style="text-indent:25px">工作原理：在線式ups電子結(jié)構(gòu)圖當(dāng)在線式UPS在電網(wǎng)供電正常時(shí)，電網(wǎng)輸入的電壓一路經(jīng)過噪聲濾波器去除電網(wǎng)中的高頻干擾，以得到純凈的交流電，然后分別進(jìn)入充電器對(duì)蓄電池充電，另一路進(jìn)入整流器進(jìn)行整流和濾波，并將交流電轉(zhuǎn)換為平滑直流電供給逆變器，而逆變器又將直流電轉(zhuǎn)換成220V，50Hz的交流電供負(fù)載使用。當(dāng)發(fā)生市電中斷時(shí)，交流電的輸入已被切斷，整流器不再工作，此時(shí)蓄電池放電把能量輸送到逆變器，再由逆變器把直流電變成交流電，天津小型UPS不間斷電源廠家電話，供負(fù)載使用。因此，對(duì)負(fù)載來說，天津小型UPS不間斷電源廠家電話，天津小型UPS不間斷電源廠家電話，盡管市電已不復(fù)存在，但此時(shí)負(fù)載并未因市電中斷而停運(yùn)，仍可以正常運(yùn)行。UPS不間斷電源當(dāng)一部分負(fù)載接通或斷開時(shí)，都會(huì)使負(fù)載產(chǎn)生階躍變化。天津小型UPS不間斷電源廠家電話</p><div

style="text-indent:25px">從專業(yè)的角度說，看一臺(tái)UPS的好與不好，較客觀和較可靠的方法就是用測(cè)試指標(biāo)去衡量。就拿影響電網(wǎng)供電質(zhì)量的輸入功率因數(shù)來說，尤其是在大容量范圍時(shí)，一般傳統(tǒng)雙變換型UPS的標(biāo)配功率因數(shù)大都在0.8左右，這就造成了約有30%的諧波電流對(duì)電網(wǎng)的*，其結(jié)果是使該電網(wǎng)上的變壓器、電纜、保險(xiǎn)絲和開關(guān)等設(shè)備發(fā)熱、疲勞。若要改變這種狀況就必須在前面加諧波濾波器或改6脈沖整流為12脈沖整流，但這又會(huì)帶來兩個(gè)副作用：一個(gè)是增加包括UPS在內(nèi)的電源保護(hù)設(shè)備的成本和體積重量，另一方面增加了UPS的損耗，從而降低了可靠性。UPS不間斷電源設(shè)備通常對(duì)電壓過大和電壓太低都提供有力的保護(hù)。</p><div
