Description
Technical field
The utility model relate to a kind of can the transformer of stable output voltage, specifically a kind of voltage stabilizing transformer, belongs to electric equipment.
Background technology
In some special dimensions, the use of precise electronic instrument is even more important, and the precision of precise electronic is in industry forward position all the time, meanwhile, also needs stable voltage to ensure when precise electronic instrument uses.Common transformer is when power output is constant, required precision can be ensured, once the scope of power output change greatly, the secondary voltage of common transformer has no idea automatically to regulate, cannot ensure that instrument can work normally, the precision of instrument can decline, and affects work quality, seriously may cause product rejection, for our current urgent need of the problems referred to above is a kind of can the transformer of stable output voltage.
The mode of voltage stabilizing is directly parallel with an electric capacity at load end, relies on the characteristic of the damping of electric capacity to realize voltage stabilizing, being limited in scope of this adjustment, and relevant with the frequency of change in voltage, used limitation.The thinking of the invention is that the tap of change transformer is to realize the object of voltage stabilizing.
Summary of the invention
There is provided a kind of voltage stabilizing transformer for above-mentioned technical problem, automatically can regulate the tap of the primary coil of transformer, reach the object of secondary voltage stabilizing.
For solving the problems of the technologies described above, the technical solution of the utility model is: comprise on the iron core in housing, housing and be wound with primary coil and secondary coil; Described secondary coil is also wrapped in and regulates on core, one end of core is regulated to aim at the movable terminal of primary coil, movable terminal is corresponding with the moving point position on primary coil also can slidably reciprocate thereon, movable terminal is provided with permanent magnetic iron block, and the magnetic pole of permanent magnetic iron block is put with magnetic pole opposite sex when regulating core to be energized; Be connected with compression spring between movable terminal and housing, compression spring is nested with on gag lever post.
Concrete, described moving point comprises one on primary coil and arranges exposed concave point, the fit heads of concave point and movable terminal.When movable terminal is slided, concave point well can be stuck in the head of movable terminal, and more having levels of slip can not swing because of elastic force during slip.
The beneficial effects of the utility model:
The utility model is by automatically regulating the tap of transformer to reach the object of secondary voltage stabilizing.When secondary voltage raises, regulate the magnetic flux density of core larger, regulate repulsive force between the permanent magnetic iron block in core and movable terminal larger, repulsive force is greater than the elastic force of this position compression spring, movable terminal is inwardly slided, decrease the number of turn of the primary coil of transformer, primary coil is equal to the ratio with the number of turn with the ratio of the voltage of secondary coil, and then reduces the voltage of secondary; Otherwise when secondary voltage reduces, repulsive force is less than the elastic force of this position compression spring, and movable terminal is outwards slided, and adds the number of turn of the primary coil of transformer, and then increases the voltage of secondary.
When secondary voltage raised comparatively large, movable terminal is comparatively large to slip, and the current value of primary coil is excessive, and at this moment gag lever post can block the slip of movable terminal, and the effect of gag lever post prevents the electric current in primary coil excessive and burns out primary coil.
accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
By reference to the accompanying drawings the utility model is further elaborated.
A kind of voltage stabilizing transformer, comprises on the iron core 2 in housing 1, housing 1 and is wound with primary coil 3 and secondary coil 4; Described secondary coil 4 is also wrapped in and regulates on core 5, one end of core 5 is regulated to aim at the movable terminal 6 of primary coil 3, movable terminal 6 can slidably reciprocate in the moving point 7 of primary coil 3, described moving point 7 comprises one on primary coil 3 and arranges exposed concave point, the fit heads of concave point and movable terminal 6; Movable terminal 6 is provided with permanent magnetic iron block 8, the magnetic pole of permanent magnetic iron block 8 is put with magnetic pole opposite sex when regulating core 5 to be energized; Be connected with compression spring 9 between movable terminal 5 and housing 1, compression spring 9 is nested with on gag lever post 10.
Compression spring 9 two ends connect housing 1 and movable terminal 6, and during the voltage stabilization of secondary, compression spring 9 is in pressure state, regulates the elastic force of the repulsive force between core 5 and permanent magnetic iron block 8 and compression spring 9 to hold poised state.
Concave point on primary coil 3 is corresponding with movable terminal 6, and when movable terminal 6 is slided, concave point well can be stuck in the head of movable terminal 6, and more having levels of slip can not swing because of elastic force during slip.
The present embodiment operationally, when secondary voltage raises, regulate the magnetic flux density of core 5 larger, regulate repulsive force between the permanent magnetic iron block 8 in core 5 and movable terminal 6 larger, repulsive force is greater than the elastic force of this position compression spring 9, and movable terminal 6 is inwardly slided, and decreases the number of turn of the primary coil 3 of transformer, primary coil 3 is equal to the ratio with the number of turn with the ratio of the voltage of secondary coil 4, and then reduces the voltage of secondary; Otherwise when secondary voltage reduces, repulsive force is less than the elastic force of this position compression spring 9, and movable terminal 6 is outwards slided, adds the number of turn of the primary coil 3 of transformer, and then increase the voltage of secondary.
When secondary voltage raised comparatively large, movable terminal 6 is inwardly slided comparatively large, and the current value of primary coil 3 is excessive, and at this moment gag lever post 10 can block the slip of movable terminal 6, and the effect of gag lever post 10 prevents the electric current in primary coil 3 excessive and burns out primary coil 3.
