Uhlaka lwekhabhinethi oluyisisekelo lwe-switchgear ene-voltage ephansi luyisakhiwo esihlanganisiwe sokuhlangana. Zonke izingxenye zesakhiwo sekhabhinethi zihlanganiswe nge-galvanized, zixhunywe ngokuqinile ngezikulufo zokukhiya ezizithintayo noma izikulufo ezine-hexagonal zebanga elingu-8.8 ukuze zakhe uhlaka lwekhabhinethi oluyisisekelo. Ngemuva kwalokho, ngokwezidingo zezinguquko zeskimu, iminyango ehambisanayo, amapuleti okuvala, izingxenye, amabakaki okufaka, amabha, amayunithi asebenzayo nezinye izingxenye kuyangezwa ukuze kuhlanganiswe i-switchgear ephelele ene-voltage ephansi. Ubukhulu bezingxenye kanye nezingxenye ku-switchgear buhlanganisiwe (iyunithi ye-modulus E = 25mm, efanayo ngezansi).
1. Isikhungo sokusabalalisa amandla (esibizwa nge-PC)
● Ikhabhinethi ye-PC ihlukaniswe izingxenye ezine, okungukuthi indawo yebhasi evundlile, ngemuva kwekhabhinethi; Indawo yeyunithi esebenzayo ingaphezulu kwekhabhinethi noma ohlangothini lwesobunxele lwekhabhinethi; Indawo yekhebula, engxenyeni engezansi yangaphambili yekhabhinethi noma engxenyeni yesokudla yangaphambili yekhabhinethi: indawo yesekethe yokulawula, engxenyeni engenhla yangaphambili yekhabhinethi.
Izindlela zokuhlukanisa: kusetshenziswa amaphaneli e-melamine phenolic sandwich noma amapuleti ensimbi phakathi kwegumbi le-busbar elivundlile kanye negumbi leyunithi esebenzayo. Igumbi lesekethe yokulawula kanye negumbi leyunithi esebenzayo zihlukaniswe yigobolondo le-polyurethane foam elibunjiwe lepulasitiki elivimbela ilangabi. Igumbi leyunithi esebenzayo ngakwesobunxele kanye negumbi lesistimu kagesi ngakwesokudla zihlukaniswe yipuleti lensimbi.
● Ama-circuit breaker afakwe ku-cabinet angasetshenziswa ngesandla ngaphandle kwe-cabinet uma umnyango uvaliwe.Hlola isimo sokuvula nokuvala kwe-circuit breaker bese unquma ukuthi i-circuit breaker isendaweni yokuhlola noma endaweni yokusebenza ngokuya ngobudlelwano besimo phakathi kwendlela yokusebenza nomnyango.
● Isekethe eyinhloko kanye nesekethe eyisizayo zakhiwe njengesakhiwo sokuhlukanisa. Amayunithi esekethe eyisizayo akhiwe ngamathuluzi, izibani zesignali kanye nezinkinobho konke kufakwe ebhodini lepulasitiki. Kukhona isembozo esenziwe ngepulasitiki ye-polyurethane foam evimbela ilangabi ngemuva kwebhodi. Ihlukile kwisekethe eyinhloko.
2.Ngesikhungo sokulawula imoto esidonsekayo kanye nesikhungo sokusabalalisa amandla aphansi (okuzobizwa ngokuthi yi-MCC edonsekayo)
● Ikhabhinethi ye-MCC edonsekayo ihlukaniswe ngamakamelo amathathu okuhlukaniswa, okungukuthi, indawo yebhasi evundlile ngemuva kwekhabhinethi, indawo yeyunithi esebenzayo ohlangothini lwesobunxele lwangaphambili lwekhabhinethi, kanye nendawo yekhebula ohlangothini lwesokudla lwangaphambili lwekhabhinethi. Indawo yebhasi evundlile kanye nendawo yeyunithi esebenzayo zihlukaniswe udonga olusebenzayo olwenziwe ngepulasitiki ye-foam evimbela umlilo, kanti indawo yekhebula ihlukaniswe yipuleti lensimbi endaweni yebhasi evundlile kanye nendawo yeyunithi esebenzayo.
●I-MCC ekhishwayo inezakhiwo ezimbili: ukusebenza ohlangothini olulodwa kanye nokusebenza ohlangothini oluphindwe kabili.
● I-MCC ekhishwayo inosayizi abahlanu abajwayelekile bamadrowa, okungu-8E/4,8E/2,8E,16E kanye no-24E ngokulandelana. Izakhiwo zamadrowa angu-8E/4 kanye no-8E/2 ziyizingxenye zepulasitiki ezibunjiwe ezivimbela ilangabi kanye namaphrofayili e-aluminium alloy (ama-pcs angu-4 angu-8E/4 noma ama-pcs amabili angu-8E/2 akha isikhawu sokuphakama esingu-8E). Ukuphakama okuphelele kwegumbi leyunithi esebenzayo kungu-72E.
● Osayizi abahlanu abajwayelekile bamadrowa ngokuvamile banezixhumanisi eziyi-16 zokuhlukaniswa zesibili eziphumayo. Uma kudingeka, ngaphandle kwedrowa engu-8E/4, amanye amadrowa amane angandiswa abe ngu-32. Amatheminali okuxhumana ngakunye okuqinile angaxhunywa ngezintambo ezi-3 ngesikhathi esisodwa. Amatheminali angenhla anikezwa umenzi ngezesekeli ezifanele kanye ne-cold rolling pliers nomkhiqizo.
