摘　　要：某工业机器人进行电快速瞬变脉冲群(EFT/B)抗扰度试验时,系统发生故障、运行停止,随后进行的静电放电抗扰度(ESD)试验、浪涌(冲击)抗扰度试验也存在不能按照预定程序工作的情况。文章阐述了机器人系统的试验等级要求,简单介绍了ESD、EFT/B、浪涌(冲击)抗扰度测试标准及要求,根据以往经验结合试验和产品防护设计情况精确分析及定位了故障,并从内部走线、电源线滤波处理、壳体及内部器件接地、防护电路设计等方面给出具体的整改措施。整改后机器人系统顺利通过试验,整改措施有效。During the electrical fast transient/burst(EFT/B)immunity test of an industrial robot,the system malfunctioned and stopped running.The subsequent electrostatic discharge immunity(ESD)and surge(impact)immunity tests also failed to operate according to the predetermined procedures.The article elaborates on the testing level requirements of robot systems,briefly introduces the standards and requirements for ESD,EFT/B,surge(impact)immunity testing,and accurately analyzes and locates faults based on past experience combined with testing and product protection design.Specific rectification measures are provided from aspects such as internal wiring,power line filtering treatment,shell and internal device grounding,and protection circuit design.After the rectification,the robot system passed the test smoothly and the rectification measures were effective.
