對(duì)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(gè)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(zhǎng)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(duì)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)、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(duì)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(chǎng).通過電話程控交換機(jī)的密集的網(wǎng)線、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(chǔ)器及微處理器、電話程控交換機(jī)用戶板擊壞。衡水銷售程控交換機(jī)</p><div

5個(gè)人或10個(gè)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(gè)公司有500員工，不可能沒人都申請(qǐng)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(gè)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(yíng)商，我還不如省下月租，買個(gè)程控交換機(jī)，在一年之后，電話交換機(jī)的成本也就回來(lái)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(gè)問題：如果不能管理，電話費(fèi)又上來(lái)了。所以又要做一些限制，一些人允許打長(zhǎng)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(gè)原因，也推動(dòng)了電話交換機(jī)的普及。現(xiàn)在電信運(yùn)營(yíng)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(gè)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(yǔ)音信箱，外接廣播。</p><p style="text-indent:25px">程控電話是指接入程控電話交換機(jī)的電話，程控電話交換機(jī)是利用電子計(jì)算機(jī)來(lái)控制的交換機(jī)，它以預(yù)先編好的程序來(lái)控制交換機(jī)的接續(xù)動(dòng)作。此程控電話與一般機(jī)電式交換機(jī)的電話相比，具有接續(xù)速度快、業(yè)務(wù)功能多、交換效率高、聲音清晰、質(zhì)量可靠等優(yōu)點(diǎn)。程控交換機(jī)，也稱為程控?cái)?shù)字交換機(jī)或數(shù)字程控交換機(jī)，通常專指用于電話交換網(wǎng)的交換設(shè)備，它以計(jì)算機(jī)程序控制電話的接續(xù)。數(shù)字程控交換機(jī)分為長(zhǎng)途交換機(jī)，本地交換機(jī)等。另外還有**于信令網(wǎng)和智能網(wǎng)的類型。數(shù)字程控交換機(jī)的基本功能為：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(dòng)檢測(cè)用戶的摘機(jī)動(dòng)作，給用戶的電話機(jī)回送撥號(hào)音，接收話機(jī)的產(chǎn)生的脈沖信號(hào)或雙音多頻(DTMF)信號(hào)，然后完成從主叫到被叫號(hào)碼的接續(xù)(被叫號(hào)碼可能在同一個(gè)交換機(jī)也可能在不同的交換機(jī))。在接續(xù)完成后，交換機(jī)將保持連接，直到檢測(cè)出通信的一方掛機(jī)。程控電話交換機(jī)的作用是為中小企業(yè)構(gòu)架的內(nèi)部通訊網(wǎng)絡(luò)，幫助企業(yè)內(nèi)部與外界信息的傳遞與交流、生產(chǎn)調(diào)度與指令的傳達(dá)，避免走來(lái)走去或跑上跑下的麻煩、節(jié)省了相互通話的費(fèi)用(內(nèi)部電話無(wú)需支付電話費(fèi)、無(wú)月租費(fèi)、無(wú)承諾話費(fèi))，重要的在于為企業(yè)提高工作效率、又控制辦公話費(fèi)</p><p style="text-indent:25px">防雷擊可采取以下措施： 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(cè)并有檢測(cè)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(hào)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(wú)法解決這個(gè)問題。一般交換機(jī)信號(hào)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(duì)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(hào)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。嘉定區(qū)程控交換機(jī)多少錢</p><p style="text-indent:25px">嘉定區(qū)程控交換機(jī)多少錢</p><p
