</p> <p> EPS電源又稱EPS、消防應急電源，全稱Emergency Power Supply（緊急電力供給），國家新標準為GB17945-2010《消防應急照明與疏散指示系統(tǒng)》。 </p> <p> <br /> </p> <p> 簡介編輯 </p> <p> 是當今重要建筑物中為了電力保障和消防安全而采用的一種應急電源。它主要由輸入輸出單元、充電模塊、電池組、逆變器、監(jiān)控器、輸出切換裝置等部分組成。廣泛應用于節(jié)能供電、大樓照明、道路交通照明、隧道照明、電力、工礦企業(yè)、消防電梯等。 </p> 原理編輯其原理為：在市電正常時，由市電經(jīng)過輸出切換裝置給重要負荷供電，同時充電器為蓄電池進行充電或浮充；當市電斷電后或電壓超出供電范圍，控制器啟動逆變器，同時輸出切換裝置將市電供電狀態(tài)立即切換到逆變器供電，為負荷設備提供應急供電；當市電恢復時，應急電源將恢復為市電供電。EPS是以解決應急照明、***照明、消防設施等一級負荷供電設備為主要目標，提供一種符合消防規(guī)范的具有**回路的應急供電系統(tǒng)，該系統(tǒng)能夠在應急狀態(tài)下提供緊急供電，用來解決照明用電或只有一路市電缺少第二路電源，或代替發(fā)電機組構成第二電源，或做為需要第三電源的場合使用。
