Description

High-voltage excitation silicon rectification generator

The utility model relates to a kind of generator, relates to a kind of automobile-use high pressure excitation silicon rectification generator specifically.

Automobile-used generator is that the engine of car drives it and rotates generating, does not meet the road when not convenient for walking with the motor vehicle of storage battery when some, and engine speed is lower, and silicon rectification generator can not start because of there being storage battery power supply, often needs electricity consumption at this moment.It is two excitation silicon rectification generators of 91220329 that a kind of patent No. is arranged now, it is to add permanent magnet at original silicon rectification generator median claw interpolar, generator can be started under engine low rotation speed condition, but power generation performance is bad, the permanent magnet permeability is low, so volume is big, fragile, maintenance is inconvenient.

The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of high pressure excitation silicon rectification generator that just can start the rated voltage that also can provide stable in the motor car engine slow-speed of revolution is provided.

Generator of the present utility model has front and rear cover, power transmission shaft, the pawl utmost point, excitation winding and iron core, armature winding and silicon rectifier, electronic voltage controller, it also is provided with high pressure winding of Duoing than the armature winding number of turn and the silicon rectifier that is attached thereto, this high pressure winding is connected with excitation winding by this silicon rectifier, the silicon rectifier that silicon rectifier that armature winding connected and high pressure winding are connected, negative pole links to each other, the positive pole of the silicon rectifier of armature winding connects electronic voltage controller, instant voltage output signal is provided for it, one end of excitation winding inserts the negative pole of two silicon rectifiers by the filter capacitor of electronic voltage controller, the other end divides two-way to insert electronic voltage controller, electronic voltage controller can be according to the height of armature output voltage, leading to of control excitation winding electric current, disconnected, the induced current that the high pressure winding utilizes remanent magnetism to produce when time of engine low speed can pass through silicon rectifier, and be the excitation winding power supply, make generator energy excitation under engine low rotation speed condition, and can output rated voltage.Utilize voltage regulator to regulate output voltage when engine speed is high.

Advantage of the present utility model is that with regard to exportable rated voltage, its low speed power generation performance is better than two excitation silicon rectification generators when hanging down owing to the winding engine speed that adds high pressure; Adopt low charcoal steel soft magnetic bodies to make the excitation winding iron core in addition and adopt permanent magnet permeability height than two excitation silicon rectification generators, the equal-wattage motor volume is little; Permanent magnet is more crisp fragile, is hard to buy the permanent magnet of same size and material during maintenance, and it is easy to maintenance to adopt the high pressure ratio of winding.

Fig. 1 is the circuit theory diagrams of the utility model embodiment.

The utility model is described in further detail below in conjunction with embodiment.

As seen from Figure 1, L ₂Be armature winding, A, O are the binding post of armature winding two outputs, L ₂Be high pressure winding, L ₃Being excitation winding, is electronic voltage controller in the frame of broken lines; The high pressure winding L ₂Connect a bridge type silicon rectifier D ₅-D ₈, this rectifier and excitation winding L ₃Series connection, armature winding meets another bridge type silicon rectifier D ₁-D ₄, these two rectifier negative poles link to each other, rectifier D ₁-D ₄Positive pole and the R of electronic voltage controller in the frame of broken lines ₁Series connection provides instant output voltage signal, L for it ₃An end pass through C ₁Insert the negative pole of two rectifiers, the other end divides two-way to meet the R of electronic voltage controller respectively ₄And BG ₂Collector electrode, work as L ₂Be L ₃During power supply, its electric current I ₂One route BG ₂Collector electrode flow to D to its emitter ₅-D ₈The negative pole of rectifier, another road is through R ₄D ₁₁, BG ₂Base stage, emitter flow to D ₅-D ₈Negative pole.When engine speed when specified minimum speed is above, can make L by excitation winding iron core and remanent magnetism that magnetic pole is with ₂Produce an induced electromotive force, and produce induced current I ₂, L during design ₂Turn ratio L ₁Many, make induced electromotive force enough big, the induced current that is produced can pass through rectifier D ₅-D ₈Flow to L ₃, L ₃Magnetic field strengthened after electric current was arranged, and the output voltage of armature was increased, at this moment with regard to exportable rated voltage; When engine speed was very fast, electronic voltage controller obtained transmitting electricity and presses when being higher than the signal of rated voltage its voltage stabilizing didoe D ₁₀Breakdown, make BG ₂End I ₂The loop disconnect L ₃Because of the no current magnetic field intensity reduces, the armature output voltage decreases, and so just can make generator that stable output voltage is all arranged when engine speed change and load variations.This high pressure winding L ₂Also can connect with armature winding.
