Mayelana nokungeniswa kokuncibilika kwesithando okuqukethwe okuyisisekelo esivikelekile, izimbangela nezindlela
Mayelana ukuchithwa kwesithando somlilo okuqukethwe okuyinhloko okuvikelwe, setha izimbangela nezindlela
Igama elivikelwe | Isizathu sokuvikela nendlela yokuvikela |
Izinga lokushisa lamanzi elipholile liphakeme kakhulu | Lapho izinga lokushisa lamanzi okupholisa lidlula inani elibekiwe elivumelekile, kulula ukudala isikali, noma ngisho ukuhwamukisa amanzi, kubangele ingozi. Ngakho-ke, igeji lokushisa kwamanzi elikhokhisiwe lingafakwa lapho kuphuma khona ipayipi ngalinye lokupholisa amanzi. Lapho izinga lokushisa lamanzi ekuphumeni kwanoma isiphi isifunda samanzi okupholisa lidlula inani elivumelekile, kuzokhishwa isignali ye-alamu |
Ukucindezela kwamanzi okupholisa kwehla | Lapho ingcindezi yamanzi yamanzi okupholisa ingaphansi kwenombolo edingekayo, izimo zokupholisa zizobhujiswa. Epayipini lokungena lamanzi elipholile eliphambili, kunegeji yokucindezela amanzi enokuxhumana bukhoma. Lapho ingcindezi yamanzi yehla ngaphansi kwenani elivumelekile, kukhishwa isignali ye-alamu bese kunqanyulwa isekethe yokuphakela ugesi inzwa |
Ngaphezulu kwamanje, ukuvikelwa kwesifunda okufushane | Faka okokuvikela okuhlukile kokudluliswa kwamanje, lapho isekethe enkulu iba nengozi eyeqile manje neyesikhashana, isifunda esikhulu siyanqunywa futhi kukhishwa isignali ye-alamu |
Ngaphansi kokuvikelwa kwamandla | Phambi kwesixhumi esikhulu sokuvala isekethe, i-relvvtage relay ixhunyiwe. Lapho isifunda esiyinhloko singekho amandla, isixhumi esikhulu sokuvala isekhethi sizokhubeka ngokuzenzekelayo, futhi kuzoba nenkomba yesiginali yengozi. Lapho ucingo olulandelayo lufika, hlala eceleni |
Isigaba C ukuvikelwa kwesigaba esivulekile | Ekupheleni kwesitolo sedivayisi yokulinganisa, kukhona i-C- phase open-phase protection relay. Lapho isigaba C sinqunyiwe, isifunda esikhulu sinqunywa ngokushesha, futhi kunesibonakaliso sesiginali sokuvimbela ukuguquguquka kwamanje ku-reaction ye-balance kanye ne-balance capacitor circuit, ezoshisa i-reactor balance ne-capacitor |
Igama elivikelwe | Isizathu sokuvikela nendlela yokuvikela |
Khawulela ukuvikelwa kwamanje wesekethe wokuvala wamanje | Esithandweni sokungeniswa, kunenani elikhulu lama-capacitors wesinxephezelo nama-capacitors wokulinganisa, azokhiqiza amandla amakhulu wokungena lapho kuvalwa. Ngakho-ke, isifunda esikhulu sivaliwe kabili. Okokuqala vala oxhumana naye oqala ukumelana nemishini, bese uvale oxhumana naye osebenzayo, bese usika ukumelana nakho |
Inkomba yokushisa kawoyela weTransformer nokuvikelwa kwegesi | Isishintshi somlilo kagesi sinenkomba yokushisa kawoyela yokuqapha izinga lokushisa kukawoyela. Ukuvikelwa kwegesi nakho kufakwe kumthamo omkhulu wesithombisi somlilo kagesi (ngaphezulu kwe-800KVA). Lapho iphutha livela futhi ukudluliswa kwe-Buchholz kuzosebenza, isekethe yokuphakelwa kukagesi izonqanyulwa bese kukhishwa isignali ye-alamu |
Ukuvikelwa kwangaphakathi ngokweqile kwe-Capacitor | Ama-capacitors wokushintsha kwesigaba kanye nama-capacitors wokushisa kagesi aphakathi nendawo angaphansi kwama-3000V amandla wamandla konke kuxhumene nokuvikelwa kwe-fuse okwedlulele ngaphakathi. Lapho noma yiliphi iqembu lama-capacitors lihluleka, iqembu lizonqunywa ngokuzenzekelayo. |
I-Crucible leakage furnace kanye nokuvikelwa kwesekethe okuyinhloko | Ifakwe i-alamu yedivayisi ye-crucible. Lapho ukuvuza okubethelekayo kuphuma esithandweni somlilo noma isifunda esiyinhloko sisekiwe, amandla ayanqunywa futhi kukhishwa isignali ye-alamu |
Ukuvikelwa okweqile | Faka isifunxi esingaphezu kwamandla kagesi ohlangothini lwesibili lwe-transformer ukuvikela ukusebenza kwamandla kagesi amaningi, ukuwohloka kohlangothi olusezingeni eliphakeme nolwesibili namandla angaphezulu kwamandla adalwe yimibani yombani |
Ukuvikelwa kokukhishwa kwe-Capacitor | Ngemuva kokuthi kucishwe isekethe enkulu, i-capacitor kufanele ikhishwe ukuze iphephe. I-capacitor ikhishwa ngokuzenzakalela ngomthwalo, futhi i-capacitor eguquguqukayo ibekwa ngokuzenzakalela kumjikelezo wokumelana nokukhishwa |
