Fig. 2 is the another kind of elementary diagram of high-tension coil of the machine body structure of a kind of dual voltage amorphous alloy iron core oil-immersed distribution transformer of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
As shown in Figure 1 and Figure 2, the present invention, it is a kind of machine body structure of dual voltage amorphous alloy iron core oil-immersed distribution transformer, comprise iron core (not shown), low-voltage coil (not shown), high-tension coil 1, wherein high-tension coil 1 is provided with by the mode that the voltage that can accept two kinds of electric pressures and two kinds of electric pressures satisfy the twice relation.
In the utility model, aforesaid way is: high-tension coil 1 is divided into the coil body 11 of two sections axial or radial layouts, and every section coil body 11 two ends are respectively equipped with a tap and lift one's head 12, uses for pressure regulation.
The tap of two sections coil body 11 is lifted one's head and 12 is connected with a series parallel switch (not shown) simultaneously, and can implement the serial or parallel connection of two sections coil body 11 by regulating this series parallel switch in that the fuel tank of amorphous alloy iron core oil-immersed distribution transformer is outside.Two sections coil body 11 around to unanimity.
Operation principle of the present invention is as follows: the tap of supposing two sections coil body 11 is lifted one's head to start in 12 and is respectively A1 and A2, receives head and is respectively X1 and X2.As shown in Figure 1, when regulating this series parallel switch, make and receive an X1 and the A2 connection of starting, i.e. during two sections coil body 11 series connection, amorphous alloy iron core oil-immersed distribution transformer can satisfy the voltage of accepting a kind of electric pressure; As shown in Figure 2, when regulating this series parallel switch, make start A1 and A2, a receipts X1 and X2 connection, i.e. during two sections coil body 11 parallel connections, amorphous alloy iron core oil-immersed distribution transformer can satisfy a half voltage of accepting preceding a kind of electric pressure.
The present invention both can be applicable to single-phase amorphous alloy iron core oil-immersed distribution transformer, can be applicable to the three-phase amorphous alloy iron core oil-immersed distribution transformer again.
In sum, the present invention is by dividing two sections with high-tension coil integral body, be connected in series or parallel, make the high-tension coil of amorphous alloy iron core oil-immersed distribution transformer can accept the voltage of two kinds of electric pressures, and these two kinds of voltages satisfy the twice relation, have satisfied the requirement of two electric pressures of distribution line.
Below embodiment has been described in detail the present invention in conjunction with the accompanying drawings, and those skilled in the art can make the many variations example to the present invention according to the above description.Thereby some details among the embodiment should not constitute limitation of the invention, and the scope that the present invention will define with appended claims is as protection scope of the present invention.
