Description
Technical field
The utility model relates to a kind of self coupling and becomes device, belongs to electric equipment.
Background technology
Existing self coupling becomes device as high-tension transformer, is generally used in high voltage power transmission or business electrical by high voltage variable low pressure, because its volume is little, capacity large, saves material, and welcome.The performance of autotransformer and the high prerequisite of efficiency comparison are K < 2, but the capacity of the transformer dispatched from the factory and demand capacity when having a difference, cause the service efficiency of electric energy in use procedure low, and magnitude of voltage has deviation, the enterprise that affects to a certain degree produces.In the transformer of rated capacity, autotransformer is gently won with the little quality of its volume, and when the technology maturation of current two winding transformer, the volume of two winding transformer also reduces a lot, can reach and maintain an equal level with the volume of existing autotransformer and quality.In order to adapt to the development of autotransformer, we be badly in need of a kind of can pondage and the little autotransformer of volume.
Summary of the invention
In view of above-mentioned prior art is not enough, the utility model aim to provide a kind of volume little, can pondage autotransformer.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of autotransformer, and comprise the coil that iron core in housing, housing and iron core are wound with, coil is divided into primary coil and secondary coil; Described iron core is cylindrical screw line style; Housing has vertical axisymmetric first chute and the second chute, coil is the first peak point near the point of the first chute, and coil is the second peak point near the point of the second chute, and the first peak point and the second peak point are exposed point; Be provided with the first slip terminal of conflicting with the first peak point in first chute, in the second chute, be provided with the second slip terminal of conflicting with the second peak point; Form primary coil between the A end of coil and the first slip terminal, coil B holds and form secondary coil between the second slip terminal.
Further, described second slip terminal or coil B hold and are connected with earth leakage circuit-breaker.Prevent the zero line break of primary coil, the live wire of primary coil is directly connected with the wire of secondary coil, causes electric leakage accident.Also have on secondary coil and open circuit occurs, also can form secondary coil and be connected with the live wire of primary coil electric leakage accident occurs.
The beneficial effects of the utility model:
Compared with conventional art, the iron core of the utility model autotransformer is cylindrical screw line style, and in the transformer of rated capacity, volume of the present utility model is less, is easy to carry and installation.First, second slip terminal of the present utility model can slide between the first peak point corresponding with it on its chute and the second peak point, realizes the object of the capacity regulating transformer; The number of turn of the coil between the exposed point on the first peak point or the second peak point is identical, can realize regulating according to a certain percentage, handle simple and convenient.
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.
As shown in Figure 1, a kind of autotransformer, comprise the coil that iron core 2 in housing 1, housing 1 and iron core 2 are wound with, coil is divided into primary coil 3 and secondary coil 4; Described iron core 2 is cylindrical screw line style; Housing 1 has vertical axisymmetric first chute 5 and the second chute 6, coil is the first peak point 7 near the point of the first chute 5, and coil is the second peak point 8, first peak point 7 and the second peak point 8 near the point of the second chute 6 is exposed point; Be provided with in first chute 5 in first slip terminal 9, second chute 6 of conflicting with the first peak point 7 and be provided with the second slip terminal 10 of conflicting with the second peak point 8; Form primary coil 3 between the A end 11 of coil and the first slip terminal 9, between coil B end 12 and the second slip terminal 12, form secondary coil 4.
The iron core 2 of the autotransformer of this example is cylindrical screw line style, and in the transformer of rated capacity, volume of the present utility model is less, is easy to carry and installation.First slip terminal 9, second slip terminal 10 can slide between the first peak point 7 corresponding with it on its chute and the second peak point 8, realizes the object of the capacity regulating transformer;
The number of turn of the coil between the exposed point on first peak point 7 of this example or the second peak point 8 is identical, can realize regulating according to a certain percentage, handle simple and convenient.
Further, described second slip terminal 10 or coil B hold on 12 and are connected with earth leakage circuit-breaker 13.Prevent the zero line break of primary coil 3, the live wire of primary coil 3 is directly connected with the wire of secondary coil 4, causes electric leakage accident.Also have on secondary coil 4 and open circuit occurs, also can form secondary coil 4 and be connected with the live wire of primary coil 3 electric leakage accident occurs.
