style="text-indent:25px">低照度防爆攝像機不借助輔助光源，憑著其自身感光性能和數(shù)字信號處理的優(yōu)勢，在光線極低的環(huán)境中完成監(jiān)控。低照度防爆攝像機器件品質(zhì)選擇要比普通防爆攝像機高，還會應用一些獨特的技術(shù)來進一步提升低照度性能，深圳劉星解釋說：“的產(chǎn)品一般使用光學級大強度高透光超白防爆玻璃，這種玻璃的光通率高于96%，有利于光線的攝取，還有關鍵的機芯，選擇的SONY較高的CCD傳感器”。因此低照度防爆攝像機的成本較高。而防爆紅外攝像機是借助LED燈進行輔助照明，使其有充足的光照度完成監(jiān)控，所以其成本也相對比較低。在沒有特殊要求的夜視監(jiān)控場所下，一般選用成本相對較低的防爆紅外攝像機。但由于防爆紅外攝像機需要借助紅外燈進行輔助照明，在某些場合不適宜使用防爆紅外攝像機進行監(jiān)控，只能使用低照度防爆攝像機進行監(jiān)控。寶雞戶外防爆監(jiān)控攝像機防爆監(jiān)控攝像機使用：IIA類：一氧化碳、苯酚、甲酚、醋酸甲酯、醋酸、氯乙烷。</p><div

style="text-indent:25px">防爆攝像機監(jiān)控系統(tǒng)的常見故障及排除：1、監(jiān)視器上畫面上產(chǎn)生若干條細條紋的干擾。這種干擾現(xiàn)象的產(chǎn)生，多數(shù)是因為在傳輸系統(tǒng)、系統(tǒng)前端或中心控制室附近有較強的、頻率較高的空間輻射源。解決辦法：在系統(tǒng)建立時，應對周邊環(huán)意有所了解，盡量設法避開或遠離輻射源:另一個辦法是當無法避開輻射源時，對前端及中心設備加強屏蔽，對傳輸線和管路采用鋼管并良好接地。2、圖像清晰度不高、細節(jié)部分丟失、嚴重時會出現(xiàn)彩色信號丟失或色飽和度過小。這是由于圖像信號的高頻端損失過大，以3MHz以上頻率的信號基本丟失造成的。這種情況或因傳輸距離過遠，而中間又無放大補償裝置;或因視頻傳輸電纜分布電容過大;或因傳輸環(huán)節(jié)中在傳輸線的芯線與屏蔽線間出現(xiàn)了集中分布的等效電容造成的。</p><p style="text-indent:25px">防爆攝像機的防爆原理：防爆充油型結(jié)構(gòu)。防爆充油型結(jié)構(gòu)在使用上與傳爆等級無關，適合于小型操作開關上。充入的油液應具有較高的化學穩(wěn)定性，為了觀察油位的高度，設備應裝有油位指示器或油位信號裝置。油浸型防爆結(jié)構(gòu)的開關、控制器等設備，由于油的劣化或泄漏等原因，設備損壞很難維修，需要特別注意。另外，由于傾斜或油面搖動而使防爆性能受到損害時，設備不能再繼續(xù)使用。充砂型結(jié)構(gòu)。充砂型結(jié)構(gòu)是在外殼內(nèi)充填砂?；蚱渌?guī)定特性的粉末材料，使之在規(guī)定的使用條件下，殼內(nèi)產(chǎn)生的電弧或高溫均不能點燃周圍危險性氣體環(huán)境的結(jié)構(gòu)。當采用的介質(zhì)使顆粒狀的固體（一般是石英砂）作為隔離介質(zhì)時，稱為充砂型電氣設備；而采用的介質(zhì)時固化物填料（一般位環(huán)氧樹脂），把引燃源澆封在填料里面，而于外面危險性混合物隔離時，也稱為澆封型電氣設備。防爆攝像頭的防護：有些工程商也不是很重視系統(tǒng)的雷電防護。</p><div

style="text-indent:25px">防爆攝像機解析度技術(shù)分析：從某種程度上來說，防爆攝像機的像素、線數(shù)和清晰度這幾個參數(shù)與大家經(jīng)常使用的電腦顯示器、電視機、手機顯示屏的相關參數(shù)是一樣的，三者都是對防爆攝像機畫面質(zhì)感的描述，這樣有利于從多種角度了解把握防爆攝像機的畫面質(zhì)感，這也是很多人無法弄清它們之間關系的一個原因。防爆攝像機的像素，它是組成圖像的基本元素，防爆攝像機的監(jiān)控畫面是由連續(xù)快速出現(xiàn)的圖像組成的，而這些圖像都是由一個一個像素點組成。就相當于把一副圖像放大很多倍之后，再將它從左到右從上到下有規(guī)則的分成很多個格子，在每一個格子內(nèi)填充一個顏色，再把圖像縮小為原來的大小，這樣就組成了一副我們平時看到的圖像。而這些格子就相當于像素點，像素點數(shù)量的多少一般由廠家視情況而定。像素點越多，圖像就越細膩越清晰，也就是分辨率越高。防爆紅外攝像機畫面不清晰解決：紅外燈不好，再好的電流也沒有用。西安防爆紅外攝像機哪家好</p><p

style="text-indent:25px">防爆攝像機的防爆原理：危險性粉塵環(huán)境的防爆結(jié)構(gòu)。粉塵防爆電氣設備是采用限制外殼較高表面溫度和采用“塵密”或“防塵”外殼來限制粉塵進入，以防止可燃性粉塵點燃。該類設備將帶電部件安裝在有一定防護能力的外殼中，從而限制了粉塵進入，使引燃源與粉塵隔離來防止危險的產(chǎn)生。按設備采用外殼防塵結(jié)構(gòu)的差別將設備分為A型設備或B型設備。按設備外殼的防塵等級的高低將設備分為20、21和22級，分別適用于20、21或22區(qū)粉塵危險場所。漢中耐高溫防爆監(jiān)控攝像機哪家好</p></p><br
