一、通信電源的作用是什么
通(tong)信(xin)(xin)(xin)電(dian)源是(shi)整個通(tong)信(xin)(xin)(xin)網絡的(de)關鍵(jian)基礎設施,通(tong)信(xin)(xin)(xin)電(dian)源系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)是(shi)通(tong)信(xin)(xin)(xin)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)的(de)心(xin)臟,穩定可(ke)靠(kao)的(de)通(tong)信(xin)(xin)(xin)電(dian)源供(gong)電(dian)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong),是(shi)保證通(tong)信(xin)(xin)(xin)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)安(an)全、可(ke)靠(kao)運行的(de)關鍵(jian),一(yi)旦通(tong)信(xin)(xin)(xin)電(dian)源系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)故障(zhang)引起(qi)對通(tong)信(xin)(xin)(xin)設備的(de)供(gong)電(dian)中(zhong)斷,通(tong)信(xin)(xin)(xin)設備就(jiu)無法運行,就(jiu)會造(zao)成通(tong)信(xin)(xin)(xin)電(dian)路中(zhong)斷、通(tong)信(xin)(xin)(xin)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)癱瘓,從(cong)而造(zao)成極(ji)大的(de)經濟和社會效益損失。因此,通(tong)信(xin)(xin)(xin)電(dian)源系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)在通(tong)信(xin)(xin)(xin)系(xi)(xi)(xi)統(tong)(tong)(tong)(tong)中(zhong)占據(ju)十分重要的(de)位置。
二、通信電源使用注意事項有哪些
1、高頻開關電源系統(tong)對環境的(de)溫度(du)(du)要(yao)求并不高,在(zai)(zai)零下(xia)(xia)5度(du)(du)~到40度(du)(du)都(dou)可正(zheng)常工作(zuo),但(dan)在(zai)(zai)室內(nei)一定(ding)要(yao)清(qing)潔、少塵,否則(ze)灰(hui)塵再加上潮濕是會引起(qi)主機工作(zuo)紊亂。其(qi)(qi)中蓄電池對溫度(du)(du)的(de)要(yao)求比較高,其(qi)(qi)標準使(shi)用溫度(du)(du)為25度(du)(du),在(zai)(zai)平時不可超(chao)過+15度(du)(du)到+30度(du)(du)。若溫度(du)(du)太低,會使(shi)蓄電池的(de)容量下(xia)(xia)降(jiang),溫度(du)(du)每(mei)下(xia)(xia)降(jiang)1度(du)(du),其(qi)(qi)容量也會下(xia)(xia)降(jiang)1%。
2、按電源系(xi)統(tong)的使用要求、功(gong)率(lv)(lv)余量(liang)的大(da)小來分,在(zai)使用中需避免隨意增加(jia)大(da)功(gong)率(lv)(lv)的額(e)外(wai)設備,也不(bu)允許在(zai)滿負(fu)載狀(zhuang)態(tai)下(xia)(xia)(xia)進行長期運(yun)行。工作(zuo)性質(zhi)決(jue)定了(le)電源系(xi)統(tong),基本(ben)幾(ji)乎是在(zai)不(bu)間斷的狀(zhuang)態(tai)下(xia)(xia)(xia)運(yun)行的,在(zai)增加(jia)大(da)功(gong)率(lv)(lv)負(fu)載或(huo)者在(zai)基本(ben)滿載狀(zhuang)態(tai)下(xia)(xia)(xia)工作(zuo),都會造成整流模塊出現(xian)故障,嚴重時將(jiang)會損壞變換器。
3、由于組合蓄電池組的(de)輸出(chu)(chu)電(dian)流很(hen)大,存(cun)在電(dian)擊危險,因(yin)此在裝卸、輸出(chu)(chu)線、改(gai)接(jie)導電(dian)聯接(jie)條時都(dou)應(ying)格(ge)外注意(yi)安(an)全,工具都(dou)應(ying)采用絕緣措施,特別是輸出(chu)(chu)接(jie)點應(ying)該有(you)防觸(chu)摸(mo)措施。以保護人身、設備的(de)安(an)全。
4、不管是(shi)在浮充工作狀態還(huan)是(shi)在放(fang)電(dian)檢修的(de)測(ce)試狀態下(xia),都需保證電(dian)壓、電(dian)流(liu)等都符合規定要求(qiu)。電(dian)壓或者電(dian)流(liu)過高(gao)很有可能(neng)會造成電(dian)池的(de)熱失(shi)控、失(shi)水,電(dian)壓、電(dian)流(liu)出現過小是(shi)會造成電(dian)池的(de)虧電(dian),這都會影(ying)(ying)響(xiang)電(dian)池的(de)整個使用壽命,而前者的(de)影(ying)(ying)響(xiang)更大。
5、電(dian)池應該(gai)(gai)避免大電(dian)流(liu)的充放電(dian),理(li)論上充電(dian)時可以接(jie)受大電(dian)流(liu),但實際(ji)操作中應應該(gai)(gai)盡量(liang)避免,否(fou)則會造(zao)成電(dian)池極板的膨脹變(bian)形,使得極板活性物質出(chu)現脫(tuo)落(luo),電(dian)池內(nei)阻增大和溫度升(sheng)高,嚴重時會直接(jie)造(zao)成容(rong)量(liang)下降,提前終止(zhi)使用(yong)壽命。
