Immunity Of Communication Transceiver Equipment Under High Transient Conditions

With the continuous improvement of the voltage level, the application environment of communication transceiver equipment is becoming more and more serious, the electromagnetic compatibility problem caused by the electromagnetic disturbance is also more and more. Correct understanding the electromagnetic environment characteristics of communication transceiver equipment, is assurance for that the communication transceiver equipment can be applied in bad environment. As an important part of the system, the importance of that the communication transceiver equipment work or not is related to the safe and stable operation of the whole system. This thesis mainly research on the electromagnetic disturbance characteristics of communication transceiver equipment. Firstly this article introduces the finite integration theory and subdivision method of CST simulation software, Analyzes electromagnetic coupling mechanism of communication transceiver equipment in the space under the action electromagnetic field. Secondly research on radiation harassment model and transmission characteristics of communication transceiver equipment using CST and ADS simulation software, the article also obtained the distribution of the surface current flow in the model. The last part is the immunity test, the near field radiation immunity test in the laboratory, the open field radiation immunity test and bit error rate (BER) test in transient fields respectively, and using the method of shield and magnetic ring to suppress the transient disturbance.The modeling simulation and experimental results obtained in this paper can be used as the important reference for immunity design communication transceiver equipment and substation secondary system.
