Abstract
The utility model relates to the technical field of design and manufacturing of current transformers, and discloses a cylindrical amorphous alloy current transformer iron core structure. An amorphous alloy current transformer iron core is of a step-shaped cylindrical structure and is composed of a high magnetic conductive pull board and three kinds of amorphous alloy strips, and the widths of the three kinds of amorphous alloy strips are 213 mm, 170mm and 142mm respectively. As for the main stage of the cylindrical iron core, the pull board is made of high magnetic conductive material, and a first-stage iron core is added in a virtual mode; and the amorphous alloy strips with the widths of 213mm, 170mm and 142mm are successively and symmetrically distributed on two sides of the main stage of the cylindrical iron core. The high magnetic conductive pull board and the three kinds of amorphous alloy strips are combined according to a certain proportion to enable the section of the iron core to be in a step round shape. The cylindrical amorphous alloy current transformer iron core structure is mainly applied to a middle-high-voltage electrical power system.
Description
Technical field
The utility model discloses a kind of cylindrical amorphous alloy transformer iron core structure, belong to design of transformer manufacturing technology field.
Background technology
Non-crystaline amorphous metal is main material to be dissolved mutually (wherein boron, iron, nickel, silicon and carbon etc. are main the selection of material), under the liquid condition after dissolving, speed cooling rapidly with 106K/s is gone down, after cooling, be sheet metal from alloy liquid form once-forming, and its solid-state alloy does not have lattice and this existence of two kinds of crystal boundary; So such alloy also just is referred to as amorphous alloy.Amorphous alloy strips does not have lattice and crystal boundary to exist, and its magnetizing power is very little, and has good temperature stability.
At field transformer, non-crystaline amorphous metal has many special performance characteristics as a kind of novel high-tech transformer core material, as excellent magnetism, corrosion resistance, resistance to wear, high rigidity, high strength, high resistivity etc., the iron core of being made by amorphous alloy strips has high saturated magnetic induction, low-coercivity, low-loss, low exciting curent, good temperature stability, more and more coming into one's own, is one of energy-conserving product of country's popularization.
The amorphous alloy strips of import at present has only 3 kinds of width of 142mm/170mm/213mm, and core construction is three-phase and five-pole or three-phase three-column structure, and area of core section is rectangle, and Transformer Winding is the band round rectangle.Rectangle winding anti-short circuit capability is poor, and the winding technique complex process has limited the development of big capacity amorphous alloy transformer.Circular winding anti-short circuit capability is strong, and winding technique is made technology maturation (high-power transformer of silicon steel chip iron core all is circular winding), is particularly suitable for big capacity amorphous alloy transformer.The long-pending maximum in square-section have only circular cross-section long-pending 63.66%, filling rate is low, and big capacity amorphous alloy transformer cost is increased.
Summary of the invention
At above-mentioned defective and deficiency, the utility model is introduced a kind of cylindrical core structure in amorphous alloy transformer.It is big that this structure has broken through amorphous alloy transformer manufacturing process difficulty, the shortcoming that manufacturing cost is high.
The utility model proposes a kind of cylindrical amorphous alloy transformer iron core structure, its content comprises:
1. novel amorphous alloy transformer iron core, its cross section such as Fig. 1.
2. transformer core becomes the stairstepping column structure, and 3 kinds of amorphous alloy strips that are respectively 213mm, 170mm, 142mm by high magnetic conduction arm-tie and width constitute.
3. circular main unshakable in one's determination adopts high permeability material as arm-tie, and virtual increase one-level iron core improves stock utilization, and the transformer cost is reduced.
4. the amorphous alloy strips of circular main unshakable in one's determination both sides is symmetrically distributed, and is followed successively by the amorphous alloy strips that width is 213mm, 170mm, 142mm.
5. high magnetic conduction arm-tie and 3 kinds of amorphous alloy strips are combined into Step Circular according to certain ratio.
The beneficial effects of the utility model are: manufacturing cost is compared original traditional structure and is reduced 25-35%, and use cost is tradition 25%, and service time is more long, and use cost is more low, has long-term benefit; The lamination coefficient was 86% originally, can reach 95% to 97% now; The coil difficulty of processing reduces greatly, and technological operation is simple, has increased substantially workman's efficient, reduces workman's cost, increases the performance of enterprises; The product low energy consumption, anti-short circuit capability is strong, and office lowers, and specific loss can reach about 20% of common loss.
