Kugwira Ntchito kwa Dropout Fuse Cutout

Kukonzekera chitetezo:

Akatulutsa fuse ya mtundu wa dontho, wogwiritsa ntchitoyo ayenera kugwiritsa ntchito ndodo yotetezera kutentha yokhala ndi mphamvu yoyenera yamagetsi ndikupambana mayesowo, kuvala nsapato zotetezera kutentha, magolovesi otetezera kutentha, chipewa ndi magalasi oteteza kutentha, kapena kuyimirira pa nsanja youma yamatabwa, ndikuyang'aniridwa kuti ateteze chitetezo cha munthu.

Zolemba:

Wogwiritsa ntchito akayamba kapena kutseka fuse yokoka kapena kutseka, sipadzakhala kukhudza kulikonse. Kukhudzako kudzawononga fuse, monga kukoka ndi kuswa chotenthetsera, kupotoza mulomo wa bakha, kukoka ndi kuswa mphete yogwirira ntchito, ndi zina zotero. Ogwira ntchito sayenera kugwiritsa ntchito mphamvu zambiri panthawi yogwiritsira ntchito fuse yamtundu wa dontho, kuti apewe kuwonongeka kwa fuse, ndipo kugawanika ndi kutseka kuyenera kukhala pamalo ake.

Mphamvu ya fuse ndi yochedwa (kuyamba) - mofulumira (pamene cholumikizira chosuntha chili pafupi ndi cholumikizira chosasunthika) - pang'onopang'ono (pamene cholumikizira chosuntha chili pafupi ndi mapeto a kutseka). Njira yokoka fuse ndi yochedwa (kuyamba) - mofulumira (pamene cholumikizira chosuntha chili pafupi ndi cholumikizira chosasunthika) - pang'onopang'ono (pamene cholumikizira chosuntha chili pafupi ndi mapeto a kukoka). Mwachangu ndi kupewa magetsi afupikitsa ndi kuyatsa ma contacts omwe amayambitsidwa ndi arc, pang'onopang'ono ndi kupewa kugwira ntchito kwa mphamvu yokhudza, zomwe zimapangitsa kuti fuse iwonongeke ndi makina.

Tumizani oda

Ndondomeko ya ntchito yoyimitsa magetsi a transformer yogawa ndi iyi: Nthawi zonse, chosinthira chamagetsi otsika chomwe chili kumbali ya katundu chiyenera kukokedwa kaye, kenako fuse yotsitsa magetsi amphamvu yomwe ili kumbali yamagetsi iyenera kukokedwa.

Pankhani ya magetsi ambiri, malinga ndi ndondomeko yomwe yatchulidwa pamwambapa, imatha kuletsa transformer kubwerera, ngati yalephera, chitetezo chingakane kusuntha, kuwonjezera nthawi yochotsa cholakwika, kupangitsa ngozi kukula. Ntchito yotumizira pang'onopang'ono kuchokera kumbali ya magetsi imatha kuchepetsa mphamvu yoyambira (katundu), kuchepetsa kusinthasintha kwa magetsi, ndikuwonetsetsa kuti zida zikugwira ntchito bwino. Ngati yalephera, imatha kupunthwa kapena kuyimitsa ntchito nthawi yomweyo, ndikosavuta kuyang'ana, kuweruza ndi kuthana nayo malinga ndi kuchuluka kwa magetsi. Ngati yalephera, siyani kaye mbali ya katundu. Pankhani ya kulephera kwa magetsi pang'onopang'ono kuchokera pa voliyumu yotsika kupita ku voliyumu yayikulu, switch imatha kupewa kudula mphamvu yayikulu ndikuchepetsa kuchuluka ndi kuchuluka kwa ntchito pa voliyumu.

Mu ntchito, yesetsani kupewa kukoka ndi kugwetsa ma fuse okhala ndi katundu. Ngati zapezeka kuti ma fuse okhala ndi katundu sanayende bwino panthawi yogwira ntchito, ngakhale ma fuse atasokonekera kapena ngati arc itachitika, siziloledwa kutsegula ma fuse kachiwiri. Ngati fuse yolakwika yokhala ndi katundu itachitika, pamene kukhudza kosuntha kungochoka pa kukhudzana kokhazikika, arc idzachitika. Panthawiyi, iyenera kutsekedwa nthawi yomweyo kuti ichotse arc ndikupewa kukula kwa ngoziyo. Komabe, ngati ma fuse onse atsegulidwa, siziloledwa kutsekanso ma fuse omwe adakokedwa molakwika. Kwa ma transformer ogawa omwe ali ndi mphamvu ya 200 kva kapena kuchepera, ma fuse omwe ali kumbali yamagetsi okwera amaloledwa kulekanitsa ndikuphatikiza mphamvu yamagetsi.

