style="text-indent:25px">5G基站電源，市場(chǎng)空間多大？不可否認(rèn)，5G通信電源目前是一個(gè)藍(lán)海市場(chǎng)。目前，5G單站供電功率預(yù)計(jì)將達(dá)到約4000瓦甚至更高，因而基站電源存在極大的擴(kuò)容需求。換言之，90%的4G存量電源均需擴(kuò)容和改造，以滿足5G使用需求。那么，通信電源市場(chǎng)前景究竟有多誘人，安信證券對(duì)5G電源市場(chǎng)空間的測(cè)算可見(jiàn)一斑：（1）若在現(xiàn)有的-48V開(kāi)關(guān)電源方案基礎(chǔ)上擴(kuò)容，按照5G基站近4000瓦的輸入功率需求測(cè)算，至少需要增加2個(gè)-48V/50A的整流模塊，假設(shè)以2000元/個(gè)的模塊單價(jià)，則單站的擴(kuò)容成本為4000元。（2）若采用HVDC直流遠(yuǎn)供或者DPS分布式供電，單站價(jià)值約在7000-1萬(wàn)元左右。進(jìn)一步假設(shè)3種供電方案的建設(shè)比例為1：1：1，那么按照國(guó)內(nèi)450萬(wàn)站的建設(shè)規(guī)模測(cè)算，預(yù)計(jì)5G基站電源市場(chǎng)空間有望達(dá)到315億元。內(nèi)蒙古天磁科技有限公司通信電源通信電源作為基站基礎(chǔ)的供能設(shè)施，是保證基站在室內(nèi)/外，尤其是惡劣天氣、環(huán)境下正常運(yùn)行的基礎(chǔ)設(shè)施。</p><div

style="text-indent:25px">網(wǎng)絡(luò)能耗問(wèn)題就是5G普及路上的一個(gè)重大挑戰(zhàn)。從目前全球頻譜分布來(lái)看，要想獲得更多帶寬，5G頻段高頻化成為必然趨勢(shì)。高頻化所帶來(lái)的覆蓋區(qū)域變小，促使小區(qū)數(shù)量增加，而且站點(diǎn)頻段數(shù)量也會(huì)快速增加，站點(diǎn)頻段數(shù)從4頻到7頻甚至10頻以上。這些將導(dǎo)致5G時(shí)代全球站點(diǎn)數(shù)量倍增，站點(diǎn)能耗翻倍。由于能源緊缺和節(jié)能環(huán)保所帶來(lái)的雙重壓力，全球范圍內(nèi)電費(fèi)呈現(xiàn)逐年上漲趨勢(shì)，因而站點(diǎn)能耗的大幅上漲將進(jìn)一步推高運(yùn)營(yíng)商的總體能源費(fèi)用和運(yùn)營(yíng)成本。根據(jù)統(tǒng)計(jì)結(jié)果，能源費(fèi)用目前普遍占全球運(yùn)營(yíng)商收入的1%~8%；在網(wǎng)絡(luò)能耗倍增、電價(jià)上漲的背景下，能源OPEX預(yù)計(jì)會(huì)出現(xiàn)三倍的增長(zhǎng)。與此同時(shí)，全球超過(guò)70%的存量站點(diǎn)將面臨電源、配電、溫控和電池容量不足的挑戰(zhàn)，超過(guò)30%的站點(diǎn)需要進(jìn)行市電改造，運(yùn)營(yíng)商面臨著極高的CAPEX壓力，降能耗、提盈利成為廣大運(yùn)營(yíng)商的重要關(guān)切點(diǎn)之一。</p><p style="text-indent:25px">走線阻抗大。電源模塊輸出與負(fù)載連接必然要有一段PCB走線，走線越長(zhǎng)、走線越窄則它的等效電阻越大。等效電阻可以認(rèn)為是串聯(lián)在負(fù)載的工作回路中，將起到分壓作用，因此導(dǎo)致負(fù)載兩端的電壓小于模塊的輸出電壓。此外，除了走線問(wèn)題還有很多情況起到類(lèi)似的作用，比如焊點(diǎn)接觸不良導(dǎo)致等效電阻增加，線路氧化或腐蝕導(dǎo)致等效電阻增加。防反接二極管。很多產(chǎn)品的AC和DC部分是不在一塊板上的，在生產(chǎn)或終端客戶使用中不可避免涉及到插拔電源連接器的情況。為防止此過(guò)程中的反接導(dǎo)致的硬件損壞，常串入一只二極管解決。以壓降0.7V的二極管為例，b1 b2間的電壓將比a1 a2間電壓小0.7V，這也就是上面所討論的輸入電壓偏低的情況，可以通過(guò)選擇壓降低的管子或者直接提高a1 a1間電壓的方法解決。 5G未來(lái)已來(lái)，通信電源時(shí)至勢(shì)成。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="text-indent:25px">高頻開(kāi)關(guān)電源設(shè)備在正常使用情況下，主機(jī)的維護(hù)工作量很少，主要是防塵和定期除塵。特別是氣候干燥的地區(qū)，空氣中的灰粒較多，灰塵將在機(jī)內(nèi)沉積，當(dāng)遇空氣潮濕時(shí)會(huì)引起主機(jī)控制紊亂造成主機(jī)工作失常，并發(fā)生不準(zhǔn)確告警。另大量灰塵也會(huì)造成器件散熱不好。一般每季度應(yīng)徹底清潔一次。其次就是在除塵時(shí)檢查各連接件和插接件有無(wú)松動(dòng)和接觸不牢的情況。由于整流器對(duì)瞬時(shí)脈沖干擾不能消除，整流后的電壓仍存在干擾脈沖。蓄電池除有存儲(chǔ)直流電能的功能外，其等效電容量的大小與蓄能電池容量大小成正比。因此，維護(hù)檢修蓄電池的工作是非常重要的，雖說(shuō)蓄電池組都采用了免維護(hù)電池，但這只是免除了以往的測(cè)比、配比、定時(shí)添加蒸餾水的工作。但因工作狀態(tài)對(duì)電池的影響并沒(méi)有改變，不正常工作狀態(tài)對(duì)電池造成的影響沒(méi)有變，所以蓄電池的工作全部是在浮充狀態(tài)，在這種情況下至少應(yīng)每年進(jìn)行一次放電。放電前應(yīng)先對(duì)電池組進(jìn)行均衡充電，以達(dá)全組電池的均衡。放電過(guò)程中如有一只達(dá)到放電終止電壓時(shí)，應(yīng)停止放電，繼續(xù)放電須先排除落后電池后再放。5G通信電源及關(guān)鍵零部件項(xiàng)目，歡迎咨詢天磁。北京高壓輸出大功率通信電源</p><p
