Uhlolojikelele
I-drop fuse kanye ne-load switch fuse ngamadivayisi angaphandle avikela amandla kagesi aphezulu.Zixhunywe kulayini ongenayo noma umugqa wokusabalalisa we-transformer yokusabalalisa.Lezi zisetshenziselwa ikakhulukazi ukuvikela ama-transformer noma imigqa kusuka kumjikelezo omfushane, ukulayisha ngokweqile nokushintsha kwamandla.I-drop fuse iqukethe i-insulator kanye neshubhu ye-fuse.Oxhumana nabo abamile bagxilile ezinhlangothini zombili zobakaki wesivikelo, futhi othintana nabo abahambayo bafakwa kuzo zombili iziphetho zeshubhu ye-fuse.Ngaphakathi kweshubhu ye-fuse kunepayipi lomlilo.Ingaphandle yenziwe nge-phenolic composite paper tube noma ingilazi ye-epoxy.I-fuse yokushintsha ukulayisha inikeza ukuthintana okuyisizayo okunwetshiwe kanye nokuvalwa kwegumbi lokucisha i-arc ukuze uvule/uvale umthwalo wamanje.
Ngesikhathi sokusebenza okujwayelekile, i-fuse idonselwa endaweni evaliwe.Ngaphansi kwezimo zamanje ezinephutha, isixhumanisi se-fuse siyancibilika futhi sakhe i-arc.Lesi yisimo segumbi lokucima i-arc.Lokhu kudala ukucindezela okuphezulu eshubhu futhi kubangela ukuthi ishubhu lihlukane noxhumana nabo.Uma i-fuse incibilika, amandla othintana nabo azokhululeka.I-circuit breaker manje isisendaweni evulekile futhi u-opharetha udinga ukuvala okwamanje.Othintana nabo abanyakazayo bangadonswa kusetshenziswa izinsimbi ezifakwe i-insulated.Othintana naye oyinhloko nomsizi kuxhunyiwe.

(1) Ukuze kwenziwe ifyuzi isebenze ngokuthembekile nangokuphepha, ngaphezu kokukhetha ngokuqinile imikhiqizo nezinsiza ezifanelekile (kuhlanganise nezingxenye ezifuse) ezikhiqizwe abakhiqizi abasemthethweni ngokwezidingo zemithethonqubo, lezi zindaba ezilandelayo zizonakwa ngokukhethekile. ekuphathweni kokusebenza nokulungiswa:
① Hlola ukuthi ingabe umthamo wamanje olinganiselwe we-fuse ufana yini nokuncibilika futhi ulayishe amanani amanje ngendlela efanele.Uma ukufanisa kungalungile, kufanele kulungiswe.
② Ukusebenza ngakunye kwefuse kufanele kucophelele futhi kucophelele, kungabi budedengu, ikakhulukazi ukuvala.Oxhumana nabo abaguqukayo nabamile kufanele baxhumane kahle.
③ Ukuncibilika okujwayelekile kufanele kusetshenziswe epayipini elincibilikayo.Akuvunyelwe ukusebenzisa intambo yethusi ne-aluminium esikhundleni sokuncibilika, futhi akuvunyelwe ukusebenzisa intambo yethusi, i-aluminium nentambo yensimbi ukubopha othintana naye.
④ Kumafuse asanda kufakwa noma ashintshiwe, inqubo yokwamukela izokwenziwa ngokuqinile, futhi izimfuneko zekhwalithi zemithetho kufanele zihlangatshezwe.I-angle yokufaka ye-tube fuse izofinyelela cishe ku-25 °.
⑤ Ukuncibilika okuhlanganisiwe kuzoshintshwa kufakwe entsha yezimpawu ezifanayo.Akuvunyelwe ukuxhuma i-fused melt bese uyifaka ku-tube yokuncibilika ukuze isetshenziswe ngokuqhubekayo.
⑥ I-fuse kufanele ihlolwe njalo, okungenani kanye ngenyanga ebusuku, ukuze kubhekwe ukuthi ayikho yini inhlansi ephumayo kanye nokuthintwa kabi.Uma kuphuma ukukhishwa, kuzoba nomsindo wokuhayiza, okufanele kusingathwe ngokushesha ngangokunokwenzeka.
(2) Lokhu kuhlolwa okulandelayo kuzokwenziwa ukuze kusetshenziswe amafuse ngesikhathi sokuhlolwa kwentwasahlobo kanye nokulungiswa kokucisha:
① Ukuthi ukuthintana phakathi kokuthintana okumile nokunyakazayo kuyahambisana, kuqinile futhi kuqinile, kanye nokuthi lukhona yini uphawu lokusha.
② Ukuthi izingxenye ezijikelezayo zefuse ziyaguquguquka, ziyagqwala, aziguquki, njll., noma ngabe izingxenye zonakele, nokuthi intwasahlobo igqwalile.
③ Ukuthi inyibiliki ngokwayo yonakele noma cha, nokuthi ingabe kukhona ukushisisa okude okweqile futhi iba buthaka ngemva kokukhanyisa amandla esikhathi eside.
④ Ukuthi ishubhu lokucindezela i-arc lokukhiqiza igesi kushubhu elincibilikayo liyashiswa, lonakaliswe futhi likhubazekile ngemva kokuchayeka elangeni nasemvuleni, nokuthi ubude buyafinyezwa yini ngemva kwezenzo eziningi.
⑤ Hlanza isivikelo futhi uhlole ukuthi kukhona umonakalo, ukuqhekeka noma umkhondo wokuphuma.Ngemva kokukhipha umkhondo ongaphezulu nophansi, sebenzisa i-megger engu-2500V ukuze uhlole ukumelana nokwahlukanisa, okufanele kube kukhulu kuno-300M Ω.
⑥ Hlola ukuthi imikhondo yokuxhuma engenhla nangaphansi ye-fuse ikhululekile, ikhishiwe noma ishisa ngokweqile.
Amaphutha atholakala kulezi zinto ezingenhla kufanele alungiswe ngokucophelela futhi asingathwe.
Ukuncibilika kwe-tube structure:
I-fuse yenziwe nge-flberglsaa, engumswakama futhi imelana nokugqwala.
Isisekelo se-Fuse:
Isisekelo somkhiqizo sihlanganiswe nezakhiwo zemishini nama-insulators.Indlela yensimbi yensimbi ifakwe ngezinto ezikhethekile zokunamathela kanye ne-insulator, engakwazi ukumelana namanje wesifunda esifushane ukuze uvule amandla.
I-fuse-proof fuse ayinawo amabhamuza, ayikho i-deformation, ayikho isifunda esivulekile, umthamo omkhulu, i-anti-ultraviolet, impilo ende, izakhiwo zikagesi eziphakeme, amandla e-dielectric kanye nokuqina okuhle kakhulu kwemishini kanye nekhono lokuzinikela.
Yonke imishini ayithathi hlangothi, kulula ukuyifaka, iphephile futhi inokwethenjelwa.