● Ngenqubo yokusebenza kwedivayisi yokuxhumanisa ngomshini, idrowa lingasuswa kuphela uma isekethe eyinhloko kanye nesekethe eyisizayo konke kunqanyuliwe. Idivayisi yokuxhumanisa ngomshini yenza idrowa ibe nendawo yokuhamba, indawo yokuphuka kanye nendawo yokuhlukanisa, futhi iziphawule ngezimpawu ezihambisanayo.
Isibambo sokusebenza kudivayisi yokuxhumanisa ngomshini kanye nesibambo sokusebenza se-circuit breaker eyinhloko singavalwa ngezingidi ezintathu ngesikhathi esisodwa.
3. Isikhungo sokulawula izimoto esinyakazayo kanye nesikhungo esincane sokusabalalisa amandla kagesi (esibizwa ngokuthi i-MCC enyakazayo)
● Izici zesakhiwo sekhabhinethi se-MCC eshukumayo zifana ne-(a) kanye ne-(b) esigabeni 4.2.
● Iyunithi esebenzayo yakhelwe njengesakhiwo esinyakazayo. Ukuxhumana phakathi kweyunithi esebenzayo nebha yebhasi eqondile kusebenzisa ukuxhumana okuyinhloko kokuzihlukanisa. Ngisho noma isekethe exhunywe kuyo ibukhoma, iyunithi esebenzayo ingakhishwa ngokuphelele emishinini bese ibuyiselwa emuva. Esinye isiphetho isakhiwo esiqinile.
Amayunithi asebenzayo e-MCC ahlukaniswe ngama-compartment amayunithi asebenzayo angu-3E, 6E, 8E, 16E, 24E kanye no-40E, kanti ukuphakama okuphelele nakho kungu-72E.
4. Uhlelo lwebha yebhasi
● Ibha yebhasi evundlile (L1,L2,L3). Ibha yebhasi evundlile ifakwe endaweni yebha yebhasi ezimele ngemuva kwekhabhinethi. Inezindawo ezimbili zokufaka ongazikhetha, okungukuthi, i-1/3 noma i-2/3 yokuphakama kwekhabhinethi. Ibha yebhasi ingafakwa engxenyeni engenhla noma engezansi njengoba kudingeka, amaqembu aphezulu naphansi nawo angafakwa ngesikhathi esifanayo. Amasethi amabili ebha yebhasi angasetshenziswa ngokwehlukana noma ngokuhambisana.
Ibha yebhasi yesigaba ngasinye iqukethe amabha ebhasi angu-2, 4 noma angu-8 axhunywe ngokufana, kanti izingxenye zebha yebhasi zinezinhlobo eziyisithupha ze-10x30x2,10x60×2,10x80x2,10×60x4,10x80x2x2 kanye ne-10×60x4×2.
● Ibhasi eliqondile eliyi-L eliyi-busbar yethusi elinobukhulu obungu-50x30x5, elifakwe odongeni olusebenzayo olwenziwe ngepulasitiki evimbela ilangabi, futhi izinga lokuvikela lengxenye ephilayo lifinyelela ku-IPp20.
● Intambo engathathi hlangothi (ucingo lwe-N) kanye nentambo yokumisa evikelayo (ucingo lwe-PE). I-busbar yentambo engathathi hlangothi kanye ne-busbar yentambo yokumisa evikelayo ifakwa ngokuhambisana engxenyeni engezansi yegumbi leyunithi esebenzayo futhi iqonde ngqo egumbini lekhebula. Uma intambo ye-N kanye nentambo ye-PE zihlukaniswe yi-insulator, intambo ye-N kanye nentambo ye-PE kusetshenziswa ngokwehlukana. Uma zombili zifinyeziwe ngama-conductor, intambo ye-PEN izokwakhiwa.
5.Uhlelo lokuvikela isisekelo
Isekethe yokuvikela yalesi switchgear inezingxenye ezimbili: ucingo lwe-PE (noma i-PEN) olufakwe ngokwehlukana futhi luhamba ngobude bonke bokuhlela kanye nezingxenye zesakhiwo sensimbi esiqhubayo. Ngaphandle komnyango wangaphandle kanye nepuleti lokuvala, ezinye izingxenye zesakhiwo sensimbi zifakwe ethini. Ukuxhumeka kwesakhiwo kuklanywe ngokucophelela ukuze kuvumeleke ukuthi kudlule ugesi othile we-short-circuit.
6. Ithreyi yekhebula lesekethe elisizayo
Ithreyi yekhebula lesekethe elisizayo lifakiwe phezulu kwegumbi leyunithi esebenzayo, futhi imigqa yokuxhumanisa phakathi kwamakhabethe nezintambo zikagesi zomphakathi ingafakwa kuthreyi.
7. Izinyathelo zokuhlukanisa izifunda ezisizayo
Kumjikelezo ngamunye wohlelo lwe-MCC olukhishwayo, i-transformer yokuhlukanisa ingafakwa ngokwezidingo zesistimu. Amandla e-transformer aphezulu kune-contactor ye-AC, futhi imininingwane iyanqunywa.
