CJPV1451B 14X51 32A 1000VDC fuse base Solar Photovoltaic PV Fuse ndi Fuse Holder

Fuse ya DC ndi chipangizo chomwe chimapangidwa kuti chiteteze ma circuit amagetsi ku kuwonongeka komwe kumachitika chifukwa cha mphamvu yamagetsi yochulukirapo, yomwe nthawi zambiri imachitika chifukwa cha kuchuluka kwa magetsi kapena kufupika kwa magetsi. Ndi mtundu wa chipangizo chotetezera magetsi chomwe chimagwiritsidwa ntchito mumakina amagetsi a DC (direct current) kuti chiteteze ku ma circuit amagetsi ochulukirapo komanso afupi.

Ma fuse a DC ali ofanana ndi ma fuse a AC, koma amapangidwira kuti azigwiritsidwa ntchito m'ma circuits a DC. Nthawi zambiri amapangidwa ndi chitsulo choyendetsa kapena alloy chomwe chimapangidwa kuti chisungunuke ndikusokoneza dera pamene magetsi apitirira mulingo winawake. Fuse ili ndi mzere woonda kapena waya womwe umagwira ntchito ngati chinthu choyendetsa, chomwe chimagwiridwa ndi kapangidwe kothandizira ndikutsekedwa mu kabokosi koteteza. Pamene magetsi akuyenda kudzera mu fuse apitirira mtengo wovomerezeka, chinthu choyendetsa chimatentha kenako chimasungunuka, ndikuswa dera ndikusokoneza kuyenda kwa magetsi.

Ma fuse a DC amagwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikizapo makina amagetsi a magalimoto ndi ndege, mapanelo a dzuwa, makina a batri, ndi makina ena amagetsi a DC. Ndi chitetezo chofunikira chomwe chimathandiza kuteteza ku moto wamagetsi ndi zoopsa zina.
