UPS系統安全使用

1.請(qing)保(bao)持進、排氣孔的(de)通(tong)暢(chang)。進、排氣孔的(de)通(tong)風不(bu)暢(chang)會導致不(bu)間(jian)斷電(dian)(dian)源UPS系統內部的(de)溫(wen)(wen)(wen)度(du)升高(gao)(gao)，使機(ji)器中元器件的(de)壽(shou)命(ming)縮(suo)短，從而影(ying)響整機(ji)壽(shou)命(ming)。環境溫(wen)(wen)(wen)度(du)是(shi)影(ying)響UPS蓄電(dian)(dian)池壽(shou)命(ming)的(de)一個重要因素，UPS蓄電(dian)(dian)池佳環境溫(wen)(wen)(wen)度(du)是(shi)在20－25℃之間(jian)。低(di)于(yu)(yu)15℃時，新款USP電(dian)(dian)源廠家代理，其(qi)(qi)放電(dian)(dian)容量(liang)下降，溫(wen)(wen)(wen)度(du)每(mei)降低(di)1℃，其(qi)(qi)容量(liang)下降1%，而溫(wen)(wen)(wen)度(du)過高(gao)(gao)(大于(yu)(yu)30℃)其(qi)(qi)壽(shou)命(ming)就會縮(suo)短；雖然溫(wen)(wen)(wen)度(du)的(de)升高(gao)(gao)對電(dian)(dian)池放電(dian)(dian)能力(li)有所提(ti)高(gao)(gao)，但付(fu)出的(de)代價卻是(shi)電(dian)(dian)池的(de)壽(shou)命(ming)大大縮(suo)短。據試驗測定，環境溫(wen)(wen)(wen)度(du)一旦(dan)超(chao)過25℃，每(mei)升高(gao)(gao)10℃，電(dian)(dian)池的(de)壽(shou)命(ming)就要縮(suo)短一半(ban)。

2.液(ye)體或其他外來物體不允許(xu)進入(ru)UPS電(dian)源機(ji)箱(xiang)內(nei)。

3.萬一UPS系統周(zhou)圍起火，請(qing)使用(yong)干粉(fen)滅(mie)火器，若使用(yong)液體滅(mie)火器會有觸電(dian)危險。

4.UPS蓄(xu)電(dian)(dian)池的(de)(de)壽命隨環境溫(wen)度的(de)(de)升高而縮短(duan)。定期更(geng)換蓄(xu)電(dian)(dian)池可保(bao)證不間(jian)斷電(dian)(dian)源UPS系統工作正常(chang)，且(qie)可維持足(zu)夠的(de)(de)供電(dian)(dian)后備時(shi)間(jian)。

UPS電源的安全(quan)管理

使用(yong)(yong)新的(de)UPS電(dian)(dian)(dian)源(yuan)或UPS電(dian)(dian)(dian)源(yuan)100%全負荷放電(dian)(dian)(dian)較(jiao)長的(de)時間，要(yao)把UPS插進220V市電(dian)(dian)(dian)電(dian)(dian)(dian)網里(li)，充電(dian)(dian)(dian)必須(xu)要(yao)超(chao)過12h以上，從(cong)而(er)保(bao)證電(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)充足。如果UPS電(dian)(dian)(dian)源(yuan)不使用(yong)(yong)的(de)時間過長，必須(xu)每(mei)兩道三個開(kai)機超(chao)過24h，從(cong)而(er)保(bao)證充電(dian)(dian)(dian)充足，從(cong)而(er)使UPS電(dian)(dian)(dian)源(yuan)保(bao)持逆變器工作狀態2～3s，以保(bao)證電(dian)(dian)(dian)池(chi)的(de)正常壽(shou)命。

UPS過(guo)(guo)載(zai)或逆變器故障(zhang)時會(hui)轉到旁路模式(shi)運行(xing)，UPS失去(qu)了(le)后背功能，負(fu)(fu)(fu)載(zai)所用的(de)(de)電(dian)(dian)(dian)源是電(dian)(dian)(dian)力系(xi)統供應(ying)的(de)(de)。如(ru)(ru)果(guo)(guo)市電(dian)(dian)(dian)指(zhi)(zhi)示(shi)燈閃爍，說明市電(dian)(dian)(dian)的(de)(de)電(dian)(dian)(dian)壓或頻(pin)率(lv)高于(yu)正常范(fan)圍;如(ru)(ru)果(guo)(guo)負(fu)(fu)(fu)載(zai)指(zhi)(zhi)示(shi)燈超過(guo)(guo)100%，電(dian)(dian)(dian)力USP電(dian)(dian)(dian)源廠家批發(fa)，表(biao)明接了(le)過(guo)(guo)多的(de)(de)負(fu)(fu)(fu)載(zai)，蜂(feng)鳴器會(hui)半秒叫一(yi)次，應(ying)將不必要負(fu)(fu)(fu)載(zai)逐一(yi)去(qu)除(chu)，直到UPS負(fu)(fu)(fu)載(zai)量小于(yu)100%;若電(dian)(dian)(dian)池(chi)(chi)(chi)指(zhi)(zhi)示(shi)燈閃爍，則表(biao)示(shi)UPS未接電(dian)(dian)(dian)池(chi)(chi)(chi)或電(dian)(dian)(dian)池(chi)(chi)(chi)電(dian)(dian)(dian)壓太低，此時應(ying)檢(jian)查電(dian)(dian)(dian)池(chi)(chi)(chi)是否連接好，如(ru)(ru)果(guo)(guo)連接是正確(que)的(de)(de)，那么(me)有可(ke)能是蓄(xu)電(dian)(dian)(dian)池(chi)(chi)(chi)故障(zhang)或者蓄(xu)電(dian)(dian)(dian)池(chi)(chi)(chi)老化(hua)。

穩壓電(dian)(dian)路的(de)作用是為(wei)電(dian)(dian)路提(ti)供更(geng)加(jia)穩定的(de)直流電(dian)(dian)。整流濾波(bo)電(dian)(dian)路的(de)輸(shu)出電(dian)(dian)壓和理想直流電(dian)(dian)源(yuan)還有一(yi)定的(de)差距，主要因為(wei)兩方面的(de)原(yuan)因

:第一，當負載(zai)電(dian)流發生(sheng)變化時(shi)，由于整(zheng)流濾波電(dian)路存在內阻(zu)，輸出的直流電(dian)壓將會隨(sui)之發生(sheng)變化;

第二，當電網電壓有(you)波動時，整流電路的輸出電壓與變壓器副邊電壓有(you)直接的關系，因此輸出直流電壓也會(hui)發生變化。
