Ma Cable High Voltage vs. Low Voltage Cables: Kusiyana Kwakukulu Kufotokozedwa

Pankhani ya uinjiniya wamagetsi, kusankha zingwe zamphamvu kwambiri komanso zotsika kwambiri ndikofunikira kuti zitsimikizire kufalitsa mphamvu zotetezeka, zogwira mtima komanso zodalirika. Kumvetsetsa kusiyana kwakukulu pakati pa mitundu iwiri ya zingwezi kungathandize mainjiniya, akatswiri amagetsi, ndi oyang'anira polojekiti kupanga zisankho zodziwikiratu pazosankha zawo zenizeni.

Tanthauzo ndi mtundu wamagetsi

Zingwe zamphamvu kwambiriadapangidwa kuti azinyamula ma voltages omwe ali pamwamba pa 1,000 volts (1 kV). Zingwezi ndizofunikira potumiza magetsi pamtunda wautali, monga kuchokera ku mafakitale opangira magetsi kupita ku malo ang'onoang'ono kapena pakati pa masiteshoni ndi ma network ogawa. Zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo zingwe zamagetsi zam'mwamba ndi njira zotumizira mobisa.

Koma zingwe zotsika mphamvu, zimagwira ntchito pamagetsi ochepera 1,000 volts. Amagwiritsidwa ntchito kawirikawiri pakuwunikira, kugawa mphamvu ndi machitidwe olamulira m'malo okhala, malonda ndi mafakitale. Mwachitsanzo, zingwe zomwe zimagwiritsidwa ntchito pamawaya apanyumba, mabwalo owunikira ndi makina ang'onoang'ono.

Zomanga ndi zipangizo

Mapangidwe a zingwe zamphamvu kwambiri ndizovuta kwambiri kuposa zingwe zotsika kwambiri. Zingwe zamphamvu kwambiri nthawi zambiri zimakhala ndi zigawo zingapo, kuphatikiza ma conductor, zoteteza, zishango ndi ma sheath akunja. Zida zotetezera ndizofunikira kuti tipewe kutayikira ndikuonetsetsa chitetezo. Zida zomwe zimagwiritsidwa ntchito nthawi zambiri pazingwe zothamanga kwambiri zimaphatikizapo polyethylene (XLPE) yolumikizirana ndi ethylene-propylene rabara (EPR).

Zingwe zamagetsi zotsika nthawi zambiri zimakhala zosavuta kupanga, ngakhale zimafunikirabe zida zapamwamba. Nthawi zambiri amatsekeredwa pogwiritsa ntchito PVC (polyvinyl chloride) kapena mphira, yomwe imakhala yokwanira kutsika kwamagetsi. Zipangizo za conductor zimatha kusiyana, koma mkuwa ndi aluminiyamu ndizo zosankha zofala kwambiri pakugwiritsa ntchito magetsi apamwamba komanso otsika.

Magwiridwe ndi chitetezo

Zingwe zamphamvu kwambiriamapangidwa kuti athe kupirira mikhalidwe yovuta kwambiri, kuphatikiza kutentha kwambiri, kupsinjika kwamakina ndi zinthu zachilengedwe. Nthawi zambiri amayesedwa mphamvu ya dielectric, yomwe imayesa kuthekera kwa chingwe kukana kuwonongeka kwa magetsi. Izi ndizofunikira kuti zitsimikizire chitetezo ndi kudalirika kwa njira yotumizira mphamvu.

Mosiyana ndi izi, zingwe zotsika mphamvu zimapangidwira malo osafunikira kwambiri. Ngakhale akufunikabe kukwaniritsa miyezo yachitetezo, zofunikira zogwirira ntchito sizili zolimba ngati zingwe zamphamvu kwambiri. Komabe, zingwe zamagetsi zotsika ziyenera kutsatirabe ma code amagetsi am'deralo kuti zitsimikizire kuti zikugwira ntchito bwino.

Kugwiritsa ntchito

Kugwiritsa ntchito zingwe zamphamvu kwambiri komanso zingwe zotsika kwambiri ndizosiyana kwambiri. Zingwe zamagetsi zamagetsi zimagwiritsidwa ntchito makamaka popanga magetsi, kutumiza ndi kugawa. Ndiwofunika kwambiri pakulumikiza magwero a mphamvu zongowonjezwdwanso monga mphepo ndi minda ya solar ku gridi.

Komabe, zingwe zotsika mphamvu zimakhala paliponse pamoyo watsiku ndi tsiku. Amagwiritsidwa ntchito mu mawaya okhalamo, nyumba zamalonda ndi malo ogulitsa mafakitale kuti aziwunikira, kutentha ndi mphamvu zamagetsi zosiyanasiyana. Kusinthasintha kwawo kumawapangitsa kukhala oyenerera ntchito zosiyanasiyana, kuchokera kumayendedwe osavuta apanyumba kupita ku machitidwe ovuta owongolera pazopanga zopanga.

Pomaliza

Mwachidule, kusankha kwa zingwe zamphamvu kwambiri komanso zotsika kwambiri zimadalira zofunikira zenizeni zamagetsi ogwirizana nawo. Zingwe zamphamvu kwambiri ndizofunikira kuti magetsi aziyenda bwino pamtunda wautali, pomwe zingwe zotsika kwambiri ndizofunikira pakugwiritsa ntchito magetsi tsiku lililonse. Kumvetsetsa kusiyana kwakukulu pakumanga, ntchito, ndi kugwiritsa ntchito kungathandize akatswiri kupanga zisankho zoyenera kuti atsimikizire chitetezo ndi kudalirika kwa machitidwe awo amagetsi. Kaya mukupanga gridi yatsopano yamagetsi kapena mawaya apanyumba, kudziwa nthawi yogwiritsira ntchito zingwe zothamanga kwambiri komanso zotsika kwambiri ndikofunikira kuti muchite bwino.
