Mwachidule
Fyuzi yotsika ndi yosinthira katundu ndi zida zoteteza panja zamphamvu kwambiri.Amalumikizidwa ndi mzere wolowera kapena mzere wogawa wa transformer yogawa.Izi zimagwiritsidwa ntchito makamaka kuteteza ma transfoma kapena mizere kuchokera kufupipafupi, kudzaza ndi kusintha kwamakono.Fusesiyi imakhala ndi bulaketi ya insulator ndi chubu cha fuse.Ma static contacts amakhazikika mbali zonse za bulaketi ya insulator, ndipo zolumikizira zosunthika zimayikidwa malekezero onse a fuse chubu.Mkati mwa chubu la fusesi muli payipi yamoto.Kunja kumapangidwa ndi phenolic composite paper chubu kapena epoxy glass.Fusesi yosinthira katundu imapereka kulumikizana kothandizira komanso kutseka kwachipinda cha arc kuti mutsegule / kutseka katundu wapano.
Panthawi yogwira ntchito bwino, fuseyi imakokera pamalo otsekedwa.Pazovuta zomwe zikuchitika, ulalo wa fusewu umasungunuka ndikupanga arc.Izi ndizochitika za chipinda chozimitsira arc.Izi zimapanga kuthamanga kwakukulu mu chubu ndikupangitsa chubu kupatukana ndi zolumikizana.Fuseyo ikasungunuka, mphamvu ya olumikizana nawo idzamasuka.Wowononga dera tsopano ali pamalo otseguka ndipo woyendetsa ayenera kuzimitsa panopa.Zomwe zimasuntha zimatha kukokedwa pogwiritsa ntchito ma insulated levers.Kulumikizana kwakukulu ndi kulumikizana kothandizira kumalumikizidwa.

(1) Kuti fuseyo igwire ntchito modalirika komanso motetezeka, kuwonjezera pakusankha mosamalitsa zinthu zoyenerera ndi zowonjezera (kuphatikiza magawo a fusible) opangidwa ndi opanga ovomerezeka molingana ndi zomwe malamulowo amafunikira, zinthu zotsatirazi ziyenera kuyang'aniridwa mwapadera. mu ntchito ndi kasamalidwe kasamalidwe:
① Onani ngati mawonekedwe a fusesi amafanana ndi kusungunula ndi kunyamula mitengo yapano moyenera.Ngati kufananitsa sikuli koyenera, kuyenera kusinthidwa.
② Ntchito iliyonse ya fuseyi iyenera kukhala yosamala komanso yosamala, osati yosasamala, makamaka ntchito yotseka.Zolumikizana zosunthika komanso zosasunthika ziyenera kukhala zolumikizana bwino.
③ Kusungunuka kokhazikika kuyenera kugwiritsidwa ntchito mu chitoliro chosungunuka.Ndizoletsedwa kugwiritsa ntchito waya wamkuwa ndi waya wa aluminiyamu m'malo mwa kusungunuka, ndipo sikuloledwa kugwiritsa ntchito waya wamkuwa, waya wa aluminiyamu ndi waya wachitsulo kuti amangirire kukhudzana.
④ Pamafusi omwe angokhazikitsidwa kumene kapena osinthidwa, njira yovomerezera iyenera kuchitidwa mosamalitsa, ndipo zofunikira zamalamulo ziyenera kukwaniritsidwa.Kukhazikitsa ngodya ya fuse chubu kufika pafupifupi 25 °.
⑤ Chosungunuka chosungunuka chidzasinthidwa ndi china chatsopano chofanana.Sichiloledwa kulumikiza chosakaniza chosungunuka ndikuchiyika mu chubu chosungunuka kuti chigwiritsidwe ntchito.
⑥ Fuseyi iyenera kuyang'aniridwa nthawi zonse, kamodzi pamwezi usiku, kuti muwone ngati pali kutulutsa kotulutsa komanso kusakhudzana bwino.Ngati pali kutulutsa, padzakhala phokoso loyimba, lomwe liyenera kuchitidwa mwamsanga.
(2) Kuyang'anira kotsatiraku kudzachitika kuti pakhale fuse panthawi yoyendera kasupe ndi kukonza kuzima:
① Kaya kukhudzana pakati pa kukhudzana kokhazikika ndi kusuntha kumagwirizana, kolimba komanso kokhazikika, komanso ngati pali chizindikiro chowotcha.
② Kaya mbali zozungulira za fusesi zimakhala zosinthika, zadzimbiri, zosasunthika, ndi zina zotero, kaya zawonongeka, komanso ngati kasupe ali ndi dzimbiri.
③ Kaya chosungunulacho chawonongeka kapena ayi, komanso ngati pali kutentha kwapakati komanso kufooka pambuyo poyatsa mphamvu yayitali.
④ Kaya chubu chopondereza cha arc chopangira gasi mu chubu chosungunuka chatenthedwa, kuonongeka ndi kupunduka pambuyo padzuwa ndi mvula, komanso ngati kutalika kwake kumafupikitsidwa pambuyo pochita zinthu zingapo.
⑤ Tsukani chotchingira ndikuwona ngati chawonongeka, ming'alu kapena kutulutsa.Mukachotsa mayendedwe apamwamba ndi otsika, gwiritsani ntchito 2500V megger kuyesa kukana kwa insulation, komwe kuyenera kukhala kwakukulu kuposa 300M Ω.
⑥ Onani ngati zolumikizira zakumtunda ndi zapansi za fuseyi ndizotayirira, zatulutsidwa kapena zatenthedwa.
Zowonongeka zomwe zapezeka muzinthu zomwe zili pamwambazi ziyenera kukonzedwa bwino ndikusamalidwa.
Kusungunuka kwa chubu:
Fuseyi imapangidwa ndi flberglsaa, yomwe imakhala ndi chinyezi komanso kusachita dzimbiri.
Fuse maziko:
Zomwe zimapangidwira zimaphatikizidwa ndi zida zamakina ndi ma insulators.Dongosolo lachitsulo limayikidwa ndi zinthu zapadera zomatira ndi insulator, zomwe zimatha kupirira nthawi yayitali kuti muyatse mphamvu.
Fuse yotsimikizira chinyezi ilibe thovu, palibe mapindikidwe, palibe dera lotseguka, mphamvu yayikulu, anti-ultraviolet, moyo wautali, zida zapamwamba zamagetsi, mphamvu ya dielectric komanso kulimba kwamakina komanso kudzipereka.
Makina onsewo ndi osalowerera, osavuta kukhazikitsa, otetezeka komanso odalirika.
