Ma transformer opangidwa ndi Pad ndi mabokosi achitsulo obiriwira omwe ali mdera lanu omwe amasintha magetsi amphamvu kukhala magetsi otsika oyenera nyumba ndi mabizinesi. Zinthu zofunika izi zimatsimikizira kuti muli ndi magetsi oyenera.

Kodi Transformer Yokwera Pamwamba Ndi Chiyani?

Transformer yokhala ndi ma pad ndi chipangizo chofunikira chamagetsi chomwe chimayikidwa pansi, nthawi zambiri chimayikidwa pa konkireti. Chomwe chimapezeka kwambiri m'madera okhala anthu ndi m'malo amalonda, zitsulo zobiriwira izi zimathandiza kuchepetsa magetsi amphamvu kuchokera ku zingwe zamagetsi kupita ku magetsi otsika oyenera kugwiritsidwa ntchito m'nyumba ndi m'malonda.

Ma transformer okhala ndi ma pad-mounted amakhala otetezeka komanso okongola kwambiri poyerekeza ndi mitundu yomangidwira ndi ndodo. Chotchingachi chimateteza chipangizocho ku nyengo ndipo chimachepetsa chiopsezo cha kusokonezedwa kapena kukhudzana mwangozi ndi zinthu zamoyo.

Momwe Transformer Yokwera Pamwamba Imagwirira Ntchito

Ma transformer okhazikika pa Pad amasintha magetsi amphamvu kwambiri kuchokera ku mizere yoyambira yogawa magetsi kukhala ma voltage otsika oyenera kugwiritsidwa ntchito m'nyumba ndi m'mabizinesi. Ma transformer awa amatsitsa ma voltage kuyambira 4,160 mpaka 34,500 volts kupita ku milingo yosavuta kulamulira, monga ma volts 120/240 m'nyumba ndi ma volts 480 m'mabizinesi.

Pakati pa transformer yokhala ndi ma pad pali transformer yokha, yomwe ili ndi zigawo ziwiri zazikulu: ma windings oyambira ndi achiwiri. Ma windings oyambira amalandira mphamvu yamagetsi yapamwamba, nthawi zambiri kuyambira ma volts 4,160 mpaka 34,500. Ma windings awa amalumikizidwa ndi ma coils amkuwa kapena aluminiyamu ozunguliridwa mozungulira pakati pa chitsulo. Mphamvu ya maginito yomwe imapangidwa ndi mphamvu yamagetsi yomwe ikuyenda kudzera mu ma windings oyambilira imayambitsa mphamvu yamagetsi mu ma windings oyambilira.

Kuzungulira kwachiwiri, komwe kumapangidwanso ndi ma coil amkuwa kapena aluminiyamu, kumapangidwa ndi kuchuluka kwa ma turn kuti apange voteji yotulutsa yomwe ikufunika, nthawi zambiri ma volts 120/240 ogwiritsidwa ntchito m'nyumba kapena ma volts 277/480 ogwiritsidwa ntchito pamalonda. Chiŵerengero cha ma turn pakati pa ma windings oyambira ndi achiwiri chimatsimikizira chiŵerengero cha kusintha kwa voteji, motsatira mfundo ya induction yamagetsi.

Zigawo za Transformer Yokwera pa Pad
