Thermal fuse kana thermal cutoff chishandiso chekuchengetedza chinovhura maseketi kurwisa kupisa kwakanyanya.Inoona kupisa kunokonzerwa ne-over-current nekuda kwekupfupika kwedunhu kana kuparara kwechikamu.Thermal fuse haazvigadzirise pachayo kana tembiricha yadonha senge yaizoita circuit breaker.Fuse inopisa inofanira kuchinjwa kana yakundikana kana kuti inokonzerwa.
Kusiyana nemagetsi emagetsi kana macircuit breaker, mafiyuzi anopisa anongobata kune tembiricha yakawandisa, kwete yakawandisa ikozvino, kunze kwekunge yakawandisa ikozvino yakwana kuita kuti fiyuzi inodziya pachayo ichidziye kusvika kune inokonzeresa tembiricha. basa guru, musimboti wekushanda uye nzira yekusarudza mukushandisa kunoshanda.
1. Basa rekupisa fuse
Iyo inopisa fuse inonyanya kuumbwa nefusant, inonyungudika chubhu uye yekunze filler.Kana ichishandiswa, iyo fiyuzi inopisa inogona kunzwa kukwira kwekushisa kwezvigadzirwa zvemagetsi, uye tembiricha inonzwikwa kuburikidza nemuviri mukuru wefiyuzi inopisa uye waya.Kana tembiricha yasvika painonyungudika, fusant inongonyungudika.Kudzvinyirirwa kwepamusoro kwefusant yakanyunguduka kunowedzerwa pasi pekusimudzirwa kwemafirita anokosha, uye fusant inova spherical mushure mekunyunguduka, nekudaro ichicheka dunhu kudzivirira moto.Ita shuwa kushanda kwakachengeteka kwemidziyo yemagetsi yakabatana nedunhu.
2. Kushanda nheyo yefiyuzi inopisa
Sechishandiso chakakosha chekudzivirira kupisa, mafizi anopisa anogona kukamurwazve kuita organic thermal fuse uye alloy thermal fuse.
Pakati pazvo, organic thermal fuse inoumbwa nemovable contact,fusant, and spring.Pamberi pe organic type thermal fuse isati yaitwa, ikozvino inoyerera ichibva kune imwe lead kuburikidza neinofambiswa kusangana uye kuburikidza nesimbi casing kune imwe lead.Kana tembiricha yekunze yasvika payakagadzikwa tembiricha, iyo fusant ye organic matter inonyunguduka, zvichiita kuti iyo compression spring mudziyo isununguke, uye kuwedzera kwechirimo kuchaita kuti iyo inofambiswa yekubata uye rimwe divi rinotungamira riparadzane kubva kune mumwe, uye dunhu riri munzvimbo yakavhurika, wobva wacheka yekubatanidza ikozvino pakati peinofambiswa yekubata uye yedivi inotungamira kuzadzisa chinangwa chekusanganisa.
Alloy type thermal fuse ine waya, fusant, yakakosha musanganiswa, goko uye yekuisa chisimbiso resin.Sezvo tembiricha yakatenderedza (ambient) inokwira, musanganiswa unokosha unotanga kunyungudika.Kana tembiricha yakatenderedza ichiramba ichikwira uye ichisvika pakunyungudika kwefusant, fusant inotanga kunyunguduka, uye pamusoro peiyo alloy yakanyunguduka inoburitsa kushushikana nekuda kwekusimudzirwa kwemusanganiswa unokosha, uchishandisa kushushikana kwepasi uku, iyo yakanyunguduka inopisa chinhu. akapirwa uye akapatsanurwa kumativi maviri, kuti awane chigarire chedunhu chekucheka.Fusible alloy thermal fuses inokwanisa kuseta tembiricha dzakasiyana dzekushanda zvinoenderana nefusant yekuumbwa.
3. Ungasarudza sei fiyuzi inopisa
(1) Iyo yakayerwa tembiricha yekushanda yeyakasarudzwa inopisa fuse inofanirwa kunge iri pasi peiyo tembiricha yekudzivirira giredhi yechinhu chinoshandiswa pamagetsi emagetsi.
(2) Ikozvino yakarongerwa yefuse yakasarudzwa inopisa inofanira kuva ≥ iyo yakawanda yekushanda ikozvino yemidziyo yakadzivirirwa kana zvikamu / ikozvino mushure mekuderedza chiyero.Tichifunga kuti kushanda ikozvino kwedunhu ndeye 1.5A, iyo yakarongwa ikozvino yefuse yakasarudzwa inopisa inofanira kusvika 1.5 / 0.72, kureva, kupfuura 2.0A, kuve nechokwadi chekuvimbika kweiyo thermal fuse fusing performance.
