摘　　要：该文围绕一款立式医用盆腔医疗仪在电磁兼容测试的静电放电项目中出现的三个问题,从静电放电机理及等效模型入手,详细分析了问题的成因,根据上述原因提供了金属杆接地处理、电磁场屏蔽保护、电源的TVS防护等三个整改措施,并详细解释了各措施的静电抑制原理,最终通过测试验证方案可行.This article focuses on the three problems about the EMC test of a vertical medical pelvic cavity Instrument.The causes of these problems are analysed from the aspect of theory and model of electrostatic discharge machine. Ac-cording to the above reasons,grounding of metal rod,shielding of electromagnetic field and TVS protection for electricsource are taken in this equipment,and explains the measures of electrostatic suppression principle in detail,finallythrough the verification test scheme is feasible.
