style="text-indent:25px">防爆攝像頭設(shè)備維護中的一些注意事項在對防爆監(jiān)控系統(tǒng)設(shè)備進行維護過程中，應(yīng)對一些情況加以防范，盡可能使設(shè)備的運行正常，主要需做好防潮、防塵、防腐、防雷、防干擾的工作。防潮、防塵、防腐。對于防爆監(jiān)控系統(tǒng)的各種采集設(shè)備來說，由于設(shè)備直接置于有灰塵的環(huán)境中，對防爆設(shè)備的運行會產(chǎn)生直接的影響，需要重點做好防潮、防塵、防腐的維護工作。如防爆攝像頭長期懸掛于棚端，防爆護罩及防爆玻璃上會很快被蒙上一層灰塵、碳灰等的混合物，又臟又黑，還具有腐蝕性，嚴重影響收視效果，也給防爆設(shè)備帶來損壞，因此必須做好防爆攝像頭的防塵，西安球形防爆監(jiān)控攝像機、防腐維護工作。在某些濕氣較重的地方，則必須在維護過程中就安裝位置，西安球形防爆監(jiān)控攝像機、設(shè)備的防護進行調(diào)整以提高設(shè)備本身的防潮能力，西安球形防爆監(jiān)控攝像機，同時對高濕度地帶要經(jīng)常采取除濕措施來解決防潮問題。環(huán)境條件不許可時，可采用短間距架設(shè)方式以免耐壓性降低而導(dǎo)致感應(yīng)雷入侵。西安球形防爆監(jiān)控攝像機</p><div

style="text-indent:25px">工程商和用戶對“防爆”必要性的認知度不夠。防爆攝像頭是為了實現(xiàn)在易燃易爆的現(xiàn)場環(huán)境中應(yīng)用工業(yè)電視而發(fā)展出來的一種特種攝像機。防爆攝像頭目前普遍應(yīng)用于石油、化工、煤炭和科研、**等國家許多工業(yè)企業(yè)或研究部門等領(lǐng)域。在實驗、生產(chǎn)、加工、運輸和貯存的各過程中，經(jīng)?？赡苄孤┖鸵缟⒊龈鞣N各樣的易燃、易爆氣體、液體和各種粉塵及纖維，這類物質(zhì)與空氣混合后，將變成易發(fā)生危險的混合物，它周圍的場所也成了程度不同的危險場所。所以使用防爆攝像頭是有必要的。這些特殊的產(chǎn)所如果使用普通的監(jiān)控攝像機，不但沒有起到保護監(jiān)控的作用，而且還可能在引發(fā)危險，危害生產(chǎn)安全。所以，在那些特定的產(chǎn)所，防爆攝像頭的存在還是有必要性的。所以要求防爆設(shè)備廠家在工程商和用戶在詢問防爆攝像頭具體情況的時候，說明特殊產(chǎn)所安裝防爆攝像頭的必要性，引導(dǎo)工程商和用戶買到合適的防爆產(chǎn)品。西安球形防爆監(jiān)控攝像機對具有防爆性能的電氣工具及通信器材，使用前必須認真檢查銘牌上的防爆類別、級別、溫度組別。</p><div

style="text-indent:25px">防爆攝像頭的增安型結(jié)構(gòu)：增安型機構(gòu)在防爆電氣設(shè)備上使用得也很普遍，如電動機、變壓器、燈具和帶有電感線圈的電氣設(shè)備等。它是在設(shè)備上采用以系列的安全措施，如使用高質(zhì)量的絕緣材料、降低溫升、增大電氣間隙、提高導(dǎo)線連接質(zhì)量等，使其在較大限度內(nèi)不致產(chǎn)生電火花、電弧或危險溫度，或者采用有效的保護元件使其產(chǎn)生的火花、電弧或溫度不能引燃性混合物，以達到防爆的目的。還有一種與增安型防爆措施類似稱為無火花型，它是一種再正常運行時不產(chǎn)生火花和危險高溫，也不能產(chǎn)生故障的電氣設(shè)備。與增安型相比，只是沒有規(guī)定再增加一些附加措施來提高設(shè)備的安全可靠性。因此，無火花型的安全性比增安型要低，只能用于2區(qū)危險環(huán)境。</p><p style="text-indent:25px">安裝防爆攝像頭的注意事項：日常運行維護檢查時，應(yīng)盡量避免打開防爆攝像頭外殼，必須打開時應(yīng)先切斷電源。如若隔爆外殼打開，應(yīng)妥善保護隔爆面，不得損傷，在檢修時隔爆面應(yīng)向上放置，不得直接接觸地面，隔場面經(jīng)清洗后應(yīng)涂以磷化膏或204防銹油。防爆紅外攝像機是靠CCD配套的紅外燈發(fā)射紅外光在物體上反射到CCD攝像機鏡頭上成像的。因此，我們在安裝防爆紅外攝像機時候應(yīng)該避免視場內(nèi)有全黑物體，空曠處，水等吸收紅外光線的物體，如果紅外線被吸收或是減弱，將會使紅外燈的有效照射效果大打折扣，從而影響到防爆紅外攝像機的監(jiān)控畫面效果。賣萌分割線。如今，防爆監(jiān)控攝像機已經(jīng)成為很多特殊行業(yè)不可或缺的安防設(shè)備，化工廠，加油站，煙花爆竹廠，**廠，煤礦礦井等等地都能見到防爆攝像頭的身影。用防爆通風(fēng)機設(shè)置臨時的局部強力通風(fēng)，降低氣體濃度，保持相對的正壓狀態(tài)。</p><div
