style="text-indent:25px">防爆攝像頭成本相對(duì)高。一臺(tái)防爆攝像頭的價(jià)格，要比同參數(shù)的普通攝像機(jī)高出一大截。國(guó)內(nèi)的工程商和用戶對(duì)這些高價(jià)位產(chǎn)品還沒有一個(gè)較高的接受度，還是需要時(shí)間去培養(yǎng)和轉(zhuǎn)變他們的消費(fèi)觀念和意識(shí)，這也較大制約了防爆攝像頭的普及。筆者了解到，近兩三年，不少之前做普通攝像機(jī)的廠家進(jìn)入到防爆攝像頭領(lǐng)域，其中大部分企業(yè)均按照防爆攝像頭的強(qiáng)制要求進(jìn)行產(chǎn)品管理，但也出現(xiàn)部分企業(yè)打著“防爆”的旗號(hào)，在不具備防爆設(shè)備的生產(chǎn)和檢測(cè)能力下，降低產(chǎn)品標(biāo)準(zhǔn)，從而以低成本沖擊市場(chǎng)。由于部分工程商或是甲方對(duì)防爆攝像頭了解不夠，加上部分廠家混淆概念的宣傳，使得一些工程采購(gòu)了不合規(guī)格的產(chǎn)品，嚴(yán)重的甚至造成了惡劣的后果，這無(wú)論是對(duì)防爆攝像頭廠家還是工程方，都是不可估量的損失，東營(yíng)室外防爆攝像機(jī)廠家推薦。根據(jù)防爆攝像頭所需要的成本，短時(shí)間內(nèi)無(wú)法解決高價(jià)格的問題，在購(gòu)買防爆攝像頭時(shí)固然要價(jià)格比三家，但是前提是該產(chǎn)品是通過安全認(rèn)證的產(chǎn)品，東營(yíng)室外防爆攝像機(jī)廠家推薦，東營(yíng)室外防爆攝像機(jī)廠家推薦，所以，要求工程商在購(gòu)買防爆產(chǎn)品的時(shí)候不能只看價(jià)格，購(gòu)買到假冒偽劣的安防產(chǎn)品，給工業(yè)生產(chǎn)帶來(lái)安全隱患。遇接觸不良點(diǎn)就產(chǎn)生火花、電弧或高溫，有可能環(huán)境中的性氣體。東營(yíng)室外防爆攝像機(jī)廠家推薦</p><div

style="text-indent:25px">如何選購(gòu)防爆攝像頭：防爆攝像頭的選擇較重要的是成套性。為了增強(qiáng)防爆攝像頭的環(huán)境適應(yīng)能力，通常還需要增加遮陽(yáng)罩、加熱器、過濾器、雨刮器、風(fēng)扇/半導(dǎo)體制冷器件等增值附件以確保設(shè)備的穩(wěn)定運(yùn)行和監(jiān)控畫面的清晰度。目前防爆攝像頭的國(guó)際主流方式是隔爆型：其特征在于將常規(guī)的普通攝像機(jī)放在特制的外殼內(nèi)，該外殼具有將殼內(nèi)電氣部件產(chǎn)生的火花和電弧與殼外性混合物隔離開的作用，并能承受進(jìn)入殼內(nèi)的性混合物被殼內(nèi)電氣設(shè)備的火花、電弧時(shí)所產(chǎn)生的壓力，而外殼不被破壞;同時(shí)能防止殼內(nèi)生成物向殼外性混合物傳爆，不會(huì)引起殼外性混合物燃燒和。東營(yíng)室外防爆攝像機(jī)廠家推薦總而言之，夏季全國(guó)大范圍雷雨都偏多，而且大部分的化工，發(fā)電廠，廠房等又多建在空曠的地方。</p><div

style="text-indent:25px">防爆攝像頭如何防雷？當(dāng)防爆攝像頭**架設(shè)時(shí)，為了防止避雷針及引下線上的暫態(tài)高電位，避雷針較好距防爆攝像頭3-4米的距離。另外，為防止電磁感應(yīng)，沿電線桿引上的防爆攝像頭電源線和信號(hào)線也應(yīng)穿在金屬管內(nèi)以達(dá)到屏蔽作用，屏蔽金屬管的兩端均應(yīng)接地。傳輸部分的線纜在線路架設(shè)上盡量采用埋敷方式。如果環(huán)境條件不許可時(shí)，也盡量采用較短間距架設(shè)方式以免耐壓性降低而導(dǎo)致感應(yīng)雷入侵。從直擊雷防護(hù)來(lái)說，監(jiān)控中心所在建筑物應(yīng)有防直擊雷的避雷針、避雷帶或避雷網(wǎng)。簡(jiǎn)單來(lái)說，監(jiān)控中心防雷應(yīng)從直擊雷防護(hù)、雷電波侵入、等電位連接和電涌保護(hù)多方面進(jìn)行?？偠灾?，夏季全國(guó)大范圍雷雨都偏多，而且大部分的化工，發(fā)電廠，廠房等又多建在空曠的地方。所以監(jiān)控中心和前端監(jiān)控采集攝像頭都要做好防雷措施，防雷擊是一個(gè)露天設(shè)備應(yīng)當(dāng)具備的基本措施，監(jiān)控系統(tǒng)要作為一個(gè)系統(tǒng)進(jìn)行防雷設(shè)計(jì)，包括傳輸模塊的防雷擊措施也要做好。這樣，我們才能在雷雨天氣來(lái)臨之際，不再擔(dān)心我們的攝像機(jī)受傷害！東營(yíng)室外防爆攝像機(jī)廠家推薦</p></p><br
