Description
Technical field
The utility model relates to locomotive rheostatic brake technical field, particularly a kind of 8G locomotive rheostatic brake opening machine system test device.
Background technology
8G locomotive brake mode is divided into air brake and rheostatic brake.Rheostatic brake mode is utilized the principle of reversibility of DC machine, when damped condition, changes DC traction motor into dynamo generator, by wheel, to changing the kinetic energy of train into electric energy, consumes in braking resistor, and finally the form with heat energy is emitted in atmosphere.
The many advantages possessing with respect to air brake due to rheostatic brake is considered to the first-selection of electric power type locomotive brake system, but rheostatic brake still exists some limiting factors to make the safe operation of locomotive be subject to certain threat.Wherein limiting factor mainly comprises following 2 points: the first, if the restriction of maximum exciting current--limiting excitation winding over this can generate heat, and seriously understands scaling loss winding; Magnetic circuit is saturated on the other hand, and magnetic flux increases limited, and regulating effect is not obvious; The second, maximum braking current restriction--depend on the operation temperature rise of the armature loop of DC motor, the persistent current while being generally no more than normal traction working condition.
Therefore, for guaranteeing the normal operation of 8G locomotive rheostatic brake system, on train, need to be equipped with the proving installation of rheostatic brake system, requirement can Real-Time Monitoring rheostatic brake working state of system, the voltage/current mode chart that can show in real time Key Circuit, for technical personnel reference, for switching value/analog input and output fault, can show in real time and provide respective handling instruction, but also there is no such proving installation at present.
