The utility model has the advantages that the voltage can be increased and reduced, the AC and DC safety low voltage can be output, the operation is convenient, and the utility model can meet the requirements of different voltages of the audiomania, the research and development personnel, the appliance maintenance departments, the construction sites, the household daily life, etc.
Description
The utility model relates to a kind of self coupling, the multi-functional transformer of mutual inductance.
Existing transformer is different according to purposes, is autotransformer or inductance transformer mostly, is mainly used in pressure regulation, boosts or step-down.Usually these transformers have fixing purposes mostly, and applicable scope has certain limitation.So far do not find a kind of multiduty transformer of the scope of application as yet.
The purpose of this utility model is to provide a kind of structure, and comparatively simple operations is convenient, but not only can boost but also step-down, and the multi-functional transformer of also exportable AC and DC low-tension supply is to satisfy many-sided needs.
The utility model is by secondary low-voltage coil of coiling again in addition on the iron core of auto-type transformer, produce low-tension supply by mutual inductance, produce low-voltage dc power supply through rectification again, thereby realize ascending, descending pressure (former self coupling coil produces), AC and DC low-tension supply.
Multi-functional transformer of the present utility model, comprise unshakable in one's determination 1, self coupling primary coil 2, tap 3, can with the contacted multicontact switch 4 of tap, it is characterized in that on unshakable in one's determination 1 in addition one group of secondary low-voltage coil 6 of coiling again, the tap 7 that is provided with on the coil 6, can be connected with bidirectional switch 9 by multicontact switch 8, bidirectional switch is connected rectifier cell 10 or is directly connected low-voltage alternating-current output (G, H)
Accompanying drawing is the structure principle schematic that connects of the present utility model, coil 2 is self coupling coils of traditional autotransformer, it is the secondary coil of output high pressure of the present utility model, and wherein that part of connection input power supply is as primary coil, and the beguine of its primary coil and the secondary coil number of turn is decided according to the requirement of output voltage.It is 310 volts that the utility model is intended the output ceiling voltage, so primary coil and the secondary coil number of turn than about 1:1.4, suitably select the quantity and the position of tap 3, linking to each other with voltage output end by multicontact switch 4 respectively gets final product 160 volts, 180 volts, 200 volts, 210 volts, 220 volts, 230 volts, 250 volts, 270 volts, 290 volts, 310 volts of output voltages, to satisfy the requirement of the different voltages of output.For the sake of security, can also and connect an autoalarm or guard member 5 that superpressure is cut off the electricity supply automatically at high-voltage output end.
Secondary low-voltage coil 6 is used for producing the output of interchange LVPS by coil 2 inductions, the number of turn of coil 6 depends on the size of the low tension that needs output and the number of turn of coil 2, and the number of turn of coil 2 and the diameter of coil depend on that then the power of voltage output reaches the specification and the magnetic flux of newly selected iron core.The coil 6 that the utility model is selected for use is 1:7-9 with the ratio of the number of turn of coil 2, and low pressure is output as between the 3-39 volt.The utility model is by multicontact switch 8, bidirectional switch 9 is directly exported 3 volts, 4.5 volts, 6 volts, 7.5 volts, 9 volts, 12 volts, 15 volts, 24 volts, 36 volts, 39 volts safe alternating voltage with the induced voltage at tap 7 places of coil 6, also can export 3 volts, 4.5 volts, 6 volts, 7.5 volts, 9 volts, 12 volts, 15 volts, 24 volts, 36 volts, 39 volts safe direct voltage by after rectifier cell 10 rectifications.
Rectifier cell can be selected dissimilar rectifier cells according to the size of the power (electric current) of required output, from powerful silicon stack until very low power rectifier diode.
Transformer of the present utility model need be used as radio, during DC power supply such as broadcast receiver, can and connect filter capacitor at dc power output end, so that eliminate AC noise.
Compare with existing transformer, multi-functional transformer of the present utility model, but both step-downs, boost, also exportable AC and DC safety low-voltage, simple in structure, extremely easy to use, can satisfy the needs of each side such as radio amateur, scientific research personnel, electric appliances service department, construction site, family daily life to different voltages, be specially adapted to charging, electric power storage (motorcycle, small and medium-sized car) and emergency lighting etc.
