轻质油品在管线输送中产生大量静电,由此造成的燃爆事故时有发生。 要消除这些静电,光靠采取接地、控制流速、规定静置时间等常规措施是远远不够的。因为静电接地只能将金属外壁上的静电导走,抑制电荷不能按指数规律增长。由于油品均属高绝缘液体,所以对于油内电荷的泄漏需要一 Light oil in the pipeline transportation in a large amount of static electricity, resulting in the blasting accidents have occurred. To eliminate these static electricity, relying solely on the ground to control the flow rate, the provisions of the rest time and other conventional measures is not enough. Because the electrostatic grounding can only be conducted on the metal outer wall of the static lead, inhibit the charge can not grow exponentially. As the oil is a high insulating liquid, it needs one for the leakage of the charge inside the oil
