Fuse yochepetsa mphamvu yamagetsi yamagetsi imagwira ntchito ku AC 50Hz yamkati, ma voliyumu ovotera a 3.6KV, 7.2KV, 12KV, 24KV, 40.5KV, mafunde ovotera a 0.5 ndi 2, 3, 5, 7.5, 10A, ndipo amagwiritsidwa ntchito poteteza makina kuchulukirachulukira komanso kulakwitsa kwapang'onopang'ono kwamagetsi akunja a 35KV ndi mizere yamagetsi.Itha kugwiritsidwa ntchito limodzi ndi zida zina zosinthira, monga masiwichi a katundu ndi zolumikizira zenizeni, ngati chinthu chodzitchinjiriza chafupikitsa ndikuchulukira kwa osinthira mphamvu ndi zida zina zosunga zobwezeretsera, komanso ndizofunikira zothandizira mafelemu apamwamba kwambiri amagetsi, mphete. mafelemu a netiweki, ndi malo apamwamba/otsika-voltage opangiratu.
Fuse yochepetsa mphamvu yamagetsi yamagetsi imakhala ndi malire apano komanso kuthamanga.Mtengo wapamwamba wa fault current nthawi zambiri umawonekera theka wave.Pamene thupi la mlatho lichotsedwa, mphamvu zonse zazifupi zidzasamutsidwa ku fuse yamagetsi yamagetsi yamagetsi.Mphamvu yamkati ya fuseyi idzasungunuka, kusweka, kupanga arc pakati pa mipata ndikuzimitsa arc m'tsogolomu komanso ikakwera, kuchepetsa ndi kudula mwamphamvu njira yachidule (t ＜ 2ms), kotero kuti panopa sangathe. kufika pachimake pamtengo woyembekezeka waposachedwa.Mphamvu yofupikitsa ikakwera kupita ku Ip, fuseyo imaphatikizana ndikudula mphamvu.Ip yamakono yodulidwa ndi pafupifupi 15% yokha ya mtengo wapamwamba wa zomwe zikuyembekezeredwa panopa, kuchepetsa kwambiri zotsatira za vuto lamakono pa mphamvu ya electrodynamic ndi kutentha kwa magetsi opangira magetsi ndi zida zosinthira.Mphamvu yamagetsi ya arc yomwe imapangidwa ndi fuse yamagetsi yamagetsi yamagetsi yamagetsi imatha kuchepetsedwa ndi kukana kosagwirizana, komwe kumatha kugwirizana ndi kukana kwa mlatho kuti athetse vuto la kuchepa kwa mphamvu yamagetsi yamagetsi yamagetsi yamagetsi komanso kuwongolera magwiridwe antchito amtundu wonsewo. chipangizo.
Fuseyi imapangidwa ndi chubu chosungunula, chotchinga cha porcelain (silicone rubber insulation sheath), flange yomangirira, transverse post insulator ndi terminal.Konzani zisoti zotsekera ndi kusungunula mipope pa malekezero onse mu porcelain bushing ndi kukanikiza, ndiyeno konzani zadothi bushing pa ndodo post insulator ndi flange olimba.
Chitoliro chosungunula chimatenga chisamaliro chokhala ndi silicon oxide yayikulu ngati njira yozimitsira arc, ndipo waya wachitsulo wokhala ndi mainchesi ochepa amagwiritsidwa ntchito ngati fuyusi.Pamene kuchulukirachulukira panopa kapena yochepa dera panopa akudutsa mu chubu Sungunulani, fusesi adzasungunuka yomweyo.Arc imapezeka m'mipata ingapo yopapatiza.Nthunzi yachitsulo mu arc imalowa mu mchenga wa quartz, imasiyanitsidwa kwambiri, ndipo imazimitsa mwamsanga arc.Chifukwa chake, fuyusiyo imakhala ndi magwiridwe antchito abwino komanso kusweka kwakukulu.

1. Mkulu kuswa mphamvu.Nthawi zambiri, ma fuse ochepetsa mphamvu yamagetsi am'nyumba ndi 50kA, ndipo mphamvu yanthawi yochepa ya zinthu zomwe zimatumizidwa kunja zimafika 63kA.
2. Kuthekera kochepetsa mphamvu, nthawi zambiri m'nyumba zochepetsa mphamvu yamagetsi yamagetsi, monga ma fuse a 100A, nsonga yaposachedwa kwambiri imakhala pafupifupi 18kA pomwe mtengo wake wanthawi yayitali ndi 50kA, pomwe zina. Fuse ya 100A yotumizidwa kunja, mu Pamene mtengo woyembekezeka wafupipafupi ndi 63kA, nsonga yaposachedwa ndi 18kA yokha.
3. Pali kusweka pang'ono.Pamafusi oletsa kutetezedwa kwa thiransifoma, kusweka kocheperako nthawi zambiri kumakhala 3 mpaka 5 kuposa momwe fuyusiyo idavotera.Posankha, ziyenera kutsimikiziridwa kuti kusakaniza kwake kocheperako sikuli kokulirapo kuposa kagawo kakang'ono kakang'ono ka dera lotetezedwa.
4. Kutayika kwa mphamvu kumakhala kochepa, komwe kumatsimikizira kuti mankhwalawa ali ndi kutentha kochepa.Izi zimakhala zopindulitsa kwambiri fuseyo ikagwiritsidwa ntchito mu chipangizo chotchinga chotsekedwa bwino.Low arc voltage: Panthawi yosweka, mphamvu ya arc imakhala yotsika, ndipo ikagwiritsidwa ntchito m'dongosolo lokhala ndi voteji yotsika kuposa mphamvu yamagetsi, mphamvu ya arc idzachepetsedwa, kotero kuti fuse ya 12KV ingagwiritsidwe ntchito 12KV kapena 7.2KV dongosolo popanda kuwononga dongosolo kutchinjiriza ngozi.
5. Kulakwitsa kwa khalidwe lachidziwitso ndi laling'ono, ndipo kulakwitsa kwa nthawi yamakono kumakhala kochepa kuposa ± 10%, zomwe zimatsimikizira kudalirika kwa mankhwala.Komanso, onse amatsatira muyezo wa International Electrotechnical Commission (IEC).Mtundu wa busbar ukhoza kumangirizidwa mwachindunji ku busbar ndi zomangira, zomwe zili ndi ubwino wa voliyumu yaying'ono yoyika ndi kukhudzana kodalirika;pamene mtundu wa pulagi ndi wosavuta kusintha ndipo ukhoza kuyendetsedwa ndi magetsi.
