Bouncing of Keeping Relay due to Permanent Magnet

초록

The electrical relay in the an essential part of the smart grid, Electrical Vehicle(EV) and LED lightning system. For these reasons, research of electrical relay is actively underway. In this paper, analyze of the relationship between the bouncing of latching relay and magnetic flux of permanent magnet. And find the value of the magnetic flux that occurs to minimize the bouncing of the contacts. However, the bounce will increase again with increasing more and more magnetic flux. The bouncing number of latching relay is less than expected the armature relay for present results. In addition, it is necessary to proceed with the bounce experiment of armature relay.
