Isakhelo sekhabhinethi esisisiseko seswitshi se-low-voltage sisakhiwo esidibeneyo sokuhlanganisa. Zonke iindawo zesakhelo sekhabhinethi zigqunywe nge-galvanized, ziqhagamshelwe ngokuqinileyo ngokusebenzisa izikrufu zokuzitshixa ezizicofayo okanye izikrufu ze-hexagonal ze-grade 8.8 ukwenza isakhelo sekhabhinethi esisisiseko. Emva koko, ngokweemfuno zotshintsho lweskimu, iingcango ezihambelanayo, iipleyiti zokutywina, izahlulo, iibrakethi zokufakela, iibhasi, iiyunithi ezisebenzayo kunye nezinye iindawo zongezwa ukudibanisa iswitshi epheleleyo ye-low-voltage. Ubukhulu beendawo kunye neendawo kwiswitshi zihlengahlengiswa (iyunithi yemodulus E = 25mm, efanayo ngezantsi).
1. Iziko losasazo lwamandla (eliya kubizwa ngokuba yiPC)
● Ikhabhinethi yePC yahlulwe yangamacandelo amane, oko kukuthi, icandelo lebhasi elithe tye, ngasemva kwekhabhinethi; Icandelo leyunithi esebenzayo likwinxalenye ephezulu yangaphambili yekhabhinethi okanye kwicala lasekhohlo ngaphambili kwekhabhinethi; Icandelo lekhebula, kwinxalenye esezantsi yangaphambili yekhabhinethi okanye kwinxalenye ekunene yangaphambili yekhabhinethi: icandelo lesekethe yokulawula, kwinxalenye ephezulu yangaphambili yekhabhinethi.
Amanyathelo okwahlula: iiphaneli zesandwich ze-melamine phenolic okanye iipleyiti zentsimbi zisetyenziswa phakathi kwecandelo le-busbar elithe tye kunye necandelo leyunithi esebenzayo. Icandelo lesekethe yokulawula kunye necandelo leyunithi esebenzayo zahlulwe yigobolondo yesitywina esenziwe nge-polyurethane foam yeplastiki egqunyiweyo ethintela ilangatye. Icandelo leyunithi esebenzayo ekhohlo kunye necandelo lenkqubo yombane ekunene zahlulwe yipleyiti yentsimbi.
● Ii-circuit breakers zekhabhinethi ezifakwe kwikhabhinethi zingasetyenziswa ngesandla ngaphandle kwekhabhinethi xa ucango luvaliwe. Jonga imeko yokuvulwa nokuvalwa kwe-circuit breaker kwaye umisele ukuba i-circuit breaker ikwindawo yovavanyo okanye kwindawo yokusebenza ngokwendawo edibeneyo phakathi kwendlela yokusebenza kunye nocango.
● Isekethe ephambili kunye nesekethe encedisayo zenzelwe ukuba zibe sakhiwo sokwahlulahlula. Iiyunithi zesekethe encedisayo ezenziwe ngezixhobo, izibane zesignali kunye namaqhosha zonke zifakwe kwibhodi yeplastiki. Kukho isigqubuthelo esenziwe ngeplastiki ye-polyurethane foam ethintela ilangabi emva kwebhodi. Yahlukile kwisekethe ephambili.
2. Ngeziko lolawulo lweemoto ezitsalwayo kunye neziko losasazo lwamandla aphantsi (ekubhekiswa kulo apha njenge-MCC etsalwayo)
● Ikhabhinethi ye-MCC enokutsalwa yahlulwe yangamagumbi amathathu okuzahlula, oko kukuthi, indawo yebhasi ethe tye ngasemva kwekhabhinethi, indawo yeyunithi esebenzayo kwicala lasekhohlo langaphambili lekhabhinethi, kunye nendawo yekhebula kwicala lasekunene langaphambili lekhabhinethi. Indawo yebhasi ethe tye kunye nendawo yeyunithi esebenzayo zahlulwe ludonga olusebenzayo olwenziwe ngeplastiki yefoam ethintela ilangabi, kwaye indawo yekhebula yahlulwe yipleyiti yentsimbi ukusuka kwindawo yebhasi ethe tye kunye nendawo yeyunithi esebenzayo.
●I-MCC enokutsalwa inezakhiwo ezimbini: ukusebenza kwicala elinye kunye nokusebenza kwicala elinye.
● I-MCC enokutsalwa inee-drawer ezihlanu ezisemgangathweni, eziyi-8E/4,8E/2,8E,16E kunye ne-24E ngokwahlukeneyo. Izakhiwo zee-drawer ze-8E/4 kunye ne-8E/2 zizinto zeplastiki ezibunjiweyo ezithintela ilangatye kunye neeprofayili ze-aluminium alloy (ii-4 ze-8E/4 okanye ii-2 ze-8E/2 ezenza isithuba sokuphakama kwe-8E). Ukuphakama okupheleleyo kwecandelo leyunithi esebenzayo yi-72E
● Iidrowa ezisemgangathweni ezintlanu zihlala zineendawo zokunxibelelana zesibini ezili-16 eziphumayo. Ukuba kuyimfuneko, ngaphandle kwedrowa ye-8E/4, ezinye iidrowa ezine zingandiswa ziye kwi-32. Iiterminal zoqhagamshelwano ngalunye oluzinzileyo zinokudityaniswa ngeentambo ezi-3 ngaxeshanye. Ezi terminal zingasentla zibonelelwa ngumvelisi ngezixhobo ezifanelekileyo kunye neepliers eziqengqelekayo ezibandayo kunye nemveliso.
