Drop out fuse ndi chipangizo chakunja choteteza kwambiri chamagetsi.Ndiwo ma switch omwe amagwiritsidwa ntchito kwambiri poteteza dera lalifupi pamizere yanthambi ya mizere yogawa ndi zosinthira zogawa.Amagwiritsidwa ntchito makamaka kuteteza ma transfoma kapena mizere ku zotsatira zomwe zimachitika chifukwa chafupikitsa, kudzaza ndi kusintha kwapano.Iwo ali makhalidwe a chuma, ntchito yabwino ndi amphamvu kusinthasintha kwa chilengedwe panja.Pansi pa vuto lapano, fuseyo imawombera ndikupanga arc.Chubu chozimitsira arc chimatenthedwa ndikuphulika, zomwe zimapangitsa kuti magetsi azikwera kwambiri.Fuseyi tsopano ili pamalo otseguka ndipo wogwiritsa ntchito ayenera kuzimitsa zamakono.Tsekani ndi insulating otentha tepi.Kulumikizana kwakukulu ndi othandizira alumikizidwa.Imayikidwa pamzere wa nthambi wa 10kV wogawa mzere, womwe ungachepetse kuchuluka kwa magetsi.Chifukwa ili ndi malo odulirako oonekeratu, imakhala ndi ntchito yochotsa cholumikizira, kupanga malo ogwirira ntchito otetezeka amizere ndi zida zomwe zili mugawo lokonzekera, ndikuwonjezera chidziwitso chachitetezo cha ogwira ntchito yosamalira.

Kusaka zolakwika

(1) Fuse yomwe ili kumbali yoyambirira ya thiransifoma imagwiritsidwa ntchito ngati chitetezo chosungira thiransifoma palokha komanso cholakwika chachiwiri chamzere wotuluka.Imafanana ndi nthawi yochitirapo zachitetezo chamzere wotuluka, ndipo ikuyenera kukhala yocheperako kuposa nthawi yosweka ya chowotcha chamagetsi.Ndikofunikira kuti fuseyi ikhale yosakanikirana ndipo chowotcha chotuluka sichichita.Ngati mphamvu ya thiransifoma ili pansi pa 100kV.A, fuyusi yomwe ili kumbali yoyambirira ikhoza kusankhidwa ngati nthawi 2-3 pakali pano;Kwa thiransifoma yogawa ya 100kV.A ndi kupitilira apo, fusesi yomwe ili kumbali yoyambira imatha kusankhidwa ngati nthawi 1.5 ~ 2 yapano yovotera.

(2) Fusesi yayikulu ya nthambi imagwiritsidwa ntchito kwambiri poteteza mochulukira.Nthawi zambiri, mawonekedwe a fuseyi amasankhidwa molingana ndi kuchuluka kwazomwe zikuchitika pamzere wa nthambi.Nthawi yophatikizira ikuyenera kukhala yocheperako kuposa nthawi yokhazikitsira chipangizo chachitetezo cham'munsi chomwe chikutuluka.

(3) Akaunti yoyendetsera ntchito ndi kukonza ndi dongosolo la ma fuse osiya adzakhazikitsidwa.Ma fuse osiya omwe akhala akugwira ntchito kwa zaka zopitilira 5 azisinthidwa m'magulu.

(4) Kupititsa patsogolo luso laumisiri ndi kukonza njira zamagetsi.Mukayika kapena kusintha fusejiyo, mphamvuyo iyenera kukhala yoyenera kuti isatayike kapena yothina kwambiri.

(5) Paziwopsezo za kuponya kosagwirizana kumapeto onse a chubu cha fuse, wopanga azichita chithandizo cha "chamfering" kapena kukonza zina.

Kuyika ma fuse otuluka

(1) Pakuyika, kusungunula kuyenera kuimitsidwa (kotero kuti kusungunula kungathe kupirira mphamvu yamphamvu ya 24.5N), mwinamwake kukhudzana kungakhale kotentha.Fuse yomwe imayikidwa pamtanda (chimango) ikhale yolimba komanso yodalirika popanda kugwedeza kapena kugwedezeka.

(2) Chubu chosungunukacho chimakhala ndi ngodya yotsika ya 25 ° ± 2 °, kotero kuti chubu chosungunuka chikhoza kugwa mofulumira ndi kulemera kwake pamene chikuphulika.

(3) Fusezi idzayikidwa pa mtanda mkono (chimango).Pazifukwa zachitetezo, mtunda woyima kuchokera pansi suyenera kuchepera 4m.Ngati itayikidwa pamwamba pa chosinthira chogawa, mtunda wopingasa wopitilira 0.5m uyenera kusungidwa kuchokera kumalire akunja a contour ya chosinthira chogawa.Kugwa kwa chitoliro chosungunuka kunayambitsa ngozi zina.

(4) Kutalika kwa fusesi kumayenera kusinthidwa moyenera.Kuganizira zachitetezo kumafuna kuti bakhayo azitha kusunga kupitilira magawo awiri mwa atatu a kutalika kwa kukhudzana kwake atatsekedwa kuti asadzigwere pakugwira ntchito.Fuse chubu sayenera kukhudza duckbill kuteteza chubu kusungunuka kugwa mu nthawi kusungunuka kuphulika.

(5) Kusungunula komwe kumagwiritsidwa ntchito kuyenera kukhala kokhazikika kwa wopanga nthawi zonse komanso kukhala ndi mphamvu zamakina.Kuganizira zachitetezo nthawi zambiri kumafuna kuti kusungunuka kumatha kupirira mphamvu yopitilira 147N.

(6) 10kV dropout fuse imayikidwa panja kuti itetezeke ndipo mtunda uyenera kukhala wamkulu kuposa 70cm.

Zindikirani: Nthawi zambiri, sikuloledwa kugwiritsa ntchito fuseyi pa katundu, koma amaloledwa kugwiritsa ntchito zipangizo zopanda katundu (mzere).Komabe, muzochitika zinazake, amaloledwa kunyamula ngati pakufunika
