Abstract
The utility model relates to a braking resistor strip for a locomotive braking resistor device. The braking resistor strip comprises multiple strip-shaped resistor sheets; the strip-shaped resistor sheets are arranged at equal intervals, and the end parts of the strip-shaped resistor sheets are sequentially connected in series through welding; the strip-shaped resistor sheets are S-shaped; and the middle parts of the strip-shaped resistor sheets are provided with mounting grooves which are in the shape of a Chinese character 'tu', thus facilitating the installation. When the resistor strip in the utility model is in use, each resistor strip is arranged in the discharge return circuit of the braking resistor device; and during use, the strip-shaped resistor sheets connected in series constitute a resistor grid which is placed in an insulation frame, multiple insulation frames constitute a resistor unit of the locomotive braking resistor device, and a fan is arranged at the resistor unit side.
Description
Technical field
The utility model relates to a kind of locomotive brake resistance device with the brake resistive band.
Background technology
On the trunk railway diesel-electric locomotive, all adopt the resistance braking device, because locomotive is to be power with the diesel engine, be connected with main generator through elastic coupling, the electricity that sends is that locomotive wheel provides electrical source of power to last traction electric machine through electrical control cubicles; Traction electric machine is passed to wheel to last driven gear drive wheels train operation through driving gear, and whole process is the journey that turns over of mechanical energy--electric energy--mechanical energy.Locomotive is when braking; Because of the rotor speed of traction electric machine is higher than stator rotating magnetic field rotating speed; Traction electric machine becomes electromagnetic power output state (that is: generator situation) by the electromagnetic power input state, will be the braking force of train to the locomotive power of having the opposite effect, and this part alternating current is after the rectification of thermal change device; Directly add to braking resistor and convert heat energy to, the cooling air that is blown into through blower fan is taken away and is consumed.This is the conversion process of a mechanical energy--electric energy--heat energy.
Electric resistance band in the braking resistor of the prior art, installation and maintenance inconvenience and maintenance cost are higher.How a kind of resistive band simple in structure, convenient for installation and maintenance is provided, and is the technical problem that this area will solve.
The utility model content
The technical problem that the utility model will solve provides a kind of locomotive brake resistance device simple in structure, convenient for installation and maintenance and with low cost with the brake resistive band.
In order to solve the problems of the technologies described above, the utility model provides a kind of locomotive brake resistance device with the brake resistive band, comprising: a plurality of ribbon resistance sheets, equidistant arrangement of each ribbon resistance sheet and end are through welding polyphone successively.
Said ribbon resistance sheet is snakelike, and the central authorities of this ribbon resistance sheet are provided with the mounting groove of convex shape, installs with convenient.
The technique scheme of the utility model is compared prior art and is had the following advantages: the resistive band in the utility model in use, each resistive band is located in the discharge loop in the braking resistor.Resistive band is processed by the metal exothermic material, and is easy to process, with low cost.Each ribbon resistance sheet is equidistantly arranged and contact through welding successively in the end, to constitute an electric heating group.Resistive band in the utility model in use, each resistive band is located in the discharge loop in the braking resistor.During use, each ribbon resistance sheet of polyphone constitutes a resistance grid and places an insulation frame, and a plurality of insulation frames constitute the resistance unit of locomotive brake resistance device, and the side of resistance unit is provided with blower fan.
Description of drawings
For the content that makes the utility model is more clearly understood, below basis specific embodiment and combine accompanying drawing, the utility model is done further detailed explanation, wherein
Fig. 1 is the structural representation of the locomotive brake resistance device of the utility model with the brake resistive band.
Embodiment
See Fig. 1, the locomotive brake resistance device of present embodiment comprises with the brake resistive band: a plurality of ribbon resistance sheets 1, each ribbon resistance sheet are equidistantly arranged and contact through welding successively in the end.
Said ribbon resistance sheet 1 is snakelike, and the central authorities of this ribbon resistance sheet 1 are provided with the mounting groove of convex shape, installs with convenient.
Obviously, the foregoing description only be for explain clearly that the utility model does for example, and be not to be qualification to the execution mode of the utility model.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all execution modes.And conspicuous variation that these spirit that belong to the utility model are extended out or change still are among the protection range of the utility model.
