Ho sa tsotellehe sena le ho eketsoa ha lisebelisoa tse itseng ho fokotsa ho qhoma, moralo oa bona ka kakaretso o ntse o tšoana.
Li-fuse tsa cartridge li ka aroloa ka mekhahlelo e 'meli e eketsehileng; Lifuse tsa motlakase tsa mofuta oa D le li-fuse tsa mofuta oa Link.
Mofuta oa D Cartridge Fuse
Li-fuse tsa mofuta oa D ke mefuta e ka sehloohong ea li-fuse tsa cartridge tse nang le setsi, lesale la adapter, cartridge le fuse cap.
Motheo oa fuse o hokahane le sekoaelo sa fuse mme mohala oa tšepe kapa terata ea jumper e hokahantsoe le setsi sena sa fuse ho phethela potoloho. Li-fuse tsa mofuta oa D hang-hang li emisa phepelo ea motlakase ha hona joale potolohong e feta.
Mofuta oa Khokahanyo/HRC Cartridge Fuse
Li-link kapa high breaking capacity (HRC) li-fuse li sebelisa lihokelo tse peli tsa fuse bakeng sa mochine oa tieho ea nako ts'ireletsong ea overcurrent kapa short circuit. Mofuta ona oa fuse o boetse o bitsoa high breaking capacity (HBC) fuse.
Lihokelo tse peli tsa fusible kapa mekoallo li behiloe ka tsela e tšoanang, e 'ngoe e na le khanyetso e tlase' me e 'ngoe e na le khanyetso e phahameng.
Ha motlakase o feteletseng o sebelisoa ho potoloha, sehokelo se tlase sa ho hanyetsa fusible se qhibiliha hang-hang, ha fuse e phahameng ea ho hanyetsa e tšoara matla a feteletseng ka nako e khutšoanyane. Joale e tla chesa haeba matla a sa fokotsoe ho ea boemong bo amohelehang nakong ena e khutšoanyane ea nako.
Haeba, ho e-na le hoo, sekhahla sa ho robeha se lekantsoeng se hlahisoa hang-hang ha ho na le overcurrent e hlahang potolohong, fuse-link e hanyetsanang haholo e tla qhibiliha hang-hang.
Mefuta ena ea li-fuse tsa motlakase tsa HRC le tsona li sebelisa lintho tse kang phofo ea quartz kapa lino tse sa tsamaisang metsi ho fokotsa kapa ho tima arc ea motlakase. Tabeng ena, li bitsoa li-fuse tsa metsi tsa HRC 'me li tloaelehile mefuteng e phahameng ea motlakase.
Ho na le mefuta e meng ea li-fuse tsa motlakase tsa HRC, tse kang li-bolt-on fuse, tse nang le li-terminals tse atolositsoeng tse nang le masoba, le li-fuse tsa blade, tse sebelisoang haholo tikolohong ea likoloi 'me li na le li-terminals tsa blade ho e-na le li-caps.
Hangata li-fuse tsa blade li na le mokotla oa polasetiki 'me li tlosoa habonolo ho potoloho ha ho e-na le ho se sebetse hantle.
Fuse e ka nkeloang sebaka
Li-fuse tse ka nkeloang sebaka li boetse li bitsoa li-fuse tsa motlakase tse koetsoeng. Li na le likarolo tse peli tse entsoeng ka porcelain; sets'oants'o sa fuse se nang le molamu le setsi sa fuse seo sets'oants'o sena sa fuse se kentsoeng ho sona.
Moqapi oa li-fuse tse senyehang, tse atisang ho sebelisoa libakeng tsa bolulo le tse ling tse tlaase, li etsa hore ho be bonolo ho li tšoara ntle le kotsi ea ho tsosoa ke motlakase. Hangata sets'oants'o sa fuse se na le li-terminals tsa blade le sehokelo sa fuse.
Ha sehokelo sa fusible se qhibiliha, sets'oants'o sa fuse se ka buloa habonolo ho se nkela sebaka. Sets'oants'o sohle se ka nkeloa sebaka habonolo ntle le bothata bofe kapa bofe.
Fuse ea ho otla
Fuse e sebelisa mochine ho itšireletsa khahlanong le li-circuits kapa li-circuits tse khutšoanyane, le ho bontša hore fuse ea motlakase e folile.
Fuze ena e sebetsa ka litefello tse phatlohang kapa ka seliba se koetsoeng le molamu o tsoang ha sehokelo se qhibiliha.
Pini le selemo li bapile le sehokelo sa fusible. Ha sehokelo se qhibiliha, mochine oa ho laolla oa sebetsa, o etsa hore pinana e fofele kantle.
Fetola fuse
Li-switch fuse ke mofuta oa fuse ea motlakase e ka laoloang ka ntle ka ho sebelisa sesebelisoa sa switch.
Lits'ebetsong tse tloaelehileng libakeng tse phahameng tsa motlakase, u laola hore na li-fuse li fetisa matla kapa che ka ho totoba switch hore e be boemong ba ho bulela kapa ho tima.
Fuse e sutumetsang kantle
Li-fuse tse sutumetsang kantle li sebelisa khase ea boron ho fokotsa tšebetso ea arcing. Li sebelisoa libakeng tse phahameng tsa motlakase, haholo-holo ho li-transformer tsa 10 kV.
Ha fuse e qhibiliha, khase ea boron e tima arc 'me e ntšoa ka lesoba la tube.
Koala fuse
Li-fuse ke mofuta oa li-fuse tse hulang moo khokahanyo ea fuse e arohaneng le 'mele oa fuse. Li-fuse tsena li na le likarolo tse peli tse kholo; sekoahelo sa matlo le sets'oants'o sa fuse.
