Description
Technical field
The utility model relates to a kind of power frequency internal combustion engine generator.
Background technology
Small-sized power frequency gasoline engine generator is subjected to users' favor simply deeply as family expenses emergency power supply and field work power supply because of easy to carry, low price, use.
At present, the power frequency gasoline engine generator is divided into AVR by the difference of excitation mode brush automatic Regulation excitation and brushless capacitive excitation, and these two kinds of excitation systems respectively have pluses and minuses.AVR has the performance of brush automatic Regulation excitation generator will get well a lot, but price is more expensive, and because the existence of carbon brush needs the user to safeguard.
And brushless capacitive excitation electric generator structure is simple, low price, failure rate is low and need not to safeguard, but the performance at aspects such as voltage regulation and excitation frequencies is not very desirable, brushless capacitive excitation generator carries out excitation by electric capacity and auxiliary winding, then to play magnet rate low more when capacitance is big more, but generator property is very soft, and voltage regulation can't reach requirement at all; And capacitance is too small, and it is too high then to play magnet rate, and generator can't generate electricity when normal the use.Take into account this two aspect and can only improve methods such as material property, but the manufacturing cost of motor increase greatly like this, is impracticable certainly in today that competition increasingly sharpens by increasing motor volume.
Summary of the invention
In order to overcome the deficiency that can not take into account magnet rate, voltage regulation of existing power frequency internal combustion engine generator, the utility model provides a kind of can take into account magnet rate and voltage regulation, power frequency internal combustion engine generator that cost is low.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of power frequency internal combustion engine generator, comprise gas turbine, decelerator and brushless capacitive excitation generator, described brushless capacitive excitation generator comprises main winding, auxiliary winding, the direct current winding, described auxiliary winding and excitation capacitor C 1 are connected into the excitation circuit, the two ends of described main winding connect the output of generator, described direct current winding connects the direct current output of generator after rectification, and it is in parallel with the starting relay K that has normally closed switch k, described normally closed switch k and auxiliary capacitor C2 are connected into and start the excitation auxiliary branch, and described excitation capacitor C 1 is in parallel with startup excitation auxiliary branch.
Technical conceive of the present utility model is: referring to Fig. 1, solve the circuit of two-capacitance capacitive with relay K, C1 is that normal operating conditions is used electric capacity among the figure, relay K is normally closed at no electric situation lower contact, the coil of relay is attempted by the dc output end of generator, and C2 is when magnetize and C1 is in parallel uses, when generator sends the relay K disconnection of electricity back, normally closed switch k disconnects, and C2 no longer plays effect.This sharp structure is very simple, and comparing original generator has only increased capacitor C 2 and relay K, and cost does not almost increase, but significant lifting is arranged on performance.Voltage regulation by the generator of this production can be controlled at ± 5% scope in, can adjust along with the variation of capacitor C 2 and play a magnet rate, very easy to use.
The beneficial effects of the utility model mainly show: can take into account magnet rate and voltage regulation, cost is low.
Description of drawings
Fig. 1 is the structural representation of power frequency internal combustion engine generator.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Referring to Fig. 1, a kind of power frequency internal combustion engine generator, comprise gas turbine, decelerator and brushless capacitive excitation generator, described brushless capacitive excitation generator comprises main winding, auxiliary winding, described auxiliary winding and excitation capacitor C 1 are connected into the excitation circuit, the two ends of described main winding connect the output of generator, described direct current winding connects the direct current output of generator after rectification, and it is in parallel with the starting relay K that has normally closed switch k, described normally closed switch k and auxiliary capacitor C2 are connected into and start the excitation auxiliary branch, and described excitation capacitor C 1 is in parallel with startup excitation auxiliary branch.
Among Fig. 1, C1 is that normal operating conditions is used electric capacity, relay K is normally closed at no electric situation lower contact, the coil of relay is attempted by the dc output end of generator, C2 is when magnetize and C1 is in parallel uses, relay K disconnects after generator sends electricity, and normally closed switch k disconnects, and C2 no longer plays effect.Voltage regulation by the generator of this production can be controlled at ± 5% scope in, can adjust along with the variation of capacitor C 2 and play a magnet rate, very easy to use.
