摘　　要：为解决管输油流因静电带电可能引发的静电安全问题,提出了管输油流电荷密度监测与联锁控制系统的设计思路与实现方案。研究了测量输油管道内中心电位得到油流静电电荷密度的检测原理,基于杆球传感器设计开发了油品电荷密度表;利用该油品电荷密度表,结合溢油静电保护控制器,组成管输油流静电监测与联锁控制系统,并在国内首次开展了油库装车过程油流静电电荷密度监测与联锁控制现场试验。现场试验结果表明:测试数据很好地反映了油罐车装油时的静电起电情况,该技术有效提高了油流静电监测能力,可基于此技术控制输油过程,确保油品输送安全。When oil is transported through pipelines, electrostatic safety accidents may be caused by the static electricity of oil flow in pipelines. In order to solve this problem, the design idea and implementation scheme of pipeline oil-flow charge density monitoring and interlocking control system were proposed. The principle of detecting oil-flow electrostatic charge density by measuring the central potential in the oil pipeline was studied. Oil product charge density gauge was designed and developed on the basis of rod ball sensor. This gauge, together with oil-spill electrostatic protector, constitutes the pipeline oil flow electrostatic monitoring and interlocking control system. And this system was, for the first time, used on site for the monitoring and interlocking control of oil-flow electrostatic charge density in the process of oil loading at an oil depot in China. It is shown that testing data can reflect the static electrification situations while the oil is loaded onto tank trucks and this technology improves the oil-flow electrostatic monitoring capacity effectively. If this technology is used for oil transportation process control, the safety of oil production transportation can be guaranteed.
