Mafusi anochengetedza zvigadzirwa zvemagetsi kubva kumagetsi emagetsi uye kudzivirira kukanganisa kwakakomba kunokonzerwa nekutadza kwemukati. Nokudaro, fuse imwe neimwe ine chiyero, uye fuse inoputika kana ikozvino inodarika chiyero. Kana yazvino yaiswa kufiyuzi iri pakati peyakajairwa isina kusanganiswa uye yakatemerwa yekutyora kwesimba inotsanangurwa muchiyero chakakodzera, fiyuzi ichashanda zvinogutsa uye isingaise mungozi nharaunda yakatenderedza.
Iyo inotarisirwa kukanganisa ikozvino yedunhu panoisirwa fuse inofanira kunge iri shoma pane yakatemerwa yekutyora simba ikozvino inotsanangurwa muchiyero. Zvikasadaro, kana kukanganisa kukaitika, iyo fuse icharamba ichibhururuka, kubatidza, kupisa fuse, kunyungudika pamwe chete nekusangana, uye fuse mucherechedzo haugone kuzivikanwa. Ehe, kutyora kugona kweiyo yakaderera fuse hakugone kuzadzisa zvinodiwa zvakatemwa muyero, uye kushandiswa kwekukuvadza kwakafanana kuchaitika.
Mukuwedzera kune fusing resistors, kunewo mafizi akajairwa, mafizi anopisa uye anozvidzoreredza fuse. Chinhu chekudzivirira chinowanzo batanidzwa munhevedzano mudunhu, iyo inotenderera pamusoro pezvino, pamusoro pevoltage kana kuwandisa uye zvimwe zvisina kujairika chiitiko, inokurumidza fuse uye kuita basa rekudzivirira, inogona kudzivirira kumwe kuwedzera kwechikanganiso.

Mafuse akajairika anowanzo sanganisira machubhu egirazi, makepisi esimbi, uye fuse. Midziyo miviri yesimbi inoiswa kumagumo ese egirazi chubhu. Iyo fuse (yakagadzirwa nesimbi yakaderera-yakanyunguduka) yakaiswa mugirazi chubhu. Iyo miviri migumo yakasungirirwa kumakomba epakati evhavha mbiri dzesimbi zvakateerana. Kana iri kushandiswa, iyo fuse inotakurwa muchigaro chekuchengetedza uye inogona kubatanidzwa munhevedzano nedunhu.

MainPmaaramu eCommonFinoshandisa
Iwo makuru ma paramita eyakajairika fuse akayerwa ikozvino, yakayerwa voltage, ambient tembiricha uye kukurumidza kuita. Yakayerwa ikozvino, inozivikanwawo sekutyora simba, inoreva kukosha kwazvino uko fuse inogona kupaza payakayerwa voltage. Iyo yakajairika yekushanda ikozvino yefuse inofanira kunge iri 30% yakaderera pane yakatarwa ikozvino. Kuyerwa kwazvino kwemafuse emumba kunowanzo kunyorwa zvakananga pane kepisi yesimbi, nepo mhete yemavara yemafusi anounzwa kunze inotarwa pachubhu yegirazi.
Rated voltage inoreva yakanyanya kudzorwa voltage yefuse, iyo 32V, 125V, 250V uye 600V ina yakatarwa. Iyo chaiyo yekushanda voltage yefuse inofanira kunge yakaderera pane kana kuenzana neyakatemerwa voltage kukosha. Kana simba rekushanda re fuse rinodarika chiyero chemagetsi, chichakurumidza kuputika.
Ikozvino kutakura kugona kwefuse kunoedzwa pa25 ℃. Hupenyu hwesevhisi hwemafuse hwakapesana netembiricha yepakati. Iyo yakakwirira ye ambient tembiricha, iyo yakakwirira tembiricha yekushanda ye fuse, iyo ipfupi hupenyu hwayo.
Nhanho yekupindura inoreva kumhanya uko fuse inopindura kune akasiyana mitoro yemagetsi. Zvinoenderana nekumhanya kwekuita uye kuita, fuse inogona kukamurwa kuita yakajairwa mhinduro mhando, kunonoka break type, yekukurumidza chiito mhando uye yazvino yekumisa mhando.
(2) Thermal Fuses
Thermal fuse, inozivikanwawo setembiricha fuse, imhando yeinishuwarenzi isinga gadziriswe, inoshandiswa zvakanyanya mumhando dzese dzemagetsi cookware, mota, muchina wekuwachisa, feni yemagetsi, shanduko yemagetsi uye zvimwe zvigadzirwa zvemagetsi. Thermal fuse inogona kupatsanurwa kuita yakaderera melting point alloy type thermal fuse, organic compound type thermal fuse uye epurasitiki-simbi mhando yemafuta fuse zvinoenderana neyakasiyana tembiricha inonzwa zvinhu zvemuviri.

