Description
Technical field
The present invention relates to a kind of amorphous alloy transformer, specifically design a kind of Adjustable Capacity amorphous alloy transformer.
Background technology
Known to Fig. 1, shown in Figure 2; The core construction of present amorphous alloy transformer all is the core construction of single frame formula; The unique physical restriction of the amorphous alloy material that chase uses; The iron core of non-crystaline amorphous metal can only manufacture therefore the square-section has also formed a kind of rectangle on the allocation problem of winding winding form, and the amorphous alloy transformer capacity is fixed at present.
Square-section and capacity are that fixed form has following shortcoming:
One, rectangle winding problem
Known, the core construction of present amorphous alloy transformer all is the core construction of single frame formula, the unique physical architectural characteristic restriction of the amorphous alloy material that chase uses, and the iron core of non-crystaline amorphous metal can only manufacture the square-section; Therefore on the allocation problem of winding, also formed a kind of winding form of rectangle, and the amorphous alloy transformer capacity is fixed at present.
