1. Umsebenzi weFuse.
I-fuse yothusa idlala indima ye-fuse kunye nokurhoxisa kumzobo wesekethe, kwaye isetyenziswa ikakhulu kwisekethe isegalelo lesekethe yamandla kunye nesekethe yesekelo lamandla esibini.Ngokuqhelekileyo baxhathisa kakhulu (ii-ohms ezininzi kwi-Ohms) kunye namandla aphantsi (1/8 "1W).
Xa iphoso lesiphatho sesekethe elifutshane lenzeka kumthwalo wesekethe kwaye lwenzeka ngaphezulu, iqondo lobushushu le-fuse liya kuphakama ukuya kuthi ga kwi-500-600 ° C ngexesha elifutshane.Ngeli xesha, umaleko wokugcina umphezulu uya kuncothula ngenxa yobushushu kunye nefuse, edlala indima ye-inshurensi kwaye afezekise ukuphuculwa.Injongo yoKhuseleko lukhuseleko lukhuseleko.
2. Ungawubona njani umphikisi wefuse.
Nangona abaqeqeshekisi basetyenziswa ngokubanzi kwiseketheko elomeleleyo, iindlela zokumakisha kwimizobo yesekethe ziyahluka ukusuka kwilizwe kunye nomenzi.Nangona imiqondiso yelebhile ayikacacanga, ineempawu eziqhelekileyo:
.
.
(3) Mnye kuphela umbala kumthi we-fuse.Njengoko kubonisiwe kumzobo oqhotyoshelweyo, umbala wesangqa semibala ubonakalisa ixabiso lokuchasana.
.
3. Inkcazo nemigangatho eqhelekileyo ye-Fuse.
.Xa i-8.5V DC i-voltage isetyenziswa kuzo zombini iziphelo ze-fuse, ukumelana nokunyuka okungaphezulu kwama-50 ixabiso lokuqala kwimizuzwana engama-60.
.Xa i-3.5a yangoku idlula, ukumelana nokunyuka kwamaxesha angaphezu kwama-50 ixabiso lokuqala kwimizuzwana emi-2.
.Xa i-2.8a idlula i-2.8a i-Ac yangoku, ukumelana nokunyuka kwamaxesha angaphezu kwama-400 ixabiso lokuqala kwimizuzwana eli-10.