Ndondomeko yogwirira ntchito

Fuse yotsitsa ma voltage ambiri imagwira ntchito magawo atatu.

Kulephera kwa mphamvu, choyamba ayenera kukoka gawo lapakati, kenako kukoka mbali zonse ziwiri za gawolo.

Chifukwa chachikulu chokokera gawo lapakati choyamba ndi kuganizira kuti mphamvu yamagetsi ikadulidwa gawo lapakati ndi yocheperapo kuposa gawo la m'mbali (gawo la katundu wa dera limanyamulidwa ndi magawo awiriwa), kotero arc ndi yaying'ono, ndipo palibe choopsa mbali ziwiri za gawoli. Pamene fuse ya mtundu wa drop ya gawo lachiwiri (gawo la mbali) ikugwiritsidwa ntchito, mphamvu yamagetsi imakhala yayikulu, pomwe gawo lapakati latsegulidwa, ndipo ma fuse ena awiri a mtundu wa drop ali kutali kwambiri, zomwe zingalepheretse short circuit pakati pa magawo omwe amachitika chifukwa cha arc yayitali. Pakakhala mphepo yamphamvu, choyamba tiyenera kukoka gawo lapakati, kenako kukoka gawo la lee, ndipo potsiriza kukoka gawo la windward motsatira dongosolo la kulephera kwa mphamvu.

Mukatumiza magetsi, mbali ziwiri za gawo loyamba, pambuyo pa gawo lapakati.

Mphamvu ikaperekedwa, gawo loyamba la mphepo, kenako kubwerera ku gawo la phoenix, ndipo pamapeto pake gawo lapakati, kuti aletse kufupika kwa dera komwe kumachitika chifukwa cha mphepo.

Chidziwitso chokhazikitsa

Malangizo Oyenera Kutsatira Pakuyika Fuse Yotsitsa Mphamvu Yamagetsi Yapamwamba

1, kuyika kuyenera kukhala kusungunuka kwa mphamvu (kusungunuka ndi mphamvu ya pafupifupi 24.5N), apo ayi ndikosavuta kuyambitsa kutentha kwa tsitsi.

2, fuse yomwe yaikidwa pa mkono wopingasa (chimango) iyenera kukhala yolimba komanso yodalirika, singathe kukhala ndi chinthu chilichonse chogwedeza kapena kugwedeza.

3. Chitoliro chosungunula chiyenera kukhala ndi ngodya yozungulira ya 25°±2°, kotero kuti chitoliro chosungunula chikhoza kugwa mofulumira ndi kulemera kwake pamene kusungunuka kwasungunuka.

4. Fuse iyenera kuyikidwa pa mkono wopingasa (chimango) ndi mtunda woyima wosachepera 4m kuchokera pansi. Ngati yayikidwa pamwamba pa chosinthira chogawa, iyenera kusunga mtunda wopingasa woposa 0.5m kuchokera kumalire akunja a chosinthira chogawa, ngati ngozi zina zingachitike chifukwa cha kugwa kwa mapaipi osungunuka.

5. Kutalika kwa chitoliro chosungunula kuyenera kusinthidwa moyenera. Ndikofunikira kuti lilime la pakamwa pa bakha lizitha kukulunga kupitirira magawo awiri mwa atatu a kutalika kwa kukhudzana pambuyo potseka, kuti tipewe kuchitapo kanthu kolakwika kodzigwetsa lokha panthawi yogwira ntchito.

6. Kusungunuka komwe kumagwiritsidwa ntchito kuyenera kukhala chinthu chokhazikika cha wopanga wamba, ndipo kumakhala ndi mphamvu inayake yamakina. Kawirikawiri, kusungunukako kumatha kupirira mphamvu yokoka yoposa 147N osachepera.

7. Fuse ya mtundu wa drop ya 10kV imayikidwa panja, ndipo mtunda pakati pa magawo ndi woposa 70cm.
