摘　　要：针对铝粉抽尘管道存在接地不良、静电累积、瞬时放电可能引起爆炸的安全隐患问题,提出在铝粉抽尘管道采用电压扫描静电法进行沉积粉尘静电实时测试技术,并对其测量原理和测量关键影响因素进行分析、研究。研究表明,采用电压扫描静电检测技术能够实时监测抽尘管道静电电位,测试误差<10%,能够起到铝粉抽尘管道携带静电的安全警示作用。In view of the hidden danger of explosion caused by poor grounding,static accumulation and instantaneous discharge in aluminum dust extraction pipeline,a real-time electrostatic testing technology for deposited dust by voltage scanning electrostatic method in aluminum dust extraction pipeline was proposed,and its measurement principle and key influencing factors were analyzed and studied.The results showed that the electrostatic potential of dust extraction pipeline can be monitored in real time by using voltage scanning electrostatic detection technology,and the test error is less than 10%,which can serve as a safety warning for the static electricity carried by aluminum dust extraction pipeline.
