摘　　要：大型设备由于尺寸过大或供电要求过高无法进入实验室进行电磁兼容(EMC)性能测试,目前大型设备无明确的EMC现场测试标准要求。文章阐述了电磁兼容风险评估技术的分析机理及EMC风险评估理想模型,介绍了EMC风险评估要素识别、分析及EMC风险评价方法。借助电磁兼容风险评估技术可评价大型设备的EMC性能,也有助于大型设备现场测试中发现问题后,借助EMC风险评估技术发现EMC风险点,提出相应的风险减缓措施,以提升大型设备的EMC性能。It's not available to do the test in electromagnetic compatibility(EMC)laboratory for large size or high power supply equipments.Currently,there is no clear EMC in-situ testing standard requirement for large equipment.The article describes the analysis mechanism of EMC risk assessment technology and the ideal model of EMC risk assessment,and introduces the identification and analysis of EMC risk assessment elements and EMC risk evaluation methods.With the help of EMC risk assessment technology,the EMC performance of large equipment can be evaluated,and it can also help to find the EMC risk points with the help of EMC risk assessment technology after problems are found in in-situ test of large equipment,and put forward corresponding risk mitigation measures to improve the EMC performance of large equipment.
