I-Unit Yomkhakha Wokugcina Umkhakha Oyingaphansi (HXGN -12)
I-Ring Main Unit yomkhakha wezulu ye-HXGN-12 iyasebenza kakhulu kwezindawo zokugcina umkhakha wokuphatha amaqhina okuqondisa ngamathuba emithandazo, amasosha, izindawo zokuhlala, izindawo zokuphatha izindlu ezide, izikolo, izindawo zokuhlela, njll. Iyasebenza ukuthola nokugcina umkhakha wokuphatha, iyasebenza kumkhakha wokuphatha omthandayo futhi kumkhakha wokuphatha wokugcina, futhi iyasebenza kuboxes bezindawo zokuphatha umkhakha.
- Ukuhlaziywa
- Imikhiqizo Econyiwe
Ithayiphe le-HXGN-12 yokugcina yezibalo zokuphakama iyasebenza kwezindawo zokuhlawula amandla we-AC esithathu ngezihlakani, nesikhundla sokubhalwa se-12kV nesikhundla sokubhalwa se-50Hz emizini, emazini, emaphakathi amahle, emabhizinisi amaningi, emasikolweni, emaparkeni, njll. Iyasebenza ukuthola nokuhlawula amandla, iyasebenza kwezindawo zokuhlawula amandla ngokugcina (ring network) nokuhlawula amandla kwezindawo zokugcina (terminal power supply), futhi iyasebenza kwezindawo zokufaka kwezindawo zokuhlawula amandla ezinkundla (box-type substations). Yilokho okusha kakhulu kwezinto zokuphakama zezibalo zokuphakama ozodingekayo ukuthinteka nokubuyisa kwemigodi yamandla.
Leli phrojekthi leli luyasebenza ngokuphelele ngemithombo yezifundo ezifana ne-IEC 298 AC Metal-Enclosed Switchgear kubani ubukhulu bevoltage obukhethekile kusuka kuma-1kV futhi kungaphansi kuma-52kV, IEC 240 High-Voltage AC Load Switch-Fuse Combinations, nangokwe-GB 3906 AC Metal-Enclosed Switchgear kubani ubukhulu bevoltage obukhethekile kusuka kuma-3kV kuya kuma-35kV, njengoba nezinye izifundo eziphambili. Kufakwe amaphuzu okugcina ukuthi akwenzeki ukuchitha okungafanele, futhi ubukhulu bekuphatha kuyiphela IP2X.
Izimo Zokusebenza
Ubusuku bokuhlunga kwesikhathi: Isilinganiso sokuqonda +40°C, isilinganiso sokuqonda -10°C.
Ubunzima bokuhlunga: Isilinganiso sesihlanu ≤ 95%, isilinganiso seminyaka ≤ 90%. Ubunzima bokuhlunga kwevapor: Isilinganiso sesihlanu ≤ 2.2×10⁻³MPa, isilinganiso seminyaka ≤ 1.0×10⁻³MPa.
Ubude bokuphakama: Akakwazi ukuphakama kune-2000m.
Isikhundla sokufakwa kufanele lisilwe kusukela kwezinkinga zokuphisa, ukuphisa kwezinkumbu, ubuncane obukhulu, ukuchitha kwezinkumbu, nokuzimisa kakhulu.
Izinto Eziphakeme
Ukusebenza kahle kakhulu kokuphepha: amasekethe okuqala nawesibili angahlukaniswa ngokuphelele; igumbi eliyinhloko le-busbar negumbi lokushintsha umthwalo lihlukaniswe ipuleti lensimbi elihlanganisiwe; kufakwa isivalo sensimbi esihlanganisiwe phakathi kwezikhala zokuxhumana ezihambayo nezingaguquguquki zesivalo som
Kulula ukufaka nokugcina, ngobukhulu obuncane nesisindo esincane ukuze kuthuthwe kalula.
Ukusebenza okulula ngamandla aphansi okusebenza; kulula ukushintsha, futhi kungashintshwa ngamunye.
Isikrini esiyinhloko singafakwa ngaphambili noma eceleni.
Ngaphezu kwezikhiphi zomthwalo we-vacuum, iswishi eyinhloko (iswishi yomthwalo) ingabuye ifakwe izikhiphi zomthwalo womoya ocindezelweyo noma igesi.
