I-Gas-insulated switchgear (GIS) iye yaguqula iinkqubo zokuhambisa amandla ngokubonelela nge-insulation ephezulu kunye neempawu zokucima i-arc. Ngokusebenzisa igesi yesulfure ye-hexafluoride njengendlela yokugquma kunye ne-arc-quenching medium, i-GIS yenza ukuba kuhlanganiswe kunye noyilo lwe-switchgear encinci. Kule bhlog, siza kuphonononga izibonelelo zokwamkela isisombululo se-35kv 1250A GIS, kubandakanywa ukuthembeka okuphezulu, ukhuseleko, uyilo oluzimeleyo lwemodyuli kunye nokulula kwesicelo.
Uyilo oludityanisiweyo olulungiselelwe isithuba:
I-GIS ithatha ithuba leepropati ezibalaseleyo zokugquma kwegesi yesulfure ye-hexafluoride ukunciphisa kakhulu ubungakanani bekhabhinethi yokutshintsha. Olu yilo lubambeneyo longa indawo kwiindawo zasezidolophini. Ubungakanani obubambeneyo be-GIS switchgear buyenza ibe lukhetho olufanelekileyo kwiimeko zokuhambisa amandla oxinaniso oluphezulu.
Ukuthembeka okuphezulu kunye nokhuseleko:
Enye yeenzuzo eziphambili ze-GIS kukuthembeka okuphezulu kunye nokhuseleko olunikezelayo. Inxalenye eqhubayo yesekethe ephambili ivalwe kwigesi ye-SF6, kwaye i-high-voltage live conductor ayichaphazeli kwizinto zangaphandle zokusingqongileyo. Oku kuvumela izixhobo ukuba zisebenze ngokukhuselekileyo ixesha elide ngaphandle kokubeka engozini ukuthembeka. Ngoko ke, umngcipheko wokutshatyalaliswa kombane okanye umlilo uyancipha kakhulu, uqinisekisa ukhuseleko lomnatha wokusabalalisa amandla.
Uyilo oluzimeleyo lwemodyuli:
Indlela yoyilo oluyimodyuli yeGIS yongeza lula ukufakela nokugcinwa. Ibhokisi yomoya yenziwe ngepleyiti ye-aluminium echanekileyo kwaye kulula ukuyifaka kunye nokuqhaqha. Ukongeza, iswitshi yokwahlula yamkele isikhululo esine-linear transmission mechanism, esinciphisa i-clutter kwaye siphucule amandla olawulo ngokubanzi. Ukuqaliswa kwemodyuli yolawulo ephantse ibe ngamanqaku e-PLC angama-100 yenza ukuba umhlaba usebenze ngokufanelekileyo kunye nokutshintsha okukodwa, zonke zisebenza kude. Uyilo lwemodyuli lukwasusa imiba efana nonikezelo lwamandla olungazinzanga kunye nokumelana nokunxibelelana okugqithisileyo, ukusombulula iingxaki ezinokuthi zibe khona zokuphazamiseka kwinkqubo yokuhanjiswa kwamandla.
Ulawulo olubalaseleyo lokukhupha:
Imveliso yokutshintsha indawo yokuqhawula ihlala ijongana nemiba yokukhutshelwa ngokuyinxenye, ekhokelela ekungazinzini kunye nokongamela. Ukoyisa le mingeni, iminqwazi yokulinganisa ekhuselekileyo ifakwe kumphandle wendawo nganye yoqhagamshelwano. Esi sisombululo sitsha sisombulula ngokufanelekileyo ingxaki yokukhupha inxalenye kwaye siqinisekisa inethiwekhi yokuhambisa amandla egudileyo kwaye engaphazamiseki.
Usetyenziso olufanelekileyo kunye nolungiselelo:
I-GIS iyilwe njengeyunithi ezimeleyo ekwaziyo ukuhlangabezana nazo zonke iimfuno eziphambili zeekhebhuli. Iyunithi nganye ihanjiswa kwisiza kwifom edibeneyo, inciphisa kakhulu umjikelo wofakelo kwisayithi. Oku akugcini nje ukugcina ixesha kodwa kuphucula ukuthembeka ngokubanzi kwenkqubo yokusabalalisa. Ukusetyenziswa okufanelekileyo kunye nokuthunyelwa kwezisombululo ze-GIS zenza ukuba zilungelelanise kakhulu kwiimfuno ezahlukeneyo zokuhambisa amandla.
Ukuqukumbela, inkqubo ye-35kv 1250A GIS ineenzuzo ezininzi, ezifana noyilo oludibeneyo, ukuthembeka okuphezulu kunye nokhuseleko oluphuculweyo. Ngoyilo lwayo oluzimeleyo lwemodyuli kunye nolawulo olusebenzayo lokukhupha, izisombululo ze-GIS zibonelela ngendlela elula yokuhanjiswa kwamandla. Ukongeza, isicelo esilula kunye nokubekwa kunceda ukunciphisa ixesha lomjikelo wofakelo kunye nokuqinisekisa ukuthembeka kwenkqubo ephuculweyo. Njengoko imfuno yokusasazwa kwamandla okusebenzayo iqhubeka ikhula, i-GIS ngokungathandabuzekiyo sisisombululo esifanelekileyo sokuhlangabezana neemfuno eziguqukayo zoluntu lwanamhlanje.
