ELECTRICAL CURRENT COLLECTING DEVICES

摘要

An electrical current-collecting device for passing high currents between relatively fast moving conductors is in the form of a circular brush having projecting conducting bristles and mounted on a spindle about which it is rotated with the bristles in contact with a moving conductor so that the relative speed between the conductor and the bristles is relatively small and good electrical conduction is achieved. The current may then be passed on to a second, normally stationary, conductor through the spindle made of conducting material and much smaller in diameter than the brush so that contact with the second conductor can be made at relatively low speed.
