列頭柜主要用于網(wǎng)絡(luò)信息機房中，分強電列頭柜和弱電列頭柜，位于機柜排的一端。在機房配電設(shè)計中，早是把市電配電柜、UPS配電柜設(shè)計為一個部分，單獨做一個配電間，是與網(wǎng)絡(luò)中心區(qū)分開的，隨著信息技術(shù)的發(fā)展，四川直流列頭柜咨詢報價，這種管理方式越來越不方便。之后就把UPS配電柜移到網(wǎng)絡(luò)中心區(qū)并且放在整排機柜的一端，UPS配電柜的外觀做成和服務(wù)器機柜一樣的外觀。這種方式既美觀又方便管理。弱電列頭柜同理也是放在整排機柜的一頭，做為網(wǎng)線匯聚柜，方便跳線管理。至于為什么叫做列頭柜，是因為這個配電柜一般裝于一列設(shè)備的個位置（相當于頭），四川直流列頭柜咨詢報價，這一列的設(shè)備均由此列柜引電，所以叫列頭柜,之后技術(shù)人員慢慢對這種擺放的機柜統(tǒng)稱為列頭柜，四川直流列頭柜咨詢報價。有些電力部門習慣把網(wǎng)絡(luò)機房中的機柜叫成“屏柜”。數(shù)據(jù)中心列頭柜的分類與安裝。四川直流列頭柜咨詢報價</p><div

強電列頭柜的管理功能很強，現(xiàn)在還有精密列頭柜更是加強了強電列頭柜的管理功能，它不但可以監(jiān)控到常規(guī)的電氣參數(shù)和開關(guān)狀態(tài)，還能檢測零線電流、動態(tài)調(diào)節(jié)三相不平衡等問題。弱電列頭柜更傾向于分配，但在增加了電子配線系統(tǒng)后，弱電列頭柜的管理功能也得到了很大的加強。三、什么是列頭柜列頭柜為成行排列或按功能區(qū)劃分的機柜提供網(wǎng)絡(luò)布線傳輸服務(wù)或配電管理的設(shè)備，一般位于一列機柜的端頭。四、基本含義列頭柜從字面意義上就知道是位于一列機柜端頭的柜子。四川直流列頭柜咨詢報價流列頭柜,UPS輸入輸出柜。</p>

src="https://tyunfile.71360.com/WaterMark/UploadFile/shhuijue/637475100158885720/5456861.png"></div><p> 首先，傳統(tǒng)配電柜使用指針式儀表或者數(shù)顯式儀表，只能有限的監(jiān)測配電柜參數(shù)，滿足基本的需要，智能配電柜采用高集成度，高可靠性的計算機主板，的監(jiān)測系統(tǒng)的各項運行參數(shù)，并通過HMI綜合顯示，降低了對配電柜的空間占有，提高了配電柜的容積率。 </p> <p> <br /> </p> <p> 第二，傳統(tǒng)的配電柜只具備配電管理的功能，將電源分配到負載機柜上；而智能配電柜，除了配電管理外，還具有運行管理與安全管理的功能，有效的提高了整個配電系統(tǒng)的可靠性，降低了風險。 </p> <p> <br /> </p> <p> 第三，傳統(tǒng)配電柜支持的回路少，整體占地面積大；智能配電柜采用高精度高集成的模塊，提高了柜體的容積，支持較多的回路，減少了占地面積。 </p><p> 列頭柜與配電柜有哪些區(qū)別 </p> <p> 1、電流監(jiān)測不同： </p> <p> <br /> </p> <p> 列頭柜監(jiān)測總電流，三相電各支路電流及輸出各分支至機柜電流。配電柜只監(jiān)測總電流。 </p> <p> <br /> </p> <p> 2、電路結(jié)構(gòu)不同： </p> <p> <br /> </p> <p> 列頭柜使機房形成二層電路結(jié)構(gòu)，形成樹狀用電監(jiān)測管理，調(diào)整運行方式、優(yōu)化用電結(jié)構(gòu)。配電柜機房電路只有一層結(jié)構(gòu)，電流分配顯示不明晰 </p> <p> <br /> </p> <p> 3、監(jiān)測電能不同： </p> <p> <br /> </p> <p> 列頭柜配置電能模塊，測算電能消耗，實現(xiàn)合理、節(jié)約用電，降低用電成本。配電柜無電能消耗顯示，無法提供機房用電數(shù)據(jù)。 </p> <p> <br /> </p> <p> 4、設(shè)備集成化不同： </p> <p> <br /> </p> <p> 列頭柜集成度高，同等容量積減小。配電柜體積較大，占用機房空間。 </p> <p> <br /> </p> <p> 5、連接方式不同： </p> <p> <br /> </p> <p> 列頭柜采用熱插拔式連接，安裝操作簡單。配電柜采用端子硬鏈接，需專業(yè)電工操作。 </p> <p> <br /> 機房列頭柜、配電柜應(yīng)用解決方案。</p> <div> <span style="color:#333333;font-family:"Microsoft YaHei",

style="text-indent:25px">在大型機房里列頭柜是必要的也是必須的，一是由于UPS配電柜的輸出分路有限，而列頭柜可以按設(shè)備的電力需求進行優(yōu)化配置，解決電源柜分路不足的問題。二是方便電路的檢修，單一分支電路出現(xiàn)故障不必總配電柜斷電檢修，只需要斷開該路電源檢修，提高機房整體電路的容錯性。精密列頭柜是機房的設(shè)備,也是機房設(shè)備。精密列頭柜是以HMI為，通過以太網(wǎng)和RS485總線的模塊化結(jié)構(gòu)，對列頭柜的動力微環(huán)境進行有效管控，可以實現(xiàn)遠程監(jiān)控和異地監(jiān)控功能，通過IP地址可以在全國各地隨時監(jiān)控設(shè)備的運行情況。機房工程強弱電列頭柜基礎(chǔ)知識介紹。四川直流列頭柜咨詢報價</p><p

數(shù)據(jù)中心小母線供配電系統(tǒng)是典型的樹干式供配電系統(tǒng),總配電柜至各機柜之間采用一條干線連接的配電方式。優(yōu)點是消耗金屬導(dǎo)體消耗量少、施工快捷方便、即插即用、易于擴展與變更、相對于電纜,母線可靠性高、使用壽命長并且可重復(fù)利用。缺點是干線一旦發(fā)生故障時,影響范圍大。 </p> <p> 數(shù)據(jù)中心列頭柜形式的供配電系統(tǒng)是典型的放射式供配電系統(tǒng),總配電柜直接供電給列頭柜與負載的配電方式。優(yōu)點是各負荷受電,一旦發(fā)生故障只局限于本身而不影響其他回路,充分滿足國家現(xiàn)行規(guī)范對重要用電負荷的技術(shù)要求。缺點是線路多、金屬導(dǎo)體消耗量大、施工復(fù)雜。系統(tǒng)靈活性差:不具有變更能力、分期實施困難、不可重復(fù)利用系統(tǒng)靈活性差。另外,在列頭柜形式的供配電系統(tǒng)中,列頭柜占用了機柜列的寶貴空間。
