由智(zhi)光電(dian)氣承(cheng)建的秦(qin)皇島港(gang)高壓(ya)(ya)船舶岸(an)(an)電(dian)系統在秦(qin)皇島709泊位成(cheng)(cheng)功為76000噸的“神華(hua)801”輪順利接電(dian)，實現了(le)一次(ci)性連船成(cheng)(cheng)功，采(cai)用(yong)岸(an)(an)上高壓(ya)(ya)電(dian)源(yuan)直(zhi)接供電(dian)，經大功率電(dian)力電(dian)子技術進(jin)行變換(huan)之后可直(zhi)接實現異(yi)頻雙高電(dian)壓(ya)(ya)（6.6kV及11kV）輸出，可適應不同船舶電(dian)壓(ya)(ya)等級(ji)的需(xu)要，中間回路(lu)無需(xu)采(cai)用(yong)降壓(ya)(ya)及升壓(ya)(ya)變壓(ya)(ya)器來(lai)實現電(dian)壓(ya)(ya)變換(huan)，轉換(huan)效率高。
