Sumo yefuyuzi yesimba

Nheyo yefuyuzi yesimba

Fuse yemagetsi ndeimwe yemafuse, zvinoreva mudziyo wemagetsi unobatanidza kunyunguduka nekupisa kunokonzerwa nega uye unobvisa dunhu kana magetsi adarika kukosha kwakatarwa. Fuse iyi inodzivirira magetsi anoshandiswa nekushandisa kupisa kunobva kwaga kunyungudutsa kunyunguduka mushure mekunge magetsi adarika kukosha kwakatarwa kwenguva yakati, nokudaro zvichibvisa dunhu.

Musimboti wekushanda kwefuse iI2R iri nyore kana tichienzanisa nenguva. Kana magetsi akakwira, nguva yekusanganisa kana yekuvhura ipfupi. Kupararira kwesimba refuse kunoenderana neskweya yemagetsi kuburikidza nefuse. Kana simba rakawanda, fuse inoputika. Ichi chinhu chinoshandawo kune mahaneti akachengetedzwa nefuse. Kana kupisa kunokonzerwa kwakapfuura kupisa kwakadzimwa, tembiricha yefuse ichawedzera. Kana tembiricha yakwira kusvika pakunyunguduka kwefuse yefuse, fuse ichaputika, kureva kuti, circuit ichabviswa kuti dzivirirwe.

Mafusi anoshandiswa zvakanyanya mumasisitimu ekugovera simba remagetsi ane simba rakawanda nerakaderera pamwe nemasisitimu ekudzora pamwe chete nemidziyo yemagetsi. Semudziviriri wemagetsi mapfupi uye overcurrent, ndeimwe yemidziyo yekudzivirira inonyanya kushandiswa.

Kupatsanurwa kwemafuyusi emagetsi

Mafusi emagetsi chikamu chemafusi (mafusi), anogona kukamurwa kuita mafusi ekudzivirira esemiconductor, mafusi eDC, mafusi akakosha, mafusi anoshandiswa zvakanyanya uye madisconnector efusi.

Hunhu hwechimiro chefuse yesimba

Maumbirwo efuse yesimba akafanana neaya efuse. Inonyanya kuumbwa nekunyunguduka, goko uye rutsigiro, pakati pazvo kunyunguduka ndiko chinhu chakakosha kudzora hunhu hwekubatanidza. Zvinhu, saizi uye chimiro chekunyunguduka zvinosarudza hunhu hwekubatanidza. Zvinhu zvakanyunguduka zvakakamurwa muzvikamu zviviri: nzvimbo yekunyunguduka yakaderera nenzvimbo yekunyunguduka yakakwirira. Zvinhu zvine nzvimbo yekunyunguduka yakaderera zvakaita se lead ne lead alloys zvine nzvimbo yekunyunguduka yakaderera uye zviri nyore kubatanidza. Nekuda kwekudzivirira kwazvo kukuru, saizi yekunyunguduka yakakura, uye utsi hwakawanda hwesimbi hunogadzirwa panguva yekubatanidza. Inokodzera chete kubatanidza ine simba shoma rekupwanya. Zvinhu zvine nzvimbo yekunyunguduka yakakwirira zvakaita semhangura nesirivha zvine nzvimbo yekunyunguduka yakakwirira uye hazvisi nyore kubatanidza, asi nekuda kwekudzivirira kwavo kwakaderera, zvinogona kugadzirwa kuita zvikamu zvidiki pane nzvimbo yekunyunguduka yakaderera, uye zvinogadzira utsi hwesimbi hushoma kana hwasanganiswa, izvo zvakakodzera nzvimbo dzekupwanya dzakakwirira. Chimiro chekunyunguduka chakakamurwa kuita mhando mbiri: filament neribhoni. Kuchinja chimiro chechikamu chinoshanduka kunogona kuchinja zvakanyanya hunhu hwekubatanidza fuse.
