I-Fuse, evame ukubizwa ngokuthi umshwalense, ingenye yezinto zikagesi ezivikelayo ezilula kakhulu.Lapho okokusebenza kukagesi kugridi yamandla noma ukulayishwa kwesekethe noma isifunda esifushane kwenzeka, kungancibilika futhi kuphule isekethe ngokwayo, kugweme igridi yamandla kanye nokulimala kwemishini kagesi ngenxa yomphumela oshisayo wamandla angaphezu kwamandla kagesi, futhi uvimbele ukusabalala ingozi.
Enye, imodeli ye-fuse
Uhlamvu lokuqala u-R umele ifuse.
Uhlamvu lwesibili u-M lusho ukuthi alukho uhlobo lweshubhu lokupakisha;
U-T usho uhlobo lweshubhu evaliwe;
L kusho ukuvunguza;
U-S umele ifomu elisheshayo;
U-C umele i-porcelain insert;
U-Z umele i-self-duplex.
Okwesithathu ikhodi yokuklama ye-fuse.
Eyesine imelela isilinganiso samanje se-fuse.
Okwesibili, ukuhlukaniswa kwamafuse
Ngokusho kwesakhiwo, ama-fuses angahlukaniswa ngezigaba ezintathu: uhlobo oluvulekile, uhlobo oluvaliwe kanye nohlobo oluvaliwe.
1. Vula uhlobo lwe-fuse
Uma ukuncibilika kungakhawuli i-arc flame kanye nensimbi encibilika izinhlayiya ze-ejection device, kulungele kuphela ukunqamula i-short circuit current akuzona izikhathi ezinkulu, le fuse ivame ukusetshenziswa ngokuhambisana nokushintshwa kommese.
2. I-fuse efakwe kancane
I-fuse ifakwe ku-tube, futhi umkhawulo owodwa noma womabili we-tube uyavulwa.Lapho i-fuse incibilika, i-arc flame nezinhlayiya ezincibilika zensimbi zikhishwa ohlangothini oluthile, okunciphisa ukulimala okuthile kubasebenzi, kodwa namanje akuphephile ngokwanele futhi ukusetshenziswa kunqunyelwe ngezinga elithile.
3. I-fuse evaliwe
I-fuse ivalwe ngokuphelele egobolondweni, ngaphandle kokukhishwa kwe-arc, futhi ngeke ibangele ingozi engxenyeni ebukhoma eseduze ye-arc endizayo kanye nabasebenzi abaseduze.
Okwesithathu, isakhiwo se-fuse
I-fuse ikakhulukazi yakhiwe incibilikisa kanye neshubhu le-fuse noma isibambi se-fuse lapho incibilikisa ifakwa khona.
I-1.I-Melt iyingxenye ebalulekile ye-fuse, evame ukwenziwa usilika noma ishidi.Kunezinhlobo ezimbili zezinto ezincibilikayo, enye isezingeni eliphansi lezinto zokuncibilika, njengomthofu, i-zinc, ithini ne-tin-lead alloy;Enye yizinto ezincibilika kakhulu, njengesiliva nethusi.
I-2.I-melt tube igobolondo elivikelayo lokuncibilika, futhi linomphumela wokucisha i-arc lapho ukuncibilika kuhlanganisiwe.
Okune, amapharamitha we-fuse
Amapharamitha e-fuse abhekisela kumapharamitha we-fuse noma isibambi se-fuse, hhayi amapharamitha wokuncibilika.
1. Ncibilikisa imingcele
I-melt inezinhlaka ezimbili, i-current rated kanye ne-fusing current.Isilinganiso samanje sisho inani lamanje elidlula ku-fuse isikhathi eside ngaphandle kokuphuka.I-fuse current ivamise ukuphinda kabili kuneyamanje elinganiselwe, ngokuvamile ngokuncibilika kwamanje izikhathi ezi-1.3 zamanje ezilinganiselwe, kufanele zihlanganiswe ngaphezu kwehora elilodwa;Izikhathi ezi-1.6, kufanele zihlanganiswe phakathi kwehora elilodwa;Lapho i-fuse current ifinyelelwa, i-fuse iphukile ngemva kwemizuzwana engu-30 ~ 40;Uma izikhathi ezingu-9 ~ 10 umthamo olinganiselwe ufinyelelwa, ukuncibilika kufanele kuphuke ngokushesha.Ukuncibilika kunesici sokuvikela sesikhathi esiphambene, ukukhudlwana kwamanje kugeleza ekuncibilikeni, siba mfishane isikhathi sokuhlanganisa.
2. Imingcele yepayipi yokushisela
I-fuse inamapharamitha amathathu, okuyi-voltage elinganiselwe, amandla amanje akalwe kanye namandla anqamukile.
1) I-voltage elinganiselwe ihlongozwa kusukela ku-Engeli yokucisha i-arc.Lapho i-voltage yokusebenza ye-fuse inkulu kune-voltage elinganiselwe, kungase kube nengozi yokuthi i-arc ayikwazi ukucisha lapho ukuncibilika kuphukile.
