At present all kinds of factories and miness of China have 2.5 tons, 5 tons, 8 tons, 12 tons and 18 tons until higher tonnage model with the narrow gauge battery locomotive, corresponding batteries has 48V, 60V, 80V, 90V, 110V, 132V, 140V, 192V, 256V even higher direct voltage grade, the DC series motor is mostly adopted in the electric driving of existing narrow gauge battery locomotive, and rheostatic speed regulation type or chopping regulating speed scheme are then adopted in speed governing.Small part then adopts threephase asynchronous machine, and technology such as frequency conversion are adopted in speed governing.
There are a lot of drawbacks for employing DC series motor driven systems, as:
1) power consumption is big, the inefficiency of series DC machine, DC traction rheostatic speed regulation locomotive, the feedback function that in the car brakeing process, mostly do not generate electricity, the electric power of DC traction stringing rheostatic speed regulation locomotive start and the process of retarding braking in also with energy consumption in vain on resistance.
2) maintenance capacity is big, owing to many groups contact of speed regulator, cut easily arcing scaling loss in the switching operating process of sheet, often polish even change, and maintenance capacity is big.
3) DC motor is damaged and the maintenance rate height, because copperhead commutator and carbon brush that DC motor must have, this just must cause the damage amount and the maintenance capacity of DC motor bigger.
4) mechanical wear is big, in braking procedure, owing to there is not an electric braking function, needs to adopt the machinery friction catch of stopping, and causes stop piece and serious wear of wheel.
With respect to the threephase asynchronous drive system, the permagnetic synchronous motor drive system has higher efficient, the more excellent characteristics of speed adjusting performance.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, a kind of narrow gauge storage battery permagnetic synchronous motor car is provided, this electric locomotive adopts AC permanent-magnet synchronous motor and speed setting controller to form electrical system, has realized the application of permagnetic synchronous motor drive system on electric locomotive.
The utility model purpose realizes being finished by following technical scheme:
A kind of narrow gauge storage battery permagnetic synchronous motor car, described electric locomotive includes vehicle frame and is installed on running gear, storage battery on the described frame, it is characterized in that: also include AC permanent-magnet synchronous motor and speed setting controller, described speed setting controller have main control unit and be subjected to the control of described main control unit from control unit, main control unit and by the power cell control connection one AC permanent-magnet synchronous motor is arranged respectively from control unit, wherein main control unit also is connected with direction shelves, velocity setting system, observation window.
Be provided with position transducer, temperature sensor in the described AC permanent-magnet synchronous motor, described position transducer, temperature sensor are communicated with speed setting controller by holding wire.
The utility model has the advantages that:
1) hauling ability is better, and when low-frequency starting, starting torque is big, AC permanent magnet synchronous motor is reached and surpasses the starting torque and the pulling figure of direct current machine.Satisfy the maximum starting tractive effort of locomotive when low speed, make locomotive band heavy-load start strong and powerful.
2) maintenance capacity is littler, permanent-magnetic synchronous motor rotor does not have coil and commutation copperhead, and the driver controller non-contact does not have the maintenance load that causes because of mechanical wear substantially, the braking of driving process mechanism is replaced by motor brake greatly, and the wearing and tearing in the braking procedure significantly reduce.
3) saves energy, efficient compare direct current machine and three asynchronous motors obviously want high a lot, simultaneously under the locomotive brake situation, locomotive can be to charging power supply, thereby has reduced electric quantity consumption, the mileage of the charge operation that extended, reduced the charging power supply number of times, the economize on electricity saving of labor.
4) system is more reliable, and system can realize real-time monitoring to signals such as the speed of service of motor, temperature, and controller can realize protecting automatically and reporting corresponding fault when breaking down, and can guarantee that controller and motor driven systems reliablely and stablely move.
5) have battery management system in the control system,, will stop battery and cross and put phenomenon, thoroughly solve battery short problem in useful life by in drive system, increasing battery management system.
Description of drawings
Accompanying drawing 1 is the utility model embodiment electrical schematic diagram.
Embodiment
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technical staff's of the same trade understanding:
As shown in Figure 1, label is represented respectively: AC permanent-magnet synchronous motor M1, M2, power cell 1, power cell 2, main control unit 3, from control unit 4, storage battery 5, direction shelves 6, velocity setting system 7, position transducer 8, temperature sensor 9, output display device 10.
Narrow gauge storage battery permagnetic synchronous motor car is divided into machinery and electric two parts, mechanical part comprises: bicycle frame device, handwheel mechanical brake device, sander, running gear, spring assembly, drivers' cab ceiling, seat, buffer, bell etc., this is a prior art, and its structure does not repeat them here.
Referring to Fig. 1 (8 tons of electric locomotives with direct voltage 144V are example), electric part comprises: AC permanent-magnet synchronous motor M1, M2, storage battery 5, direction shelves 6, velocity setting system 7, output display device 10 and speed setting controller.
Speed setting controller has main control unit 3 and from control unit 4.Wherein, main control unit 3 is by storage battery 5 power supplies, and control connection has power cell 1, and power cell 1 is except that accepting 3 control signals transmitted of main control unit, also connect the direct current that the 144V that storage battery 5 provided is arranged, and it voltage A, B, C three-phase that is converted into Frequency Adjustable is sent into two AC permanent-magnet synchronous motor M1; Same principle has AC permanent-magnet synchronous motor M2 from control unit 4 by power cell 2 control connections.In addition, main control unit 3 also is connected with direction shelves 6 and velocity setting system 7, and by holding wire be connected from control unit 4.During the operating electrical machines car, by these direction shelves 6 and velocity setting system 7 input of control commands, main control unit 3 is accepted also to handle above-mentioned control command, and control signal is transferred to from control unit 4, with the cooperation that realizes two AC permanent-magnet synchronous motors (M1, M2) and synchronously.Simultaneously, main control unit 3 transfers to signal in the output display device 10, showing the running status of electric locomotive as observation window, as: information such as supply power voltage, the speed of a motor vehicle, operation troubles.When two AC permanent-magnet synchronous motor M1, M2 are driven by external force and when making the rotor rotation, then become alternating current generator, this moment, the conversion by speed setting controller can realize the charging to storage battery 5.
