Embodiment

[0047] Such as Figure 1 to Figure 9 As shown, the multi-voltage output transformer in this embodiment includes a primary coil 1210, a secondary coil 1220, an iron core 1300, and a housing 1100. The iron core 1300 includes a moving iron core 1310 and several fixed iron cores 1320. The fixed iron core 1320 is arranged around the moving iron core 1310, the moving iron core 1310 is rotatably connected to the housing 1100, the housing 1100 is provided with a rotating device 1110, and the rotating device 1110 is connected to the The moving iron core 1310 is used to drive the moving iron core 1310 to rotate. The moving iron core 1310 is in the shape of "C", and the rotation of the moving iron core 1310 can be in contact with the upper and lower ends of the fixed iron core 1320 to form Closed magnetic path; the primary coil 1210 is wound on the moving iron core 1310, and the secondary coil 1220 is wound on the fixed iron core 1320; the taps of the primary coil 1210 and the secondary ...

Abstract

The invention relates to a multi-voltage output transformer, which comprises a primary coil, a secondary coil, an iron core and a shell, and is characterized in that the iron core comprises a movableiron core and a plurality of fixed iron cores, the fixed iron cores are arranged around the movable iron core, the movable iron core is rotatably connected into the shell, a rotating device is arranged on the shell, the rotating device is connected to the movable iron core to drive the movable iron core to rotate, the movable iron core is in a C shape, and the rotation of the movable iron core canmake contact with the upper end and the lower end of the fixed iron core to form a closed magnetic path. The primary coil is wound on the movable iron core, the secondary coil is wound on the fixed iron core, and taps of the primary coil and the secondary coil extend out of the shell. The device creatively uses the annularly arranged secondary coil, the structure is more compact, more kinds of voltages are output, and the application efficiency of the magnetic flux is improved, so that the conversion efficiency of the transformer is improved.

Description

technical field [0001] The present invention relates to the field of transformers, and more specifically, the present invention relates to a multi-voltage output transformer. Background technique [0002] The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core. In order for the transformer to adapt to more applicable occasions, that is, the function of multi-voltage output, one more primary coil is used. It is implemented corresponding to multiple secondary coils. [0003] The secondary coils in the existing multi-voltage output transformers are mostly arranged side by side, that is, the iron core is usually in the shape of a "day", and the iron core wound by the secondary coil is always in the state of magnetic flux, and the taps of the secondary coil It is still unsafe to rely solely on switches such as circuit breakers, and it is very easy to ...
