Incazelo Yomkhiqizo

Amafuse aphumayo ochungechunge lwe-RW12F ayizinto zikagesi zangaphandle ezivikela amandla kagesi aphezulu kumasistimu okudlulisa amandla nokusabalalisa.Zifakwe ohlangothini lwe-high-voltage lwe-transformers yokusabalalisa noma emigqeni yegatsha yemigqa yokusabalalisa, futhi zisetshenziselwa ukuvikelwa kwe-short-circuit kanye nokulayisha ngokweqile kwama-transformers nemigqa, kanye nokuhlukaniswa nokuhlanganisa imisinga yomthwalo.I-fuse ye-ceramic drop-out ene-voltage ephezulu yenziwe ngabakaki be-ceramic insulating kanye neshubhu ye-fuse.I-static contact ifakwe kuzo zombili iziphetho zebakaki le-insulating, futhi okuthintwayo okunyakazayo kufakwe kuzo zombili iziphetho zeshubhu ye-fuse.Ishubhu ye-fuse yakhiwe ngeshubhu yokucindezela i-arc yangaphakathi kanye neshubhu ye-fuse.Isendlalelo sangaphandle sakhiwe ngeshubhu lephepha le-phenolic noma ishubhu yendwangu yengilazi ye-epoxy.I-fuse yohlobo lokwehlisa umthwalo ithuthukisa ukuthintana okuyisiza okunwebekayo kanye nekhava yokucisha i-arc ukuze ihlukanise futhi ihlanganise umthwalo wamanje.

Izici zeSakhiwo somkhiqizo kanye nobubanzi bokusetshenziswa

Melt tube structure:
I-Fuse take eyenziwe nge-flberglsaa, ingangenwa amanzi kanye ne-corrosion-proof.
Isisekelo se-Fuse:
Isisekelo somkhiqizo esishumekiwe isakhiwo semishini kanye nesivikelo.Faka umshini wensimbi yensimbi usebenzisa izinto ezikhethekile zokuhlanganisa nesivikelo ndawonye , ungavula amandla kagesi ngokuma kwesiyingi esifushane.
I-fuse engenamanzi ayinamabhamuza, i-deformation, ivulekile, umthamo omkhulu, i-UV, impilo ende, izakhiwo zikagesi eziphakeme, amandla e-dielectric kanye nokuqina okuhle kakhulu kwemishini kanye nekhono elingcwele.
Inhlangano yonke ukungathathi hlangothi, ukufakwa okulula, okuphephile nokuthembekile.
1. Izinga lokushisa le-ambient alikho ngaphezu kuka-+40 C, hhayi ngaphansi kuka-40 C
2. Ukuphakama akudluli ku-3000m
3.Isivinini somoya esiphezulu asidluli ku-35m/s
4. Izinga lokuzamazama komhlaba lingeqi ku-8 degrees

