Description

The AC permanent-magnet constant voltage generator

The utility model relates to a kind of AC permanent-magnet constant voltage generator, is specially adapted to be contained on the diesel engine flywheel shaft and generates electricity.

Work on the diesel engine at present according to being mostly to adopt the outer Blast Furnace Top Gas Recovery Turbine Unit (TRT) of the flywheel that constitutes by casing, rotor, stator, coil with bright power supply or adopting storage battery, this power supply form is is not only installed and used inconvenience, the expense height, weak effect, and easily lose (stolen), oil consumption is many, moisture-sensitive or shake badly, the normal work of influence is used, even also can cause easily outer accident because of outage.

The purpose of this utility model is exactly the actual needs at above-mentioned situation and diesel engine work illumination, and a kind of novel AC permanent-magnet constant voltage generator is provided.

The purpose of this utility model is achieved like this, adorn a rotor, stator, coil, automatic voltage regulator in the enclosure, rotor drives by the diesel engine flywheel, the cased gardens of radian triangle such as stator employing are on week, be wound with required coil on the stator, automatic voltage regulator is contained in the generator coil current output terminal.

The utility model is simple in structure, and is easy to install, stable performance, shockproof antitheft protection against the tide, fuel-economizing, the life-span is long, and when diesel engine low-speed running (600 rev/mins), car light does not shade, and does not burn filament when running up (2200 rev/mins), and remains storage battery brightness.

Below in conjunction with accompanying drawing structure of the present utility model is elaborated.

Fig. 1 is structure vertical view of the present utility model (wherein half is for throwing off the dust cap internal structure, and dotted line is other two stator coil positions).

Fig. 2 cuts lateral plan open for the utility model position of center line.

By shown in Figure 1, the utility model is to be made of shell 2, dust cap 1, rotor 4, stator 10, coil 6 and automatic voltage regulator 7, twine insulation enamel-cover conductor coils 6 on the stator 10, stator is fixed in the shell 2, stator winding is connected on the binding post 9 on the shell 2, in the shell 2 of binding post one side automatic voltage regulator 7 is housed, ring-type rotor 4 is housed in the stator interior.Coil 6 on the stator 10 is the insulation enamel-cover conductor coils that twine single-phase bilayer or three layer of 44 circle 0.8mm in the direction of the clock, every layer every line is headtotail successively, and be cast with insulating varnish, stator winding divides three groups to be fixed on shell 2 interior three positions such as arc such as grade, and extract 6 or 12 the end of a thread respectively out, two or four, six roots of sensation joint are drawn by the coil two ends in the connection back, are connected on respectively to be fixed on three binding posts that have insulating sleeve 12 on the shell.

Said stator winding divides identical three groups, every group of coil 6 twines in the direction of the clock, 2 layers of every wire-wounds, every layer around 44 circles, two-layer is 88 circles, with 0.9mm insulated copper enamelled wire, single-phase one tunnel (12V30W) use respectively three lines on three stators each in the direction of the clock around 2 layers totally 88 layers, the tail end of first winding of three stator winding connects the head end of second winding then, the tail end of second winding connects the head end of the 3rd winding, be that they are serially connected, single-phase two tunnel (12V60W) respectively connect clockwise direction with 2 lines respectively with 6 lines respectively and respectively enclose for totally 4 layer 176 around 2 layers on three stators, order one tunnel connection mutually then, two coils are corresponding more respectively on three stator winding of different layers is serially connected, and two road last 4 joints are head and head again, tail be connected together mutually with tail (promptly and connect), same three tunnel (12V90W) enclose with three wire-wounds 264 on every stator, and the line of organizing repeatedly on the same level is serially connected, and then first, tail connects together respectively.Every road group the end of a thread end is zero line (line forges iron), and tail end is a live wire.Add insulating paper between the group line of every road, and casting insulated lacquer.Deciding winding for three is fixed on interior three of shell 2 with screw 11 respectively and waits on the arc positions (see among Fig. 1 shown in the dotted line), by every map double-end two or four, six roots of sensation joint, be connected on respectively by screw and having on the shell 2 on three binding posts 9 of insulating sleeve 12, with screw 8 automatic voltage regulator 7 is housed in the shell 2 of binding post one side, and is connected with one in three binding posts.

During use, rotor is contained on the diesel engine flywheel shaft with screw 5, and the stator coil shell then is contained in big watt of groove of diesel engine, puts dust cap 1 then, fastening good with screw 3, but must satisfy coaxial requirement, at this moment, as long as cause diesel engine, drive rotor motion by flywheel shaft, producing magnetic field can generate electricity.

For the ease of wiring and maintenance, connect the power line of three black, white, red different colours in three wiring of generator respectively, black line is the generator line that forges iron, being connected on any one position of car body fixes and gets final product, white line is the automatic voltage regulator lead-in wire, red line is the generator live wire, and white, red two lead-in wires are connected on the terminal of lighting switch simultaneously, in order to the far and near light of control car light.

The utility model is fit to be installed on the diesel engine of different model, as all no storage battery vehicle operating illumination power supplys such as hand steered, four-wheel tractor, agricultural motor three-wheels, and the utility ratio height, prospect is far wealthy.
