</p> <p> 市電供電時，交流電經(jīng)端口1流入變壓器，在穩(wěn)壓電路的控制下選擇合適的變壓器抽頭接入，同時在端口2的雙向變換器的作用下借助蓄電池的能量轉(zhuǎn)換共同調(diào)節(jié)端口3上的輸出電壓，以此來達到比較好的穩(wěn)壓效果；市電掉電時，蓄電池通過雙向變換器經(jīng)端口2給變壓器供電，維持端口3上的交流輸出。銅仁科華ups不間斷電源廠商UPS用來作為儲存電能的裝置，使其在市電失電時，可以將直流電逆變后，為負載提供不間斷電源。</p><div

STS(靜態(tài)開關(guān)),LBS(同步器)及雙總線作用是什么？ </p> <p> STS的作用是將兩路輸入交流電進行切換。 </p> <p> LBS的作用是將兩組UPS同步，目的是為了使STS的切換時間為零。 </p> <p> 雙總線的作用是為了給用電設(shè)備提供冗余的電源。 </p> <p> EPS和在線式UPS的主要區(qū)別是什么？兩者的主要用途是什么？ </p> <p> 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> <p> 不同之處：EPS由于帶的負載不同，比如照明和啟動水泵等，功率需要做的很大，在啟動水泵時可以將逆變器做成變頻器；而后備式UPS由于主要的對象是PC機之類的IT設(shè)備，所以容量很少有超過3KVA的。都是由UPS電源的逆變器對負載供電，這樣就避免了所有由市電電網(wǎng)電壓波動及干擾而帶來的影響。</p><div style="width:100%;text-align:
