Hauv kev tsim hluav taws xob circuits, fuses ua lub luag haujlwm tseem ceeb heev. Nws tuaj yeem fuse nyob rau hauv qhov kev tshwm sim ntawm tam sim no overload, txiav tawm tam sim no thiab tiv thaiv lwm yam khoom siv tseem ceeb hauv Circuit Court.
Lub fuse muaj peev xwm ua si lub luag haujlwm ntawm kev tiv thaiv lub inverter. Cov khoom siv ntawm lub inverter yog tshwm sim los ntawm ib qho luv luv Circuit Court lossis lwm yam tsis ua haujlwm los ntawm kev sib txuas tsis ncaj ncees lawm ntawm cov xov hlau lossis kev sib txuas rov qab thaum siv thiab ua haujlwm. Ntawm lawv, luv circuits thiab thim rov qab xaim yog qhov feem ntau yuav ua rau muaj kev puas tsuaj rau lub inverter.
Thaum peb siv lub fuse, peb yuav tsum xyuam xim rau cov kev taw qhia ntawm cov xaim, txwv tsis pub nws yuav yooj yim ua rau luv luv ntawm cov khoom siv.
