電壓經(jīng)升壓變壓器升壓后，線路傳輸?shù)碾娏鳒p小,可以減少線路損耗，提高送電經(jīng)濟(jì)性，達(dá)到遠(yuǎn)距離送電的目的，而降壓則能滿足各級(jí)使用電壓的用戶需要。對(duì)于渦流的解釋是當(dāng)交流電流通過(guò)導(dǎo)線時(shí)，在導(dǎo)線周圍會(huì)產(chǎn)生交變的磁場(chǎng)。交變磁場(chǎng)中的整塊導(dǎo)體的內(nèi)部會(huì)產(chǎn)生感應(yīng)電流，由于這種感應(yīng)電流在整塊導(dǎo)體內(nèi)部自成閉合回路，很像水的旋渦，所以稱作渦流。渦流不但會(huì)白白損耗電能，使用電設(shè)備效率降低，而且會(huì)造成用電器（如變壓器鐵芯）發(fā)熱，嚴(yán)重時(shí)將影響設(shè)備正常運(yùn)行。</p><div
