Ubomi bethu buyanda kwaye bungenakuhlukaniswa nombane, kwayeiiseti generator dieselzisetyenziswa ngokubanzi ngakumbi ebomini. Izicelo ezahlukeneyo, iimfuno ezahlukeneyo, ziya kuyilwa ukuba zihambelane nokusetyenziswa kweekhabhinethi zokumelana nomgangatho.
Zimbini uyilo lwekhabhathi yokumelana nomhlaba yesethi ekhoyo yombane ophezulu wedizili isetiinkqubo:
1. Qwalasela ikhabhinethi yokumelana nomhlaba nganyeiseti yejenereyitha. Ikhabhinethi yokumelana nomgangatho iqukethe i-high-voltage contactor okanye i-circuit breaker, i-grounding resistance, kunye nemodyuli yokukhusela i-grounding relay. Ukuba inkqubo ihambelana, kuyimfuneko ukufakela imodyuli yokulawula ye-PLC, esetyenziselwa ukulawula i-breaker circuit of resistant ground ukuvala okanye ukuqhawula ngexesha elifanelekileyo. Ngenxa yokuba kwiinkqubo ezininzi ezihambelana noxinzelelo oluphezulu, inye kuphela uxinzelelo oluphezuluiseti yejenereyitha yediziliivumelekile ukuba ibekwe phantsi.
Izinto ezilungileyo kunye nokungalunganga: Umbane ngamnye ophezuluiseti yejenereyitha yediziliixhotyiswe ngekhabhinethi yokumelana nomhlaba, eguquguqukayo kwaye ifanelekile kwiprojekthi yokulungiswa kwakhona: inokusetyenziswa kumsebenzi omnye ngamnye.iseti yejenereyitha yedizili, kwaye ifanelekile kusetyenziso olunxuseneyo lokuphindaphindaiiseti generator diesel.
Ikwaluncedo xa udibanisa iiyunithi. Izinto ezingeloncedo zezi: kuba nganyeiseti yejenereyitha yediziliinokumelana nomhlaba, i-fault fault relay kunye ne-CT, ithatha indawo enkulu kwaye iindleko zotyalo-mali ziphezulu. Ukuba i-resistors ezimbini okanye ngaphezulu komhlaba zisekelwe ngexesha elifanayo, imodyuli yokukhusela isiseko ixhomekeke kwi-misoperation.
Ezininziiiseti generator dieselukwabelana ngokuxhathisa komhlaba, kwaye uxhulumaniso lokuxhathisa umhlaba lulawulwa yi-contactors ezininzi zombane ophezulu. Yonke le nkqubo ixhotyiswe ngekhabhinethi yokumelana nesiseko. Ikhabhinethi yokumelana nomgangatho iqukethe i-resistor yokumisa, i-multiple high voltage contactors kunye nemodyuli yokukhusela umhlaba.
Izinto eziluncedo nezingeloncedo: Zininziiiseti generator dieselukwabelana ngokuxhathisa okuqhelekileyo komhlaba, ukunciphisa utyalo-mali ekuchaseni umhlaba, ngelixa kunciphisa unyawo. Nangona kunjalo, kwiprojekthi yokuhlaziya, ukuba iiseti yejenereyitha yedizilikufuneka iqhutywe ngokwahlukileyo, kuyimfuneko yokongeza ikhabhinethi yokumelana nomhlaba.
Ijenereyitha yediziliimiyalelo yokumisela i-odolo kwikhabhathi yokumelana:
1. Amandla, amandla ombane kunye nobungakanani beyunithi yedizili;
2. izinto eziphathekayo, umbala, ubungakanani kunye nokungena kunye nokuphuma kwekhabhinethi;
3. ixabiso lokumelana, ixesha lokuhamba kunye nokuhamba ngoku;
4. Umlinganiselo we-transformer yangoku;
5. ingaba ufakele ukuxhathisa kwikhabhinethi isixhobo esweni elibukhali;
6. nokuba ufake ivacuum contactor;
7. ukuba inani leeyunithi likhulu kune-1, nokuba kufakwe isilawuli se-PLC, ukufezekisa i-inter-channel interlock.
