>>> Isishwankathelo seMveliso
I-XGW-12 i-series ye-switching ye-switching yangaphandle ye-intelligent-type yangaphandle ithatha isakhiwo sohlobo lwebhokisi yangaphandle kwaye iqulethe izixhobo zombane ezifana neekhabhinethi ze-SF6 ezizaliswe yigesi kunye ne-DTUs. Iyunithi ephambili yeringi iseti ye-high-voltage switchgear egcinwe kwibhokisi yentsimbi yentsimbi okanye idityaniswe kwimodyuli ye-bay-type ring main unit unit supply power. Amacandelo alo angundoqo abandakanya ukutshintshwa komthwalo kunye nabaphuli beesekethe, banikezela ngeenzuzo ezifana nesakhiwo esilula, ubungakanani obuncinci, ixabiso eliphantsi, ukuphuculwa kweeparitha zokubonelela umbane kunye nokusebenza, kunye nokhuseleko oluphuculweyo lokunikezelwa kwamandla. Isetyenziswa ngokubanzi kwizikhululo zokusasaza kunye neendawo ezincinci zohlobo lwebhokisi kumaziko omthwalo afana neendawo zokuhlala zasezidolophini, izakhiwo eziphakamileyo, izakhiwo zikawonkewonke, iifektri kunye namashishini.
Izitishi zokutshintshela ngokuqhelekileyo ziyilwe ngemigca emibini engenayo kunye nemigca emininzi ephumayo (ngokuqhelekileyo i-4 ukuya kwimigca emi-6 ephumayo). Ngokuxhomekeke kwiimfuno ezahlukeneyo, abaphuli beesekethe okanye ukutshintshwa komthwalo kunokufakwa kwimigca engenayo nephumayo. Kwiigridi zamandla ombane ophakathi, izitishi zokutshintsha ziqhele ukusetyenziselwa ukwamkela nokusasazwa kwamandla e-10kV, kwaye zixhotyiswe ngemigca ye-voltage ephakathi engenayo nephumayo, kunye nezixhobo zokusasazwa kwakhona kwamandla.
Isikhululo sokutshintsha sisixhobo sombane kunye nokuhambisa umbane esisetyenziselwa ukufumana nokusasaza umbane. Kwiigridi zamandla aphezulu, kuthiwa yi-switchyard. Uphawu lwayo kukuba i-voltage kumacala angenayo naphumayo ombane ayafana, alingana nokwandiswa kwe-substation busbar. Izixhasi zombane zisebenzisa iintambo zentambo zamacandelo amakhulu. Ingasetyenziselwa ukusombulula ingxaki yezithuba ezingeniswayo ezingenayo neziphumayo okanye iipaseji ezithintelweyo ezingenayo neziphumayo kwizikhululo ezincinci, kwaye idlala indima kwinkxaso yombane kummandla. Isetyenziselwa ukusabalalisa kunye nokudibanisa imisinga yomthwalo, ukuphazamisa i-currents short-circuit currents kunye ne-transformer no-load currents, kunye nokusingatha ukutshaja kwemijelo yemigca ephezulu kunye nemigca yentambo kumgama othile. Isebenza njengesixhobo solawulo kunye nokukhusela kwaye sisixhobo esibalulekileyo sokutshintsha unikezelo lwamandla womnatha oluphothiweyo kunye nonikezelo lwamandla ombane.
Le mveliso ihambelana nemigangatho esebenzayo: I-GB / T 11022-2020 "IiMfuno eziQhelekileyo zobuGcisa kwi-High-Voltage Switchgear kunye neMigangatho ye-Controlgear" kunye ne-GB / T 3906-2006 "3.6kV ukuya kwi-40.5kV AC Metal-Enclosed Switchgear kunye ne-Controlgear ye-IP4 ", kunye nenqanaba lokukhusela le-IP4.
