style="text-indent:25px">防爆攝像機(jī)如何防水防霧：攝像機(jī)雨刷器的功能和汽車(chē)雨刷功能類似，許多監(jiān)控?cái)z像機(jī)都安裝了雨刷控制裝置。當(dāng)外部防護(hù)罩的視窗玻璃容易出現(xiàn)露水、霜和污垢，造成攝像機(jī)視線遮擋，雨刷器能夠及時(shí)清理，掃清礙"眼"的東西。從產(chǎn)品上來(lái)看，大多數(shù)支持云臺(tái)的球型監(jiān)控?cái)z像機(jī)支持雨刷功能，考慮到產(chǎn)品外形構(gòu)造，泵機(jī)安裝雨刷十分不方便。也有人說(shuō)，球形攝像機(jī)體積本來(lái)就很大，如果額外加上雨刷控制器，對(duì)其內(nèi)部空間負(fù)擔(dān)也不少。如果再將產(chǎn)品細(xì)分，紅外夜視監(jiān)控一體機(jī)安裝雨刷的比例很高，其很重要的一個(gè)原因就在于球機(jī)雙紅外光束溫度高，散熱較差，或許也有“不得以”的原因安裝小雨刷。當(dāng)然除了安裝雨刷外，還有一種方式是大多數(shù)廠商更為青睞的技術(shù)。相比較雨刷來(lái)說(shuō)，如果將雨刷"隱形"是否能夠減輕不少的負(fù)擔(dān)呢？隱形雨刷視窗玻璃具有排斥水、灰塵、雪花的功能。這是玻璃本身的質(zhì)地問(wèn)題，而并非依靠外部裝置進(jìn)行機(jī)械清掃。既解決了機(jī)械清掃過(guò)程，又不用在攝像機(jī)內(nèi)部安裝零部件，一舉多得何樂(lè)而不為呢。</p><p style="text-indent:25px">防爆攝像機(jī)的防爆原理：隔爆型結(jié)構(gòu)。電火花及電弧可以引燃危險(xiǎn)性混合物。由德國(guó)建立起來(lái)的間隙隔爆結(jié)構(gòu)，是防止電弧等引燃周?chē)ｋU(xiǎn)性混合物較可靠的方法。隔爆型結(jié)構(gòu)的電氣設(shè)備在危險(xiǎn)區(qū)域應(yīng)用極為普遍，它不光能防止危險(xiǎn)燃火的傳出，而且殼體又可承受一定的過(guò)壓。它具有一個(gè)足夠牢固的外殼，能經(jīng)受內(nèi)部危險(xiǎn)氣體混合物產(chǎn)生較大危險(xiǎn)壓力確保不變形或損壞，不產(chǎn)生較久變形，并具有一定結(jié)構(gòu)間隙以使噴射出來(lái)的燃燒生成物通過(guò)一定的法蘭長(zhǎng)度冷卻到低于外部危險(xiǎn)性混合物的自燃溫度。結(jié)構(gòu)間隙可以是平面結(jié)合面或圓筒結(jié)合面組成，還可以是曲路、螺紋或屏障式等結(jié)構(gòu)組成。除此之外。如微孔、網(wǎng)罩、疊片、充砂等結(jié)構(gòu)也屬于這種原理的防爆形式。用于煤礦井下的隔爆型電氣設(shè)備更要堅(jiān)固。用于I類采掘工作面的設(shè)備，外殼須采用鋼板或鑄鋼制成；I類非采掘工作面的設(shè)備，其外殼可用牌號(hào)不低于HT25-47灰鑄鐵制成；I類攜帶式設(shè)備和II類設(shè)備，外殼可用抗拉強(qiáng)度不低于117.6N/mm2（12kg/mm2）、含鎂量不大于0.5%（重量比）的輕合金制成。防爆攝像頭的防護(hù)：線纜雷電感應(yīng)電動(dòng)勢(shì)是一種高頻交變電壓，位置等效在線纜中間。</p><div

style="text-indent:25px">防爆攝像機(jī)：防爆攝像機(jī)能夠用在易燃易爆等危險(xiǎn)場(chǎng)所，如煤礦、石油廠、油庫(kù)、花炮廠等。防爆攝像機(jī)的攝像部分一般安裝在現(xiàn)場(chǎng),它包括攝像機(jī)、鏡頭、防爆護(hù)罩、支架和電動(dòng)云臺(tái)。它的作用是對(duì)監(jiān)視區(qū)域進(jìn)行攝像并將其轉(zhuǎn)換成電信號(hào)。防爆攝像機(jī)分為彩色和黑白兩種，一般黑白攝像機(jī)要比彩色的靈敏度高，比較適合用于光線不足的地方，彩色攝像機(jī)可以增加紅外效果以實(shí)現(xiàn)夜間監(jiān)控，光線暗時(shí)紅外燈自動(dòng)開(kāi)啟實(shí)現(xiàn)彩色和黑白轉(zhuǎn)換，如果使用的目的只是監(jiān)視景物的位置和移動(dòng)，可采用黑白攝像機(jī)；如果要分辨被攝像物體的細(xì)節(jié)，比如分辨衣服和景物的顏色，則采用彩色的比較好。防爆攝像機(jī)的規(guī)格可分為1/3〃、1/2〃和2/3〃等，安裝方式有固定和可轉(zhuǎn)動(dòng)的帶防爆云臺(tái)二種。防爆攝像機(jī)維護(hù)：對(duì)易吸塵部份每季度定期清理一次。東營(yíng)化工廠防爆攝像機(jī)生產(chǎn)廠家</p><p

style="text-indent:25px">阻礙防爆攝像機(jī)發(fā)展的原因：防爆攝像機(jī)有特定的使用環(huán)境。防爆攝像機(jī)一般不用于民用監(jiān)控系統(tǒng)，民用監(jiān)控系統(tǒng)一般的監(jiān)控?cái)z像機(jī)就可以滿足其需求，民用可以不用安裝防爆性能的攝像機(jī)，防爆攝像機(jī)一般用于環(huán)境比較特殊的產(chǎn)所，現(xiàn)在全國(guó)如：石油、化工、礦井、**、醫(yī)藥、油庫(kù)、輪船、鉆井平臺(tái)、加油站、花炮生產(chǎn)、糧食加工儲(chǔ)存等普遍應(yīng)用。這個(gè)特定的環(huán)境很大一部分限制了防爆攝像機(jī)的普遍推廣，在短期內(nèi)，防爆攝像機(jī)還是無(wú)法在普通產(chǎn)所大量應(yīng)用，需要一個(gè)大眾逐漸接受的過(guò)程，相信隨著民眾安防意識(shí)的不斷提高，防爆攝像機(jī)在不久的將來(lái)肯定可以大放異彩，走進(jìn)千家萬(wàn)戶。周邊配套設(shè)施不夠防爆。一臺(tái)再好的防爆攝像機(jī)，如果不配備防爆的后端設(shè)備或者專業(yè)的施工，那也發(fā)揮不出防爆的效果，例如采用的不是防爆云臺(tái)，又或者傳輸線材外露等都會(huì)存在安全隱患。所以要求工程商在購(gòu)買(mǎi)防爆攝像機(jī)時(shí)可以咨詢防爆廠家，在廠家處購(gòu)買(mǎi)一整套的防爆監(jiān)控設(shè)備，真正意義達(dá)到防爆的要求，發(fā)揮防爆攝像機(jī)的監(jiān)控及防爆的作用，而不是在造成事故或者在事故發(fā)生時(shí)“雪上加霜”。東營(yíng)室外防爆攝像頭廠家推薦</p></p><br
