對(duì)元器件耐高溫、濕熱、振動(dòng)、沖擊、防塵等無特殊要求。UPS不間斷電源機(jī)內(nèi)導(dǎo)線無阻燃或不燃要求。六、消防特性不同EPS應(yīng)急電源應(yīng)急電源裝置作為火災(zāi)時(shí)，為人員逃生提供照明的供電電源，在正常應(yīng)急放電完畢關(guān)機(jī)后，還可強(qiáng)制啟動(dòng)，直至電池完全放電為止，此時(shí)電池電壓下降，電流上升，溫升高，因此要求EPS應(yīng)急電源所配置的逆變器等元件必須能承受大電流的沖擊和高溫升的惡劣條件。逆變器必須有較大的電壓輸入范圍。EPS應(yīng)急電源的設(shè)計(jì)的出發(fā)點(diǎn)是為了保護(hù)人而不是保護(hù)設(shè)備的。UPS不間斷電源中配置的蓄電池在低于額定電壓關(guān)機(jī)后不可再啟動(dòng)，如額定電壓為12V的電池，當(dāng)電池電壓下降到10V左右時(shí)則自動(dòng)關(guān)機(jī)，以保護(hù)UPS電源設(shè)備。七、安全性能EPS消防應(yīng)急電源由于對(duì)消防設(shè)備特殊的人身安全要求，EPS應(yīng)急電源需配有隔離變壓器，以保證人身安全。UPS不間斷電源沒有配置隔離變壓器，如用于消防設(shè)備供電，存在觸電***。八、消防驗(yàn)收EPS消防應(yīng)急電源產(chǎn)品是國(guó)家強(qiáng)制認(rèn)證產(chǎn)品，必須取得生產(chǎn)許可認(rèn)證。UPS不間斷電源制造標(biāo)準(zhǔn)不是GB17945-2000的消防標(biāo)準(zhǔn)，沒有國(guó)家消防合格評(píng)定中心的認(rèn)證。不能通過消防驗(yàn)收。由此可見，eps消防應(yīng)急電源與ups不間斷電源有著明顯的區(qū)別。</p><div

因?yàn)樾陆暥容^高。晝夜溫差大，從而導(dǎo)致了風(fēng)扇中管變形，散熱風(fēng)扇不能正常工作也影響了UPS的運(yùn)轉(zhuǎn)。事實(shí)上，大多數(shù)散熱風(fēng)扇廠商都是使用通用PCB板，經(jīng)常生產(chǎn)大批量的產(chǎn)品做庫存，而相對(duì)于其他行業(yè)來說，UPS行業(yè)的應(yīng)用環(huán)境又比較惡劣，因此，普通的散熱風(fēng)扇根本就滿足不了行業(yè)的根本需求。另外，市場(chǎng)上的大多數(shù)散熱風(fēng)扇廠商都是屬于年輕企業(yè)，有的是經(jīng)驗(yàn)不足，有的是技術(shù)不成熟，有的則過于敷衍了事，因此，選擇散熱風(fēng)扇還少不了對(duì)散熱風(fēng)扇企業(yè)的考察。但許多廠家卻表示沒有用，因?yàn)槭忻嫔系暮芏嗌犸L(fēng)扇掛著各種認(rèn)證，而價(jià)格卻是白菜價(jià)，很難讓人信服。確實(shí)，外行看熱鬧，內(nèi)行看門道，一款好的散熱風(fēng)扇往往采用進(jìn)口原材料，道道工序都無比精益，需要花去大量的時(shí)間和成本，價(jià)格又怎么可能那么低。所以，產(chǎn)品好不好還必須綜合考慮企業(yè)品牌實(shí)力和市場(chǎng)口碑，被蠅頭小利蒙蔽，反而會(huì)得不償失。三巨電機(jī)已從事散熱風(fēng)扇領(lǐng)域30年，一直致力于交流散熱風(fēng)扇、直流散熱風(fēng)扇的研發(fā)、生產(chǎn)和銷售。三巨電機(jī)認(rèn)為，不**UPS行業(yè)，散熱風(fēng)扇在其他工業(yè)領(lǐng)域同樣起著十分重要的作用，而作為工業(yè)制造業(yè)的重要散熱設(shè)備，散熱風(fēng)扇的研發(fā)生產(chǎn)必須要從客戶的需求和實(shí)際情況出發(fā)。</p><div
