style="text-indent:25px">防爆正壓柜的基本原理是在柜體封閉的情況下向柜內(nèi)通入空氣，使柜內(nèi)壓力大于環(huán)境壓力，進而防止危險氣體進入柜內(nèi)，使內(nèi)部的普通電氣元件能正常運行，但防爆正壓柜是全密封結(jié)構(gòu)，不易散熱。一、自然冷卻：這種方法是通過防爆正壓柜外壁自然散熱的方式進行工作，適用于正壓柜內(nèi)發(fā)熱較少，且外部環(huán)境溫度較低時采用，在正壓柜運行時，由于發(fā)熱而導(dǎo)致內(nèi)部溫度升高時，防爆正壓柜外壁的溫度也隨之升高，這時防爆正壓柜內(nèi)的熱量通過外壁向環(huán)境自然散出，而為了增加散熱效果，有時會在柜壁安裝散熱器。二、循環(huán)冷卻：循環(huán)冷卻一般是在自然冷卻不能滿足要求時采用的冷卻方式，其冷卻效果比自然冷卻效果好，這種方法通過設(shè)置柜內(nèi)外循環(huán)管道，使冷卻液在柜內(nèi)管道中被環(huán)境加熱后，流動到柜外管道中在散熱。</p><p style="text-indent:25px">防爆正壓柜進行調(diào)試，調(diào)試方法：關(guān)門調(diào)試：在配置好氣源后，接通電源。將進氣閥完全打開，按下“啟動”按鈕，進氣電磁閥打開，***30分鐘開始計時，進入換氣狀態(tài)。30分鐘后換氣結(jié)束，壓力值大于100Pa時，傳感器檢測正壓腔內(nèi)壓力值，并顯示在系統(tǒng)窗口中，進氣電磁閥關(guān)閉，通過電磁閥旁路節(jié)流閥給柜內(nèi)補氣，使壓力表值持續(xù)穩(wěn)定在200-300Pa之間，即整柜進入自動運行狀態(tài)，同時給正壓腔內(nèi)“接觸器”送電，主電路可送電進行正常工作，即調(diào)試完畢。防爆正壓柜現(xiàn)場必須有安全潔凈的氣源（壓縮空氣）。</p><div
