從而形成一個(gè)危險(xiǎn)區(qū)間。如果雷電擊穿二次密封的材料，則很有可能點(diǎn)燃一次密封與二次密封之間的油氣混合物，而發(fā)生雷擊起火事故。另外，機(jī)械結(jié)構(gòu)整個(gè)結(jié)構(gòu)為金屬制品，與氣柜壁又未形成絕緣保護(hù)，在油氣柜運(yùn)行時(shí)機(jī)械支撐的環(huán)形密封圈與不規(guī)則的氣柜壁時(shí)而存在間隙，時(shí)而處于閉合狀態(tài)，當(dāng)其存在間隙時(shí)，極易在雷雨放電時(shí)形成放電火花而引發(fā)雷擊火災(zāi)事故。因此對(duì)于機(jī)械密封來(lái)說(shuō)，其本身存在的缺陷極易導(dǎo)致油氣混合物和電火花的形成。
