Embodiment

Below in conjunction with specific embodiment, the technical program is explained in detail.

As shown in Figure 4, the utility model is a kind of intelligent voltage stepless regulator, generally be connected in main transformer loop, the pressure regulation potential device 2 comprising master controller 1 and be connected with master controller, pressure regulation potential device 2 adopts contact carbon brush loop construction, the coil 2-4 comprising motor, cursor slide 2-1, carbon brush 2-2, iron core 2-3 and be set around on iron core, motor connects and drives cursor slide 2-1, carbon brush 2-2 to be fixed on cursor slide 2-1 and with coil 2-4 sliding contact.Wherein, motor is connected with master controller, changes the output winding number of turn by the movement of main controller controls carbon brush, realizes stepless voltage-regulation function, remains and coil contact in carbon brush moving process, keeps in touch at least two circle coils during carbon brush moves.Motor is arranged on the middle part of iron core and coil, and the rotating shaft of motor stretches out, and one end of cursor slide is fixed in the rotating shaft of motor, and the other end installs carbon brush.

In the technical program, the smart circuit control system connection control pressure regulation potential device of master controller, compensates the transmission of voltage, for low voltage electric network provides reactive power compensation through compensator transformer 3.Smart circuit control system is by setting up reference circuit 4 and voltage sampling circuit 5, utilize the voltage data of voltage sampling circuit Real-time Obtaining current voltage data and reference circuit to compare, and carry out the amplitude of the electric machine rotation of control and compensation transformer with this and the time realizes Intelligent adjustment function.Wherein, voltage sampling circuit adopts voltage transformer summation current transformer, Real-time Obtaining current line magnitude of voltage; The voltage data obtained by voltage sampling circuit in real time by the Single-chip Controlling of smart circuit control system and the voltage data of reference circuit compare, and control the amplitude of electric machine rotation and the time realizes Intelligent adjustment function.

As Figure 1-Figure 4, voltage regulating transformer mainly serves as the voltage that affords redress, the size and Orientation of this bucking voltage all can change according to the movement of the cursor slide of voltage regulating transformer, this just can obtain in the low-pressure side of compensator transformer the bucking voltage that size and Orientation can change, the voltage that the meeting of this voltage and input provide carries out vector superposed, makes output voltage stabilization on required set-point.Lift an example to illustrate: input voltage U1=240V, requires output voltage stabilization UO=220V.So just have equation relation: the direction of UO=U1-△ U i.e. △ U is contrary with the direction of U1, size is just 20V.Input voltage U1=200V, requires that output voltage stabilization is at UO=220V.So just have equation relation: the direction of UO=U1+ △ U i.e. △ U is identical with the direction of U1, size is just 20V.As can be seen from formula above, bucking voltage △ U is responded to the low-pressure side of compensator transformer by iron core by the high-pressure side of being defeated by compensator transformer by voltage regulating transformer again, then carries out superposing of vector with input voltage.The transmission of compensator transformer primary responsibility bucking voltage, voltage regulating transformer is then responsible for provider to the bucking voltage that can change with size.

As can be seen from Figure 1, C, D point of lifting device is connected across on 220V voltage.And E point is just the central point of voltage regulating transformer 1.We suppose that cursor slide is parked in C point, the on high-tension side voltage being so added in compensator transformer 2 be F point higher than G point, electric current flows to G point by F point.

When cursor slide is parked in D point, as shown in Figure 2, be added in the on high-tension side voltage of compensator transformer be G point higher than F point, electric current flows to F point by G point.So, the bucking voltage adding to compensator transformer just changes direction.It is that the voltage obtained at high-pressure side F point and the G point of compensator transformer is higher, otherwise lower when cursor slide is from the central point E of voltage regulating transformer that voltage regulating transformer changes the size of bucking voltage.When the input voltage of pressurizer is just 220V, when cursor slide moves on to E point, the bucking voltage between F point and G point is just 0.The downside of compensator transformer is neither added and does not also subtract each other, and output voltage is exactly input voltage size.

The technical program adopts master controller to control the amplitude of electric machine rotation in real time and the time realizes Intelligent adjustment function, voltage regulation limits can be increased and realize intelligent voltage stepless control, booster tension regulates precision greatly, effectively solves traditional reactive power compensator voltage-regulation blind area.

Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
