Kucheka fuse inodonhedzwa uye kuchekwa kwefuse inochinjika mutoro zvinhu zvinodzivirira magetsi ekunze. Zvinofanira kubatanidzwa ne feeder inouya yekuparadzira, transformer kana mitsetse yekuparadzira. Inonyanya kudzivirira transformer kana mitsetse kubva ku short circuit uye overload uye ON/OFF loading current. Kucheka fuse inodonhedzwa ine insulator supports uye fuse tube. Static contacts dzakasungirirwa pamativi maviri e insulator support, mafambiro e contacts akaiswa pamagumo ekudhonza e fuse tube. Fuse tube yakagadzirwa ne arc extinguishing tube yemukati. Outlineer phenolic compound paper tube kana epoxyglasstube. Kucheka fuse inochinjika mutoro inopa elastic assistant contacts uye arc shield yekudzima on-off loading current. Pakushanda kwakajairika, fuse link yakasimbisirwa, fuse tube inogadziriswa kuti iite close position. Kana system ikaitika fault, fault current inorega fuse ichinyunguduka nekukasika uye electric arc inounzwa, iyo inoita kuti arc extinguishing tube ipiswe uye gasi rakawanda. Izvi zvinoburitsa high pressure mu tub, uye inoputika pamwe chete ne tube, uye arc inozowedzerwa uye inodzimwa. Mushure mekunge fuse link yanyunguduka, macontacts anofambiswa haana simba rakasimba, mudziyo wekukiya unosunungura fuse, chubhu yefuse inodonha, cutout yava munzvimbo yakavhurika. Kana ichida kudzima panguva yekucheka, shandisa bhora rekushandisa rinodzivirira kuputira contact, ikozvino main contacts ne assistant static contacts dzichiri kubata. Paunenge uchidhonza, macontacts anofambiswa anoparadzaniswa, uye ipapo arc yemagetsi inoitika pakati pemacontacts anofambiswa, arc inotambanudzwa mu arc shield, panguva imwe chete arc shield inoputika gasi, kana current overload, rega idzime.
