Iintambo egqunywe phezuluiimveliso zothotho zenziwe ngobhedu olucinezelweyo kunye ne-aluminiyam (i-alloyi ye-aluminiyam) ii-conductors, umaleko okhuselayo wangaphakathi, izinto ezikhuselayo kwimozulu kunye nomaleko okhuselayo wangaphandle.Zizo zombini iimpawu zothumelo lwamandla eentambo zamandla kunye neempawu eziqinileyo zoomatshini zeentambo ezingaphezulu.Xa kuthelekiswa neengcingo ezingenanto, le mveliso ineempawu zokubeka isithuba esincinci, ukhuseleko oluphezulu kunye nokuthembeka, kunye nokumelana nokuguga okugqwesileyo kwe-atmospheric.
Ukusetyenziswa kweentambo ezigqunywe phezulu
Iimveliso zentambo ezigqunywe phezulu ziluluhlu olutsha lweemveliso zokuhambisa amandla ombane kwiintambo zothumelo ezingaphezulu.Zikhethwa kulwakhiwo lwegridi yombane kunye nokuguqulwa kweentambo zeprojekthi zothumelo lwe-10kV.Luluhlu lweemveliso ezifanelekileyo ukugcinwa komgca kunye nokhuseleko.Iimveliso zocingo oluthambileyo oluthambileyo lufanelekile kwi-transformer esezantsi.
Iimpawu zeentambo ezigqunywe phezulu
1. Ixabiso lombane: 0.6/1KV, 10KV;
2. Ukushisa kwexesha elide elivumelekileyo lokusebenza kwekhebula: 70 ° C kwi-polyvinyl chloride insulation kunye ne-90 ° C ye-cross-linked polyethylene insulation.
3. Ngexesha lesiphaluka esifutshane (esingadlulanga imizuzwana emi-5 ixesha elide), ubushushu obuninzi bekhebula: I-PVC insulation yi-160 ° C, i-high-density polyethylene insulation yi-150 ° C, kunye ne-cross-linked polyethylene insulation yi-250 ° C. ;
4. Ubushushu be-ambient ngexesha lokubeka intambo abuyi kuba ngaphantsi kwe -20℃
5. I-radius yokugoba evumelekileyo yeentambo: iintambo ezine-voltage elinganisiweyo ngaphantsi kwe-1KV: ukuba i-cable diameter yangaphandle (D) ingaphantsi kwe-25mm, akufanele ibe ngaphantsi kwe-4D, kwaye ukuba i-diameter yangaphandle yekhebula (D) yi-25mm nangaphezulu.
Kufuneka ingabi ngaphantsi kwe-6D;
Xa ugcina iintambo, akuvumelekanga ngokungqongqo ukuba udibane ne-acids, i-alkalis kunye ne-oyile yamaminerali, kwaye kufuneka zigcinwe zodwa kwezi zinto zitshabalalisayo;
Makungabikho iigesi eziyingozi ezonakalisa i-insulation kunye nentsimbi edlayo kwindawo yokugcina iintambo apho kugcinwa khona iintambo;
Zama ukunqanda ukugcina iintambo kwindawo evulekileyo.Amagubu ekhebhula awavumelekanga ukuba abekwe mcaba;
Intambo kufuneka ijikelezwe rhoqo ngexesha lokugcinwa (kanye kwiinyanga ezi-3 ehlotyeni, kwaye inokwandiswa ngokufanelekileyo kwamanye amaxesha onyaka).Xa uqengqeleka, jika umda wepleyiti yokugcina ujonge phantsi ukuze uthintele indawo esezantsi ukuba imanzi kwaye ibole.Xa ugcina, hlala ubeke ingqalelo ukuba intloko yekhebula ilungile;
Ixesha lokugcinwa kweentambo likhawulelwe kumhla wefektri yemveliso, ngokuqhelekileyo akufanele idlule iminyaka enye enesiqingatha kwaye ingabi ngaphezu kweminyaka emibini;
Akuvumelekanga ngokungqongqo ukulahla iintambo okanye iidramu zentambo eziqulethe iintambo ezivela kwiindawo eziphakamileyo ngexesha lokuthutha, ngakumbi kumaqondo okushisa aphantsi (ngokubanzi malunga ne-5 ° C nangaphantsi).Ukujula okanye ukuwisa iintambo kunokubangela ukuba isigqumathelo nesingxobo siqhekeke;
Xa uphakamisa iiphakheji, kunqatshelwe ngokungqongqo ukuphakamisa iitreyi ezininzi ngexesha elinye.Kwizithuthi, iinqanawa kunye nezinye izithuthi zokuthutha, iidramu zekhebula kufuneka zilungiswe ngeendlela ezifanelekileyo zokuthintela ukuba zingangqubani okanye zijike, kunye nokukhusela umonakalo womatshini kwiintambo.