Sets'oants'o sa fuse se na le sehokelo sa fusible, 'me' mele o sehiloeng ke foreimi ea porcelain e ts'ehetsang sets'oants'o sa fuse ka likhokahano tse kaholimo le tse tlase.
Sets'oants'o sa fuse se boetse se ts'oaroa ka lehlakoreng la 'mele o sehiloeng' me sena se etsoa ka lebaka.
Ha sehokelo sa fuse se qhibiliha ka lebaka la ho fetella kapa potoloho e khuts'oane, sets'oants'o sa fuse se hangoa ho tsoa 'meleng oa sehokelo ho sehokelo se kaholimo. Sena se etsa hore e oele tlas'a matla a khoheli, ka hona lebitso "drop fuse".
Sets'oants'o sa fuse se oelang hape ke lets'oao le bonoang la hore fuse e folile mme e hloka ho nkeloa sebaka. Mofuta ona oa fuse o sebelisoa hangata ho sireletsa li-transformer tse tlase tsa motlakase.
Thermal fuse
Fuse ea mocheso e sebelisa matšoao a mocheso le likarolo ho sireletsa khahlanong le overcurrent kapa short circuit. Mofuta ona oa fuse, oo hape o tsejoang ka hore ke sekoahelo sa mocheso 'me o sebelisoa haholo lisebelisoa tse sa utloeng bohloko, o sebelisa motsoako o bobebe joalo ka sehokelo sa fuse.
Ha mocheso o fihla boemong bo sa tloaelehang, sehokelo sa fusible sea qhibiliha ebe se khaola matla likarolong tse ling tsa sesebelisoa. Sena se etsoa haholo-holo ho thibela mollo.
Fuse e ka tsamaisoang bocha
Li-fuse tse ka sebelisoang hape li bitsoa "positive temperature coefficient (PPTC) polymer fuse" kapa "polyfuses" ka bokhutšoanyane, 'me li na le likarolo tse li etsang hore li sebelisoe hape.
Mofuta ona oa fuse o na le polymer ea kristale e sa sebetseng e kopantsoeng le likaroloana tsa khabone tse tsamaisang. Li sebetsa ka mocheso bakeng sa tšireletso ea overcurrent kapa e khutšoanyane ea potoloho.
Ha ho bata, fuse e lula e le boemong ba kristale, e leng ho bolokang likaroloana tsa carbon li le haufi le ho lumella matla ho feta.
Tabeng ea phepelo e feteletseng ea hona joale, fuse e futhumatsa, e fetoha ho tloha ho sebopeho sa kristale ho ea ho boemo bo fokolang ba amorphous.
Likaroloana tsa k'habone joale li arohane haholo, e leng se fokotsang ho phalla ha motlakase. Matla a ntse a phalla ka har'a fuse ena ha e kentsoe tšebetsong, empa hangata a lekanngoa ka mefuta ea milliamp.
Ha potoloho e pholile, boemo ba kristale bo kopanetsoeng ba fuse boa tsosolosoa 'me matla a phalla a sa sitisoe.
Ho sena u ka bona hore li-Polyfuse li hlophisitsoe bocha, ke ka hona lebitso "resettable fuses".
Hangata li fumanoa mehloling ea motlakase ea k’homphieutha le ea thelefono, hammoho le litsamaisong tsa nyutlelie, litsamaisong tsa maeto a lifofane, le litsamaisong tse ling moo ho nkela likarolo tse ling ho tla ipaka ho le thata haholo.
fuse ea semiconductor
Li-fuse tsa semiconductor ke li-fuse tse potlakileng haholo. U li sebelisa ho sireletsa likarolo tsa semiconductor potolohong, joalo ka diode le thyristors, hobane li na le kutloelo-bohloko ho maqhubu a manyane a hona joale.
Li sebelisoa hangata ho li-UPS, li-relay tsa boemo bo tiileng le li-drive tsa makoloi, hammoho le lisebelisoa tse ling le li-circuits tse nang le likarolo tse bonolo tsa semiconductor.
Fuse ea khatello ea surge
Li-fuse tsa ts'ireletso ea surge li sebelisa matšoao a mocheso le lisebelisoa tsa mocheso ho itšireletsa khahlanong le ho phahama ha matla. Mohlala o motle oa sena ke fuse e mpe ea mocheso (NTC).
Li-fuse tsa NTC li kenngoa ka letoto potolohong 'me li fokotsa khanyetso ea tsona ka mocheso o phahameng.
Sena ke se fapaneng hantle le li-fuse tsa PPTC. Nakong ea matla a tlhōrō, khanyetso e fokotsehileng e etsa hore fuse e amohele matla a mangata, e leng ho fokotsa kapa ho "hatella" matla a phallang.
Surface Mount Device Fuse
Li-fuse tsa Surface Mount (SMD) ke li-fuse tse nyane haholo tsa motlakase tse sebelisoang hangata libakeng tse tlase tse nang le sebaka se lekanyelitsoeng. U bona lits'ebetso tsa bona ho lisebelisoa tsa DC joalo ka mehala ea cellular, li-hard drive, le lik'hamera, har'a tse ling.
Li-fuse tsa SMD li boetse li bitsoa chip fuse 'me u ka fumana mefuta e mengata ea hajoale ea tsona.
Hona joale mefuta eohle ea li-fuse e boletsoeng ka holimo e na le litšobotsi tse 'maloa tse eketsehileng tse khethollang boitšoaro ba tsona. Tsena li kenyelletsa matla a hona joale a lekantsoeng, motlakase o lekantsoeng, nako ea ts'ebetso ea fuse, matla a ho robeha le I2T boleng.