● Ngokusebenzisa inkqubo yokusebenza kwesixhobo sokuqhagamshela ngoomatshini, idrowa inokushukunyiswa kuphela xa isekethe ephambili kunye nesekethe encedisayo zonke ziqhawukile. Isixhobo sokuqhagamshela ngoomatshini senza idrowa ibe nendawo yokuhamba, indawo yokuqhekeka kunye nendawo yokwahlula, kwaye iziphawule ngeempawu ezihambelanayo.
Isiphatho sokusebenza kwisixhobo sokuqhagamshela ngoomatshini kunye nesiphatho sokusebenza se-circuit breaker ephambili sinokutshixwa ngee-padlocks ezintathu ngaxeshanye.
3. Iziko lolawulo lweemoto ezishukumayo kunye neziko elincinci lokusasaza amandla angoku (ekubizwa ngokuba yi-MCC eshukumayo)
● Iimpawu zesakhiwo sekhabhinethi se-MCC eshukumayo ziyafana ne(a) kunye(b)kwisiqendu 4.2.
● Iyunithi esebenzayo yenzelwe ukuba ibe sisakhiwo esinokushukuma. Unxibelelwano phakathi kweyunithi esebenzayo kunye ne-busbar ethe nkqo lusebenzisa uqhagamshelwano oluphambili lokwahlukanisa. Nokuba isekethe eqhagamshelwe kuyo iyasebenza, iyunithi esebenzayo inokukhutshwa ngokupheleleyo kwisixhobo ize ibuyiselwe. Esinye isiphelo sisakhiwo esizinzileyo.
Iiyunithi ezisebenzayo ze-MCC ezishukumayo zahlulwe zibe zii-compartments zeyunithi ezisebenzayo ze-3E,6E,8E,16E,24E kunye ne-40E, kwaye ukuphakama okupheleleyo kukwayi-72E.
4. Inkqubo yebhasi
● Ibhasi ethe tye (L1,L2,L3). Ibhasi ethe tye ifakwe kwindawo yebhasi ezimeleyo emva kwekhabhinethi. Ineendawo ezimbini zokufakela onokukhetha kuzo, oko kukuthi, i-1/3 okanye i-2/3 yokuphakama kwekhabhinethi. Ibhasi ingafakwa kwindawo ephezulu okanye esezantsi njengoko kufuneka, amaqela aphezulu nasezantsi nawo angafakwa ngaxeshanye. Iiseti ezimbini zebhasi zingasetyenziswa ngokwahlukeneyo okanye ngaxeshanye.
Ibha yebhasi yesigaba ngasinye ineebha zebhasi ezi-2, 4 okanye ezi-8 ezidityaniswe ngaxeshanye, kwaye iindawo ezinqamlezileyo zebha yebhasi zineentlobo ezintandathu ze-10x30x2, 10x60×2, 10x80x2, 10×60x4, 10x80x2x2 kunye ne-10×60x4×2.
● Ibhasi ethe nkqo i-busbar enomfanekiso we-L ibhasi yobhedu ene-50x30x5, efakwe eludongeni olusebenzayo olwenziwe ngeplastiki ethintela ilangabi, kwaye inqanaba lokhuseleko lwenxalenye ephilayo lifikelela kwi-IPp20.
● Ucingo olungathathi cala (ucingo lwe-N) kunye nocingo olukhuselayo lokumisa umhlaba (ucingo lwe-PE). I-busbar yentambo engathathi cala kunye ne-busbar yentambo yokumisa umhlaba ekhuselayo zifakelwe ngaxeshanye kwicandelo elisezantsi leyunithi esebenzayo kwaye ngokuthe nkqo kwindawo yekhebula. Ukuba ucingo lwe-N kunye nocingo lwe-PE zahlulwe zi-insulators, ucingo lwe-N kunye nocingo lwe-PE zisetyenziswa ngokwahlukeneyo. Ukuba zombini zifinyezwe zii-conductors, ucingo lwe-PEN luya kwenziwa.
5Inkqubo yokukhusela umhlaba
Isekethe yokukhusela yale switchgear inamacandelo amabini: ucingo lwe-PE (okanye i-PEN) olufakwe ngokwahlukeneyo kwaye luhamba kubude bonke bolungiselelo kunye neendawo zesakhiwo sesinyithi esiqhubayo. Ngaphandle kocango lwangaphandle kunye nepleyiti yokutywina, ezinye iindawo zesakhiwo sesinyithi zifakwe kwiitini. Uqhagamshelo lwesakhiwo luyilwe ngononophelo ukuvumela ukuba sidlule umsinga othile wesekethe emfutshane.
6.Itreyi yentambo yesekethe encedisayo
Itreyi yekhebula yesekethe encedisayo ifakwe phezulu kwecandelo leyunithi esebenzayo, kwaye imigca yokudibanisa phakathi kweekhabhathi kunye neentambo zombane zikawonke-wonke ingafakwa kwitreyi.
7. Amanyathelo okwahlula iisekethe ezincedisayo
Kwisekethe nganye yeskimu se-MCC esikhutshwayo, i-transformer yokwahlula ingafakwa ngokweemfuno zenkqubo. Umthamo we-transformer uphezulu kunowe-AC contactor, kwaye iinkcukacha ziyamiselwa.
