沈(shen)陽干式變壓器是(shi)具有(you)高電(dian)(dian)(dian)(dian)(dian)氣(qi)強(qiang)度，能用電(dian)(dian)(dian)(dian)(dian)磁變換成電(dian)(dian)(dian)(dian)(dian)氣(qi)，是(shi)電(dian)(dian)(dian)(dian)(dian)力網中(zhong)必(bi)不可(ke)少的一種(zhong)設(she)備(bei)。簡單來說(shuo)就是(shi)把一種(zhong)交流電(dian)(dian)(dian)(dian)(dian)轉化(hua)成同頻率的另一種(zhong)交流電(dian)(dian)(dian)(dian)(dian)，從(cong)而保證電(dian)(dian)(dian)(dian)(dian)源的可(ke)靠性和靈活性。被廣(guang)泛用于局部照明等場(chang)所。

         因為干式變壓器具有抗短路能力強的優點，所以它的使用壽命更長。再加上它還具有節能低噪音，機身小的特點，使它可以大大減少后期的維修和養護。它采用國內的先進技術可以達到高能快捷的運行。同時它又具有安全、防火、無污染的優點，可以自行報警跳閘，所以干式變壓器常常被應用到防火、防爆等性能要求高的場所中。

         干式變壓器的(de)冷(leng)(leng)卻(que)方(fang)式可以(yi)分為自(zi)然(ran)和強(qiang)迫空氣冷(leng)(leng)卻(que)兩大(da)類。自(zi)然(ran)冷(leng)(leng)卻(que)可以(yi)連續運(yun)行(xing)，而強(qiang)迫冷(leng)(leng)卻(que)只適用于突發事故下負荷運(yun)行(xing)，但不(bu)適合(he)長(chang)期使用。