(3) Iyo yakayerwa ikozvino yeyakasarudzwa thermal fuse's fusant inofanirwa kudzivirira iyo yepamusoro ikozvino yemidziyo yakachengetedzwa kana zvikamu.Chete nekugutsa iyi sarudzo inogona kuve nechokwadi kuti iyo inopisa fuse haizove nefusing reaction kana yakajairika peak ikozvino inoitika mudunhu.Kunyanya, kana mota iri muakaisirwa dunhu system inoda kutangwa kazhinji kana braking kuchengetedzwa kuri inodiwa, iyo yakatemerwa ikozvino ye fusant yefuse yakasarudzwa inopisa inofanira kuwedzerwa ne 1 ~ 2 mazinga pamusana pekudzivisa kukwirira kwepamusoro kwechigadzirwa chakachengetedzwa kana chikamu.
(4) Fusant's rated voltage yeyakasarudzwa thermal fuse ichave yakakura kudarika chaiyo yedunhu voltage.
(5) Kudonha kwevoltage yeyakasarudzwa fiyuzi inodziya kunoenderana nezvinodiwa zvetekinoroji zvedunhu rinoshandiswa. Iyi nheyo inogona kufuratirwa mumaseketi emagetsi akakwira, asi pamaseketi emagetsi mashoma, simba rekudonha kwemagetsi pakuita kwefuse rinofanira kuongororwa zvizere. pakusarudza mafizi anopisa nekuti kudonha kwemagetsi kuchakanganisa kushanda kwedunhu.
(6) Chimiro chefusi inopisa inofanira kusarudzwa maererano nechimiro chemudziyo wakadzivirirwa.Semuyenzaniso, mudziyo wakadzivirirwa imota, iyo inowanzoita annular muchimiro, iyo tubular thermal fuse inowanzo sarudzwa uye inoiswa yakananga mugedhi rekoiri kuchengetedza nzvimbo uye kuwana yakanaka tembiricha inonzwa. mudziyo unofanirwa kudzivirirwa ndeye transformer, uye coil yayo indege, sikweya inopisa fiyuzi inofanira kusarudzwa, iyo inogona kuve nechokwadi chekubatana pakati peiyo inopisa fuse uye coil, kuitira kuti iwane kudzivirirwa kuri nani.
4. Chengetedzo pakushandisa thermal fuses
(1) Pane mirau yakajeka uye zvipimo zvemafusi ekupisa maererano neyakayerwa ikozvino, yakayerwa voltage, tembiricha yekushanda, tembiricha ye fusing, tembiricha yepamusoro uye mamwe ma paramita ane hukama, ayo anoda kusarudzwa zviri nyore pasi pechikonzero chekuzadzisa zvinodiwa pamusoro.
(2) Kunyanya kutarisisa kunofanirwa kubhadharwa pakusarudzwa kwekumisikidzwa kweiyo thermal fuse, ndiko kuti, kushushikana kwefiyuzi inopisa hakufanirwe kuendeswa kune fuse nekuda kwesimba rekuchinja kwenzvimbo yezvikamu zvakakosha mu chapera chigadzirwa kana vibration zvinhu, kuitira kuti udzivise zvinokanganisa pakuita kwese kushanda.
(3) Mukushanda kweiyo fiyuzi yekupisa, inofanirwa kuiisa muchiitiko chekuti tembiricha ichiri yakaderera pane yakanyanya kubvumidzwa tembiricha mushure mekunge fuse yaputswa.
(4) Nzvimbo yekuisa yefiyuzi inopisa haisi mumudziyo kana midziyo ine hunyoro hunodarika 95.0%.
(5) Panyaya yekuisa chinzvimbo, iyo thermal fuse inofanirwa kuiswa munzvimbo ine yakanaka induction effect.Panyaya yekumisikidza chimiro, pesvedzero yezvipingamupinyi zvinopisa zvinofanirwa kudzivirirwa zvakanyanya sezvinobvira, Semuyenzaniso, haizove yakananga. yakabatana uye yakaiswa ne hita, kuitira kuti usaendesa kutonhora kwetambo inopisa kune fuse pasi pesimba rekupisa.
(6) Kana iyo fiyuzi inodziya yakabatanidzwa mune parallel kana ichiramba ichikanganiswa ne overvoltage uye overcurrent zvikonzero, iyo isina kujairika huwandu hwemukati ikozvino inogona kukonzera kukuvadzwa kwemukati mekubatana uye kukanganisa zvakaipisisa kushanda kwakajairika kwese kupisa fuse mudziyo.Nokudaro, kushandiswa kwemhando iyi ye fuse device haina kukurudzirwa pasi pemamiriro ezvinhu ari pamusoro apa.
Kunyange zvazvo fuse inopisa ine kuvimbika kwepamusoro mukugadzira, mamiriro asina kunaka ayo fiyuzi imwe chete inopisa inogona kutarisana nayo ishoma, saka dunhu harigoni kugurwa munguva iyo muchina wacho usina kunaka. tembiricha kana muchina wakanyanya kupisa, kana kutadza kushanda kunobata zvakananga muviri wemunhu, kana pasina dunhu rekucheka mudziyo kunze kwefuse, uye kana dhigirii rekuchengetedza rinodiwa.
