Abstract
The utility model relates to an amorphous alloy iron core for a distributed tower head, which comprises an outer silicon steel plate, an inner short silicon steel plate, amorphous alloy bands and an inner long silicon steel plate; the inner short silicon steel plate and the inner long silicon steel plate are lapped into an inner layer, at least three band sleeves composed of amorphous alloy bands are arranged between the inner and the outer silicon steel plates; the amorphous alloy iron core is characterized in that the group numbers of each group of amorphous alloy bands are increased by 0 to 1 group compared with the former, the lapping heads of each group of amorphous alloy bands are staggered, and included angles formed by connecting wires at the tail ends of the lapping heads at both ends thereof and the horizontal direction are 30 to 60 degrees. The amorphous alloy iron core has the advantages that no-load loss of the iron core is lower and the no-load current is smaller; the dimension in the lapping position is 1.18 times of that in the column position, thereby reducing the dimension of the transformer, and achieving the saving purpose.
Description
Technical field
The utility model relates to a kind of amorphous alloy iron core of distributed joining seam, is applied to the magnetic circuit component of power transformer, belongs to the power transformer technical field.
Background technology
The joining seam structure of traditional amorphous alloy iron core as shown in Figure 1, be by outer silicon steel sheet 1, the short silicon steel sheet 2 of nexine, amorphous alloy strips 3, the long silicon steel sheet 4 of nexine is formed, short silicon steel sheet 2 of nexine and the long silicon steel sheet 4 of nexine are overlapped to form nexine, between nexine and outer silicon steel sheet 1, be provided with the band cover that at least 3 covers are made up of amorphous alloy strips 3, the group number of every cover band is to determine according to core window width B size, the group number does not wait for from 3 to 10 groups, as: be 3 groups when 75＞B＞45, when 100＞B＞75 is 4 groups, when 125＞B＞100 is 5 groups, when 150＞B＞125 is 6 groups, 25 millimeters of the every increases of B later on, the group number increases by 1 group, maximum 10 groups, the B size of Fig. 1 is between 45 millimeters to 75 millimeters, so get 3 groups in every cover, the joining seam 5 of amorphous alloy strips 3,6, form first cover for 7 three groups, joining seam 8,9, form second cover for 10 3 groups, be arranged in order, and first joining seam of every suit, second joining seam, the 3rd joining seam all is arranged in several straight lines, the bar number of straight line is exactly the group number of every cover, and the shortcoming of this joining seam structure is:
1. the inhomogeneities of the magnetic flux distribution of whole iron core concentrates on these several the straight lines, causes iron core no-load loss and no-load current to increase, and the running noises of transformer increases;
2. iron core is bigger than normal in the size at joining seam place, and its size is 1.25 times of two edge column place sizes, makes whole iron core higher.
Summary of the invention
The purpose of this utility model provides a kind of amorphous alloy iron core of distributed joining seam, improves no-load loss, the no-load current of magnetic flux distribution with the reduction iron core, and noise of transformer; Reduce the size of iron core, dwindle the overall dimension of transformer, thereby save cost.
For realizing above purpose, the technical solution of the utility model provides a kind of amorphous alloy iron core of distributed joining seam, comprise outer silicon steel sheet, the short silicon steel sheet of nexine, amorphous alloy strips, the long silicon steel sheet of nexine, short silicon steel sheet of nexine and the long silicon steel sheet of nexine are overlapped to form nexine, between nexine and outer silicon steel sheet, be provided with the band cover that at least 3 covers are made up of amorphous alloy strips, it is characterized in that, the amorphous alloy strips group number of every suit increases the 0-1 group than last cover, the joining seam of each group amorphous alloy strips staggers, and the angle of terminal line of its two ends joining seam and horizontal direction is 30 degree-60 degree.
The group number of the utility model every suit increases than the group number of last cover, and the angle of terminal line of its two ends joining seam and horizontal direction is 30 degree-60 degree.The joining seam number of every cover increases along with the folded thick increase of iron core, and joining seam staggers, and does not concentrate on several the straight lines, makes the magnetic flux distribution of iron core more even, reduces the flux waveforms distortion.
The utility model has the advantages that iron core no-load loss is lower, no-load current is littler; The size at joining seam place is 1.18 times of two edge column place sizes, thereby can reduce the size of transformer, reaches the purpose of saving.
Description of drawings
Fig. 1 is traditional amorphous alloy iron core structural representation;
Fig. 2 is a kind of amorphous alloy iron core structural representation of distributed joining seam.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 2, be a kind of amorphous alloy iron core structural representation of distributed joining seam, the amorphous alloy iron core of described a kind of distributed joining seam is made up of outer silicon steel sheet 1, the short silicon steel sheet 2 of nexine, amorphous alloy strips 3, the long silicon steel sheet 4 of nexine.
Short silicon steel sheet 2 of nexine and the long silicon steel sheet 4 of nexine are overlapped to form nexine, between nexine and outer silicon steel sheet 1, be provided with the band cover that 3 covers are made up of amorphous alloy strips 3,3 groups of numbers of the amorphous alloy strips of every suit increase by 1 group than last cover, the joining seam 5 of amorphous alloy strips 3,6, form first cover for 7 three groups, joining seam 8,9,10 and 11 form second cover, be arranged in order, the joining seam of each group amorphous alloy strips 3 staggers, its two ends joining seam 5,8 line, joining seam 7,11 the line and the angle of horizontal direction are 45 degree, the iron core no-load loss of making like this is lower, no-load current is littler, and volume is littler.
