什么是防逆流裝置？

       什么(me)是(shi)“逆(ni)流(liu)(liu)”呢？在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)系(xi)(xi)統中，般都是(shi)由(you)配電(dian)(dian)(dian)(dian)(dian)(dian)(dian)變壓器向電(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)內各負載(zai)送電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，稱為正向電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)。安裝光(guang)(guang)伏(fu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)站后，當光(guang)(guang)伏(fu)系(xi)(xi)統功(gong)率大于(yu)(yu)本地(di)負載(zai)的功(gong)率時(shi)，消納(na)不完的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)要送入(ru)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)，由(you)于(yu)(yu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)方向和常規的相反，即稱為“逆(ni)流(liu)(liu)”。正常光(guang)(guang)伏(fu)發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)系(xi)(xi)統是(shi)將光(guang)(guang)伏(fu)組件直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)轉變成交(jiao)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)并入(ru)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)；帶防(fang)逆(ni)流(liu)(liu)的光(guang)(guang)伏(fu)系(xi)(xi)統是(shi)光(guang)(guang)伏(fu)發的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)僅供(gong)給就(jiu)地(di)負載(zai)使用(yong)，防(fang)止光(guang)(guang)伏(fu)系(xi)(xi)統發出(chu)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)送入(ru)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)網(wang)。
