由智光電(dian)(dian)氣(qi)承建的(de)秦皇島港高(gao)壓(ya)(ya)(ya)船舶岸電(dian)(dian)系(xi)統在秦皇島709泊位成功(gong)為76000噸的(de)“神華(hua)801”輪順利接電(dian)(dian)，實現(xian)了一次性連船成功(gong)，采用岸上高(gao)壓(ya)(ya)(ya)電(dian)(dian)源直接供電(dian)(dian)，經(jing)大功(gong)率(lv)電(dian)(dian)力電(dian)(dian)子技術進行變(bian)換之后可(ke)直接實現(xian)異頻雙高(gao)電(dian)(dian)壓(ya)(ya)(ya)（6.6kV及(ji)11kV）輸出，可(ke)適(shi)應不同船舶電(dian)(dian)壓(ya)(ya)(ya)等級的(de)需要，中間回(hui)路無需采用降壓(ya)(ya)(ya)及(ji)升壓(ya)(ya)(ya)變(bian)壓(ya)(ya)(ya)器來(lai)實現(xian)電(dian)(dian)壓(ya)(ya)(ya)變(bian)換，轉換效率(lv)高(gao)。
