江蘇華辰發明了一種干式(shi)變(bian)壓器低壓箔(bo)式(shi)線(xian)圈引(yin)線(xian)結構(gou)及(ji)引(yin)線(xian)繞制工藝，涉及(ji)變(bian)壓器領域。發明采(cai)用雙層箔(bo)分流疊繞結構(gou)纏(chan)繞，每(mei)層銅箔(bo)采(cai)用單獨的引(yin)出結構(gou)，使(shi)得低壓線(xian)圈額定電流平分到每(mei)組引(yin)線(xian)銅排(pai)上(shang)，有效(xiao)避免了電流過大(da)時導致的銅排(pai)適用度小的問題，同時也有效(xiao)縮減了現場使(shi)用場地。
