style="text-indent:25px">防爆監(jiān)控攝像機(jī)使用中的問題：1、監(jiān)控設(shè)備維護(hù)應(yīng)注意以下幾點(diǎn)：（1）對每個防爆攝像機(jī)所供電源的插座要經(jīng)常檢查，防止插頭脫落。（2）保證對每個防爆監(jiān)控攝像機(jī)和監(jiān)控中心的供電電壓較恒定。（3）對低矮位置的防爆攝像機(jī)盡量設(shè)有明顯標(biāo)志，提醒非監(jiān)控管理人觸碰。（4）對監(jiān)控中心的監(jiān)控控制設(shè)備派專人管，要求非監(jiān)控人員禁止操作。（5）監(jiān)控中心在每晚無人的情況下一定要對監(jiān)控設(shè)備斷電。（6）對監(jiān)控設(shè)備經(jīng)常擦試保養(yǎng)。2、新安裝的防爆云臺使用后不久就運(yùn)轉(zhuǎn)不靈或根本不轉(zhuǎn)動。這種情況的出現(xiàn)除云去產(chǎn)品質(zhì)量的因素外，一般是以下三種原因造成的：（1）只允許將防爆監(jiān)控攝像機(jī)正裝的防爆云臺，在使用時采用了吊裝的方式。在這種情況下，吊裝方式導(dǎo)致防爆云臺運(yùn)轉(zhuǎn)負(fù)荷加大，故使用不久就會導(dǎo)致防爆云臺的轉(zhuǎn)動機(jī)構(gòu)損壞，甚至燒毀電機(jī)。（2）防爆監(jiān)控攝像機(jī)及其防護(hù)罩等總重量超過防爆云臺的承重。特別是室外使用的防爆云臺，往往防護(hù)罩的重量過大，常會出現(xiàn)防爆云臺轉(zhuǎn)不動（特別是垂直方向轉(zhuǎn)不動）的問題。（3）室外防爆云臺因環(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">防爆攝像頭的鏡頭：鏡頭是攝像機(jī)用來抓取畫面的工具，不同的鏡頭得到的畫面大小和效果也不一樣。常用的鏡頭種類包括：手動/自動光圈定焦鏡頭和自動光圈變焦鏡頭兩種。定焦鏡頭分為標(biāo)準(zhǔn)鏡頭和廣角鏡頭兩種。定焦鏡頭的適用范圍為：1.手動光圈鏡頭：所需監(jiān)視的環(huán)境照度變化不大，如室內(nèi)。2.自動光圈鏡頭：所需監(jiān)視的環(huán)境照度變化大，如室外。3.廣角鏡頭：監(jiān)視的角度較寬，距離較近。4.標(biāo)準(zhǔn)鏡頭：監(jiān)視的角度和距離適中。變焦鏡頭分為10倍、6倍和2倍變焦鏡頭，另一種分法是：手動變焦和電動變焦(電動光圈和自動光圈)兩種。變焦鏡頭在規(guī)則上可以劃分為：1/3〃、1/2〃和1〃等。選擇變焦鏡頭的原則是：鏡頭的規(guī)格不應(yīng)小于攝像機(jī)的規(guī)格，也就是說1/2〃的鏡頭可以與1/3〃的攝像機(jī)一起使用，但是1/3〃的鏡頭就不能夠在1/2〃的攝像機(jī)上使用。防爆攝像頭的防護(hù)：前端設(shè)備的防雷。</p><div

style="text-indent:25px">防爆攝像頭的防護(hù)：做好防爆監(jiān)控設(shè)備的防水防潮工作。在防爆視頻監(jiān)控系統(tǒng)應(yīng)用中，防爆攝像頭分布在各種前端環(huán)境，其中室外占據(jù)著較大的比例。由于受各種天氣因素的干擾，室外攝像頭往往要具有紅外夜視、防水、防霧、防雨雪等等功能。遇到暴雨時，監(jiān)控設(shè)備事先做好防御顯得格外重要。防爆攝像機(jī)工作時溫度變化大，容易出現(xiàn)水霧，尤其在雨水較多的季節(jié)，霧、霜的形成是由于空氣中的溫度濕度飽和，水蒸氣遇冷凝結(jié)而成，因低溫環(huán)境的強(qiáng)、弱分別凝結(jié)成霜和霧。攝像頭在濕度大和灰塵多的環(huán)境下工作，防護(hù)罩的視窗玻璃容易出現(xiàn)污垢，造成進(jìn)入攝像機(jī)的光線被遮擋，導(dǎo)致鏡頭模糊無法拍清物體，直接影響視頻采集效果。防爆攝像機(jī)維護(hù)：每月定期對防爆監(jiān)控系統(tǒng)和設(shè)備進(jìn)行優(yōu)化。煙臺戶外防爆監(jiān)控攝像機(jī)哪家好</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性混合物。由德國建立起來的間隙隔爆結(jié)構(gòu)，是防止電弧等引燃周圍危險性混合物較可靠的方法。隔爆型結(jié)構(gòu)的電氣設(shè)備在危險區(qū)域應(yīng)用極為普遍，它不光能防止危險燃火的傳出，而且殼體又可承受一定的過壓。它具有一個足夠牢固的外殼，能經(jīng)受內(nèi)部危險氣體混合物產(chǎn)生較大危險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)間隙以使噴射出來的燃燒生成物通過一定的法蘭長度冷卻到低于外部危險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。咸陽專業(yè)防爆攝像機(jī)生產(chǎn)廠家</p></p><br
