| Abstract: | The technology for analyzing electromagnetic compatibility of aerospace electromagnetic relay is the foundation of research on high reliability of aerospace electric devices and their abilities of enduring poor environment. The fi nite element model of a certain type of aerospace electromagnetic relay is founded. The dynamic characteristics of relay are simulated according to GB/T 17626.29 (volt-age dips,short interruptions and voltage variations on DC input power port immunity tests) under the conducted interferences including voltage dips,short interruptions and voltage variations. Compared with the dynamic characteristics of relay without any interference,the effects of conducted interferences on aerospace electromagnetic relay are analyzed. The conclusion is of great value for the design of elec-tromagnetic relay and is the foundation of research on the electromagnetic compatibility of electric devices with relays. |
