YINTONI UMAHLUKO PHAKATHI KWECABLE YAMANDLA NECABLE EPHEZULU?

1. Iintambo ezahlukeneyo

1. Intambo yamandla

Iintambo zombane ziintambo ezisetyenziselwa ukuhambisa nokusasaza amandla ombane. Iintambo zombane zihlala zisetyenziswa kwiigridi zombane ezingaphantsi komhlaba ezidolophini, kwiintambo zokukhupha izitishi zombane, kubonelelo lwangaphakathi lwamandla kumashishini emizi-mveliso nakwimigodi, nakwiintambo zothumelo lwamanzi ngaphantsi kwamanzi eziwela imilambo nolwandle.

2. Intambo engaphambili

Iintambo zomoya (iintambo ezigqunywe ngaphezulu ezibizwa ngegama elipheleleyo) zii-conductors eziphezulu ezixhotyiswe ngeeleya zokukhusela kunye neesheya zokukhusela. Zenziwa ngenkqubo yemveliso efana neyeentambo ezidityanisiweyo. Indlela.

Ezimbini, udidi olwahlukileyo

1. Intambo yamandla

Ngokwenqanaba le-voltage, ingahlulwahlulwa ibe ziintambo zamandla ze-voltage eziphakathi neziphantsi (35kV nangaphantsi), iintambo ze-voltage eziphezulu (ngaphezulu kwe-110kV), iintambo ze-voltage eziphezulu kakhulu (275-800kV) kunye neentambo ze-UHV (1000kV nangaphezulu). Ukongeza, ingahlulwa ibe ziintambo ze-AC kunye neentambo ze-DC ngokwenkqubo yangoku.

2. Intambo engaphambili

Iintambo ezisetyenziswa ngaphezulu zi-single-core, ezinokwahlulwa zibe yi-hard aluminium wire structure, hard-drawn copper wire structure, aluminium alloy wire structure, steel core okanye aluminium alloy core support structure kunye ne-self-supported three-core textured structures ngokwezakhiwo zazo ezahlukeneyo (I-wire core inokuba yi-aluminium eqinileyo okanye i-hard copper wire) njalo njalo.

Iimpawu ezintathu, ezahlukeneyo

1. Intambo yamandla

1) Indawo encinci. Ngokuqhelekileyo igqunywe emhlabeni okanye ibekwe ngaphakathi, kwimisele nakwiitonela, umgama wobushushu phakathi kwemigca mncinci, akukho zibonda kunye neenqaba ezifunekayo, kwaye ithatha umhlaba omncinci kwaye ngokusisiseko ayithathi ndawo emhlabeni.

2) Ukuthembeka okuphezulu. Ayichaphazeleki kakhulu ziimeko zemozulu kunye nokusingqongileyo okungqongileyo, kwaye ukusebenza kothumelo kuzinzile.

2. Intambo engaphambili

1) Ukuthembeka okuphezulu kombane

Ukusetyenziswa kweentambo ezisetyenziswa ngaphezulu kunokunciphisa kakhulu zonke iintlobo zeempazamo ze-short-circuit (ingakumbi iimpazamo eziqhelekileyo ze-flashover zeentambo ezingenanto ezisetyenziswa ngaphezulu), kwaye izinga lokungaphumeleli liphantsi ngokuphindwe ka-4-6 kuneentambo ezingenanto ezisetyenziswa ngaphezulu.

Intambo ye-overhead yasekhaya yafakwa kwisilingo eShanghai ngo-1988. Intambo ye-overhead yovavanyo yayihamba kwi-boulevard exineneyo yeHuaihai Road. Emva kovavanyo lwexesha le-typhoon eShanghai kunye nobushushu obuphezulu ehlotyeni, yayisebenza kakuhle, kwaye izinga layo lokungaphumeleli kombane lancitshiswa kakhulu xa kuthelekiswa nentambo yokuqala engenanto ye-overhead. Iintambo zomoya aziyi kuvelisa imithi yamanzi ngexesha lokusetyenziswa, kwaye umgangatho wobushushu beentambo awuyi kwehla kakhulu emva kweminyaka yokusebenza.

2) Ukhuseleko olufanelekileyo lombane

Ukusetyenziswa kweentambo eziphezulu kunciphisa kakhulu iingozi zombane ezibangelwa kukuqhawuka kwabantu.
