Injongo eyinhloko
Ifuse ifanele ukulayishwa okungaphezulu komugqa kanye nokuvikela isiyingi esifushane kumishini yokusabalalisa impahla kagesi yezimboni ene-AC elinganiselwe imvamisa engu-50Hz, i-voltage elinganiselwe ye-AC ukuya ku-690V, DC 250V kuya ku-440V futhi ilinganiselwe i-cunent ku-1250A.
1.2Uhlobo kanye nencazelo
Uhlobo nokucaciswa
I-Fuse ihlukaniswe ngamasayizi ayisithupha ngokobukhulu be-fuse tube.Usayizi ngamunye unobubanzi bamanje obulinganiselwe obuhambisanayo.Bheka kumapharamitha obuchwepheshe asemqoka wezinga elilinganiselwe le-cun ent le-fuse yosayizi abahlukahlukene.I-fuse ingahlonyiswa nge- impactor ngokuya ngezidingo zomsebenzisi, futhi i- impactor ngokuvamile itholakala ngenhla ngqo kothintana naye.
I-nomenclature yamafuse
Izimo zokusebenza ezijwayelekile
◆Ambient air lokushisa
Izinga lokushisa lomoya we-ambient akumele lidlule ku-40° C, inani elimaphakathi elikalwa emahoreni angu-24 ngeke lidlule ku-35 C, futhi inani elimaphakathi elikalwa ngonyaka owodwa lizoba ngaphansi kwaleli nani.
Izinga lokushisa elincane le-ambient yi-5 C.
◆Ukuphakama
Ukuphakama kwendawo yokufaka akumele kudlule i-2000m.
◆Izimo zomoya
Umswakama wayo ohlobene akumele udlule u-50% ezingeni lokushisa eliphakeme lika-40° C
Umswakama ophezulu ohlobene ungatholakala ezingeni lokushisa eliphansi, isibonelo, kufika ku-90% ku-20C.
Ngaphansi kwalezi zimo, ukuminyanisa okumaphakathi kungase kwenzeke ngengozi ngenxa yokushintsha kwezinga lokushisa.Ngaphandle kokubonisana nomkhiqizi, i-fuse ayikwazi ukufakwa endaweni enenkungu kasawoti noma idiphozi yemboni engajwayelekile.
◆I-Voltage
I-voltage enkulu yesistimu akufanele yeqe u-1 10% wevoltheji ye-fuse elinganiselwe.
Ku-fuse ene-voltage elinganiselwe engu-690V AC kanye no-250V 1440V DC, umkhawulo kagesi wesistimu akufanele udlule u-105% wevolthi elinganiselwe ye-fuse.
Izimo zokufaka ezijwayelekile
◆Isigaba sokufakwa
Isigaba sokufakwa kwefuse yisigaba I.
◆ Izinga lokungcola
Idigri yokunqanda ukungcoliswa kwefuse akufanele ibe ngaphansi kwezinga lesi-3.
◆Imodi yokufaka
I-fuse ingafakwa iqonde phezulu, ivundlile noma igoqekile endaweni yokusebenza ngaphandle kokuzamazama okubalulekile kanye nokudlidliza okunomthelela.
Ibanga lokuphulwa kanye nesigaba sokusebenzisa
Isixhumanisi se-fuse siyisixhumanisi se-fuse esinenjongo evamile kanye nomthamo ogcwele wokuphuka, okungukuthi isixhumanisi se-fuse "gG".
Izici zesakhiwo kanye nesimiso sokusebenza
I-fuse iqukethe isisekelo se-fuse kanye nesixhumanisi se-fuse.Isisekelo se-fuse sakhiwe ngokuthintana kwesisekelo, i-base plate, njll. Isixhumanisi se-fuse sakhiwe ngeshubhu ye-fuse, incibilikisa, isihlabathi se-quartz, ukuthintana kohlobo lommese, njll.
Lapho i-fuse ifakiwe kumjikelezo, lapho i-current edlula i-fuse idlula inani elithile isikhathi esanele, ukuncibilika emzimbeni we-fuse kuzohlanganiswa, futhi i-arc ikhiqizwa lapho i-fuse ihlanganiswa yisihlabathi se-quartz ku-fuse. i-tube izocishwa, ukuze kuzuzwe inhloso yokuphula isifunda.
Lapho ukuncibilika kushaywa, inkomba ekusixhumanisi se-fuse izovela, ebonisa ukuthi isixhumanisi se-fuse sishaywa.
