Ma fuse otsitsa a RW12 ndi zida zakunja zodzitchinjiriza panja pamakina otumizira ndi kugawa magetsi.Iwo anaika pa mkulu-voltage mbali ya thiransifoma kugawa kapena pa nthambi mizere yogawa mizere, ndipo ntchito yochepa dera ndi overload chitetezo cha thiransifoma ndi mizere, komanso kugawanika ndi kuphatikiza katundu mafunde.Fusesi ya ceramic yotsika kwambiri yamagetsi imapangidwa ndi bulaketi ya ceramic insulating ndi chubu cha fuse.Kulumikizana kosasunthika kumayikidwa kumalekezero onse a bulaketi yotsekera, ndipo cholumikizira chosuntha chimayikidwa kumapeto kwa fuse chubu.Chubu cha fusechi chimapangidwa ndi chubu chamkati cha arc komanso chubu cha fuse.Wosanjikiza akunja amapangidwa ndi phenolic pepala chubu kapena epoxy galasi nsalu chubu.Fuse yamtundu wotsitsa katundu imakulitsa cholumikizira chothandizira cholumikizira ndi chivundikiro chozimitsa cha arc kuti chigawike ndikuphatikiza katundu wapano.

Kapangidwe kazinthu ndi kuchuluka kwa ntchito

Sungunulani chubu kapangidwe:
Fuse take yopangidwa ndi flberglsaa, yosanyowa komanso yosawonongeka.
Fuse maziko:
Zopangira zida zophatikizidwa ndi makina amakina ndi insulator.Ikani makina opangira zitsulo pogwiritsa ntchito zida zapadera zomangira ndi insulator palimodzi, mutha kutsegula mphamvu yamagetsi yokhala ndi mawonekedwe afupiafupi.
Fuse yosasunthika ilibe matuza, mapindikidwe, otseguka, mphamvu yayikulu, UV, moyo wautali, zida zapamwamba zamagetsi, mphamvu ya dielectric ndi kuuma kwamakina kwabwino kwambiri komanso luso lodzipatulira.
Bungwe lonse kusalowerera ndale, yabwino unsembe, otetezeka ndi odalirika.
1. Kutentha kozungulira sikokwera kuposa +40 C, osati kutsika kuposa -40 C
2. Kutalika sikudutsa 3000m
3.Kuthamanga kwa mphepo sikudutsa 35m / s
4. Kuchuluka kwa chivomezi sikudutsa madigiri 8

