Abstract
An improved annular resistor, suitable for use in a diesel electric locomotive dynamic braking system and similar applications comprising an assembly of similar arcuate segments. Each resistor segment has a supporting frame (11, 13) and a continuous resistance ribbon (53, 55, 57, 59) having a plurality of reflexed radial extensions between the two parts of the frame, electrically isolated from the frame. To allow expansion and contraction of the ribbon, U-shaped folds of the ribbon are mounted on pin supports (51). The pin supports are mounted to insulator blocks (27, 29, 37, 39), and are set so as to position the ribbons in a zig-zag or chevron pattern, in order to enhance cooling and improve the flow of air over the ribbon surfaces. Three terminals (67, 73, 75) are provided on each segment to allow part of the resistance of each segment to be removed from the circuit.