Kufuse efakwe i- impactor, lapho incibilikisiwe ihlanganiswa, i- impactor izophuma ngokuzenzakalelayo.Umsebenzisi udinga kuphela ukufaka i-micro-switch noma idivayisi efanelekile yokuthumela isignali (ekhethiwe futhi ethengwe umsebenzisi) phambi kwe- impactor, bese isignali edingekayo ingatholwa ngemva kokuhlanganiswa kwe-fuse.

5. Ukufakwa, ukusetshenziswa kanye nokugcinwa kwe-fuse
I-fuse izofakwa endlini noma ekhabetheni elingeke lithinteke imvula neqhwa, futhi angeke livezwe futhi lifakwe endaweni okulula ukuthinta.Lapho ufaka i-fuse, qinisekisa ukuthi imvume kagesi inkulu kuno-8 mm futhi ibanga le-creepage likhulu kune-10 mm. Kumjikelezo, indawo yesiphambano sentambo yokuxhuma inconywa njengenani kuThebula lesi-4.

Lapho isixhumanisi se-fuse sishaywa, isixhumanisi se-fuse esisha esinemodeli efanayo, usayizi kanye nesilinganiso samanje njengesixhumanisi sokuqala se-fuse kufanele kushintshwe esikhundleni socingo lwethusi.
Ukushintshwa kwezixhumanisi ze-fuse kuzokwenziwa ngochwepheshe besebenzisa abathwali be-fuse abakhethekile.
Lapho ushintsha isixhumanisi se-fuse, kufanele senziwe ngaphansi kwesimo sokungabi bikho komthwalo, okungcono uma ugesi unqanyulwa.Akuvunyelwe neze ukusebenzisa i-fuse ukunqamula noma ukuxhuma umthwalo lapho kusetshenziswa iswishi.Ngemva kokufaka isixhumanisi se-fuse, qiniseka ukuthi ukuxhumana phakathi kwesixhumanisi se-fuse kanye nokuxhumana okuyisisekelo kuxhumene kahle.
Uma ucisha ukunikezwa kwamandla futhi ushintsha isixhumanisi se-fuse, sicela ususe uthuli nokunye ukungcola kusisekelo se-fuse, ikakhulukazi ukuthintana kwesisekelo, ukuze i-fuse ibe sesimweni esihle sokusebenza.
Ngesikhathi sokusebenza, inkomba yesixhumanisi se-fuse izobhekwa njalo ukuze kutholwe isigaba esisodwa noma ukusebenza kwesigaba esingekho ngesikhathi.
Ukuthutha nokugcinwa kwe-fuse
I-fuse izovikelwa emvuleni naseqhweni ngesikhathi sokuthutha nokugcinwa.Ukuphakama kwamahhala kwe-fuse yebhokisi akumele kube kukhulu kuno-250mm.
Ama-fuse kufanele agcinwe endaweni enomoya ojikelezayo nendawo eyomile, futhi ukuphakama kwama-stacking akumele kudlule izingqimba eziyisithupha.
Ukuqaqa kanye nokuhlolwa kwe-fuse
Ngemva kokukhipha, qala uhlole ukuthi ingabe i-nameplate yefuse iyahambisana yini nohlu lokupakisha kanye nophawu ebhokisini lokupakisha, bese uhlola ukuthi isibophelelo esisekelweni se-fuse noma isixhumanisi se-fuse sikhululekile noma siyawa o比 hlola ukuthi ishubhu le-porcelain isixhumanisi se-fuse siphukile noma siqhekekile, hlola ukuthi isihlabathi se-quartz ku-fuse block siyaphuma, futhi uhlole ukuthi i-fuse icwilisiwe noma ihlaselwe ngamanzi.Uma lezi zimo ezingenhla zitholakala, i-fuse ayikwazi ukusetshenziswa, futhi umenzi uzothintwa kusenesikhathi.
Ibhokisi le-fuse kufanele libe nesitifiketi somkhiqizo, uhlu lokupakisha kanye nemiyalelo yokusebenza.
Imiyalo yoku-oda
Lapho u-oda ama-fuse, imodeli, ukucaciswa, inani kanye nebanga lamanje lezixhumanisi ze-fuse ezihambisanayo kufanele kukhonjiswe.Isisekelo se-fuse nesixhumanisi se-fuse singa-odwa ngokwehlukana.
Kumafuse ezinto ezikhethekile namazinga amanje, kuzothintwa umenzi lapho ku-oda.
