防爆标志和防爆管件规格尺寸防爆标志举例 Explosive mark exemplify


  1. 如电气设备为ⅡB类隔爆型T3组,标志为ExdⅡBT3。


  2. 如电气设备为Ⅱ类增安型,温度组别为T2组,标志为ExeⅡT2。


  3. 如电气设备采用一种以上的复合型式,则先标出主体防爆型式,后标出其它防爆型式,如主体采用增安型内装ⅡC类隔爆部件,温度组别为T4,标志为ExedⅡCT4。如果主要部件采用隔爆型ⅡB类,T4组,其余部件为增安型,则防爆标志为ExdeⅡBT4。


  4. DIP A20 TA,T4,DIP表示粉尘防爆,A20表示可使用于20区的A型设备,TA,T4表示设备的温度组别为T4(135℃)。


  1. Class ⅡB,group T3 falmeproof explosive electric equipment, mark "ExdⅡBT3".


  2. Class Ⅱ,group T2 increasing safety explosive electric equipment, mark "ExeⅡT2".


  3. It adopts multiple type, First mark main explosive proof type. Then mark other explosive-proof type.The main body adopt increasing safety and built-in classⅡC isolative explosion parts,temperature T4,mark "EexdⅡCT4",if main part adopts isolative explosive ⅡB T4,other adopt increasing safety, then it marks " ExdeⅡBT4".


  4. DIP A20 TA,T4, DIP means dustignition explosion-proof ,A20 means type A explosive-proof equipment and used for Zone 20,TA,T4 means temperature T4 (135℃)
