Description
Technical field
The utility model relates to a kind of locomotive brake apparatus, specifically is a kind of locomotive brake resistance device.
Background technology
All adopt the resistance braking device on the trunk railway diesel-electric locomotive, because locomotive is to be power with the diesel engine, be connected with main generator through elastic coupling, the electricity that sends provides electrical source of power for locomotive wheel 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, to to the locomotive power of having the opposite effect the braking force of train, 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.
Braking resistor of the prior art: the one,, resistance grid is to be formed by the continuous bending of single resistive band, the big and difficult accurately control of its creepage distance; Heating is prone to the belt distortion after resistive band load, influences distance between commutator segments, causes the resistance over-heated fault; The 2nd,, cold wind, is taken away heat to the resistance grid by ventilating duct median septum stream with uniform distribution, but the wind flow distribution still has the dead angle, causes temperature contrast on the resistance grid each point, influences useful life.The 3rd,, need the big disintegration of whole braking resistor rear is replaceable during the resistance grid maintenance, safeguard that inconvenience and maintenance cost are higher.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of simple in structure, be suitable for accurately controlling creepage distance, easy to maintenance and locomotive brake resistance device that maintenance cost is cheap.
For solving the problems of the technologies described above, the utility model provides a kind of locomotive brake resistance device, comprise: the resistance unit of the blower fan of upper and lower settings, air ducting and a plurality of stacked settings successively, described resistance unit comprise the insulation frame and are located at resistance grid in this insulation frame; The resistance grid is made of through the welding ribbon resistance sheet of polyphone successively equidistant arrangement and end.
Further, described insulation frame is made of upper plate, lower plate, dividing plate and biside plate.Upper plate, lower plate and the dividing plate of insulation frame is provided with the installing hole of the connecting portion that is used for ccontaining each ribbon resistance sheet of row's spaced set, to fix the creepage distance between each ribbon resistance sheet and the accurate control adjacent resistor sheet.
Further, connect with conducting copper between the described resistance grid.
Further, this locomotive brake resistance device also comprises the steel construction tank bracket that is used for fixing blower fan, air ducting and described a plurality of resistance units.
Further, described steel construction tank bracket end is provided with the venetian blind type exhaust outlet, so that hot blast is discharged to the locomotive top, avoids the injury to personnel.
Further, described air ducting is a hemispherical dome formula structure, and the pars intermedia of air ducting is provided with the wind-guiding mesh plate, so that the cold flow distribution is more even, and corrects the turbulent flow in the cooling air.
The utlity model has positive effect: when (1) locomotive brake resistance device of the present utility model uses, air is sent into air ducting by blower fan, and through wind-guiding mesh plate guiding and after separating evenly, directly flows through the resistance grid, discharge from exhaust outlet then and enter atmosphere, thermal diffusivity is splendid.(2) the resistance grid changes " sheet " into by " banded bending ", and the two ends welding is inserted on the insulation frame fixing in the equidistant hole, effectively guarantee creepage distance between sheet, and the resistor disc adstante febre is not yielding, has improved useful life.(3) when resistance unit breaks down, can directly change this resistance unit separately, do not need installing big disintegration, as long as open cover plate, unclamp connection copper bar and fixed screw and can extract replacing out.So have characteristics easy to maintenance and that maintenance cost is cheap.
