id="g3qm3ll" class="box"><p><p> 目前UPS電源所用的蓄電池一般都是免維護的密封鉛酸電池，設(shè)計壽命普遍是5年。UPS電源不宜側(cè)放，應(yīng)保持進風(fēng)孔與出風(fēng)孔通暢;負載與UPS電源連接時，須先關(guān)閉負載、再接線，然后逐個打開負載，嚴禁將電動、復(fù)印機等感性負載接入UPS電源，以免造成傷害。將UPS電源接到**的帶有過電流保護裝置的插座上時，所用電源插座應(yīng)接保護地端;無論輸入電源線是否插入市電插座，UPS電源輸出都可能帶電。要使UPS電源無輸出，須先關(guān)掉開關(guān)，再取消市電供應(yīng)。11、UPS電源正確安裝注意事項：在給UPS連接輸出電源時還應(yīng)該注意安全，由于UPS的輸出電壓和電流都比較大，所以在連接輸出電源時還要注意安全防止觸電***的發(fā)生。更換電池時先關(guān)閉UPS電源并脫離市電，使用帶絕緣手柄的螺絲刀，不要將工具或其它金屬物品放在電池上。連接電池線時，在接頭處出現(xiàn)細小火花屬正?，F(xiàn)象，不會對人身安全及UPS電源造成危害，千萬不要將蓄電池正負極短接或反接。更換蓄電池時，南昌C10KS不間斷電源ups維修在哪里，不宜個別更換，比較好整體更換。另外禁止將不同安培數(shù)、不同品牌的電池組合使用。12，南昌C10KS不間斷電源ups維修在哪里、定期維護：這是針對UPS電源里面的蓄電池的，作為UPS電源里面的**元器件，我們更應(yīng)該認真保護，要定期維護，如果當(dāng)?shù)亻L期不停電，必須定期，南昌C10KS不間斷電源ups維修在哪里。南昌穎頓科技有限公司充滿活力，凝聚力和戰(zhàn)斗力。南昌C10KS不間斷電源ups維修在哪里</p><div

UPS的電路拓撲UPS的可靠運行離不開各模塊的協(xié)調(diào)工作，下面就UPS主要功能模塊電路拓撲進行簡要分析。整流和功率因數(shù)校正電路整流電路在應(yīng)用中構(gòu)成直流電源裝置，是公共電網(wǎng)與電力電子裝置的接口電路，其性能將影響公共電網(wǎng)的運行和用電質(zhì)量。高性能的UPS要求有較高的輸入功率因數(shù)，并盡量減少輸入電流的諧波分量。傳統(tǒng)單相UPS多采用模擬方法，三相UPS多采用相控式整流電路和電壓型單管整流電路。相控式整流電路采用半控式功率器件作為開關(guān)，存在著以下問題:1)網(wǎng)側(cè)諧波電流的存在將降低設(shè)備網(wǎng)側(cè)功率因數(shù)，增加無功功率;2)相控整流換流方式，導(dǎo)致?lián)Q流期中電網(wǎng)電壓畸變，不僅使自身電路性能受到影響，而且對電網(wǎng)產(chǎn)生干擾，對同一接地點的網(wǎng)間其他設(shè)備帶來不良影響;3)相控整流環(huán)節(jié)是一個時滯環(huán)節(jié)，無法實現(xiàn)輸出電壓的快速調(diào)節(jié)。電壓型單管整流電路是三相不控整流橋加Boost電路的簡稱，它的缺點是:電流峰值大，不僅妨礙系統(tǒng)功率的提高，也增加了導(dǎo)通損耗和開關(guān)損耗;為了保持網(wǎng)側(cè)功率因數(shù)的提高，Boost電路必須有一定的升壓比，這對三相電路會導(dǎo)致直流輸出電壓過高。電流型三相橋式整流電路如圖1所示，其優(yōu)點是反饋控制簡單，不需要在控制電路中加入電流反饋。南昌C10KS不間斷電源ups維修售后服務(wù)南昌穎頓科技有限公司榮辱與共，風(fēng)雨同舟。</p><div

而后備式的UPS電源的負載量應(yīng)該控制在60%～70%。注意，過度輕載也不好，雖然不如過載那么嚴重。4、不要使用柴油發(fā)電機：UPS電源不宜由柴油發(fā)電機供電，因其頻率經(jīng)常突變不穩(wěn)，影響UPS電源的正常運行。5、使用UPS電源時的開機和關(guān)機順序：正確的開**機順序應(yīng)該是先打開UPS電源給它供電，然后再打開各個負載，這樣可以避免啟動時瞬間的電流沖擊給UPS造成的損害，在關(guān)機時的順序正好相反應(yīng)該先關(guān)閉各個負載***關(guān)閉UPS.在市電中斷由UPS供電時，應(yīng)該盡快保存好自己的數(shù)據(jù)和資料然后關(guān)閉電腦，否則使用UPS電源進行工作可能會使UPS過量放電，從而縮短UPS的使用壽命。6、UPS電源***充電技巧：新購置UPS電源后，要將UPS電源插入220V市電電網(wǎng)中，充電至少12小時以上，以確保電池充電充分。否則，蓄電池的實際可供使用的容量將**低于蓄電池的標稱容量。若UPS電源長期不用。應(yīng)每隔2～3個月開機24小時，讓其充電充分，并讓UPS電源處于逆變器工作狀態(tài)下2～3分鐘，以保證電池的正常壽命。UPS電源一旦接通市電，即開始對電池組充電，持續(xù)按開機鍵1秒以上進行開機，即開啟逆變器。7、UPS電源不可長期閑置：蓄電池的過度放電和蓄電池長期開路閑置不用可使蓄電池的內(nèi)阻增大。</p><p> 應(yīng)盡量用參數(shù)接近的型號代換，必要時干脆全部換成同一型號。8d%s8e,[:i$yk)R表1是UPS中常用的達林頓逆變管的內(nèi)部電路結(jié)構(gòu)、參數(shù)及外形(注意不同廠家生產(chǎn)的管子參數(shù)有一定差異)。這類管子在測試時一定要注意管子基極與發(fā)射極間的保護電阻和集電極與發(fā)射極間的保護二極管，不要發(fā)生誤判。2008-2-902:48上傳下載附件(KB)(~3D1o*_$~0M&C"Q'r:_%g,@$u8`0g達林頓逆變管的損壞多數(shù)表現(xiàn)為b-e結(jié)開路，少數(shù)為擊穿性損壞，其維修時的代換原則是以大代小，一般來說，只要準備好MJll032(NPN)和MJll033(PNP)兩類管子即可。這兩種管子幾乎可代換所有UPS中的達林頓逆變管，是檢修UPS的必備配件，而市場上其它一些大功率管如彩電中的開關(guān)管、功放機中的功放管等各方面參數(shù)與MJ系列均差別很大，即使接或達林頓電路也代換不了逆變管。"{7_'s/T+]2~1Q!a1D,Z"nVMOS系列逆變管的種類及型號相對達林頓管要多得多，表2是常見VMOS逆變管的參數(shù)及管腳排列。這種VMOS管由于是絕緣柵型場效應(yīng)管，柵極與源、漏兩極是不通的，而漏極與源極間的測試電阻則取決于柵極電位，因此即使同型號的管子，如果不施加相同的柵極偏壓，漏源間電阻的測量值也不一樣，甚至有的通有的不通。南昌穎頓科技有限公司文明工作，文明服務(wù)。</p><div
