Kufotokozera Kwachidule:

Chodulira fuse chodulira ndi chodulira fuse chosinthira katundu ndi chipangizo choteteza chamagetsi chakunja. Cholumikizidwa ndi chodyetsa cholowera cha kugawa, transformer kapena mizere yogawa. Chimateteza kwambiri transformer kapena mizere kufupi kwa circuit ndi overload ndi ON/OFF loading current. Chodulira fuse chodulira chimapangidwa ndi zothandizira zoteteza ndi chubu cha fuse. Zolumikizira zosasunthika zimakhazikika mbali ziwiri za chithandizo cha insulator, zolumikizira zosuntha zimayikidwa kumapeto kwa chubu cha fuse. Chubu cha fuse chimapangidwa ndi chubu chozimitsira chamkati cha arc. Chubu cha phenolic compound paper kapena epoxyglasstube. Chodulira fuse chosinthira katundu chimapereka zolumikizira zothandizira zokhazikika komanso chitetezo cha arc choyatsira magetsi otsegula. Pakagwira ntchito bwino, chubu cha fuse chimalimbikitsidwa kuti chikhale pafupi. Ngati dongosolo lalephera, magetsi olakwika amalola fuse kusungunuka nthawi yomweyo ndipo arc yamagetsi idzabweretsedwa, zomwe zimapangitsa chubu chozimitsira arc kutenthedwa ndikuthetsa mpweya wambiri. Izi zipanga kuthamanga kwambiri mu chubu, ndikuphulika pamodzi ndi chubu, kenako arc idzakulitsidwa ndikuzimitsidwa. Pambuyo poti fuse link yasungunuka, ma contact osuntha alibe mphamvu yolimba, chipangizo chotseka chimamasula fuse, chubu cha fuse chimatuluka, chodulacho chimakhala chotseguka. Chikafunika kuzimitsidwa panthawi yodula, gwiritsani ntchito mpira woteteza kukoka cholumikizira chosuntha, tsopano kulumikizana kwakukulu ndi ma contact othandizira akadali kulumikizana. Pamene akukoka, ma contact othandizira amalekanitsidwa, kenako arc yamagetsi imachitika pakati pa ma contact othandizira, arc imatambasulidwa mu arc shield, nthawi yomweyo arc shield imaphulika mpweya, pamene mphamvu yamagetsi imadzaza, imalola kuti izimitsidwe.