Ukufakwa kwe-Fuse nokusebenza

1. Ukufakwa kwe-drop fuse:
(1) Ukuncibilika kufanele kuqiniswe ngesikhathi sokufakwa (ukuze ukuncibilika kube ngaphansi kwamandla aqinile angaba ngu-24.5N), ngaphandle kwalokho kulula ukubangela ukuthi othintana naye ashise kakhulu.
(2) I-fuse efakwe engalweni yesiphambano (uhlaka) kufanele iqine futhi ithembeke, futhi akufanele kube nokunyakaziswa noma ukunyakaziswa.
(3) Ishubhu elincibilikayo kufanele libe ne-engeli yokuthambekela eya phansi engu-25°±2°, ukuze ishubhu elincibilikayo likwazi ukuwa ngokushesha ngesisindo salo lapho ukuncibilika kuphephuka.
(4) I-fuse kufanele ifakwe engalweni ephambene (uhlaka) ngebanga eliqondile elingekho ngaphansi kwama-4m ukusuka phansi.Uma ifakwe ngaphezu kwe-transformer yokusabalalisa, kufanele igcine ibanga elivundlile elingaphezu kuka-0.5m ukusuka emngceleni wekhonta wangaphandle we-transformer yokusabalalisa.Ukuwa kweshubhu elincibilikayo kwadala ezinye izingozi.
(5) Ubude beshubhu ye-fuse kufanele bulungiswe ngokusesilinganisweni.Kudingeka ukuthi ulimi lwe-duckbill lungabamba ngaphezu kwezingxenye ezimbili kwezintathu zobude bokuthintwa ngemva kokuvala, ukuze kugwenywe ukusetshenziswa kabi kokuziwisa ngesikhathi sokusebenza, futhi ishubhu ye-fuse akufanele ishaye ibhilidi., ukuze kuvinjwe ithubhu elincibilikayo ukuba lingawi ngesikhathi ngemva kokuncibilika kushaywa.
(6) Ukuncibilika okusetshenzisiwe kufanele kube umkhiqizo ojwayelekile womkhiqizi ojwayelekile, futhi ube namandla athile emishini.Ngokuvamile, ukuncibilika kuyadingeka ukuze kumelane namandla aqinile angaphezu kuka-147N.
(7) I-10kV drop-out fuse ifakwe ngaphandle, futhi ibanga eliphakathi kwezigaba liyadingeka ukuba libe likhulu kuno-70cm.
Okwesibili, ukusebenza kwe-fuse yokudonsa:
Ngaphansi kwezimo ezijwayelekile, akuvunyelwe ukusebenzisa i-fuse yokudonsa ngomthwalo, kuphela kuvunyelwe ukusebenzisa imishini engekho (umugqa).Kodwa-ke, imigqa yegatsha yemigqa yokusabalalisa engu-10kV kumagridi kagesi asemaphandleni kanye nama-transformer okusabalalisa anomthamo olinganiselwe ongaphansi kuka-200kVA avunyelwe ukusebenza nomthwalo ngokuya ngalezi zidingo ezilandelayo:
(1) Lo msebenzi uzokwenziwa abantu ababili (oyedwa ozogada nomunye ozosebenza), kodwa kufanele agqoke amagilavu avikelayo, amabhuzu avikelayo, kanye nezibuko, futhi asebenze ngezinti ezifanelekayo ezifaka amazinga kagesi afanayo.Umsebenzi awuvunyelwe emvuleni enkulu.
(2) Ngesikhathi sokusebenza kwesango, ngokuvamile kushiwo ukuthi isigaba esiphakathi sidonswa kuqala, bese sidonswa isigaba se-leeward side, bese kuthi isigaba esisohlangothini somoya sidonswe.Lokhu kungenxa yokuthi i-transformer yokusabalalisa ishintshiwe kusukela ekusebenzeni kwezigaba ezintathu kuya ekusebenzeni kwezigaba ezimbili, futhi i-arc spark ekhiqizwa lapho isigaba esiphakathi siphukile sincane, esingeke sibangele isifunda esifushane phakathi kwezigaba.Okwesibili ukuphula isigaba se-leeward side, ngoba isigaba esiphakathi sikhishwe sahlukaniswa, futhi ibanga phakathi kwesigaba se-leeward side kanye ne-windward side phase liphindwe kabili.Ngisho noma kukhona i-overvoltage, kungenzeka ukuthi isifunda esifushane phakathi kwezigaba sincane kakhulu.Uma ingxenye eseceleni evunguzayo ihlehliswa emuva, kuba khona i-capacitive current kuphela phansi, futhi inhlansi ekhiqizwayo iba incane kakhulu.
(3) Lapho uvala, ukulandelana kokusebenza kuyahlehliswa lapho kuvalwa, qala ngokuvala isigaba esibheke komoya, bese uvala isigaba se-leeward, bese uvala isigaba esimaphakathi.
(4) Ukusebenzisa ishubhu elincibilikayo kuyinto evamile.Uma unganaki, kuzokwenza ukuthi othintana naye ashise futhi kubangele ukuthintana okungalungile, kushise kakhulu othintana naye, futhi kuqede intwasahlobo, okuzokwenza othintana naye abe mubi kakhulu futhi akhe umbuthano ononya.Ngakho-ke, lapho udonsa futhi uvala i-fusion tube, sebenzisa amandla aphakathi.Ngemva kokuvala, hlola ngokucophelela ukuthi ulimi lwe-duckbill lungaboshelwa ngokuqinile ngaphezu kwezingxenye ezimbili kwezintathu zobude bolimi.Ungasebenzisa i-lever yebhuleki ukuxhuma i-duckbill engenhla bese ucindezela phansi izikhathi ezimbalwa.Zama ukudonsa futhi ukuze uhlole ukuthi ilingana kahle yini.Uma iswishi ivaliwe, ayikho endaweni noma ayivalwanga ngokuqinile, futhi ukucindezela kokuxhumana okumile ku-fuse ayanele, okungabangela kalula ukuthi lowo othintana naye ashise noma ishubhu le-fuse liwele ngokwalo.
