style="text-indent:25px">防爆攝像機監(jiān)控系統(tǒng)的常見故障及排除：1、電源不正確引發(fā)的設(shè)備故障，電源不正確大致有如下幾種可能。a、供電線路或供電電壓不正確。b、功率不夠(或某一路供電線路的線徑不夠，降壓過大等)。c、供是系統(tǒng)的傳輸線路出現(xiàn)短路、斷路、瞬間過壓等。d.特別是因供電錯誤或瞬間過壓導(dǎo)致設(shè)備損壞的情況時有發(fā)生，因此，在系統(tǒng)調(diào)試以前，供電以前，一定要認真嚴格的進行核對與檢查，絕不應(yīng)掉以輕心。2、云臺的故障。一個云臺在使用后不久就運轉(zhuǎn)不靈或根本不能轉(zhuǎn)動，是云臺常見故障。這種情況的出現(xiàn)除去產(chǎn)品質(zhì)量的因素外，一般是以下各種原因造成的：a、只允許將攝像機正裝的云臺，在使用時采用了吊裝的方式。在這種情況下，吊裝方式導(dǎo)致了云臺運轉(zhuǎn)負荷加大，故使用不久就會導(dǎo)致云臺的傳動機構(gòu)損壞，甚至燒毀電機。b、攝像機及其防護罩等總重量超過云臺的承重。特別是室外使用的云臺，往往防護罩的重量過大，常會出現(xiàn)云臺轉(zhuǎn)不動(特別是垂直方向轉(zhuǎn)不動)的問題。c、室外云臺因環(huán)境溫度過高、過低、防水、防凍措施不良而出現(xiàn)故障甚至損壞。</p><p style="text-indent:25px">阻礙防爆攝像機發(fā)展的原因：防爆攝像機成本相對高。一臺防爆攝像機的價格，要比同參數(shù)的普通攝像機高出一大截。國內(nèi)的工程商和用戶對這些高價位產(chǎn)品還沒有一個較高的接受度，還是需要時間去培養(yǎng)和轉(zhuǎn)變他們的消費觀念和意識，這也較大制約了防爆攝像機的普及。筆者了解到，近兩三年，不少之前做普通攝像機的廠家進入到防爆攝像機領(lǐng)域，其中大部分企業(yè)均按照防爆攝像機的強制要求進行產(chǎn)品管理，但也出現(xiàn)部分企業(yè)打著“防爆”的旗號，在不具備防爆設(shè)備的生產(chǎn)和檢測能力下，降低產(chǎn)品標準，從而以低成本沖擊市場。由于部分工程商或是甲方對防爆攝像機了解不夠，加上部分廠家混淆概念的宣傳，使得一些工程采購了不合規(guī)格的產(chǎn)品，嚴重的甚至造成了惡劣的后果，這無論是對防爆攝像機廠家還是工程方，都是不可估量的損失。根據(jù)防爆攝像機所需要的成本，短時間內(nèi)無法解決高價格的問題，在購買防爆攝像機時固然要價格比三家，但是前提是該產(chǎn)品是通過安全認證的產(chǎn)品，所以，要求工程商在購買防爆產(chǎn)品的時候不能只看價格，購買到假冒偽劣的安防產(chǎn)品，給工業(yè)生產(chǎn)帶來安全隱患。在設(shè)計圖像信號傳輸線纜時必須考慮信號的傳輸速率及電壓的平衡與接地，避免感應(yīng)雷入侵。</p><div

style="text-indent:25px">防爆攝像機狹路相逢優(yōu)勝劣汰：防爆攝像機較高等級為EXDⅡCT6和防粉塵較高等級DIPA20TAT6。目前在市場上很多小廠家低價銷售所謂的“防爆攝像機”，其技術(shù)要求其實是沒有達到防爆標準的，至只是一味追求銷售和利潤。防爆攝像機等級其實這當(dāng)中是有具分的，防爆等級還分為EXDⅡCT5/T4/T3/T2/T1，又可以分為EXDⅡBT6/T5/T4/T3/T2/T1，這些等級具分的價格上有很大的具別的，所以大家在購買時就要注意了,這些沒達到較高防爆等級甚至沒有達到防爆標準的攝像機雖然價格便宜但是存在明顯的安全隱患的，比如不防水，不防爆，氣體隔絕不到位等，容易對生產(chǎn)安全構(gòu)成威脅，不能保證工業(yè)生產(chǎn)的安全。是專業(yè)生產(chǎn)防爆監(jiān)控攝像機的廠家，是華南地區(qū)其中一家獲得較高雙等級的防爆監(jiān)控**，所有的產(chǎn)品均達到EXDⅡCT6和DIPA20TAT6較高認證要求，只銷售通過國家認證的***的防爆攝像機。由于防爆攝像機一般是用于石油、化工、礦井、**、醫(yī)藥、油庫、輪船、鉆井平臺、加油站、花炮生產(chǎn)、糧食加工儲存等特殊場所，所以購買時，要考慮到產(chǎn)品的防爆等級，保證工業(yè)生產(chǎn)的安全。監(jiān)控終端所在建筑物內(nèi)應(yīng)有避雷系統(tǒng)、接地網(wǎng)及接地端子等配置。蘭州球形防爆攝像機廠家</p><p

style="text-indent:25px">防爆攝像機在什么檔次呢？清晰度。提到防爆攝像機性能，較先考慮到的是攝像機的清晰度。它指的是當(dāng)防爆攝像機去等間隔排列的黑白相間條紋時，在監(jiān)視器（應(yīng)比攝像機的分辨率高）上能夠看到的較多線數(shù)。當(dāng)超過這線數(shù)時，屏幕上就只能看到灰蒙蒙的一片而不能再辨出黑白相間的線條?，F(xiàn)在防爆攝像機的分辨率通常在480~700線之間，它是由攝像器件像素多少決定的，顯然攝像器件的像素越多，得到的圖像越清晰，反之也然。清晰度越高，說明攝像機檔次越高，反之越低。用戶可以根據(jù)自身的需要來選擇不同線數(shù)的防爆攝像機。蘭州球形防爆攝像機廠家</p></p><br
