Maulendo onse ogwiritsira ntchito magetsi, kuphatikizapo omwe ali panyumba panu, ayenera kutetezedwa ndi chipangizo chotetezera, kapena OCPD. Pakali pano ndi kuchuluka kwa amperage kudutsa kudutsa mu waya kapena dera, ndipo waya iliyonse kapena dera liri ndi chiwerengero chapamwamba chomwe chilipo tsopano . Pamene makonowa apitirira, OCPD imachotsa mphamvu yoyendetsa dera, kuteteza moto ndi zoopsa zina. M'mabanja ambiri lerolino, OCPD imagwiritsidwa ntchito pa maulendo onse ndi woyenda dera .
M'mabanja akale omwe ali ndi magetsi akuluakulu, OCPD mwina ndi fuseti. Kuunikira kwapadera ndi maulendo odzaza ndizitsulo. Maulendo apamwamba, monga omwe amagwiritsa ntchito magetsi ndi zowuma, amatetezedwa ndi cartridge fuses.
Momwe Fereji Zapangira Ntchito
Ma fuses onse , kuphatikizapo mafakitale a cartridge, ndi "kugwirizana kofooka" mu dera lamagetsi. Mkati mwa fuseji ndi mzere wolimba womwe umagwirizanitsidwa ndi zonse zitsulo za thupi la fuse. Ngati pali zochepa kapena zolakwika paliponse pa dera, kapena dera likunyamulidwa, chidutswa chachitsulo, kapena chiyanjano, chimatentha ndi kusungunuka mwamsanga, kutsegula dera ndi kutseka mphamvu. Ndili ngati mawotchi omwe amachoka kamodzi kokha, ndiye kuti ayenera kuwongolera. Pogwiritsa ntchito fereji ya cartridge, fuseti yatsopanoyo iyenera kukhala yofanana ndi yakaleyo ndipo ikhale yofanana ndi ya ma voltage. Izi ndizofunikira kuti chitetezo, ngati fuse yomwe ili yolakwika ingawononge moto wowopsya.
Foni ya fakitale ya Cartridge
Ma fuseti a cartridge ali ndi mawonekedwe osakanikirana ndipo ali ndi malo olankhulana pamapeto pake. Amayikidwa pa maulendo opitirira 30 amps ndipo amakhala 240 volts. Pali mitundu iwiri yofunikira ya friji ya cartridge. Mitundu ya fruu imayimilira mpaka kufika 60 amps. Ali ndi chipewa chachitsulo pamapeto onse ndipo amawoneka ngati ma fuses aakulu omwe mumapeza mkati mwa pulasitiki ya magetsi.
Mpope wa mpeni cartridus ndi mchimwene wamkulu wa mtundu wa ferrule. Chimodzimodzinso chili ndi tsamba lachitsulo pamtunda uliwonse. Mafusi a mpeni amagwiritsidwa ntchito poteteza maulendo opitirira 60 amps mpaka 600 amps.
Kumene Mungapeze Mafiripu a Cartridge
Makompyuta ambiri akale omwe ali ndi mabokosi a fuse (mosiyana ndi mabokosi amasiku ano ) ali ndi mabotolo awiri kapena kuposa, omwe ali ndi mafasho awiri a cartridge. Chimodzi mwazitsulo zopangira fuse ndi fuseti yaikulu. Iyi ndi OCPD ya bokosi lonse la fuseti ndipo potero maulendo onse a nthambi ali m'nyumba. Zida zina zimagwiritsa ntchito magetsi akuluakulu, kuphatikizapo zowuma, mitsinje, ma air conditioner, heaters, kapena heaters. Kuti mupeze mafelemu mkati mwa chipika, kukoketsani mosamala pa bwalo lamkuwa kapena chogwiritsira ntchito pa fuseti. Gwiritsani ntchito dzanja limodzi kuti mutulutse chipika; Izi zimathandiza kuchepetsa mwayi wa electrocution ngati chinachake chikulakwika. Chotsani chipika chonsecho kuchokera mu bokosi. Kuti muchotse fuseti kuchokera kumalo ake, gwiritsani ntchito chipangizo chopangira fuse, chida chopangidwa ndi pulasitiki kapena zipangizo zina zopanda chitetezo kuti muteteze. Sakanizani mafayilo m'malo moyambirira.
