Kodi Chingwe Chotsitsa Utumiki Wapamwamba N'chiyani?

Zingwe zogwetsera magetsi pamwamba ndi zingwe zomwe zimapereka zingwe zamagetsi zakunja. Ndi njira yatsopano yotumizira mphamvu pakati pa ma conductors a pamwamba ndi zingwe zapansi panthaka, zomwe zinayamba kafukufuku ndi chitukuko kumayambiriro kwa zaka za m'ma 1960.

Zingwe zotulutsira zinthu pamwamba zimapangidwa ndi chotchingira kutentha ndi chotchingira choteteza, mofanana ndi njira yopangira zingwe zolumikizidwa. Ngakhale kuti zimakhala zosavuta kusokonezedwa ndi zinthu zakunja ndipo sizikongola, zimagwiritsidwa ntchito kwambiri m'malo omwe zimakhala zovuta kuyika zingwe zapansi panthaka chifukwa cha kudalirika kwawo pamagetsi, kukhazikika, komanso kukonza kosavuta.

Kodi timasankha bwanji chingwe chotsitsa ntchito cha pamwamba?

Mitundu itatu ya zingwe zogwetsera zitsulo za aluminiyamu ndi zingwe zogwetsera zitsulo za duplex service drop, zingwe zogwetsera zitsulo za triplex service drop, ndi zingwe zogwetsera zitsulo za quadruplex service drop. Zimasiyana malinga ndi kuchuluka kwa ma conductor ndi ntchito zofala. Tiyeni tikambirane mwachidule za ntchito ya chilichonse mwa izi.

Zingwe zodulira ma duplex service drop zomwe zili ndi ma conductor awiri zimagwiritsidwa ntchito mumagetsi amtundu umodzi pakugwiritsa ntchito ma volt 120. Kawirikawiri zimagwiritsidwa ntchito mumakina owunikira panja, kuphatikizapo magetsi a m'misewu. Komanso, nthawi zambiri zimagwiritsidwa ntchito mu bizinesi yomanga kuti zigwiritsidwe ntchito kwakanthawi. Zosangalatsa - Kukula kwa zingwe zodulira ma duplex aku America kumatchedwa mayina a mitundu ya agalu, kuphatikiza agalu a setter, shepherd, ndi chow.

Zingwe zogwetsera ntchito za Triplex zokhala ndi ma conductor atatu zimagwiritsidwa ntchito kunyamula magetsi kuchokera ku zingwe zamagetsi kupita kwa makasitomala, makamaka, kupita kwa oyang'anira nyengo. Apanso, zingwe zogwetsera ntchito za triplex zaku America zili ndi mbiri yosangalatsa. Dzina lawo limatchedwa kuchokera ku mitundu ya nyama zam'madzi, monga nkhono, nkhanu, ndi nkhanu. Mayina a zingwe ndi awa: Paludina, Valuta, ndi Minex.

Zingwe zogwetsa magetsi za Quadruplex zokhala ndi ma conductor anayi zimapangidwa kuti zipereke mawaya amagetsi a magawo atatu. Zimalumikiza ma transformer amagetsi okhala ndi ndodo, omwe amapezeka kwambiri kumidzi, ndi atsogoleri a ogwiritsa ntchito. Zingwe za Quadruplex zomwe zimakwaniritsa zofunikira za NEC zimatchedwa mayina a mitundu ya akavalo, monga Gelding ndi Appaloosa.

Kupanga Zingwe Zotayira Aluminiyamu

Ngakhale kuti mawaya onse amagetsi oyendetsera magetsi amasiyana ntchito komanso kuchuluka kwa mawayawa, ali ndi kapangidwe kofanana. Mawaya amagetsi awa amapangidwa ndi aluminiyamu 1350-H19,6201-T81 kapena ACSR.

Ali ndi polyethylene XLPE yolumikizidwa ndi cross-linked yomwe imapereka chitetezo chachikulu ku zoopsa zakunja. Makamaka, imalimbana bwino ndi chinyezi, nyengo, komanso zotsatira za mankhwala osiyanasiyana. Kutentha kwa zingwe za aluminiyamu pamwamba pa chingwe chokhala ndi XLPE insulation ndi madigiri 90 Celsius. Nthawi zambiri, polyethylene insulation ingagwiritsidwe ntchito m'malo mwa XLPE insulation. Pankhaniyi, kutentha kwa ntchito kumachepetsedwa kufika madigiri 75, zomwe ndi chinthu choyenera kukumbukira mukaganizira za polojekiti yanu yamagetsi. Voltage rating ya mawaya onse amagetsi pamwamba pa chingwe ndi ma volts 600.

Zingwe zonse zotayira zitsulo za aluminiyamu zimakhala ndi waya wolumikizira magetsi kapena waya wolumikizira magetsi. Cholinga cha wolumikizira magetsi ndikupanga njira yolumikizira magetsi kuti magetsi azitha kutuluka ndikupewa ngozi, zomwe ndizofunikira kwambiri pakupanga mawaya akunja. Mawaya a olumikizira magetsi amatha kupangidwa ndi zinthu zosiyanasiyana, monga AAC, ACSR, kapena mtundu wina wa aluminiyamu.

Ngati mukufuna kufunsidwa za ma service drop conductors, chonde titumizireni uthenga.
