style="text-indent:25px">在增安型防爆正壓柜中，可能與可燃性氣體-空氣混合物接觸的零部件的極高發(fā)熱溫度，是決定防爆正壓柜防爆安全性能的一個重要因素。載流零部件，尤其是一些功率元件，例如繞組、電熱元件，是防爆正壓柜的發(fā)熱源，內蒙古防爆正壓柜供應，內蒙古防爆正壓柜供應。極高發(fā)熱溫度不應該超過增安型防爆正壓柜的極限溫度，內蒙古防爆正壓柜供應。所謂極限溢度，是指防爆正壓柜的極高允許溫度，它是防爆正壓柜溢度組別確定的溫度和所用材料達到熱穩(wěn)定時的穩(wěn)定溫度中較低的那個溫度。極限溫度是保證增安型防爆正壓柜防爆安全性能的一個“門檻”。防爆正壓柜可作為**信號處理系統及**控制系統。內蒙古防爆正壓柜供應</p><div

style="text-indent:25px">防爆正壓柜的門和蓋子：防爆正壓柜的門和蓋子要同電氣回路進行聯鎖，當門或蓋子開啟時時，應該自動切斷防爆正壓柜中未防爆處理的電氣元件的電源；當門或蓋子沒有可靠關閉之前，不能重新對這些沒有進行防爆處理的元件供電。防爆正壓柜的進氣口和排氣口：防爆正壓柜上的保護氣體的進氣和排氣口的位置，根據保護性氣體的比重來設置。當使用的保護性氣體的比重比空氣大的時候，進氣口開在防爆正壓柜的上部，排氣口開在防爆正壓柜的下部；當保護氣體比空氣輕時，進氣口開在防爆正壓柜的下部，排氣口開設在防爆正壓柜的上部。防爆正壓柜的進氣口和排氣口都應開在對立處，這樣布局便于氣體的流動和吹掃換氣。內蒙古防爆正壓柜供應防爆正壓柜的正壓外殼應該具有足夠的機械強度。</p><div

style="text-indent:25px">這里按照新的防爆正壓柜焊接分類，結合防爆電氣設備的應用，簡單地介紹幾種經常使用的具有表示性的方法；其他的不予考慮。　　熔融結合焊：　　熔融結合焊是一種防爆正壓柜以熔化方式結合在一起的焊接方法。由于使防爆正壓柜熔化的加熱方式不同，這種焊接方法又分為電弧加熱焊和非電弧加熱焊；顧名思義，電弧加熱焊就是用電弧產生的熱來加熱進行焊接的，而非電弧加熱焊不是用電弧產生的熱而是用非電弧熱，例如燃氣熱、電阻熱等，來加熱進行焊接的。</p><p style="text-indent:25px">防爆正壓柜用正壓吹掃控制系統的功能及防爆正壓柜柜體的結構特點： 1.它的防爆原理主要是采用介質隔離點燃源的防爆措施以及形成正壓保護從而達到電器防爆的目的; 2.結構上采用上可按用戶要求分別定制成箱式、琴臺式和柜式結構，柜式又分為上下結構和左右結構。箱式一般采用鋼板焊接而成，表面噴塑，前開門操作;琴臺式和柜式其柜架采用標準型材焊接，表面噴塑，對其各接合面都經過了特殊的密封處理;前開門操作后開門維修。鋼板材料一般選用GB710-88冷軋鋼板. 3.按進氣方式分為持續(xù)吹掃型和泄露補償型。持續(xù)吹掃型為不間斷連續(xù)供氣，正壓腔內裝元件的工作熱量可隨氣路帶走，具有很好的散熱功能;泄露補償型為間斷性供氣，正壓腔有良好的密封性，耗氣量小;防爆正壓柜可多臺并柜。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

style="text-indent:25px">防爆正壓柜在使用過程中，若壓力降低，當壓力值低于100Pa時，防爆紅燈會報警，進入欠壓報警狀態(tài)，當進氣故障未排除，柜內壓力低于50Pa時，自控系統將切斷正壓腔主電源;系統將一直處于欠壓報警狀態(tài)(可通過按下“消音”按鍵解除);此為低壓保護及電氣聯鎖過程。防爆正壓柜有柜體和正壓吹掃控制系統裝置兩部分組成，防爆正壓柜氣源由正壓吹掃控制裝置進入柜體吹掃并達到安全起亞要求，當低壓報警時，正壓吹掃控制裝置會輸出信號報警，必要時會切斷正壓柜電源。當正壓腔壓力高于400Pa時，限壓閥打開，經過一段時間，正壓腔的內部氣壓逐漸下降，使柜內壓力限制在正常壓力范圍之內，閥門關閉，此過程為高壓限制保護過程。防爆正壓柜的正壓外殼采用鋼板（如Q235鋼板），或者不銹鋼材料（如304不銹鋼）。內蒙古防爆正壓柜供應</p><p
