Embodiment
Below in conjunction with Figure of description the utility model is further elaborated.
The utility model is to be pressed with the voltage adjustment of on-load autotransformer in a kind of two device bodies that the voltage regulation coil tap number of turn can be set arbitrarily.It is made up of two device bodies, and main device body (as shown in Figure 1) is provided with low-voltage coil, high-tension coil, intermediate voltage winding and voltage regulation coil, and independent device body (as shown in Figure 2) is provided with pressure regulation feedback coil and pressure regulation magnetizing coil.
The utility model is to press in traditional single device body on the design basis of regulating autotransformer, the voltage regulation coil of main device body is provided with separately, there be not getting in touch of electricity with intermediate voltage winding, has only the contact of magnetic, be connected on the another one independence device body pressure regulation magnetizing coil of (back claims " little device body ") by parallel way simultaneously, little device also is provided with a pressure regulation feedback coil on one's body, and the pressure regulation feedback coil is connected with intermediate voltage winding, getting in touch of electricity is arranged and do not have getting in touch of magnetic with intermediate voltage winding.
As shown in Figure 3, operation principle of the present utility model is as follows: voltage regulation coil and high-tension coil, intermediate voltage winding are enclosed within on the core limb, the constant then circle of main flux electromotive force is constant, so can change voltage regulation coil voltage by changing the voltage regulation coil number of turn, the pressure regulation magnetizing coil is in parallel with voltage regulation coil, so pressure regulation magnetizing coil voltage also changes thereupon, pass through electromagnetic induction principle, because pressure regulation magnetizing coil and pressure regulation feedback coil are enclosed within on the core limb, so pressure regulation feedback coil voltage also changes thereupon.Otherwise, if when the no-load voltage ratio of pressure regulation magnetizing coil and pressure regulation feedback coil is increased, just can increase the number of turn of pressure regulation magnetizing coil, thereby increase the voltage of pressure regulation magnetizing coil, increase the voltage of voltage regulation coil simultaneously, because principal post circle electromotive force is constant, just can increases the number of turn of voltage regulation coil, thereby realize increasing every grade of number of turn of voltage regulation coil.
During concrete operations, on load tap changer is connected on the voltage regulation coil, changes the voltage of voltage regulation coil, also changed the voltage of pressure regulation magnetizing coil simultaneously by the number of turn of regulating voltage regulation coil, change pressure regulation feedback coil voltage by electromagnetic induction again, thereby the middle piezoelectricity that changes main device body is pressed.Because pressure regulation feedback coil and pressure regulation magnetizing coil are placed on separately on one's body the little device, so the no-load voltage ratio of pressure regulation feedback coil and pressure regulation magnetizing coil can be set arbitrarily, when needs increase the voltage regulation coil number of turn, just the no-load voltage ratio with pressure regulation magnetizing coil and pressure regulation feedback coil increases, so also with regard to covert increase the voltage of voltage regulation coil, also just can reach the purpose that increases every grade of number of turn of voltage regulation coil.
The utility model is by pressing in traditional single device body on the design basis of regulating autotransformer, voltage regulation coil LTC is arranged on separately on one's body the main device, be that voltage regulation coil LTC and main other coil of device body do not have getting in touch of electricity, the contact (see figure 3) of having only magnetic, little device body pressure regulation feedback coil TV and main device body intermediate voltage winding have getting in touch of electricity and do not have getting in touch of magnetic, little device body pressure regulation magnetizing coil JC is in parallel with main device body voltage regulation coil LTC, can increase every grade of number of turn of main device body voltage regulation coil LTC so arbitrarily, change the voltage of little device body voltage regulation coil TV by the no-load voltage ratio of little device body, solved because the very few problem that causes the design of transformer difficulty of the voltage regulation coil number of turn.
