摘要: In the assembly two or more strips of resistance material are positioned edge-to-edge and fan-folded between the side members of a frame. The strips are supported at their loops by insulated fixtures and each has a terminal at each end. The strips are embossed or indented between loops so as to form longitudinally extending offsets spaced from each other across the strip. The depth of those offsets is controlled so that the clear space between the adjoining flights is just sufficient to admit a flat metal strip inserted between them crosswise with a portion projecting to form a tap. That tap can be positioned anywhere between parallel flights of the resistor ribbon after the assembly of the unit. A channel-shaped clip fits over the projecting tap and the edges of the adjoining flights of resistor ribbon and is welded to the tap and the flights.

摘要: A resistor grid for dynamic braking of diesel electric locomotives has a rigid frame comprising outer metal side pieces and metal dividers within the frame between which are positioned columns of fan-folded resistor ribbon. The dividers carry support plates having transverse aligned tabs along both sides fixed normal to the support plate, each tab having a notch in its inside edge, supported plates which slide in those slots longitudinally, the supported plates and the folds of the resistor ribbon carrying studs and bushings which interfit by movement normal to those plates.

摘要: A heat dissipating resistor grid has a rectangular or annular frame including side members carrying blocks or panels of insulating material having cavities in their inner surfaces. The resistor element is a zigzag strip formed from individual flat lengths of resistance material, each length having offset ends in opposite directions, adjoining offset ends forming a sandwich with a conductive support strip which extends beyond the offset end and terminates in projections which mate with the cavities in the insulating material. The support strip may extend into the space between the adjoining strips of resistance material forming a heat sink therein. The projecting ends of the support strip may be flat lengths, may be cut into tabs, may be formed into hollow cylinders in one piece with the support strip, may be solid cylindrical studs affixed to the support strip, or solid rod bent into U-shape with the base inside the offset ends. The insulating blocks may fit into cutouts in the frame and lock there by lateral movement.

摘要: A rigid frame supported resistor for dynamic braking of electric and diesel-electric locomotives has certain of the frame elements cushioned or insulated from each other and the resistance ribbon insulated and cushioned from the frame. Organic insulating material in molded or sheet form, preferably a copolymer, such as a polyester resin, protected by a metal heat shield, may be used for structural frame members, or for cushioning and insulating metal structural frame members. The organic insulating resistant is supplemented by ceramic insulating material in locations subject to high heat.

摘要: A resistor grid for diesel electric locomotives and the like has a rigid frame comprising outer metal side pieces and one or more pairs of inner metal side pieces spaced from each other, and columns of resistor ribbon fan-folded between each outer and outermost inner side piece, and between certain inner side pieces. Supporting means interengaging each fold of the ribbons are insulated from and carried on each side by a metal strip which rides on its adjoining side piece so as to accommodate expansion of the resistor ribbon. The ribbon is indented between folds to stiffen it and increase its span and may by provided with a support rod centered between its side pieces. The resistor grid is preferably positioned in forced air cooled resistor banks face-to-face with conventional narrow span grids, and improves the cooling of such conventional banks.

摘要: A resistor grid assembly has a continuous resistor weave with a plurality of generally parallel, plate-like electrical elements. U-shaped bends join two adjacent elements at adjacent ends. The U-shaped bends are located in a bottom group and a top group. There is a top electrical insulating member adjacent the U-shaped bends in the top group and spaced from the U-shaped bends. There is a bottom electrical insulating member adjacent the U-shaped bends in the bottom group. Stop U-shaped pins having a pair of legs with a pair of shoulders are supported by the bottom electrical insulating member. The legs of each stop U-shaped pin extends into a pair of holes in the bottom group of U-shaped pins and rest upon the shoulders which are spaced from the insulator. Wire U-shaped pins are supported by the top electrical insulating member. The wire U-shaped pins have legs inserted into holes in the U-shaped bends in the top group. The U-shaped bends in the top group are spaced from the top insulator. When the resistor elements expand due to heat, the U-shaped bends in the top group move on the legs of the wire U-shaped pin toward the top insulating member. Expansion is controlled in a direction toward the top insulating member and the resistor U-shaped bend slides on the wire U-shaped pin.
