Compared with traditional electromagnetic and electronic regulators, the utility model has the advantages of simple and direct circuit, high reliability, strong anti-overload capability, energy saving, over voltage indication, low cost, convenient installation and operation, etc. The utility model can be widely used for various motor vehicles to automatically control the magnitude of the voltage. The utility model has the advantages of high universality and good compatibility and is suitable for mass production in factories.
Description
The utility model relates to a kind of adjuster of auto-control generator output voltage.
For many years, both at home and abroad voltage regulator for automobile adopts electromagnetic type mostly, and this installation cost merchant, volume are big, and poor reliability need often be carried out specialty adjustment, and power consumption is big, and static power consumption stream reaches 2.5A, self-heating, contact chatter arcing, ablation easily.This electricity-eating tiger is equivalent to length and connects a 30W bulb, and electric weight consumes in vain.Numerous automobiles, the accumulative total energy loss is big, can't bear imagination.
In recent years, the various kinds electronic voltage regulator is come out one after another, volume is less, saves energy, use installation more convenient, but reliability is generally relatively poor, in case load short circuits, misconnection, reverse, faults such as the full load large throttle goes offline suddenly, lights occur, adjuster damages at once, causes mortality to threaten to bulb, power device thereupon.Though the external existing electronic type product of protection automatically of being with occurs, and components and parts are required harshness, specificity is strong, and price is very expensive.
This Study on Technology purpose, be on the basis of the performance of summing up similar products at home and abroad, characteristics, economic and technical norms, produce excellent performance with the simplest and the most direct method, the reliability height, good stability, load capacity is strong, and is energy-efficient, has the novel voltage adjuster that prolongs the bulb service life function.The advantage of this device current collection magnetic-type, electronic voltage regulator is an one, fundamentally overcome the electromagnetic regulator volume big, adjust cumbersome, power consumption big, poor stability and general electronic type regulator anti-overload ability is poor, reliability is low, the life-span is short, the delicate shortcoming such as fragile of performance.
This efficient automobile voltage regulator by shell, patch electrode, automatic voltage control circuit is formed, it is characterized by in its automatic control circuit, the miniature relay that utilizes a superior performance is as holding the energy device, and normally-closed contact links with generating Polar armature electrode F end; Normally opened contact and light-emitting diode link; Moving contact and positive electrode link; Relay coil is connected in the automatic control circuit.Potentiometer VR connects with voltage-stabiliser tube DW, and access transistor BG base circuit is used to adjust the voltage control point.
This adjuster is by the output voltage of automatic control circuit detection automobile current generator, and when voltage raise and reaches limit value, the actuating of relay was cut off generating utmost point magnet exciting coil supply current, thereby made the instantaneous generation outage of generator.Because the generator output circuit is in parallel with storage battery and load, total voltage descends, and again armature circuit is connected immediately, and generator is normal power generation again again, and voltage raises, and when reaching limit value, repeats said process, the purpose of realization auto-control voltage.
Characteristics of the present utility model are: power big (load capacity is strong), and the maximum allowable operating current reaches 12A, therefore may be used for domestic and international various automobile (comprising heavy-duty car, luxury car, special car etc.); Overload-resistant power is extremely strong, has both made at armature line bonding, internal short-circuit, opens circuit suddenly, serious situation such as sparking, does not still damage; Circuit is simple and direct, the reliability height, and control voltage is adjustable; Cost is low, and components and parts are not had strict demand, and economic performance is good; High conformity is suitable for factory and produces in batches; Have the overvoltage deixis, when supply voltage surpass the sentinel valve limit (during gasoline car 14 ± 0.3V/ diesel vehicle 28 ± 0.5V), cut off the power supply of F end automatically, bright during overvoltage indicator light LED; Voltage just often, indicator light extinguishes, the operating state that helps monitoring at any time.
The circuit working principle is referring to Fig. 1.Potentiometer VR connects with resistance R, forms voltage divider.Voltage-stabiliser tube DW
