style="text-indent:25px">UPS(不間斷電源)的工作原理：后備式UPS電源在市電正常供電時(shí)，市電通過交流旁路通道經(jīng)轉(zhuǎn)換開關(guān)直接向負(fù)載提供電源，UPS電源內(nèi)的逆變器處于停止工作狀態(tài)，這時(shí)的UPS電源實(shí)質(zhì)上相當(dāng)于一臺性能單一的市電穩(wěn)壓器。它除了對市電電壓的幅度波動有所改善外，對電壓的頻率不穩(wěn)、波形畸變以及從電網(wǎng)侵入的*等不良影響基本上沒有任何改善。只有當(dāng)市電供電中斷或低于170伏時(shí)，蓄電池才立刻對逆變器供電，向負(fù)載提供穩(wěn)壓、穩(wěn)頻的方波交流電源。正常工作一段時(shí)間，這就需要啟用備用電源來維持這段時(shí)間監(jiān)控系統(tǒng)的正常工作。備用電源有雙路或多路供電、蓄電池組供電、發(fā)電機(jī)供電、UPS供電等等。但通常采用UPS不間斷電源作為安防監(jiān)控系統(tǒng)備用電源。</p><p style="text-indent:25px">如何配置安防監(jiān)控系統(tǒng)中UPS電源：UPS是伴隨計(jì)算機(jī)的誕生而出現(xiàn)后備電源。在安防監(jiān)控系統(tǒng)中越來越多應(yīng)用計(jì)算機(jī)技術(shù)，因此對電力供電質(zhì)量提出越來越高的要求。UPS不但可較全改善供電質(zhì)量，對整個(gè)系統(tǒng)乃至網(wǎng)絡(luò)數(shù)據(jù)較全保護(hù)，還可保證市電斷電和被人為破壞的特殊情況下，繼續(xù)正常工作運(yùn)轉(zhuǎn)。由于安防監(jiān)控系統(tǒng)對供電要求較高，所以一般會選擇在線式(正弦波，市電要求)UPS電源。給安防監(jiān)控系統(tǒng)配備UPS電源時(shí)，首先應(yīng)估算整個(gè)系統(tǒng)設(shè)備的用電功率，安全系數(shù)一般取1.2-1.5為宜，為供電系統(tǒng)留有充分的冗余量。其次根據(jù)系統(tǒng)要求延時(shí)供電時(shí)間，計(jì)算配置電池組。較后，還應(yīng)注意使用環(huán)境，防潮通風(fēng)，注重降溫，延長平均無故障工作時(shí)間，提高系統(tǒng)的可靠性。UPS電源應(yīng)設(shè)置在監(jiān)控室，實(shí)行統(tǒng)一管理。當(dāng)市電不正常時(shí)能及時(shí)為系統(tǒng)設(shè)備提供不間斷電力供應(yīng)，確保系統(tǒng)工作正常。普通電源對于電源的適應(yīng)能力相對較弱，適合那些電源電壓穩(wěn)定的地方。</p><div
