Ho tšoana le phapang pakeng tsa Ring Main Unit le Metal Clad ha e sebelisoa

Yuniti e Kholo ea Ring e sebelisoa phepelong ea motlakase ea marang-rang a ring ho hokahanya mehloli e 'meli ea motlakase kapa likarolo tsa khabinete ea switch. Mosebetsi o ka sehloohong ke ho arola likarolo tse peli, ka mosebetsi o le mong le boholo bo bonyenyane. Khabinete e bohareng ke mofuta oa khabinete ea switch e sebelisoang ke basebelisi ba ho qetela, e nang le mesebetsi e felletseng le bophahamo bo boholo. Ho na le mefuta e mengata ea likhabinete tse bohareng, tse ka aroloang ka likhabinete tsa switch tse kenang le tse tsoang, likhabinete tsa metering, likhabinete tsa transformer, le likhabinete tsa transformer tse sebelisitsoeng. Li-switch tse likhabineteng tse bohareng li ka hlomelloa ka lisebelisoa tsa tšireletso tse iketsang. Haeba ho ka ba le kotsi, sesebelisoa sa tšireletso se romela lets'oao la ho etsa switch. Ketso e ea sitisa le ho khaola phepelo ea motlakase. Bongata ba li-breaker tsa potoloho ea vacuum tsa VS1 li sebelisoa ka khabineteng. Ka lebaka la ts'ebeliso e fapaneng, sebopeho le khetho ea likarolo tsa tse peli li fapane haholo.

Sistimi ea phepelo ea motlakase le kabo, ho lokela ho etelloa pele ho metering ea phepelo e phahameng ho feta metering ea motlakase o tlase; metering ea motlakase o tlase e ka nahanoa feela ha ho se na mokhoa oa ho kenya metering lehlakoreng le nang le motlakase o phahameng; ka nako ena, khabinete ea metering ea motlakase o tlase e lokela ho beoa lehlakoreng la "ka pele". , Ke hore, karolo e ka pele ea mohala o kenang oa motlakase o tlase le ka morao ho transformer, empa khabinete ea metering e ke ke ea ba tlas'a tšireletso ea khabinete ea mohala o kenang oa motlakase o tlase, kahoo maemong a tloaelehileng, e lokela ho ba tlas'a tšireletso ea switch ea motlakase o phahameng ea transformer. Tabeng ena, khabinete ea marang-rang a ring le khabinete e bohareng li ka sebelisoa.

Hona jwale, Ring Main Unit ha e na ho hlomelloa feela ka disebediswa tsa motlakase tse kopantsweng le switch-fuse, empa hape le di-circuit breaker, tse kang XGN ya lapeng, Schneider's SM6, Siemens 8DJH, ABB's SAFE, jj., mme tshireletso ya bobedi e ka hlomelloa ka sesebediswa sa tshireletso ya microcomputer. Leha ho le jwalo, circuit breaker e kentsweng yuniting ya ring main e na le moedi wa mojaro, mme meedi ya ring main unit ya moetsi ka mong e fapane. Jwalo ka Schneider RM6 Ring Main Unit, tshireletso ya switch ya high-voltage ya transformer e kgolo ho feta kapa e lekana le 2000KVA, mme tshireletso ya circuit breaker + VIP300 microcomputer e tlameha ho sebediswa. Mojaro meleng e kenang le e tswang ya khabinete e bohareng ha o thibelwe.

Ehlile, ka nts'etsopele ea theknoloji ea hona joale ea phepelo ea motlakase, mefuta ena ka bobeli ea likhabinete e ntlafetse haholo. Likhabinete tse bohareng li ntse li fokola haholo; Yuniti e Kholo ea Ring e ntse e sebetsa haholoanyane; empa ka kakaretso, likhabinete tse bohareng li sebelisoa. Mosebelisi oa ho qetela ke lisebelisoa tsa taolo, empa theko ea eona e phahame haholo; khabinete ea marang-rang a ring e ne e etselitsoe qalong ho rarolla bothata ba phepelo ea motlakase le kenyelletso, 'me mosebetsi oa eona o bonolo, empa sebopeho sa eona se bonolo, bophahamo ba modumo bo bonyenyane, 'me theko e tlase haholo. Haufinyane, mesebetsi e ntse e atolosoa khafetsa, haholo-holo boholo ba eona bo bonyenyane bo bonolo ho kenngoa ka har'a "phetoho ea lebokose", kahoo e na le nts'etsopele e ntle haholo; hajoale Yuniti e Kholo ea Ring ha e sebelisoe feela e le khabinete ea switch ea ho ikopanya, empa hape e ka sebelisoa e le switch ea loop in and loop out Cabinet, metering cabinet, PT cabinet.
Ka hona, ha re bua ka ho khetheha, hore na tse peli li ka fapanyetsanoa, ka lebaka la ho se tsitse ha mesebetsi le ts'ebetso ea lihlahisoa tsa bahlahisi ba fapaneng, ha ho bonolo ho bolela. Mabapi le phokotso ea litšenyehelo, khabinete ea marang-rang a lesale e na le melemo e itseng. Ka nts'etsopele ea theknoloji ea yuniti ea lesale e kholo, ts'ebeliso ea yuniti ea lesale e kholo le khabinete ea bohareng e ka kopana ka makhetlo a mangata. Empa tsamaisong ea kabo ea matla a phahameng a motlakase o nang le maqhubu a maholo a kaholimo ho 1250A, khabinete ea lesale e kholo e ke ke ea nkela khabinete ea bohareng sebaka.
