style="text-indent:25px">網(wǎng)絡(luò)能耗問題就是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。一旦通信電源系統(tǒng)故障引起對(duì)通信設(shè)備的供電中斷，通信設(shè)備就無法運(yùn)行。福建天磁通信電源</p><p style="text-indent:25px">通信電源系統(tǒng)在通信系統(tǒng)中占據(jù)十分重要的位置。吉林通信電源哪家好</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，除了走線問題還有很多情況起到類似的作用，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，可以通過選擇壓降低的管子或者直接提高a1 a1間電壓的方法解決。吉林通信電源哪家好</p></p><br /><p>文章來源地址: http://www.cdcfah.com/cp/2051671.html</p></div></div></div></div></div><div id="rxxnjnt"
