Shorting ring for an AC switching magnet
摘要:
An improved arrangement for connecting a shorting ring to the pole of an AC switching magnet in which the connecting straps of the shorting ring are formed such that axis of the center of gravity of the shorting ring lies on a line coincident with the line between the connecting points thereby assuring that the joint receives as little stress as possible.
