Description
The utility model relates to electricity field, promptly two excitatory stable-voltage generators.
At present, the illuminator of agricultural tricycle, carriage or tractor mostly adopts the permanent magnetism stable-voltage generator.The low speed effect of such generator is not ideal enough, runs into the road frustration, bend, during situation low speed drivings such as meeting, the rotating speed of this class generator descends with the rotating speed of engine, and output voltage is low, dimly lit road and the barrier of not seeing causes traffic accident easily.If the low speed power of this class generator is improved, will make power increase 3-6 doubly during then to high speed, can reduce the power output of engine like this.If as mains lighting supply then must assembled batteries, so not only can increase use cost, and maintenance be inconvenient with silicon rectification generator, be not suitable for vast rural area and uses.
The purpose of this utility model is a kind of novel electricity generator of design, realizes that idling reaches illumination needs, reaches rated voltage during low speed, middle and high output voltage stabilization when fast, and without storage battery power supply.
The purpose of this utility model is achieved in that by rotor, the two excitatory stable-voltage generator that stator and regulating circuit are formed, it is characterized in that: permanent-magnet pole (2) and electromagnetic pole (3) are housed on armature spindle (1), the lead-in wire of the magnetizing coil (4) in the electromagnetic pole (3) is by the A of slip ring (5), 2 of B draw, two outputs of stator coil (6) are in parallel with the two ends of the two ends of load R0 and bridge rectifier (7) respectively, and the positive pole of bridge rectifier (7) meets triode T1 respectively, the current collection collection of T2, the yoke (9) of bipolar double-contact trigger (8), one end of magnetizing coil (10) and central contact (11); The low speed contact K1 of bipolar double-contact trigger is the end of connecting resistance R4, R2 respectively, the base stage of another termination triode T4 of R4, the base stage of another termination T2 of R2, the high speed contact K2 of bipolar double-contact trigger is the end of connecting resistance R3, R1 respectively, the base stage of another termination triode T3 of R3, the base stage of another termination T1 of R1, the negative pole of bridge rectifier connects the other end of magnetizing coil, the collector electrode of triode T3, T4 respectively, the emitter of T2, T3 connects the A point of slip ring (5), and the emitter of T1, T4 connects the B point of slip ring (5).
The utility model has the advantages that:
1, idling is effective, and low speed reaches rated voltage, and middle and high fast voltage is stable.
2,, reduce use cost without accumulator jar.
3, can directly charge a battery by bridge rectifier, may be used on substituted for silicon commutator generator on the automobile.
4, because bipolar double-contact trigger provides triggering signal only for the bridge-type negative circuit, so its long service life.
Description of drawings: Fig. 1 is design principle figure of the present utility model, wherein: 1-armature spindle, 2-permanent-magnet pole, 3-electromagnetic pole, 4-magnetizing coil, 5-slip ring, 6-stator coil, 7-bridge rectifier 8-bipolar double-contact trigger 9-yoke 10-magnetizing coil 11-central contact 12-bridge-type negater circuit 13-adjustment spring K1-low speed contact K2-high speed contact R 1, R2, R3, R4-resistance R 0-load T1, T2, T3, T4-triode.
Below in conjunction with accompanying drawing the utility model is described further:
When generator when idle, the permanent-magnet pole (2) of armature spindle (1) produces rotating magnetic field and makes stator coil (6) produce electric current, gives the power supply of the magnetizing coil (10) in the bipolar double-contact trigger (8) after bridge rectifier (7) rectification.Because voltage is low, the magnetic force that produces does not overcome the pulling force of adjusting spring and central contact (11) is contacted with low speed contact K1, at this moment electric current makes the magnetizing coil (4) in T4, the T2 conducting electromagnetic pole (3) on armature spindle (1) that forward current is provided through K1, R4, R2, the magnetic field that electromagnetic pole is produced is identical with the magnetic direction of permanent-magnet pole, thereby strengthened the magnetic field intensity of rotor, the output voltage of generator is improved.When generator in, during low cruise, at this moment generator output voltage has reached rated voltage, the magnetic force of magnetizing coil (10) strengthens, overcome the pulling force of adjusting spring (13) and central contact (11) and low speed contact K1 are broken away from, at this moment T2, T4 is in cut-off state owing to lose trigger voltage, and can not get voltage, magnetizing coil (4) make electromagnetic pole (3) lose magnetic field, thereby weakened the magnetic field of rotor, and the output voltage of generator is reduced, at this moment central contact (11) is connected T4 with K1, T2 obtains trigger voltage and conducting, electromagnetic pole (3) produces magnetic field, and generator output voltage is improved, the voltage that makes generator that moves in circles like this is stabilized in the designing requirement T3, T1 is in cut-off state owing to can not get triggering pressing.When generator during in middling speed, central contact (11) is in the center (not contacting with K1, K2) of K1, K2 under the effect of magnetizing coil (10), make T1, T2, T3, T4 can not get trigger voltage and all locate cut-off state.At this moment, electromagnetic pole (3) does not produce magnetic field, and generator reaches designing requirement by the permanent-magnet pole generating.When generator in middle and high when operation speed, at this moment generator output voltage is higher, and magnetizing coil (10) produces than high-intensity magnetic field, overcomes the pulling force of adjusting spring (13), central contact (11) and high speed contact K2 are connected, and triode T3, T1 obtain trigger voltage and conducting.At this moment T2, T4 end, and magnetizing coil (4) obtains reverse current, and electromagnetic pole (3) produces and the opposite magnetic field of permanent-magnet pole (2), thereby have weakened the magnetic field of rotor, generator output voltage is reduced, and the output voltage of generator is remained in the rated range.
In sum, generator is in running, the vibration of the central contact by bipolar double-contact trigger, make triode T1, T2, T3, T4 conducting, by or not conductings, forward current or reverse current are provided or electric current is not provided to magnetizing coil, thereby the output voltage stabilization that makes generator is in certain scope.