Iyo tembiricha inonzwa muviri weyakadzika melting point alloy mhando inopisa fuse inogadzirwa kubva kune alloy zvinhu zvine yakagadziriswa nzvimbo yekunyungudika. Kana tembiricha yasvika painonyungudika yealloy, iyo tembiricha inonzwa muviri inosanganiswa yega, uye dunhu rakachengetedzwa rinobviswa. Zvinoenderana neyakasiyana magadzirirwo ayo, yakaderera melting point alloy mhando inopisa yakaderera melting point alloy mhando inopisa fuse inogona kukamurwa kuita giravhiti mhando, pamusoro tension mhando uye chitubu chekuita rudzi rwechitatu.
OrganicCompoundTypeThermalFuse
Organic compound thermal fuse inoumbwa nemuviri unonzwa tembiricha, inofambiswa electrode, chitubu zvichingodaro. Tembiricha inonzwa muviri inogadziriswa kubva kune organic komisheni ine kuchena kwakanyanya uye yakaderera fusing tembiricha. Kazhinji, iyo inofambiswa electrode uye yakagadziriswa yekupedzisira point contact, dunhu rakabatana nefuse; Kana tembiricha yasvika painonyungudika, tembiricha inonzwa muviri inozvibatanidza, uye iyo inofambiswa electrode inobviswa kubva payakagadziriswa magumo pasi pechiito chechirimo, uye dunhu rinobviswa kuti ridzivirire.
Plastiki -MetalThermalFuse
Plastic-metal thermal fuses inotora chimiro chekushushikana kwepamusoro, uye kukosha kwekudzivirira kwemuviri wekushisa unonzwa kunenge 0. Kana kupisa kwekushanda kunosvika pakupisa kwakagadzirirwa, kukosha kwekudzivirira kwemuviri wekushisa kunonzwa kuchawedzera kamwe kamwe, kudzivirira ikozvino kubva kudarika.
(3) Kuzvidzorera Fuse
Kuzvidzorera fuse rudzi rutsva rwekuchengetedza chinhu chine overcurrent uye overheat kudzivirira basa, iro rinogona kushandiswa kakawanda.
StructuralPrinciple ofSelf -RkuchengetedzaFinoshandisa
Kuzvidzoreredza fuse ndeye yakanaka tembiricha coefficient PTC thermosensitive element, yakagadzirwa nepolymer uye conductive zvinhu, nezvimwewo, iri munhevedzano mudunhu, inogona kutsiva yechinyakare fuse.
Kana dunhu riri kushanda zvakajairika, iyo yekuzvidzoreredza fuse iripo. Kana paine kukanganisa kwakanyanya mudunhu, tembiricha yefuse pachayo ichakwira nekukurumidza, uye iyo polymeric zvinhu zvichakurumidza kupinda munzvimbo yakakwirira yekupikisa mushure mekupisa, uye conductor ichava insulator, ichicheka ikozvino mudunhu. uye kuita kuti dunhu ripinde munzvimbo yekudzivirira. Kana kukanganisa kuchinyangarika uye fuse inodzoreredza inotonhorera pasi, inotora yakaderera kupikisa conduction state uye inongobatanidza dunhu.
Iyo yekumhanyisa yekushanda kweiyo yekuzvidzoreredza fuse ine hukama neiyo abnormal ikozvino uye ambient tembiricha. Iyo yakakura ikozvino uye yakakwirira tembiricha iri, iyo inokurumidza kukurumidza kukurumidza kushanda.
