Below in conjunction with Fig. 2 24 volts of dynamo generator voltage regulators of the utility model embodiment self-excitation type and integrated circuit electric power thus supplied are elaborated.
(1) service condition of guillotine 27
Electrical generator 9 stops or during low speed rotation, shunt winding 25 do not have magnetic field to produce or magnetic field very weak, the suction of iron core 23.1 can not overcome the pulling force of spring 22, can not inhale lower link 19.1, contact 21.3 is what to separate with connecting rod 19, and the electric current of electrical generator 9 can not export electric light A, Der Blink und Abblendschalter B, loud-speaker C, electrical motor 10, storage battery 7 even loads to from the carbon brush negative pole.
When electrical generator 9 rotating speeds raise, its voltage also increases (voltage that generally is higher than storage battery), make shunt winding 25 produce enough magnetic-field intensitys, overcome the pulling force of spring 22, iron core 23.1 is inhaled connecting rod 19.1 down, contact 21.3 closures, the electric current of electrical generator 9 carbon brush negative poles to series coil 26, are exported two-way through connecting rod 19.1, contact 21.3 etc.: one road to K switching lamp A load through air restrictor main coil 24 again; Another road forms the loop to amperemeter/ammtr 8, Der Blink und Abblendschalter B, loudspeaker C, electrical motor 10, storage battery 7 even loads.
The electric current of electrical generator 9 flows back to the process of storage battery 7: shunt winding 25 is consistent with the magnetic direction of series coil 26, so contact 21.3 can remain on closed state with connecting rod 19.
If the rotating speed of electrical generator 9 reduces, its voltage is lower than the voltage of storage battery 7 again, and the electric current of storage battery flows to electrical generator 9 carbon brush negative poles from negative pole through amperemeter/ammtr 8, connecting rod 19, contact 21.3, connecting rod 19.1, series coil 26 to air restrictor main coil 24.At this moment sense of current is to turn (but the direction of current in the shunt winding 25 is constant) around in the series coil 26, the magnetic field of its magnetic field and shunt winding 25 is opposite, therefore weakened the magnetic field of iron core 23.1, suction reduces, the pulling force of spring 22 separates contact 21.3 and connecting rod 19, cut off circuit, storage battery 7 cathodal currents can not flow to electrical generator 9 carbon brush negative poles, do not form the loop.About 0.5～3 peace of counter-current when contact 21.3 separates is to not infringement of electrical generator.In the case, shunt winding 25 is also by storage battery power supply.
(2) service condition of air restrictor 28
The electric current of electrical generator 9 carbon brush negative poles output all flows back to electrical generator carbon brush positive pole by main coil 24, the series coil 26 of guillotine, the shunt winding 25 of air restrictor, forms the loop.When the outgoing current of electrical generator 9 less than limit 13-15 peace, contact 21.2 closures of air restrictor, the energizing circuit of electrical generator is as the explanation of " service condition of pressure governor " part, when outgoing current 15 peaces in excess of the quota, open contact 21.2, its circuit:
Electrical generator 9 carbon brush positive ground lines divide two-way through pole winding 20 to iron core 23 back: the 1 road to the contact 21.1, resistance R
32 the road to resistance R
1With R
2, iron core 23.2, pole winding 30, main coil 24, electrical generator carbon brush negative pole, form the loop.
Owing to increased (R in the circuit
1+ R
2) R
3/ (R
1+ R
2)+R
3Resistance, so exciting current reduces, generator voltage (pressure governor keep stationary value) is descended again, the electric current of electrical generator 9 outputs just drops to below the limit thereupon, at this moment contact 21.2 is closed again, voltage rises again, outgoing current increases again.Contact 21.2 constantly vibrates like this, and outgoing current is limited in 15 peaces all the time, and electric current does not continue to increase with the load increase, prevents and protected the overload of electrical generator.
(3) service condition of pressure governor 29
Electrical generator 9 rotates generating, and the magnetizing coil 21 of pressure governor has electric current to pass through, and electric current increases with electrical generator 9 terminal voltages and increases its circuit:
Electrical generator carbon brush positive ground line is through magnetizing coil 21, resistance R
2, iron core 23.2, pole winding 30, main coil 24, electrical generator carbon brush negative pole form the loop.
When electrical generator 9 voltages are lower than 27 volts of limits, pressure governor contact 21.1 closures, its energizing circuit:
Electrical generator 9 carbon brush positive ground lines to iron core 23.3, contact 21.1, pole winding 30, main coil 24, electrical generator 9 carbon brush negative poles, form the loop through pole winding 20.
This moment, field current was only through contact 21.1, without resistance, so electrical generator 9 terminal voltages increase with the rotating speed rising.
When a little higher than 27～29 volts of electrical generator 9 voltages, the suction that the electric current in the magnetizing coil 21 produces in iron core 23.3 is big, and contact 21.1 is inhaled opens, and field current is forced through resistance R
1, its change partial circuit: ... electrical generator 9 magnetic fields are to iron core 23.3, resistance R
1With R
2, iron core 23.2 ...
Because of having sealed in R in the field circuit
1+ R
2Resistance, so field current reduces rapidly, weakened field, generator voltage descend, because voltage descends, the electric current in the magnetizing coil 21 are reduced, iron core 23.3 suction reduce.Electrical generator 9 voltages are lower than 27 volts, and iron core 23.3 suction are little, and contact 21.1 is closed again, and generator voltage raises again.When surpassing 27 volts, open again contact 21.1, opens and closes so repeatedly, and the field current of electrical generator 9 is not increased with the rotating speed rising, and it is basicly stable under middle and high speed to have kept generator voltage.
The regulator circuit characteristics
1. the contact of air restrictor and pressure governor all is to be connected in the energizing circuit, can regulate exciting current by the switching of contact, and the rotation speed change of it and electrical generator is adapted.
2. air restrictor is that outgoing current according to electrical generator comes work, and electrical generator all must be by the main coil of air restrictor to the electric current of vehicle circuit output.
3. the magnetizing coil one termination ground wire of pressure governor, the other end is connected on resistance R
1And R
2Between, purpose is in order to pass through R
2The oscillation frequency that is used for improving the pressure governor contact.
4. also design each specification of technical data that 12 volts of self-excitation types and separated exciting 24 overhead generators are arranged in addition, select for use for two kinds of vehicle models.
Because between electrical generator, electrical motor, the voltage regulator three is that interconnect architecture is matching used, so voltage, electric current, rotating speed, temperature rise, power of designing it etc. must reach synchronous with machinery support, vehicle just can travel and generate electricity and charging, reaches the advanced vehicle of innovation.Designing technique data demand between the three is very compact, accurate, particularly the design of self-excitation type electrical generator and development require very meticulous, otherwise can not generating-charging, can not replenish power supply.
Characteristic according to storage battery, adopt the constant potential mode to charge, charging rate is very fast like this, carries out along with electrically-charged, and electrically-charged electric current can reduce, because of voltage regulator is arranged, it is suitable that voltage is set, meeting automatic stop function during charging, and shortcoming is to guarantee that storage battery is thoroughly sufficient, but the chance of generator charging is many during work, and is little to this problems affect.The voltage of constant-voltage charge is in 27～29V scope, and in process of charging, because the electro-motive force of battery increases gradually, charging current reduces gradually, until being bordering on zero.
