style="text-indent:25px">使用KVM切換器的必要性：電力系統(tǒng)中使用KVM切換器進行無功率補償方法有很多優(yōu)點，當這些KVM切換器接入電網(wǎng)時候，會瞬間產(chǎn)生大幅度和高頻率沖擊電流，其峰值稱為浪涌電流峰值，可達到KVM切換器額定工作電流180倍左右。目前，先進無功功率補償裝罝均釆用自動控制方式。這種控制方式自動控制投入KVM切換器組大小和數(shù)量,把功率因數(shù)控制設定范圍內。控制KVM切換器投入執(zhí)行裝置通常為接觸器，南京STARLINEKVM廠家，一般KVM切換器浪涌電流沖擊下很容易造成主觸頭熔焊。接觸器主觸頭熔焊，就可能出現(xiàn)過補償設備損失。接觸器工作可靠與否將直接影響無功功率補償系統(tǒng)可靠性，南京STARLINEKVM廠家。**KVM切換器就是為此目而專門設計。這種**KVM切換器一般都附加有控制浪涌電流裝置，可以有效減少合閘時產(chǎn)生浪涌電流對電容器組沖擊，降低操作時產(chǎn)生過電壓，南京STARLINEKVM廠家，同時也可以避免KVM切換器產(chǎn)生熔焊現(xiàn)象。數(shù)字KVM的缺點：允許同時登陸用戶少。南京STARLINEKVM廠家</p><div

12V電源適配器是否有輸出。2.開機時，是否有—嗶—的一聲開機提示，按鍵板的LED燈是否亮起。3.檢查顯示器的電源是否打開、顯示器信號線是否已經(jīng)連接到切換器的CONSOLE端。二、開機后不能登錄進入KVM系統(tǒng)。答：1.確認USB或者PS/2鍵盤是否能正常使用。2.重新插拔USB或者PS/2鍵盤，此時鍵盤上的三個指示燈會閃爍一次。3.用戶名或者密碼沒有輸入正確，初始默認值為空，回車即可進入。三、登錄進入系統(tǒng)后，發(fā)現(xiàn)有KVM端口不能切換。答：調出OSD主菜單，查看左上角的用戶名，看管理員是否屏蔽了此用戶的端口權限。四、液晶折疊套件（LED-KVM）的屏幕黑屏。答：檢查前端導軌是否已經(jīng)拉出。操作方式：1.向左推前面板按鈕，將KVM控制平臺從機柜里完全拉出，導軌會自動鎖上，KVM電源會自動接通；2.檢查電源開關是否已經(jīng)打開；3、檢查電源POWER指示燈是否不亮（不亮的話可能是電源指示燈順壞或電路板出現(xiàn)問題）；4、屏幕損壞（可能是點屏線未連接好或損壞、連桿信號線損壞或A/D損壞）。南京STARLINEKVM廠家數(shù)字KVM的缺點：占用網(wǎng)絡寬帶流量，受寬帶影響，會有滯后感，網(wǎng)絡中斷即無法工作。</p><div

style="text-indent:25px">KVM切換器選用原則：保證無功功率補償系統(tǒng)能夠可靠工作，KVM切換器必須滿足以下兩個基本條件：（1)KVM切換器額定工作電流必須持續(xù)達到切換器的額定工作電流1.5倍。諧波和網(wǎng)絡電壓誤差存，會導致電路中產(chǎn)生一個持續(xù)性流動電流，其值大約是KVM切換器額定電流1.3倍左右?？紤]到制造誤差，KVM切換器實際功率應該可以達到其額定功率1.15倍。GB3938.1和IEC831-1中規(guī)定了KVM切換器較大熱電流為：式中,IT為切換器較大熱電流;In為KVM切換器額定工作電流。(2)KVM切換器觸點閉合時必須能夠承受短暫而巨大峰值電流，即浪涌峰值電流。浪涌電流峰值大小與電力網(wǎng)絡電感、變壓器容量、短路電壓以及功率因數(shù)補償類型等諸多因素有關。其**率因數(shù)補償類型主要有以下兩種：一種是KVM切換器組投入是一步到位固定式功率因數(shù)補償。這種情況下，KVM切換器組插入時浪涌電流峰值可以達到KVM切換器額定容量大約30倍，浪涌電流峰值可以按公式進行估算。</p><p style="text-indent:25px">多計算機切換器（KVM）以多主機切換技術為依據(jù)，借助一組鍵盤、鼠標和顯示器完成多臺服務器之間的切換，進而節(jié)省空間，降低成本，使得管理更為簡易方便，以提升工作效率。該技術具有很多優(yōu)點，應用十分普遍。首先，在整個機房管理中，改變了傳統(tǒng)的一對一的控制方式，而采用了一對多的管理方式，有利于節(jié)省空間、提高工作效率；其次，主機系統(tǒng)的安全性能得到了很大提升，而且具備了長距離的傳輸能力，在與遠程用戶相連接時，安全性能得到良好的保證；在服務器較多的情況下，通過數(shù)字交換機與其他服務器相連，并能與遠程相連，可同時對本地和遠程進行控制。在一些大型系統(tǒng)的解決方案中，可使用具有模擬交換機矩陣功能的大型模塊系統(tǒng)，能夠滿足終端用戶同時對上百臺甚至更多服務器的訪問，進而實現(xiàn)從中心點通過KVM系統(tǒng)對各地的服務器進行有效控制。此外，該技術也可以在家庭中用，為普通用戶提供了很多方便。使用KVM延長器是電臺直播室系統(tǒng)計算機維護管理的很好選擇。</p><div
