The specific embodiment
Like Fig. 1, Fig. 2, Fig. 3: automobile-used double-generator parallel operation of the present invention system comprises first electrical generator 2 that is driven by driving engine 1 train; If second electrical generator 5 by change speed gear box 3, power takeoff 4 drivings; Change speed gear box 3 connects power takeoff 4; The output shaft of power takeoff 4 drives the dynamical axis of second electrical generator 5 through transmission device, and two electrical generators are through power cable 7 parallelly connected power equalizations outputs.
Described transmission device comprises power takeoff belt pulley 4a, the second dynamo pulley 5a, connects the odontoid belt 6a of the power takeoff belt pulley 4a and the second dynamo pulley 5a, and belt tension regulating mechanism 6b realizes degree of tension control to odontoid belt 6a.
The transmitting ratio of the power takeoff belt pulley 4a and the second dynamo pulley 5a is 1:3.
Be connected through power-transfer clutch 8 between described change speed gear box 3 and the power takeoff 4,8a is the clutch operating handle.The below of power takeoff 4 is established 11 pairs of power taking power facilities of backplate and is carried out the actv. protection, and backplate 11 is connected on the left and right sides vehicle frame 10, and horizontal positioned is carried out the actv. protection to the power taking power facility.
As shown in Figure 1, first electrical generator 2 drives rating horsepower 28V/4Kw by driving engine 1; Second electrical generator 5 drives rating horsepower 28V/4Kw by change speed gear box 3 through power takeoff 4.Two generator output ends are through power cable 7 parallel connections, and its negative pole is communicated with through engine assembly, transmission assembly.Operation clutch operating handle 8a, power-transfer clutch 8 realize power takeoff work and the control that stops.
Fig. 4 is multifunction regulator and electrical generator bonded assembly electrical schematic diagram.
The core of multifunction regulator is the IC control chip, and its principle of work is:
After ignition lock K connected, indicator lamp was bright, and multifunction regulator gets electric, the output duty cycle of IC control chip power controlling pipe Q.Storage battery V (24V) provides exciting current to generator amature through the B+ end, and rectifier bridge P point has signal to produce, and P point voltage signal and frequency increase with generator speed; When P point signal reaches the frequency set in the IC control chip and voltage; Indicator lamp extinguishes, and electrical generator (28V/4Kw) becomes self-excitation by separate excitation, and electrical generator B+ terminal voltage raises with rotating speed; When electrical generator B+ terminal voltage during greater than battery tension V, electrical generator begins external power supply.The IC control chip is according to load variations, and promptly the output duty cycle of B+ terminal voltage power controlling pipe Q provides the purpose that supplies exciting current thereby reach according to the load size for electrical generator.
