Emkhakheni wobunjiniyela bakagesi, ukukhethwa kwezintambo ezinamandla kagesi kanye nezamandla aphansi kubalulekile ukuze kuqinisekiswe ukudluliswa kwamandla okuphephile, okuphumelelayo nokuthembekile. Ukuqonda umehluko oyinhloko phakathi kwalezi zinhlobo ezimbili zamakhebuli kungasiza onjiniyela, abasebenza ngogesi, nabaphathi bephrojekthi benze izinqumo ezinolwazi ngezicelo zabo ezithile.
Incazelo kanye nobubanzi be-voltage
Izintambo zikagesi eziphezuluaklanyelwe ukuthwala amandla amanje kuma-voltage ngokuvamile angaphezu kuka-1,000 volts (1 kV). Lezi zintambo zibalulekile ekudluliseni ugesi ebangeni elide, njengokusuka ezizindeni zikagesi ukuya eziteshini ezincane noma phakathi kweziteshi ezincane namanethiwekhi okusabalalisa. Izinhlelo zokusebenza ezijwayelekile zihlanganisa izintambo zikagesi ezihamba phezulu kanye namasistimu okudlulisa angaphansi komhlaba.
Ngakolunye uhlangothi, amakhebuli ane-low-voltage asebenza kuma-voltage angaphansi kuka-1,000 volts. Zivame ukusetshenziselwa ukukhanyisa, ukusabalalisa amandla kanye nezinhlelo zokulawula ezindaweni zokuhlala, ezentengiselwano nezimboni. Isibonelo, izintambo ezisetshenziselwa izintambo zasendlini, izifunda zokukhanyisa nemishini emincane.
Ukwakha nezinto zokwakha
Ukwakheka kwezintambo ezinamandla kagesi ziyinkimbinkimbi kakhulu kunezintambo zamandla aphansi. Amakhebuli anamandla kagesi aphezulu ngokuvamile ahlanganisa izendlalelo eziningi, okuhlanganisa amakhondakta, ama-insulators, amahawu kanye namashethi angaphandle. Izinto zokufaka i-insulating zibalulekile ukuvimbela ukuvuza nokuqinisekisa ukuphepha. Izinto ezisetshenziswayo ezisetshenziswa kakhulu ezintanjeni zamandla kagesi aphezulu zifaka i-polyethylene (XLPE) exhumene ne-ethylene-propylene rubber (EPR).
Izintambo zikagesi eziphansi ngokuvamile zilula ekwakhiweni, nakuba zisadinga izinto zekhwalithi. Zivamise ukugqunywa kusetshenziswa i-PVC (i-polyvinyl chloride) noma irabha, eyanele ukulinganisa okuphansi kwamandla kagesi. Izinto ze-conductor zingahluka, kodwa ithusi ne-aluminium yizona zinketho ezivame kakhulu zokusetshenziswa kwamandla kagesi aphezulu naphansi.
Ukusebenza nokuphepha
Izintambo ezinamandla kagesizenzelwe ukumelana nezimo ezimbi kakhulu, okuhlanganisa izinga lokushisa eliphezulu, ukucindezeleka kwemishini kanye nezici zemvelo. Ngokuvamile zihlolelwa amandla e-dielectric, okulinganisa ikhono lekhebula lokumelana nokuphuka kukagesi. Lokhu kubalulekile ekuqinisekiseni ukuphepha nokwethembeka kohlelo lokudluliswa kwamandla.
Ngokuphambene, amakhebuli ane-low-voltage yakhelwe izindawo ezingadingeki kangako. Nakuba zisadinga ukuhlangabezana namazinga okuphepha, izimfuneko zokusebenza aziqinile njengezintambo ezinamandla kagesi. Kodwa-ke, amakhebuli kagesi aphansi kusafanele ahambisane namakhodi nemithetho kagesi endawo ukuze kuqinisekiswe ukusebenza okuphephile.
Isicelo
Ukufakwa kwezintambo ze-high-voltage kanye nezintambo ze-low-voltage zihluke kakhulu. Izintambo zikagesi eziphakeme zisetshenziswa kakhulu ekuphehleni ugesi, ekudluliselweni nasekusabalaliseni izinhlelo. Zibalulekile ekuxhumeni imithombo yamandla avuselelekayo njengamapulazi omoya kanye nelanga kugridi.
Nokho, izintambo ezinamandla kagesi aphansi zitholakala yonke indawo ekuphileni kwansuku zonke. Zisetshenziselwa izintambo zokuhlala, izakhiwo zezentengiselwano kanye nezindawo zezimboni ukukhanyisa, ukushisa kanye namandla ezinhlobonhlobo zemishini. Ukuguquguquka kwabo kubenza bafanelekele uhla olubanzi lwezinhlelo zokusebenza, kusukela kumasekhethi alula asekhaya kuya ezinhlelweni eziyinkimbinkimbi zokulawula ezitshalweni zokukhiqiza.
Ekuphetheni
Kafushane, ukukhethwa kwezintambo ze-high-voltage kanye ne-low-voltage kuncike ezidingweni ezithile zesistimu kagesi ehambisanayo. Izintambo ezinamandla kagesi zibalulekile ukuze kudluliswe ugesi ngendlela efanele uma uhamba amabanga amade, kuyilapho izintambo ezine-voltage ephansi zibalulekile ekusebenzeni kukagesi kwansuku zonke. Ukuqonda umehluko oyinhloko ekwakhiweni, ekusebenzeni, nasekusetshenzisweni kungasiza ochwepheshe benze izinqumo ezinolwazi ukuze baqinisekise ukuphepha nokuthembeka kwezinhlelo zabo zikagesi. Kungakhathaliseki ukuthi uklama igridi entsha kagesi noma izintambo zasekhaya, ukwazi ukuthi zisetshenziswa nini izintambo ezinamandla kagesi kanye nanamandla aphansi kubalulekile empumelelweni.
