Fuse yamtundu wa dontho ndiyo njira yodzitchinjiriza yomwe imagwiritsidwa ntchito kwambiri pamizere yanthambi ya mizere yogawa ya 10kV ndi zosinthira zogawa.Iwo ali makhalidwe a chuma, ntchito yabwino, kusinthasintha amphamvu kwa chilengedwe panja ndi zina zotero.Amagwiritsidwa ntchito kwambiri mbali yoyamba ya mizere yogawa ya 10kV ndi zosinthira zogawa pofuna chitetezo ndi kusintha kwa zida ndi ntchito yodula.
 
Imayikidwa pamzere wa nthambi wa 10kV wogawa mzere, womwe ungachepetse kuchuluka kwa kulephera kwa mphamvu.Chifukwa cha mawonekedwe ake odziwikiratu amtundu wa fuse yotsika kwambiri, imakhala ndi ntchito yodzipatula, yomwe imapanga malo ogwirira ntchito otetezeka a mzere wokonza ndi zida, ndikuwonjezera chidziwitso cha chitetezo cha ogwira ntchito yokonza. kugawa thiransifoma, angagwiritsidwe ntchito ngati chitetezo chachikulu cha thiransifoma kugawa, kotero wakhala wotchuka mu mzere kugawa 10kV ndi kugawa thiransifoma.
 

Kuyika kwa fuse yamtundu wa drop-type:

(1) pakukhazikitsa, kusungunula kuyenera kumangirizidwa (kotero kuti kusungunula kuli pafupi ndi 24.5N kupanikizika), mwinamwake ndizosavuta kuyambitsa kutentha kwa tsitsi.

(2) fuseyoyo iyenera kukhazikitsidwa mwamphamvu komanso modalirika pamtanda (frame) popanda kugwedezeka kapena kugwedezeka.

(3) chitoliro chosungunula chiyenera kukhala ndi Angle yotsika ya 25 ° ± 2 °, kuti chitoliro chosungunuka chigwe mofulumira ndi kulemera kwake pamene chisungunulacho chikusakanikirana.

(4) fuyusiyo idzakhazikitsidwa pa mkono wopingasa (chimango) ndi mtunda wokhazikika wosachepera 4m kuchokera pansi.Ngati atayikidwa pamwamba pa thiransifoma yogawa, mtunda wopingasa pakati pa fusesi ndi malire akunja a contour a thiransifoma udzasungidwa pamtunda wopitilira 0.5m, ngati pachitika ngozi zina chifukwa cha kugwa kwa fuse.

(5) kutalika kwa fusesi kudzasinthidwa kukhala pamlingo wapakatikati.Zimafunika kuti lilime la mlomo wa bakha ligwire kupitirira magawo awiri pa atatu a kutalika kwa kukhudzana pambuyo potseka, kuti apewe zolakwika zodzigwetsa pakugwira ntchito.

(6) kusungunula ntchito ayenera kukhala muyezo mankhwala a opanga nthawi zonse, ndi mphamvu inayake makina, zofunika ambiri a Sungunulani akhoza kupirira osachepera 147N kuposa mavuto.

(7) fuse ya mtundu wa dontho ya 10kV idzayikidwa panja ndipo mtunda wa interphase ukhale woposa 70cm.
 
Kugwiritsa ntchito fuse ya dontho:

Muzochitika zachilendo, sikuloledwa kugwiritsa ntchito fusesi yotsika ndi katundu, imangolola kuti igwiritse ntchito zipangizo zopanda katundu (mzere). Komabe, osinthira ogawa omwe ali ndi mphamvu zosakwana 200kVA ndi mizere ya nthambi ya mizere yogawa 10kV mu maukonde aulimi. amaloledwa kugwira ntchito pansi pa katundu molingana ndi izi:

(1) ntchitoyi idzachitidwa ndi anthu awiri (munthu m'modzi woyang'anira ndi munthu mmodzi kuti azigwira ntchito), pokhapokha atavala magolovesi otetezera oyenerera, nsapato zotetezera ndi magalasi, ndikugwira ntchito ndi ndodo zotetezera zoyenerera ndi milingo yofanana yamagetsi.Ntchitoyi ndiyoletsedwa panyengo yamphezi kapena mvula yambiri.

(2) pokoka opareshoni ya brake, nthawi zambiri imanenedwa kukoka gawo lapakati poyamba, ndiye gawo la mbali ya leeward, ndipo pamapeto pake gawo lambali la mphepo. kukoka gawo lapakati lomwe limapangidwa ndi arc spark yochepa, silingapangitse kuti pakhale dera lalifupi pakati pa. ngakhale pali overvoltage, zomwe zimapangitsa kuti dera laling'ono pakati pa zotheka likhale laling'ono kwambiri.Potsirizira pake, pamene gawo la upwind limakoka, kokha capacitive panopa pansi, chifukwa chake chakhala chochepa kwambiri.

(3) pamene chosinthira chatsekedwa, ndondomeko yoyendetsera ntchito imasinthidwa pamene chosinthira chikukoka.Choyamba, gawo lakutsogolo limatsekedwa, kenako gawo la leeward limatsekedwa, ndipo pamapeto pake gawo lapakati limatsekedwa.

(4) ntchito ya chubu chosungunuka ndi ntchito kawirikawiri.Ngati simusamala, zingayambitse kukhudzana ndi kutentha ndikuyambitsa kukhudzana koyipa.Kukhudzana kudzakhala kutenthedwa ndipo kasupe adzakhala annealed.Choncho, kukoka, kutseka chubu chosungunuka kukakamiza zolimbitsa, kutseka bwino, kuyang'ana mosamala lilime akhoza mwamphamvu kumanga lilime magawo awiri pa atatu a kutalika kwa pamwamba, mukhoza kukoka. mbedza ya brake pakamwa pa bakha kukanikizira pansi kangapo, ndiyeno mofatsa yesani kukoka, fufuzani ngati ili bwino. osakwanira, ndikosavuta kuyambitsa kuyaka kapena kusungunuka kwa chubu
