X射线管组件在电磁兼容检测中必要性分析

Analysis of the Necessity of the X-ray Tube Components in Electromagnetic Compatibility Detection

本文针对目前医用X射线管组件在注册检测中对电磁兼容性(Electromagnetic Compatibility,EMC)评价时存在的矛盾进行讨论,分析了X射线管组件的EMC检测方法的意义和其必要性。本文设计了两组对比试验,将某型号的X射线管组件分别安装在两套不同的医用X射线系统内,按照YY 0505-2012的要求分别进行EMC测试。结果表明X射线管组件的发射特性和抗扰特性相比整个医用X射线系统的电磁兼容性可忽略不计。该研究指出X射线管组件的电磁兼容性可在医用X射线系统的电磁兼容特性中考虑,无需单独进行评价。

This paper discussed the conflict problems about electromagnetic compatibility(EMC)of medical X-ray tube components in the registration.The purpose of this research was to analyze the significance and necessity of EMC detection method of X-ray tube components.In this paper two comparative experiments were designed.We installed one type of X-ray tube assembly in two different medical X-ray systems and carried out EMC test according to YY0505-2012.The results showed that the emission characteristics and the anti-disturbance characteristics of the X-ray tube components were negligible compared with the electromagnetic compatibility of the whole medical X-ray system.We suggest that the electromagnetic compatibility of the X ray tube component should be considered in the electromagnetic compatibility of the X-ray system and there is no necessary to consider the electromagnetic compatibility of the X ray tube component alone.
