Summary of the invention
The air that causes to subway tunnel when the utility model moves in order to solve existing subway diesel traction engine and the problem of noise pollution specifically are a kind of novel subway tractor truck electric actuators.
The utility model is to adopt following technical scheme to realize: novel subway tractor truck electric actuator, comprise driver controller AC, be subjected to the diesel engine CYJ of driver controller AC control, synchronous main alternator GS, with the rectifier 2UR that links to each other with synchronous main alternator GS mouth, the excitation coil of synchronous main alternator GS disposes the permanent merit excitation unit Iw that is subjected to driver controller AC control, the mouth of rectifier 2UR links to each other with traction motor M through contactless switch KM, comprise that also lifting is subjected to the pantograph AP of driver controller AC control, with the chopper 1UR that links to each other with pantograph AP, chopper 1UR disposes the impulse deviser Up that is subjected to driver controller AC control, the mouth of chopper 1UR links to each other with traction motor M through contactless switch KM, and the energizing signal end of permanent merit excitation unit Iw and impulse deviser Up links to each other with control power supply Uc through control transformation switch S A.
When subway power supply grid circuit (stringing net) just often, by driver controller AC the pantograph AP of tractor truck is risen and to contact with the power supply grid circuit, with the electrical network power transfer to chopper 1UR, after chopper 1UR conversion, give traction motor M, realize towage; When after the subway power supply grid line fault or do not have electrical network section when operation, start the diesel engine CYJ of tractor truck by driver controller AC, produce direct current (DC) by synchronous main alternator GS-rectifier 2UR, give traction motor M, realize running under power; Wherein, driver controller AC is responsible for producing driver's control command signal Ug, delivers to permanent merit excitation unit Iw, impulse deviser Up respectively, to produce permanent merit or constant-speed operation control signal; Permanent merit excitation unit Iw is responsible for controlling the exciting current of synchronous main alternator GS, under the diesel engine operating condition, according to feedback signal Uf, If control diesel engine power, car load is operated under the permanent account of somebody's meritorious service attitude, the best power of performance diesel engine; Impulse deviser Up produces the straight impulse singla Pulse of chopper 1UR always according to feedback signal Uf, If, and then control traction motor voltage, adjusts motor speed, and the tractor truck operation is moved by constant velocity characteristics; Control transformation switch S A be the driver to above-mentioned two kinds of select switches that condition of supplying power is selected, it produces change working signal A or B, and has interlock function, guarantees tractor truck in either case, has and have only a kind of operating mode to put into operation.Driver controller AC is by lifting bow circuit control pantograph AP lifting, and lifting bow circuit is existing known technology, therefore narrates in specification sheets.
Compared with prior art, the utility model is on the basis of diesel locomotive friendship-straight electric drive system, increase pantograph and DC chopped-wave power supply, make the metro traction car possess diesel engine-main generator, the stringing net-chopper structure that supplies power with double circuit, the driver only need be by control transformation switch S A conversion, just but Railway transportation capable particular case in stronghold is selected diesel engine or stringing net powered operation mode, reaches the optimum operation effect.Promptly make full use of the existing stringing supply network of subway, for tractor truck provides cleaning power; Only when the supply network fault, just enable diesel engine power is provided, can significantly reduce aerial contamination and noise jamming that diesel engine causes to subway tunnel.In time for shunt in the subway station field, emergency relief, construction operation provide traction power.
The utility model supplies power with double circuit, maneuverability, and convenient operation, clean environment firendly can significantly reduce air, noise emission that diesel engine brings to subway tunnel, makes things convenient for subway user towage, effectively improves the metro operation quality.
Description of drawings
Fig. 1 is schematic circuit diagram of the present utility model;
The specific embodiment
Novel subway tractor truck electric actuator, comprise driver controller AC, be subjected to the diesel engine CYJ of driver controller AC control, synchronous main alternator GS, with the rectifier 2UR that links to each other with synchronous main alternator GS mouth, the excitation coil of synchronous main alternator GS disposes the permanent merit excitation unit Iw that is subjected to driver controller AC control, the mouth of rectifier 2UR links to each other with traction motor M through contactless switch KM, comprise that also lifting is subjected to the pantograph AP of driver controller AC control, with the chopper 1UR that links to each other with pantograph AP, chopper 1UR disposes the impulse deviser Up that is subjected to driver controller AC control, the mouth of chopper 1UR links to each other with traction motor M through contactless switch KM, and the energizing signal end of permanent merit excitation unit Iw and impulse deviser Up links to each other with control power supply Uc through control transformation switch S A.
Under the diesel engine operation scheme, make the metro traction car carry traction power, have bigger maneuverability, the railway traction car is at electric network fault or there is not the operation of barrier section contentedly; Under stringing network operation mode, tractor truck relies on the existing supply network of subway clean energy resource is provided, and effectively reduces air and noise pollution in the tunnel, has satisfied the metro operation merchant requirement harsh day by day to environmental protection index.It is the novel subway hauling power device of a kind of maneuverability, easy to use, power cleaning.
Subway tractor electric actuator described in the utility model has following characteristics:
1, two kinds of power supply modes realize dual-use
Adopt subway power supply net and two kinds of power source presentation modes of diesel internal combustion engine, make the user can be according to concrete fortune The market condition, the flexible choice power supply mode both had been equivalent to flexibly diesel locomotive of a conveniently moving, and was again suitable Be subjected to the clean energy resource tractor of electricity in a stand line.
