Drop-out cutout fuse uye load switching cutout fuse ndeyekunze inoshandiswa yakakwira voltage inodzivirira mudziyo. Kuti ibatanidzwe neanouya feeder yekugovera transformer kana distribu-tion mitsara iyo inonyanya kudzivirira transformer kana mitsara kubva kupfupi kutenderera uye kuremerwa, uye pa/kubvisa kurodha ikozvino. arc-kudzimisa chubhu, ekunze phenoilc compound bepa chubhu kana epoxy girazi chubhu.Kutakura switching cutout fuse inopa yakasimbiswa elastic auxil-iary contacts uye arc-kudzimisa enclosure yekudzima / kudzima kurodha ikozvino.

Paunowanzo shanda kuburikidza nefuselink yakasimbiswa chubhu yefuse inogadziriswa kuti iite padyo nzvimbo.Kana system ikaitika kukanganisa, fuse inokonzeresa kuti fuse inyunguduke nekukasira yotora nzvimbo yemagetsi arc, inoita kuti arc-kudzimisa chubhu ichidziiswa uye kuputika gasi rakawanda. Izvi zvinoburitsa kudzvinyirirwa kwepamusoro uye kuvhuvhuta arc pamwe nechubhu.Mushure me fuselink melt inofamba inobata haina simba rakasimbiswa zvakare,mechanism yakavharwa uye fuse chubhu inodonha kunze. Cutout ikozvino iri panzvimbo yakashama. Kana ichida kudzima panguva yekucheka kurodha, opareta achashandisa insulating inoshanda bar kudhonza iyo inofamba, painotangira-ning main yekubata uye yekubatsira static yekubata inobatwa ichiri. Pakukweva iyo yekubatsira yekubatanidza inopatsanurwa pakati pevabatsiri vanobatana panoitika arc yemagetsi uye arc icharebeswa muarc-kudzimisa yakavharwa gap uye ukuwo arc-kudzimisa gasi rinoputika kuti ribvise arc panguva inodarika zero.