Kuyika kwa Fuse ndi Kugwiritsa Ntchito

1. Kuyika kwa fuse yotsitsa:
(1) Kusungunula kuyenera kumangirizidwa pakuyika (kotero kuti kusungunuka kukhale ndi mphamvu yowonongeka ya 24.5N), mwinamwake ndizosavuta kuchititsa kuti kukhudzana kutenthedwe.
(2) Fuse yomwe imayikidwa pamtanda (chimango) iyenera kukhala yolimba komanso yodalirika, ndipo pasakhale kugwedezeka kapena kugwedezeka.
(3) Chubu chosungunuka chiyenera kukhala ndi ngodya yotsika pansi ya 25 ° ± 2 °, kotero kuti chubu chosungunula chikhoza kugwa mofulumira ndi kulemera kwake pamene kusungunuka kuphulika.
(4) Fusezi iyenera kukhazikitsidwa pamtanda mkono (chimango) ndi mtunda ofukula osachepera 4m kuchokera pansi.Ngati itayikidwa pamwamba pa thiransifoma yogawa, iyenera kukhala ndi mtunda wopingasa wopitilira 0.5m kuchokera kumalire akunja kwa chosinthira chogawa.Kugwa kwa chubu chosungunuka kunayambitsa ngozi zina.
(5) Kutalika kwa chubu cha fuse chiyenera kusinthidwa moyenera.Zimafunika kuti lilime la duckbill lizitha kupitilira magawo awiri pa atatu a kutalika kwa kukhudzana pambuyo kutseka, kuti apewe misoperation kudzigwetsa pa ntchito, ndi fuse chubu sayenera kugunda duckbill., pofuna kuteteza chubu chosungunuka kuti chisagwe pakapita nthawi chisungunukocho chikawombedwa.
(6) Kusungunuka komwe kumagwiritsidwa ntchito kuyenera kukhala kokhazikika kwa wopanga nthawi zonse, ndipo kumakhala ndi mphamvu zamakina.Nthawi zambiri, kusungunuka kumafunika kupirira mphamvu yopitilira 147N.
(7) Fuse yotsitsa ya 10kV imayikidwa panja, ndipo mtunda pakati pa magawo uyenera kukhala wamkulu kuposa 70cm.
Chachiwiri, kugwira ntchito kwa fuse yotsitsa:
Muzochitika zodziwika bwino, sikuloledwa kugwiritsa ntchito fuseti yotsitsa ndi katundu, imaloledwa kugwiritsa ntchito zida zopanda katundu (mzere).Komabe, mizere ya nthambi ya mizere yogawa 10kV m'magulu amagetsi akumidzi ndi zosinthira zogawa zokhala ndi mphamvu zosakwana 200kVA zimaloledwa kugwira ntchito ndi katundu molingana ndi izi:
(1) Opaleshoniyo idzachitidwa ndi anthu awiri (m'modzi kuwunika ndi wina kugwira ntchito), koma ayenera kuvala magolovesi oteteza, nsapato zotchingira, ndi magalasi, ndikugwira ntchito ndi ndodo zotchingira zoyenererana ndi milingo yamagetsi yofananira.Ntchito ndiyoletsedwa pamvula yamphamvu.
(2) Panthawi yogwira ntchito pachipata, nthawi zambiri zimatchulidwa kuti gawo lapakati limakokedwa poyamba, ndiye kuti mbali ya leeward imakoka, ndiyeno mbali ya mphepo imakoka.Izi ndichifukwa choti chosinthira chogawa chimasinthidwa kuchokera ku gawo lachitatu kupita ku gawo la magawo awiri, ndipo kutsekemera kwa arc komwe kumapangidwa pamene gawo lapakati likusweka ndi laling'ono, lomwe silingadzetse dera lalifupi pakati pa magawo.Chachiwiri ndikuphwanya gawo la mbali ya leeward, chifukwa gawo lapakati lakokedwa, ndipo mtunda pakati pa mbali ya leeward ndi gawo la mbali ya mphepo wawirikiza kawiri.Ngakhale pali overvoltage, kuthekera kwa dera lalifupi pakati pa magawo ndi kochepa kwambiri.Pamene mbali ya mphepo yamkuntho imakokera kumbuyo, pali mphamvu ya capacitive yokha pansi, ndipo phokoso lopangidwa ndi lochepa kwambiri.
(3) Potseka, ndondomeko yoyendetsera ntchito imasinthidwa potseka, choyamba mutseke gawo la mbali ya mphepo, kenaka mutseke gawo la leeward, ndiyeno mutseke gawo lapakati.
(4) Kugwiritsa ntchito chubu chosungunuka ndi chinthu chokhazikika.Ngati simusamala, zingapangitse kuti kukhudzana kuyaka ndi kuyambitsa kusagwirizana, kutenthetsa kukhudzana, ndi kutulutsa masika, zomwe zimapangitsa kuti kukhudzanako kuipire kwambiri ndikupanga bwalo loipa.Choncho, pokoka ndi kutseka chubu cha fusion, gwiritsani ntchito mphamvu zochepa.Mukatseka, yang'anani mosamala kuti lilime la duckbill likhoza kumangidwa mwamphamvu kupitirira magawo awiri pa atatu a kutalika kwa lilime.Mutha kugwiritsa ntchito cholumikizira cha brake kuti mukokere bakha wakumtunda ndikukankhira pansi kangapo.Yesani kukokanso kuti muwone ngati ikukwanira bwino.Kusinthako kukatsekedwa, sikuli m'malo kapena sikutsekedwa mwamphamvu, ndipo kukakamiza kwa static kukhudzana ndi fuse sikukwanira, zomwe zingayambitse kukhudzana ndi kutentha kapena fuse chubu kugwa yokha.
