Abstract
The utility model relates to a separated three-phase power transformer, which belongs to the transformer technical field. The utility model comprises a primary input coil, three secondary output coils, and irons which are arranged among the secondary coils. The combination of the primary input coil and the three secondary output coils ensures that the transformer can output three different voltages according to needs. The transformer can output voltages of three different shifts according to the requirements of actual utilized voltage, and required voltage also can be achieved according to the changes of grid voltage through the transformer.
Description
Technical field
The utility model belongs to a kind of isolated three phase mains transformer, and it can realize three different voltages with secondary output by elementary input.
Technical background
Transformer is a kind of by elementary input, by what of the inside institute coiling, at the different voltage of secondary output.Transformer is of many uses, can obtain different voltage by transformer according to the needs of required voltage.Thereby the changing value that how to improve the transformer output voltage increases the output gear in other words and has become research and development problem in the sector.
Summary of the invention
The utility model purpose is to provide a kind of isolated three phase mains transformer, and it has three output gears, to adapt to the demand of different output voltages.
For achieving the above object, the technical scheme that the utility model adopted is: a kind of isolated three phase mains transformer is characterized in that comprising an elementary input coil, three secondary output windings and place therebetween iron core.
After the utility model adopted technique scheme, its advantage is: when elementary input was connected on the elementary input coil, three secondary output windings were exported three different voltages respectively as requested.Thereby make transformer can export three different voltages as required, be the voltage that transformer can be exported three different gears, can realize by this transformer according to the requirement of actual utilization voltage, also can reasonably adjust required voltage by this transformer according to the variation of line voltage.
