發(fā)展UPS技術(shù)的主要目的是提高UPS對輸出端負載的動態(tài)響應(yīng)越來越快又好。顯然，采用先進的高頻技術(shù)，動態(tài)響應(yīng)速度很快，效果比較好。 </p> <p> 傳統(tǒng)工頻機帶輸出隔離變壓器是否可以增加帶載能力和降低零地電壓？ </p> <p> 工頻機的輸出隔離變壓器嚴格講是它逆變部分不可或缺的組件，沒有全隔離效果，因為旁路無隔離，零線無隔離。 </p> <p> UPS上有防雷嗎？ </p> <p> UPS可以選配輸入C級防雷，它有兩種方式： </p> <p> 以保護負載為優(yōu)先的防雷； </p> <p> 以保護供電為優(yōu)先的防雷，但是作用不大。因為UPS裝了防雷充其量只能使配電柜中省一級防雷，但是配電當中還是不能省略防雷裝置。 </p><p>持續(xù)低電壓（brownout）：</p><p>指市電電壓有效值低于額定值，并且持續(xù)較長時間。其產(chǎn)生原因包括：大型設(shè)備啟動和應(yīng)用、主電力線切換、啟動大型電動機、線路過載。</p><p>市電中斷（powerfai1）：</p><p>指市電中斷并且持續(xù)至少兩個周期到數(shù)小時的情況。其產(chǎn)生原因有：線路上的斷路器跳閘、市電供應(yīng)中斷、電網(wǎng)故障。</p><p>對于電腦來說，顯示器及主機工作都需要正常的電力供應(yīng)。尤其是內(nèi)存，對電源的要求更高。它是一種依賴電能的存儲設(shè)備，需要不斷的刷新動作來保持存儲內(nèi)容。一旦斷電，所保存的內(nèi)容立即消失。如果非正常斷電，導(dǎo)致內(nèi)存中的信息來不及保存到硬盤等存儲設(shè)備上，就會造成信息因完全丟失或變得不完整而失去價值，從而浪費大量的工作精力、時間、甚至造成巨大的經(jīng)濟損失。與UPS相同之處：EPS是***的后備式UPS，它的工作原理和后備式UPS一樣。</p><div
