Detailed Description
In order to better understand the above technical solutions, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
The various embodiments provided by the embodiments of the present utility model may be combined with each other and cross-referenced without conflict, thereby extending a number of possible embodiments that may be considered disclosed and disclosed by embodiments of the present utility model.
Referring to fig. 1 to 3, the utility model discloses a special triangular three-dimensional wound core transformer for new energy, which comprises a triangular three-dimensional wound core, a low-voltage coil 3, a high-voltage coil 4, an upper clamping piece 5, a lower clamping piece 5 and an insulating cushion block 6, wherein the triangular three-dimensional wound core is formed by splicing three identical iron core frames with semicircular sections, and insulating paperboards with the thickness of 1mm are arranged between the semicircular sections of two adjacent iron core frames; each iron core frame is formed by winding seven trapezoidal amorphous alloy material strips 1 and silicon steel sheet material strips 2 alternately, a low-voltage coil 3 and a high-voltage coil 4 are sleeved on an iron core column, and the low-voltage coil 3, the high-voltage coil 4 and the iron core frame are clamped and fixed by an upper clamping piece 5, a lower clamping piece 5 and an insulating cushion block 6.
It should be noted that the number of turns of the low-voltage coil and the high-voltage coil and the effective sectional area of the iron core can be accurately calculated by computer software. The triangular three-dimensional wound iron core is formed by splicing three identical iron core frames, so that the triangular three-dimensional wound iron core structure has the advantages of equal length of a three-phase magnetic circuit, balanced magnetic flux and equal three-phase no-load current; in addition, because the silicon steel sheet iron core has small noise, the no-load current of the amorphous alloy iron core is very small, generally about one fifth of the silicon steel sheet iron core and no-load loss is about one fourth of the silicon steel sheet iron core, so that the no-load current of the iron core formed by mixing and winding the amorphous alloy material belt and the silicon steel sheet material belt is reduced by more than 50 percent, and the no-load loss is also reduced by more than 50 percent, namely, compared with the iron core made of a single material, the three-dimensional triangular iron core transformer provided by the utility model has low no-load loss and low noise and reduces the waste of electric energy.
Further, the lengths and widths of the amorphous alloy material belt 1 and the silicon steel sheet material belt 2 can be accurately calculated by a computer program, and then cut into corresponding trapezoid strips by an iron core cutting machine; the amorphous alloy material belt 1 and the silicon steel sheet material belt 2 can be alternately wound into the iron core frame by an iron core winding machine. When the triangular three-dimensional wound iron core is assembled, 3 iron core frames are arranged and erected at an angle of 60 degrees by utilizing an iron core assembling table, and insulating paperboards with the thickness of 1mm are arranged between two adjacent semicircular sections to serve as insulating pieces between the iron core frames, and the iron core columns are bound by packing belts; after the triangular three-dimensional wound iron core is assembled, annealing is carried out at a proper temperature, so that the triangular three-dimensional wound iron core reaches an optimal magnetic conduction state, then a low-voltage coil and a high-voltage coil are wound on an iron core column by special winding equipment, and finally an upper clamping piece 5, a lower clamping piece 5 and an insulating cushion block 6 are assembled, so that the triangular three-dimensional wound iron core power transformer disclosed by the utility model can be obtained.
