Abstract
The utility model discloses a power supply device of a rail vehicle. The power supply device comprises a step-down transformer and a step-up transformer, wherein one end of the step-down transformer is connected with a power incoming line, and the other end of the step-down transformer is connected with a vehicle body power supply structure; one end of the step-up transformer is also connected with the vehicle body power supply structure, and the other end of the step-up transformer is connected with a direct current motor through a single-phase full-bridge rectifier; 380 V alternating current passes through the step-down transformer to obtain 36V alternating current which is connected to a rail and a conductor rail of the vehicle body power supply structure; the 36V alternating current in the rail is increased to 56V through the step-up transformer via a touch block on the vehicle body, is then changed into 48V direct current through the single-phase full-bridge rectifier and is supplied for driving the direct current motor to operate; electric potential on the rail and the vehicle body is not electrically and directly connected with the power incoming line and direct current voltage for driving the motor; and thus, the safety of operation personnel and equipment is guaranteed.
Description
Technical field
The utility model relates to the electric supply installation of battery-driven car, is specifically related to a kind of rail vehicle electric supply installation.
Background technology
Rail flat car is industrial and mining enterprises, the transportation means of large enterprise's indispensability particularly, the rail power supply is the direction of rail flat car development in recent years, comparing with other forms of rail flat car has its unique advantage, mainly be that power source obtains conveniently, the maintenance of equipment amount greatly reduces, but general rail power supply rail car must make wheel and car body insulation, this is because rail send the electric rail flatcar, send electricity by two rails and center conductor rail, if defective insulation will cause power supply short circuit, accomplish the insulation of wheel and car body, generally between wheel and axle, do a nylon jacket, this nylon jacket is in long-term weight and long-term use procedure, and is easily aging, break, so just destroyed complete vehicle structure, cause car body insecure, even electric leakage can't be used.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of rail vehicle electric supply installation, can be in the situation that car body and wheel not be done insulation, adopt the power supply of track and conductor rail, guaranteed the safety of operating personal and equipment, have characteristics simple in structure, easy to use.
To achieve these goals, the technical solution of the utility model is:
A kind of rail vehicle electric supply installation, comprise step-down transformer 1 and step-up transformer 2, one end of described step-down transformer 1 is connected with electric power incoming line, the other end of step-down transformer 1 is connected with the car body electric power-feeding structure, described step-up transformer 1 one ends also are connected with the car body electric power-feeding structure, and the other end of step-up transformer 2 is connected with DC machine 4 through single-phase full bridge rectification 3.
Described car body electric power-feeding structure comprises rail 5 and conductor rail 6.
Described step-down transformer 1 adopts 380/36V single-phase dry type step-down transformer.
Described step-up transformer 2 adopts 36/56V single-phase dry type step-up transformer.
Because the electrical isolation effect of step-down transformer 1 and step-up transformer 2, so that the current potential on track and the car body and electric power incoming line, the vdc of drive motor does not all have the direct connection of electricity, has guaranteed the safety of operating personal and equipment.
Description of drawings
Fig. 1 is structure principle chart of the present utility model.
Fig. 2 is the utility model fundamental diagram.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
With reference to Fig. 1; a kind of rail vehicle electric supply installation; single-phase 380V alternating current is opened insurance through sky; main contactor connects 380/36V single-phase dry type step-down transformer 1, under the protection of oversampling circuit, on rail 5 and conductor rail 6 in the 36V alternating current access car body electric power-feeding structure; again by the mill contact block on the car body; 36V alternating current in the rail is upgraded to 56V by 36/56V single-phase dry type step-up transformer 2, becomes the 48V direct current (DC) through single-phase full bridge rectification 3 again, and supply with 4 runnings of driving DC machine.
With reference to Fig. 2; a kind of rail vehicle electric supply installation; the 380V electric power incoming line is by the first knife-like switch QS; main contactor FU is connected with 380/36V single-phase dry type step-down transformer 1; the end of main contactor FU also is provided with circuit overcurrent protection; 380/36V single-phase dry type step-down transformer 1 is by rail 5 and conductor rail 6 in the current relay 7 connection body electric power-feeding structures; 36/56V single-phase dry type step-up transformer 2 also with the car body electric power-feeding structure in rail 5 link to each other with conductor rail 6; and by the second knife-like switch QS 2 connection single-phase full bridge rectifications 3, single-phase full bridge rectification 3 is imparted to DC machine 4 with electric energy.
Because what use in the car body is the 36V safety voltage, car body and electric power incoming line drive the vdc of DC machine all less than directly connecting, and have guaranteed the safety of operating personal and equipment.
Above demonstration and described groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
