In order to ensure the electronics of radial X-ray camera (RXC) system can work normally under the complicated electromagnetic environment of Tokamak system, simulation and analysis of the static magnetic distribution is done in this paper. The electromagnetic shielding box is designed and shielding effort was validated through simulation with software Maxwell. The shielding box designed can reduce the static magnetic flux density from 230 mT to less than 5 mT, meeting the requirements of anti-electromagnetic interference ability of electronics.

径向X射线相机电子设备的电磁屏蔽箱设计

为了保证径向X射线相机（RXC）系统的电子器件在托卡马克系统复杂的电磁环境下能正常工作，本文对静磁分布进行了仿真分析。设计了电磁屏蔽盒，并通过 Maxwell 软件模拟验证了屏蔽效果。设计的屏蔽盒可将静磁通密度从230mT降低到5mT以下，满足电子产品抗电磁干扰能力的要求。
