1.?它的防爆原理主要是采用介質(zhì)隔離點(diǎn)燃源的防爆措施從而達(dá)到電器防爆的目的；　　2.?結(jié)構(gòu)上采用上可按用戶要求分別定制成箱式、琴臺(tái)式和柜式結(jié)構(gòu)，柜式又分為上下結(jié)構(gòu)和左右結(jié)構(gòu)。箱式一般采用鋼板焊接而成，表面噴塑，前開門操作；琴臺(tái)式和柜式其柜架采用標(biāo)準(zhǔn)型材焊接，表面噴塑，對(duì)其各接合面都經(jīng)過(guò)了特殊的密封處理；前開門操作后開門維修。鋼板材料一般選用GB710-88冷軋鋼板，也可根據(jù)用戶要求選用GB3280-84不銹鋼材質(zhì)；主柜為正壓室，防護(hù)等級(jí)為IP54，?副柜為輔助室，安裝正壓控制系統(tǒng)，保護(hù)等級(jí)為IP31；　　3.?按進(jìn)氣方式分為通風(fēng)型和補(bǔ)償型。通風(fēng)型為不間斷連續(xù)供氣，正壓腔內(nèi)裝元件的工作熱量可隨氣路帶走，具有很好的散熱功能；補(bǔ)償型為間斷性供氣，正壓腔有良好的密封性，耗氣量??；</p><p

一、注意經(jīng)常檢查密封圈的老化情況，發(fā)現(xiàn)老化時(shí)應(yīng)立即更換。二、防爆自控箱的隔爆結(jié)合面須防銹處理，每次檢修或打開箱蓋，須重涂204-1防銹油。三、每次更換面板元件，或打開后蓋重新蓋上時(shí)，應(yīng)檢查其密封性。防爆正壓柜注意事項(xiàng) 由于本柜內(nèi)裝觸摸屏等元器件，因此，請(qǐng)?jiān)诎踩珔^(qū)內(nèi)安裝相應(yīng)程序，嚴(yán)禁在防爆區(qū)內(nèi)打開后蓋帶電操作！防爆正壓柜當(dāng)氣壓低于50Pa時(shí)，自控系統(tǒng)自動(dòng)發(fā)出報(bào)警以及輸出報(bào)警信號(hào)。</p><div
