上述密封罩2具体的设置方式为：密封座1上开设有与密封罩相匹配的油槽11，密封罩2的底端密封式卡合固定于油槽内。密封罩2密封卡合固定的方式为：油槽11相对的两内侧壁上均粘接固定有一呈双层复合结构的胶条13，该胶条包括贴合于油槽内侧壁下半部的密封部和贴合于油槽内侧壁上半部的清理部，该密封部和清理部一体成型。其中清理部的顶端与所述油槽的顶端入口齐平，且该清理部的顶端沿水平方向延伸形成遮掩部，该遮掩部能够遮掩覆盖所述油槽的槽口。通过在油槽的顶端入口处加装一周含密封部、清理部和遮掩部的胶条，该胶条采用硅胶或橡胶等具有弹性的材质制成，遮掩部利用自身弹性形成单向槽口，没有外力挤压时，遮掩部可以遮掩覆盖住油槽槽口，避免灰尘或杂志落入油槽内；在安装密封罩时，利用材质的弹性形变挤压在油槽两侧面的密封部，一方面可以起到密封效果，另一方面还可在打开密封罩时对油槽内的密封油起到防护效果；位于上端的清理部可以在密封罩2插入或者取出时清理掉密封罩2表面附带的灰尘杂质或密封油渍，增强使用稳定性。
油槽11的内部灌注有密封油，密封罩的底端卡合固设于油槽内两胶条的清理胶条之间，密封油的使用能够使密封罩2的密封效果更好更强。此外，密封罩2的周壁外侧上形成有充气口21。
上述箱体3具体的设置方式为：密封座1上位于油槽的内侧处固设有与箱体相匹配的安装座12，箱体3的底端卡合固定于安装座上。此外，箱体3的内部设有供填充砂粒材料的隔层31，一旦箱体内发生在规定使用条件下产生电弧、发生火焰、外壳壁或砂粒材料表面过热的情况时，隔层能够保证不会点燃周围的爆炸性混合物。
上述箱体3的顶端上固设有一灭火装置4。该灭火装置包括一用于容纳灭火材料且位于箱体顶面的灭火容器41，箱体3的顶面上开设有与灭火容器41的内部相连通的流通管道42，此外箱体3的顶面上还开设有连通灭火容器41和流通管道42的连通孔301。在本具体实施例中，流通管道42和连通孔301均设于箱体3的顶壁的内部，其中连通孔301开设于靠近箱体顶壁的上表面处， 其中流通管道42开设于靠近箱体顶壁的下表面处。此外，流通管道42位于箱体3内部的一端上设有若干个均匀分布的喷头43，具体的，若干喷头43形成于箱体3的顶面内侧上，且该若干喷头均与流通管道连通。这样，灭火材料从灭火容器内部依次经由连通孔301和流通管道42后进入喷头43，由喷头喷洒至箱体3的内部。

本实用新型的工作原理是：
使用时，先在油槽11内注入密封油，然后将箱体3安装到密封座1的安装座12上，完成箱体3的安装固定；再将灭火装置4的灭火容器41安装到箱体3的上方，结合箱体3内部顶端安装的流通管道42和喷头43，完成灭火装置4的安装固定；最后将密封罩2卡合置入密封座1的油槽11内，完成防爆型电气控制箱的安装固定。在箱体3内装有环境监测装置，当检测到箱体3内的环境异常时，如温度、湿度和气体浓度等发生变化时，可以通过报警器警示工作人员。工作人员打开预处理装置5，利用真空泵51的抽气管52对箱体3进行抽真空操作，利用出气管53将抽出的空气排出，使箱体3内形成真空环境，成为一个不易爆炸的箱体环境，此时再打开密封罩2对箱体3进行检修；若发现短路火花或其他异常情况，可以打开灭火装置4，将灭火容器41内的灭火材料通过流通管道42从喷头43喷出，喷洒在箱体3内的每个角落，利用灭火容器41内的灭火材料通过喷头43喷出对箱体3内的环境进行改善，避免发生爆炸或火灾，增强防爆箱体3的整体安全性。
以上所述的，仅为本实用新型较佳的具体实施方式，但本实用新型的保护 范围并不局限于此，任何熟悉本技术领域的技术人员在本实用新型揭露的技术范围内，根据本实用新型的技术方案及其实用新型构思加以等同替换或改变，都应涵盖在本实用新型的保护范围之内。
