The wide-range alternating-current voltage stabilize comprises three power transformers, namely a compensating transformer T1, a boosting transformer T2 and a regulating transformer T3; a live line L of an input voltage passes through one end of the secondary side of the compensating transformer T1, the other end of the secondary side of the compensating transformer T1 is connected to one end of the regulating transformer T3 and also connected to a middle fixed tap of the boosting transformer T2, and the highest voltage end of the boosting transformer T2 is connected to an output live fire terminal; an input null line N is connected with the other end of the regulating transformer T3 and the other end of the boosting transformer T2 and serves as a working null line of the regulating transformer T3, the boosting transformer T2 and the complete machine; the two ends of the primary side of the compensating transformer T1 are connected to carbon brushes, respectively, the compensating voltage delta U of the secondary side is regulated by changing different positions of the carbon brushes on the regulating transformer T3 so that the first stage of voltage stabilized output U' is realized, and after the first stage of voltage stabilized output, the voltage is further boosted and stabilized by virtue of the boosting transformer T2 to a desired output voltage value.
Description
Technical field
The utility model relates to a kind of voltage stabilizer, especially refers to a kind of AC voltage regulator of input voltage wide region.
Background technology
The most conventional AC voltage regulator has two kinds of working methods at present, is respectively compensated voltage regulator and autocoupling type voltage stabilizer.Wherein compensated voltage regulator by changing the size and Orientation of bucking voltage on compensator transformer, increases or reduces corresponding voltage on the basis of input voltage, reaches voltage stabilizing output.What autocoupling type voltage stabilizer adopted is to change the diverse location of input voltage at autotransformer, and output voltage, in a certain fixed position, reaches voltage stabilizing output by changing the turn ratio of input voltage and output voltage.But can't finely meet the wide region voltage stabilizing demand of this deflection low pressure according to existing voltage regulation way on market, as realize input voltage range 100V-260V, voltage stabilizing output 220V, if while adopting compensation voltage regulation way to realize wide region voltage stabilizing, due to the symmetry of compensation high-low pressure, need to compensate 120V voltage stabilizing output 220V at low side 100V, the voltage stabilizing value of high-end maximum can reach 340V, and waste appears in voltage stabilized range 260V-340V; If adopt autocoupling type voltage regulation way expense larger, and band carries work in the situation that of low pressure 100V, realize voltage stabilizing to 220V, larger to the power requirement of transformer, current existing voltage stabilizing working method is difficult to realize full power band and carries the requirement of work, so can not meet the wide region voltage stabilizing demand of this deflection one end well.
Summary of the invention
The purpose of this utility model is to provide a kind of AC voltage regulator of wide region.

By regulating carbon brush to change the bucking voltage value of T1 at the diverse location of T3 plane, change bucking voltage value △ U, obtain first order voltage stabilizing output U '=Ui ± △ U, U ' after first order voltage stabilizing boosts by step-up transformer T2, adopt the ratio realization of autotransformer input number of turn n1 and output number of turn n2 to boost, final voltage stabilizing output Uo=n2/n1*U '.If bucking voltage scope is 80V, first order voltage stabilizing output valve is 180V, by the step-up transformer 40V that boosts, and final voltage stabilizing output 220V, when design load meets input voltage range 100V-260V, output voltage is 220V.Adopt the design's principle, can adjust according to practical application the bucking voltage scope of compensator transformer T1, if compensation range can be 20V-100V, first order output voltage U ' can be within the scope of 160V-200V, the voltage of step-up transformer T2 is set again, if boost value is within the scope of 20V-60V according to practical application.
