style="text-indent:25px">防爆攝像頭的正確安裝方式：1、安裝選址。在滿足安裝需求的前提下，較好避開(kāi)一些受光位置較復(fù)雜的地方，避免視場(chǎng)內(nèi)有全黑物體、水等吸收紅外光線的物體，以免影響監(jiān)控畫(huà)面。此外還要注意防潮、防塵、防腐、防雷，避開(kāi)潮濕、多塵、高溫或極寒、強(qiáng)輻射等場(chǎng)所。2、安裝角度。俯視角度是防爆攝像頭較常采用的，隱蔽，宏觀觀測(cè)效果好；水平角度安裝便于看清一些細(xì)節(jié)問(wèn)題；采用仰視安裝的少之又少，對(duì)防爆攝像頭的光適能力要求也很高。3、布線合理。建立在原來(lái)的網(wǎng)絡(luò)基礎(chǔ)，選擇合適布線，不要讓信號(hào)線與大功率電線同向傳輸，不能將二者放在相同的傳輸線管內(nèi)。較好走暗線，實(shí)在沒(méi)辦法要走明線的話，要做好線路的物理防護(hù)。</p><p style="text-indent:25px">如何選擇防爆攝像頭：早期的防爆攝像頭以本質(zhì)安全型和正壓型為主。本質(zhì)安全型防爆攝像頭的特點(diǎn)在于對(duì)攝像機(jī)的電路進(jìn)行本質(zhì)安全處理，電氣線路輸出或輸入均被設(shè)計(jì)控制在不足以產(chǎn)生使氫氣發(fā)生引火的能量以下，使其在正常工作中不會(huì)產(chǎn)生電火花、電弧及高溫，從而避免易爆物質(zhì)。這種類型的防爆監(jiān)控機(jī)結(jié)構(gòu)單位成本過(guò)高是較大缺點(diǎn)，此外也不利于日后的升級(jí)。正壓型是早期美系防爆攝像頭產(chǎn)品的常用結(jié)構(gòu)，使用中維護(hù)相當(dāng)不便，如不精心維護(hù)，危險(xiǎn)性相當(dāng)大。此結(jié)構(gòu)目前除極少數(shù)地區(qū)廠商仍在制造外，基本已被較全淘汰。防爆攝像頭是防爆工業(yè)電視系統(tǒng)的中心設(shè)備，但由于市場(chǎng)上的產(chǎn)品良莠不齊，加之信息不對(duì)稱，某些無(wú)認(rèn)證、無(wú)生產(chǎn)、無(wú)售后的“三無(wú)”廠家，以假亂真，隨意更改國(guó)家標(biāo)準(zhǔn)，降低品質(zhì)要求，以次充好。這種魚(yú)龍混雜的局面使設(shè)備選型形同霧里看花，難以抉擇。雖然完全了解一家企業(yè)的質(zhì)量管理體系并非易事，卻可以讓產(chǎn)品告訴我們?cè)S多秘密，正所謂窺一斑而知全豹。通過(guò)落實(shí)好組織措施和技術(shù)措施之后可進(jìn)行臨時(shí)用電作業(yè)。</p><div
