對電話程控交換機(jī)遭受雷擊的情況分析：***.電話程控交換機(jī)是由多塊功能電路板拼插組成.電路板上有許多功能集成塊、半導(dǎo)體元件及電感、電容、電阻.其**能集成塊中大量采用CMOS電路.工作電壓在0.7~5V..CMOS電路的過電壓能力弱.容易損壞.造成電路板甚至整個程控交換機(jī)系統(tǒng)故障..第二.由于電話交換機(jī)是很多電纜、電線的**點(diǎn)..電話分機(jī)線路多在幾十米至上百米的長度.涉及區(qū)域廣、范圍大.更易受雷擊.. 　　這樣．即使是感應(yīng)雷所形成的感應(yīng)過電壓對電話程控交換機(jī)都能形成威脅..雷擊在建筑物(機(jī)房或辦公樓)，承德程控交換機(jī)多少錢、設(shè)備(電話程控交換機(jī))及電纜電路的附近發(fā)生；或閃電不直接對地放電.只是在距建筑物較近的云層和云層之間放電.閃電釋放電荷所形成的強(qiáng)電磁場，承德程控交換機(jī)多少錢.通過電話程控交換機(jī)的密集的網(wǎng)線，承德程控交換機(jī)多少錢、電源電路和數(shù)據(jù)傳輸電路中感應(yīng)生成過電壓。這種“過電壓”或?qū)㈦娫茨K.或?qū)?shù)據(jù)存儲器及微處理器、電話程控交換機(jī)用戶板擊壞。承德程控交換機(jī)多少錢</p><div

1．程控交換機(jī)應(yīng)有良好的工作接地和保護(hù)接地.接地電阻值應(yīng)小于3Ω..每年都應(yīng)檢測并有檢測報(bào)告.. 2．程控交換機(jī)各控制板和外接電纜插口處應(yīng)安裝光電隔離器.. 3．電話電纜的屏蔽接地線應(yīng)和保護(hù)接地極連接良好.. 4．是程控交換機(jī)供電的交流電路(從配電室到交換機(jī))應(yīng)采用屏蔽電纜.屏蔽層應(yīng)和保護(hù)接地極連接良好.. 交換機(jī)遭雷擊損壞大多由雷電天氣在網(wǎng)線上產(chǎn)生的感應(yīng)電壓經(jīng)交換機(jī)信號端口竄入機(jī)內(nèi)造成，一般的整機(jī)防雷措施如裝設(shè)避雷針、機(jī)殼接地等無法解決這個問題。一般交換機(jī)信號端口內(nèi)部都設(shè)計(jì)有防雷擊電路，可以抵抗一般的輕微雷擊，但對大型雷電產(chǎn)生的雷擊則有些力不從心。為進(jìn)一步解決信號端口引進(jìn)的雷擊問題，可以采取以下一些措施： 1、外線盡量使用鎧裝電纜，并將鎧裝層妥善接地； 2、在外線與交換機(jī)端口之間加接防雷單元，具體措施有： ①串接防雷模塊， ②串接LC吸收單元， ③并接過壓保護(hù)元件， ④串接其它防雷保護(hù)電路。南陽銷售程控交換機(jī)</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

2、經(jīng)濟(jì)上的優(yōu)越性（1）交換設(shè)備方面。體積小，采用電子器件大減小了交換機(jī)的體積，這樣占用機(jī)房的面積??；耗電省，用電子器件代替機(jī)械部件，**減低了能量消耗；成本低，隨著集成電路價(jià)格的減低，可以大幅度減低交換機(jī)成本。（2）線路設(shè)備方面?？梢酝ㄟ^采用遠(yuǎn)端用戶模塊方式節(jié)省用戶線，降低線路設(shè)備費(fèi)用。（3）維護(hù)生產(chǎn)方面。由于檢測和診斷故障的自動化，減少了不少維護(hù)工作量，節(jié)省了維護(hù)人員。由于制造工藝簡單了，生產(chǎn)效率也提高了。</p><p style="text-indent:25px">設(shè)備功能數(shù)字程控交換機(jī) 的基本功能主要為：用戶線接入，中繼接續(xù)，計(jì)費(fèi)，設(shè)備管理等。本地交換機(jī)自動檢測用戶的摘機(jī)動作，給用戶的電話機(jī)回送撥號音，接收話機(jī)產(chǎn)生的脈沖信號或雙音多頻（DTMF)信號，然後完成從主叫到被叫號碼的接續(xù)（被叫號碼可能在同一個交換機(jī)也可能在不同的交換機(jī)）。在接續(xù)完成後，交換機(jī)將保持連接，直到檢測出通信的一方掛機(jī)。其中通話接續(xù)部分是利用交換機(jī)中的數(shù)字交換網(wǎng)絡(luò)，采用PCM方式實(shí)現(xiàn)數(shù)字交換的，控制部分是通過軟件由計(jì)算機(jī)來實(shí)現(xiàn)的。基本構(gòu)成電話交換機(jī)的主要任務(wù)是實(shí)現(xiàn)用戶間通話的接續(xù)?；緞澐譃閮纱蟛糠郑涸捖吩O(shè)備和控制設(shè)備。話路設(shè)備主要包括各種接口電路（如用戶線接口和中繼線接口電路等)和交換 (或接續(xù)）網(wǎng)絡(luò)；控制設(shè)備在縱橫制交換機(jī)中主要包括標(biāo)志器與記發(fā)器，而在程控交換機(jī)中，控制設(shè)備則為電子計(jì)算機(jī)，包括**處理器(CPU),存儲器和輸入 /輸出設(shè)備。程控交換機(jī)實(shí)質(zhì)上是采用計(jì)算機(jī)進(jìn)行“存儲程序控制”的交換機(jī)，它將各種控制功能，方法編成程序，存入存儲器，利用對外部狀態(tài)的掃描數(shù)據(jù)和存儲程序來控制，管理整個交換系統(tǒng)的工作。</p><p style="text-indent:25px">經(jīng)常會有人問電話交換機(jī)的作用是什么,簡單的說:程控交換機(jī)的作用就是　　1)共用外線 5個人或10個人共用一條外線。(起初這樣做的目的是為了節(jié)省電話月租，在90年代，固定電話月租很高，如一個公司有500員工，不可能沒人都申請一條直線，那樣的話，月租就是很大的一筆費(fèi)用。公司要讓大家每個人都有電話用，又想減少成本支出，買電話交換機(jī)就成了一種折中的方案。----每月把錢交給電信運(yùn)營商，我還不如省下月租，買個程控交換機(jī)，在一年之后，電話交換機(jī)的成本也就回來了，以后就是賺的了。　　2)管理功能 (現(xiàn)在大家都有電話用了，但是又有個問題：如果不能管理，電話費(fèi)又上來了。所以又要做一些限制，一些人允許打長途，一些人允許打市話，有些人只允許打內(nèi)部電話，所以第二點(diǎn)就是管理。　　3)內(nèi)部通話**(如果是本地電話，同事之間溝通，還需要向電信局交錢。所以在起初正是因?yàn)檫@個原因，也推動了電話交換機(jī)的普及?，F(xiàn)在電信運(yùn)營商推出了匯線通，集線通也可以內(nèi)部通話**。　　4)可以相互轉(zhuǎn)接(一個電話同甲同事講完后可以再轉(zhuǎn)給乙同事。匯線通，集線通也有此功能。　　5)其他功能(代接，代答，內(nèi)部廣播，保留音樂，電話計(jì)費(fèi)，電腦話務(wù)員，語音信箱，外接廣播。張家界程控交換機(jī)安裝</p><p
