| Abstract: | Relay's electromagnetic interference and its path were analyzed and the relay's complex domain equivalent circuit model was built by complex domain analysis method.The change rule of electrical contact's breaking current and voltage were calculated by the Matlab.The reason of producing the electric arc was discussed,which provides a basis for establishing relay's electromagnetic interference model to reveal the interference mechanism. |
| Keywords: | DC relay electromagnetic interference arc mathematical model |