2) Isilinganiso samanje seshubhu elincibilikisiwe yinani lamanje elinqunywa izinga lokushisa elivumelekile leshubhu elincibilikisiwe isikhathi eside, ngakho ishubhu elincibilikisiwe lingalayishwa ngamamaki ahlukene wamanje olinganiselwe, kodwa amandla amanje alinganisiwe weshubhu elincibilikisiwe ingabi nkulu kunomthamo okaliwe weshubhu elincibilikisiwe.
3) Umthamo wokusika inani eliphezulu lamanje elinganqanyulwa lapho i-fuse inqanyulwa ephutheni lesekethe ku-voltage elinganiselwe.
Okwesihlanu, isimiso sokusebenza se-fuse
Inqubo yokuhlanganisa ye-fuse icishe ihlukaniswe izigaba ezine:
1. Ukuncibilika kuchungechunge kumjikelezo, futhi umthamo wamanje ugeleza ngokuncibilika.Ngenxa yomphumela oshisayo wamanje uzokwenza izinga lokushisa elincibilikayo likhuphuke, lapho ukulayishwa kwesifunda noma isifunda esifushane kwenzeka, i-overload yamanje noma i-short circuit current izokwenza ukuncibilika kokushisa okukhulu futhi kufinyelele izinga lokushisa elincibilikayo.Lapho izinga lokushisa liphezulu, izinga lokushisa likhuphuka ngokushesha.
2. Incibilika izoncibilika futhi ihwamuke ibe umhwamuko wensimbi ngemva kokufinyelela izinga lokushisa elincibilikayo.Uma uphakeme wamanje, isikhathi sokuncibilika siba sifushane.
3. Lapho incibilika incibilika, kuba khona igebe elincane lokufakwa kumjikelezo, futhi i-current iphazamiseka ngokuzumayo.Kodwa leli gebe elincane lihlehliswa ngokushesha yi-voltage yesifunda, futhi i-arc kagesi ikhiqizwa, yona ixhuma isifunda.
4. Ngemva kokuba i-arc yenzeka, uma amandla ehla, izozicisha ngokwazo ngokwandiswa kwegebe le-fuse, kodwa kufanele incike ezinyathelweni zokucisha ze-fuse lapho amandla amakhulu.Ukuze kuncishiswe isikhathi sokucisha i-arc futhi kwandiswe amandla okuphuka, ama-fuse amakhulu ahlome ngezinyathelo eziphelele zokucisha i-arc.Umthamo wokucisha we-arc mkhulu, i-arc ishesha ukucisha, futhi inkulu i-current circuit short ingaphulwa yi-fuse.
Okwesithupha, ukukhethwa kwe-fuse
1. Khetha amafuse anamazinga kagesi ahambisanayo ngokuya ngegridi yamandla kagesi;
2. Khetha amafuse anamandla okuphuka ahambisanayo ngokuya ngephutha eliphezulu elingase libe khona ohlelweni lokusabalalisa;
3, i-fuse kusekethe yemoto yokuvikela isifunda esifushane, ukuze ugweme injini ngesikhathi sokuqala i-fuse, ngenjini eyodwa, umthamo olinganiselwe wokuncibilika akufanele ube ngaphansi kuka-1.5 ~ 2.5 izikhathi zamanje ezilinganiselwe. yemoto;Kumamotho amaningi, inani lamanje elilinganiselwe lokuncibilika akufanele libe ngaphansi kwezikhathi ezingu-1.5 ~ 2.5 zamanje ezilinganiselwe zenjini yomthamo omkhulu kanye nomthwalo wamanje obaliwe wawo wonke amanye amamotho.
4. Ukuze uthole ukuvikelwa kwe-short-circuit yokukhanyisa noma isithando somlilo kagesi neminye imithwalo, umthamo olinganiselwe wokuncibilika kufanele ulingane noma ube mkhulu kakhulu kunomthamo olinganiselwe womthwalo.
5. Uma usebenzisa amafuse ukuvikela imigqa, amafuse kufanele afakwe emugqeni wesigaba ngasinye.Akuvunyelwe ukufaka ama-fuse emugqeni ongathathi hlangothi kumjikelezo wezintambo ezine-izigaba ezintathu noma ezintathu, ngoba ukuhlukana komugqa ongathathi hlangothi kuzodala ukungalingani kwe-voltage, okungase kushise imishini kagesi.Elayini yesigaba esisodwa esihlinzekwa igridi yomphakathi, amafuse kufanele afakwe emigqeni emaphakathi, ngaphandle kwengqikithi yamafuse egridi.
6. Wonke amazinga amafuse kufanele abambisane lapho esetshenziswa, futhi isilinganiso samanje sokuncibilika kufanele sibe sincane kuneleveli ephezulu.
