摘　　要：智能组件是电力设备智能化的核心部件,但其工作环境特别复杂并存在多种电磁骚扰源,恶劣的电磁环境影响智能组件安全运行。为提高变电站智能组件的可靠性,解决其电磁兼容问题尤为重要。通过对气体绝缘变电站电磁骚扰源的特性及耦合途径分析,研究并联电容和铁氧体磁环对电磁骚扰的抑制作用并进行实验验证。实验结果表明该方法可有效抑制骚扰电压对智能组件端口的影响,为气体绝缘变电站智能组件的抗电磁兼容设计提供了依据。Intelligent assembly is the key to the intelligence of power equipment, but there are many factors including extremely complex environment, various sources of electromagnetic disturbance and poor electromagnetic environment hampering the running of the assembly. To improve the reliability of the intelligent assembly, it is particularly impor/ant to solve the problem of electromagnetic compatibility. Though the characteristics analysis of electromagnetic disturbance sources of gas insulated substations and its coupling paths, this paper studied the inhibiting effect of shunt capacitor and ferrite bead on electromagnetic disturbance and carried out tests for verification. Experimental results showed that those methods can effectively restrain the influence of disturbance voltage on intelligent assembly, providing the basis for the design of electromagnetic compatibility.
