Malunga ne-induction yokunyibilikisa iziko lomxholo ophambili okhuselweyo, cwangcisa izizathu kunye neendlela
malunga ukuchithwa kwesithando somlilo Umxholo ophambili okhuselweyo, cwangcisa izizathu kunye neendlela
| Igama elikhuselweyo | Isizathu sokhuselo kunye nendlela yokhuseleko |
| Ubushushu bamanzi okupholisa buphezulu kakhulu | Xa iqondo lobushushu lamanzi okupholisa lingaphezulu kwexabiso elichaziweyo, kulula ukuba kubange isikali, okanye kuphume amanzi, kubangele ingozi. Ke ngoko, igeji yobushushu bamanzi ehlawulweyo inokufakwa kwindawo yokuphuma yombhobho ngamnye wokupholisa amanzi. Xa ubushushu bamanzi ekuphumeni kwayo nayiphi na isekethe yokupholisa amanzi ingaphezulu kwexabiso elivumelekileyo, kuya kukhutshwa umqondiso wealam |
| Ukupholisa uxinzelelo lwamanzi kuyehla | Xa uxinzelelo lwamanzi lwamanzi okupholisa lungaphantsi kwenani elifunekayo, iimeko zokupholisa ziya kutshatyalaliswa. Kwimibhobho ephambili yokupholisa amanzi, kukho isilinganisi soxinzelelo lwamanzi kunye nomnxeba ophilayo. Xa uxinzelelo lwamanzi luyehla ngezantsi kwexabiso elivumelekileyo, kukhutshwa isiginali yealam kwaye isekethe yokuhambisa umbane iyasikwa |
| Ngaphezulu, ukhuselo lwesekethe olufutshane | Fakela ukhuseleko olwahlula-hlukeneyo, xa isekethe ephambili inengozi engaphezulu ngoku kunye nexesha elifutshane, isekethe ephambili iyanqunyulwa kwaye kukhutshwe umqondiso wealam. |
| Phantsi kokhuseleko ombane | Phambi kwesitshixo sokuvala isixhobo sokudibanisa, ukudluliswa kwe-undervoltage relay kuqhagamshelwe. Xa isekethe engundoqo de-amandla, engundoqo lweesekethe lokuvala lwekontraka uya ngokuzenzekelayo hamba, kwaye kuya kubakho umqondiso umqondiso ingozi. Xa umnxeba olandelayo ufika, hlala |
| Isigaba C sikhusela isigaba esivulekileyo | Ekupheleni kwesixhobo sokulinganisa, kukho i-C-phase open-phase protection relay. Xa isigaba C sinqunyanyisiwe, isekethe ephambili iyanqunyulwa kwangoko, kwaye kukho umqondiso wokubonisa ukuthintela i-resonant current kwi-balance reactance kunye ne-balance capacitor circuit, eya kutshisa i-reactor kunye ne-capacitor |
| Igama elikhuselweyo | Isizathu sokhuselo kunye nendlela yokhuseleko |
| Nciphisa ukukhuselwa kwesekethe ephambili yokuvala yangoku | Kwiziko lokungeniswa, kukho inani elikhulu lembuyekezo yezincedisi kunye nokulungelelanisa ii-capacitors, eziza kuthi zenze inrush enkulu yangoku xa kuvalwa. Ke ngoko, isekethe ephambili ivaliwe kabini. Kuqala vala isinxibelelanisi sokuqala ngoxhathiso, emva koko uvale isinxibelelanisi esisebenzayo, unqumle ukuxhathisa |
| Isiguquli sobushushu beoyile kunye nokukhuselwa kwegesi | Isiguquli somlilo sombane sinesalathiso sobushushu beoyile ukujonga ubushushu beoyile. Ukukhuselwa kwegesi kufakwe kumandla amakhulu esiguquli sombane (ngaphezulu kwe-800KVA). Xa isiphoso senzeka kwaye ukudluliswa kwe-Buchholz kuya kusebenza, isekethe yokuhambisa umbane iya kunqunyulwa kwaye kukhutshwe umqondiso wealam |
| Ukhuseleko lwangaphakathi lweCapacitor yangaphakathi | Isigaba se-capacitors sokutshintsha kunye namaqondo aphakathi ombane afudumeza amandla ombane angaphantsi kwama-3000V ombane ombane onke axhumene nokukhusela i-fuse ngaphakathi. Xa naliphi na iqela le-capacitors lisilele, iqela liya kunqunyulwa ngokuzenzekelayo. |
| Iziko lokuvuza elivuzayo kunye nokukhuselwa okuphambili kwesekethe | Ukuxhotyiswa nge-alamu. Xa ukuvuza okukroliweyo kuphuma eziko okanye isekethe ephambili ibekwe, amandla ayanqunyulwa kwaye kukhutshwe isiginali yealam |
| Ukukhuselwa kombane | Faka i-absorber ephezulu kwi-voltage kwicala lesibini le-transformer ukukhusela ukusebenza kwe-voltage, i-transformer eyiprayimari kunye neyesekondari yecala kunye ne-voltage ephezulu ebangelwa yimibane |
| Ukukhusela ukukhutshwa kweCapacitor | Emva kokuba isekethe ephambili icinyiwe, i-capacitor kufuneka ikhutshelwe ukhuseleko. I-capacitor ikhutshwa ngokuzenzekelayo ngomthwalo, kwaye i-capacitor eguquguqukayo ibekwa ngokuzenzekelayo kwisekethe yokumelana nokukhupha |
