunye ne-plastiki-metal fuses ye-thermal ye-thermal ngokuhambelana nemathiriyeli yomzimba yokuvavanya ubushushu.
PhantsiMeltingPioliAuloyiTypeThermalFsebenzisa
Umzimba obona ubushushu bendawo esezantsi yokunyibilika yohlobo lwe-alloy fuse eshushu yenziwe ngoomatshini ukusuka kwi-alloy material enendawo yokunyibilika esisigxina.Xa iqondo lokushisa lifikelela kwindawo yokunyibilika kwe-alloy, umzimba weqondo lokushisa uya kuxutywa ngokuzenzekelayo, kwaye isiphaluka esikhuselekileyo siya kunqunyulwa.Ngokwesakhiwo sayo esahlukileyo, indawo yokunyibilika ephantsi yohlobo lwe-alloy ephantsi yohlobo lwe-alloy ye-alloy uhlobo lwe-fuse eshushu inokohlulwa ibe luhlobo lomxhuzulane, uhlobo loxinzelelo lomphezulu kunye nohlobo lokusabela kwentwasahlobo lwesithathu.
OrganicCompoundTypeThermalFsebenzisa
I-Organic compound thermal fuse yenziwe ngumzimba ova ubushushu, i-electrode ehambayo, intwasahlobo njalo njalo.Umzimba ovavanyayo ubushushu ucutshungulwa kwiikhompawundi zezinto eziphilayo ezinobunyulu obuphezulu kunye noluhlu oluphantsi lobushushu bokuxutywa.Ngokuqhelekileyo, i-electrode ehambayo kunye ne-fixed end point contact, isiphaluka sixhunywe yi-fuse;Xa iqondo lokushisa lifikelela kwindawo yokunyibilika, umzimba weqondo lokushisa udibanisa ngokuzenzekelayo, kwaye i-electrode ehambayo inqanyuliwe ukusuka kwindawo yokuphela kwesigxina phantsi kwesenzo sentwasahlobo, kwaye isiphaluka sinqanyuliwe ukukhusela.
Iplastiki -MokqhubekayoThermalFsebenzisa
Iifuse zeplastiki-zentsimbi ze-thermal zamkela isakhiwo soxinzelelo lwe-surface, kunye nexabiso lokumelana nomzimba weqondo lokushisa liphantse libe ngu-0. Xa ubushushu bokusebenza bufikelela kwiqondo lokushisa elimiselweyo, ixabiso lokumelana nomzimba weqondo lokushisa liya kwanda ngokukhawuleza, lithintele umbane ukuba udlule.
(3) I-Fuse yokuzibuyisela
I-fuse yokubuyisela i-self-restoring fuse luhlobo olutsha lokhuseleko olunomsebenzi ogqithisiweyo kunye nokukhusela ukushisa, onokusetyenziswa ngokuphindaphindiweyo.
UlwakhiwoPrinciple yeSelf -RukugcinaFusebenzisa
I-fuse yokuzibuyisela yi-coefficient ye-PTC ye-thermosensitive element, eyenziwe nge-polymer kunye ne-conductive materials, njl.
Xa isekethe isebenza ngokuqhelekileyo, i-fuse yokubuyisela ivuliwe.Xa kukho i-overcurrent fault in the circuit, ukushisa kwe-fuse ngokwayo kuya kunyuka ngokukhawuleza, kwaye izinto ze-polymeric ziya kungena ngokukhawuleza kwimeko yokumelana nokuphakama emva kokufudumeza, kwaye umqhubi uya kuba yi-insulator, ukunqumla i-current in circuit. kunye nokwenza isiphaluka singene kwimeko yokukhusela.Xa iphoso linyamalala kwaye i-fuse yokuzibuyisela ipholile, ithatha i-conduction state conduction ephantsi kwaye idibanisa ngokuzenzekelayo isiphaluka.
Isantya sokusebenza se-fuse esizibuyiselayo sihambelana nombane ongaqhelekanga kunye nobushushu be-ambient.Inkulu yangoku kwaye iqondo lokushisa liphezulu, ngokukhawuleza isantya sokusebenza siya kuba.
EqhelekileyoSelf -RukugcinaFsebenzisa
I-fuses yokubuyisela i-self-restoring fuses ine-plug-in uhlobo, uhlobo olufakwe phezulu, uhlobo lwe-chip kunye nezinye iimilo zesakhiwo.Iifuse ezisetyenziswa ngokuqhelekileyo ziyi-RGE series, i-RXE series, i-RUE series, i-RUSR series, njl., Ezisetyenziswa kwiikhomputha kunye nezixhobo zombane jikelele.
