Zomwezo ndi kusiyana pakati pa Ring Main Unit ndi Metal Clad pogwiritsira ntchito

Chipinda Chachikulu cha Ring chimagwiritsidwa ntchito mu netiweki yamagetsi ya ring kuti chilumikize magwero awiri amagetsi kapena magawo a kabati yosinthira. Ntchito yayikulu ndikugawa magawo awiriwa, ndi ntchito imodzi ndi yaying'ono. Kabati yapakati ndi mtundu wa kabati yosinthira yomwe imagwiritsidwa ntchito ndi ogwiritsa ntchito kumapeto, yokhala ndi ntchito zonse komanso voliyumu yayikulu. Pali mitundu yambiri ya makabati apakati, omwe amatha kugawidwa m'makabati osinthira olowera ndi otuluka, makabati oyezera, makabati osinthira, ndi makabati osinthira ogwiritsidwa ntchito. Ma switch omwe ali m'makabati apakati amatha kukhala ndi zida zodzitetezera zokha. Pakachitika ngozi, chipangizo choteteza chimatumiza chizindikiro kuti chipange switch. Ntchito imagunda ndikudula magetsi. Ambiri mwa ma vacuum circuit breakers a VS1 amagwiritsidwa ntchito mu kabati. Chifukwa cha ntchito zosiyanasiyana, kapangidwe ndi kusankha kwa zigawo ziwirizi ndizosiyana kwambiri.

Mu dongosolo la magetsi ndi kugawa, kuyenera kuperekedwa patsogolo pa kuyeza magetsi okwera m'malo moyeza magetsi otsika; kuyeza magetsi otsika kungaganizidwe kokha ngati palibe njira yokhazikitsira kuyeza magetsi kumbali ya magetsi okwera; panthawiyi, kabati yoyezera magetsi otsika iyenera kuyikidwa mbali "yakutsogolo". , Ndiko kuti, kutsogolo kwa mzere wolowera wamagetsi otsika ndi kumbuyo kwa transformer, koma kabati yoyezera magetsi singakhale pansi pa chitetezo cha kabati yolowera yamagetsi otsika, kotero nthawi zonse, iyenera kukhala pansi pa chitetezo cha switch yamagetsi okwera ya transformer. Pankhaniyi, kabati ya netiweki ya mphete ndi kabati yapakati zingagwiritsidwe ntchito.

Pakadali pano, Ring Main Unit siingokhala ndi zida zamagetsi zophatikizana ndi load switch-fuse, komanso zotchingira ma circuit, monga XGN yakunyumba, Schneider's SM6, Siemens 8DJH, ABB's SAFE, ndi zina zotero, ndipo chitetezo chachiwiri chingakhale ndi chipangizo choteteza ma microcomputer. Komabe, circuit breaker yomwe yayikidwa mu ring main unit ili ndi malire a katundu, ndipo malire a ring main unit ya wopanga aliyense ndi osiyana. Monga Schneider RM6 Ring Main Unit, chitetezo cha switch ya transformer yamagetsi okwera ndi akulu kuposa kapena ofanana ndi 2000KVA, ndipo circuit breaker + VIP300 microcomputer protection iyenera kugwiritsidwa ntchito. Katundu pamizere yolowera ndi yotuluka ya cabinet yapakati siwoletsedwa.

Zachidziwikire, ndi chitukuko cha ukadaulo wamagetsi womwe ulipo, mitundu yonse iwiri ya makabati yakula kwambiri. Makabati apakati akucheperachepera; Ring Main Unit ikugwira ntchito kwambiri; koma kawirikawiri, makabati apakati amagwiritsidwa ntchito mu. Wogwiritsa ntchito womaliza ndiye zida zowongolera, koma mtengo wake ndi wokwera kwambiri; ring network cabinet idapangidwa poyamba kuti ithetse vuto la magetsi ndi kuyambitsa, ndipo ntchito yake ndi yosavuta, koma kapangidwe kake ndi kosavuta, voliyumu ndi yaying'ono, ndipo mtengo wake ndi wotsika. Posachedwapa, ntchito zake zakhala zikukulitsidwa nthawi zonse, makamaka kukula kwake kochepa ndikosavuta kuyika mkati mwa "box change", kotero ili ndi chitukuko chabwino kwambiri; pakadali pano Ring Main Unit siigwiritsidwa ntchito ngati contact switch cabinet yokha, komanso ingagwiritsidwe ntchito ngati loop in and loop out switch Cabinet, metering cabinet, PT cabinet.
Chifukwa chake, makamaka, kaya ziwirizi zitha kusinthidwa, chifukwa cha kusagwirizana kwa ntchito ndi magwiridwe antchito a zinthu za opanga osiyanasiyana, sizophweka kunena. Ponena za kuchepetsa ndalama, kabati ya netiweki ya mphete ili ndi zabwino zina. Ndi chitukuko cha ukadaulo wa ring main unit, kugwiritsa ntchito ring main unit ndi center cabinet kumatha kuyanjana nthawi zambiri. Koma mu dongosolo logawa mphamvu zamagetsi amphamvu kwambiri lomwe lili ndi mafunde akuluakulu opitilira 1250A, kabati yayikulu ya mphete silingalowe m'malo mwa kabati yapakati.
