Ko chemota fuse chinorebesa hupenyu hwacho sei? Iyo ine simba rekudzivirira kana tembiricha yakanyanyisa? Nhasi, vagadziri vezvigaro zvekuchengetedza motokari vanovaongorora imwe neimwe.

Hupenyu uye inodzivirira mhedzisiro yemotokari fuse inobata

Mukuita kugadzira chigaro chefuse yemotokari, pane zvakanyanya zvigadzirwa zvine nguva shoma yefuse, uye tembiricha yekusungirwa yezvinoda kufanirwa kunofanirwa kutariswa mukusarudzwa kwemagetsi emagetsi module, nekuda kwekusiyana kwekushisa kwayo uye mamakisi akasiyana ezvigadzirwa. . mutengo wayo uchave wakasiyana zvakanyanya, kushandiswa kusina kunaka kuchakanganisa, saka inofanira kunyatsotariswa.

Motokari fuse chigaro chinobuda ripple uye ruzha simba idiki, static care yakanaka, asi yedhipatimendi remagineti kuteterera kwakakwira zvakare, saka fuse chigadzirwa frequency yakaderera pane 300kHz, kunyangwe mamwe angangoita 100kHz, saka zvakaoma kusangana nemutoro. static variables pasi pechikonzero chekuda application, saka unofanirwa kufunga nezve mashandisirwo emhando yepamusoro-frequency switching zvigadzirwa.

Iyo mota inobata fuse inobata mukugadzira ndeyekuti inorebesa hupenyu hwefuse, uye yakagadziridzwa sisitimu yakavimbika ndeyekusarudza yekudzivirira basa chigadzirwa, kureva, yekunze redunhu defect module yefuse, magetsi anogona kuchengetedzwa otomatiki, uye chimiro hachikundikani. Mushure mekuremara kwekunze kwasakara, inofanirwa kukwanisa kudzokera kune yakajairwa otomatiki.

Kudzivirirwa kwefuse yemotokari inobata fuse inofanira kunge ichisanganisira overvoltage, undervoltage, soft start protection, out overvoltage, overcurrent and short circuit protection kana ichishandiswa, uye zvigadzirwa zvayo zvinofanirawo kuva ne overtemperature dziviriro kana zvichishandiswa. chiziviso chikuru cheinotarisirwa inobudirira nguva yekukundikana kwefuse ndiyo njodzi yekunze kukanganisa.

Kazhinji kutaura, fuse current (marked current) inoreva chiyero chezvino chefuse, kureva kuti, fuse inogona kushanda nguva dzose kweanopfuura maawa mana pasina fusing. Iyo yakamisikidzwa ikozvino yeiyo fuse base zvakare yakayerwa ikozvino yeiyo fuse base munzvimbo huru yehoro yebasa, kureva kuti, iyo fuse inogona kuisirwa kwete kupfuura iyo fuse base yakanyorwa ikozvino.

Kupisa mwero we fuse holder

Mukufamba kwekushandisa fuse holder yazvino, kana yazvino ichiyerera nemu conductor, conductor anenge achipisa nekuti pane kumwe kupikisa pakati pemakondakita, uye kukosha kwe calorific yeazvino fuse holder ichatevera Q=024I2RT formula kuti. imwe nhanho, apo T ndiyo nguva yemazuva ano inoyerera kuburikidza nemuitisi, R ndiko kushorwa kwemutyairi, 024 inogara uye Q ndeye calorific value nezvimwe zvakadaro.

Mukati mekugadzira magetsi, fuse yefiyuzi yazvino ichaita kuti tembiricha yekunyungudika ikwire nekuda kwekupisa kunoshandurwa nezvino. Mukuita kurodha yakajairika yekushanda ikozvino kana inobvumirwa overload ikozvino, kupisa kunokonzerwa nezvino uye kupisa kunobudiswa kuburikidza nekunyunguduka, goko uye nharaunda yakapoteredza inogona kuenzaniswa ivo pachavo.

Kana kupisa kwekupisa kweiyo yazvino inobata fuse isingakwanise kuenderana nekumhanya kwekupisa, kupisa uku kunowedzera zvishoma nezvishoma pakunyunguduka, zvichiita kuti tembiricha yekunyunguduka ikwire, uye kana tembiricha yezuva nezuva ichisvika kana kudarika nzvimbo yekunyungudika. , ichaita kuti ive liquefied kana vaporized, nokudaro kubvisa ikozvino uye kudzivirira dunhu uye munhu.

Kuitwa kwemagetsi kweazvino fuse inobata, kana iri kushandiswa, fuse yayo yakabatanidzwa munhevedzano mumagetsi dunhu, kazhinji kutaura, cathode yayo inodiwa kuve diki, kana nzira yacho ichishanda zvakajairika, inongofanana newaya uye inogona. kuitisa dunhu rakadzikama kwenguva yakareba. Kana kuchinja-chinja kwazvino kunoitika nekuda kwekupihwa kwemagetsi kana kupindira kwekunze, inofanirwawo kukwanisa kumira nehumwe huwandu hwekuremerwa. Mune ino fuse inobata, kana paine yakakura yakawanda yakawandisa ikozvino mudunhu, iyo fuse ichaita kuchengetedza kuchengetedzwa kwedunhu nekubvisa ikozvino.

Izvo zviri pamusoro ndiko kuiswa kwe "pamusoro-tembiricha yekudzivirira yemotokari fuse seat". Tinofanira kuziva zvakawanda pamusoro pechigaro chekuchengetedza motokari. Ndapota taura nemugadziri wedu kuti uwane rumwe ruzivo.
