Abstract

The utility model discloses a kind of ore deposit machine special utility transformer, it mainly improves the multistage positive D shape yoke cross section that adopts unshakable in one's determination, and core limb adopts Long Circle structure; The Pyatyi seam sheet mode that adopts unshakable in one's determination; Coil adopts the Long Circle structure identical with core limb.By the improvement of structure, compare with original same size product structure, can reduce no-load loss more than 10%, reduce no-load current more than 30%, reduce noise more than 10 decibels, average cost-saving 20%, energy-saving material-saving, reduces costs.

Description

A kind of ore deposit machine special utility transformer

Technical field

The utility model relates to a kind of distribution transformer, is specifically related to a kind of ore deposit machine special utility transformer.

Background technology

Original distribution transformer cores post, yoke unshakable in one's determination is multi-stage circular core section, three grades of seam laminations, coil is circular configuration, yoke unshakable in one's determination passes through core insulation coil pressing in window, because yoke unshakable in one's determination is Step Circular structure, coil and yoke compression area unshakable in one's determination are less, reduce noise and no-load loss and must in Electromagnetic Design, reduce magnetic flux density, the trade mark grade that improves silicon steel sheet, circular coil consumptive material is correspondingly also larger, will reduce noise in a word, reduce no-load loss, cost will improve a lot.

Summary of the invention

The purpose of this utility model is that a kind of distribution transformer that reduces noise, reduction no-load loss, saves material is provided for above-mentioned deficiency.

The utility model solves the technical scheme that its technical problem adopts: described a kind of ore deposit machine special utility transformer consists of unshakable in one's determination and coil, it is characterized in that: described iron core adopts multistage positive D shape yoke cross section, core limb adopts Long Circle structure, shortened centre-to-centre spacing unshakable in one's determination, in window unshakable in one's determination, the wide yoke of all level sheets portion is concordant, yoke portion can be by core insulation Large-Area-Uniform ground stretching coil, increase the anti-short circuit capability of coil, core limb length also shortens relatively, iron core weight reduces, and reaches the effect that reduces no-load loss and energy-saving material-saving; The Pyatyi lamination seam mode that adopts unshakable in one's determination can reduce no-load loss and reduce by a relatively large margin no-load current in original structure, reduces noise; Coil adopts the Long Circle structure identical with core limb, has increased effective area unshakable in one's determination, and core limb and coil reach support evenly, closely.

The utility model has the advantages that:

1., iron core adopts multistage positive D shape yoke cross section, core limb employing Long Circle structure;

2., the Pyatyi lamination seam mode that adopts unshakable in one's determination;

3., coil adopts the Long Circle structure identical with core limb.

By the improvement of above new construction, the technical program is compared with background technology, can reduce no-load loss more than 10%, reduce no-load current more than 30%, reduce noise more than 10 decibels, average cost-saving 20%, energy-saving material-saving, reduces costs, and this scheme is used in effect same on dry-type transformer.

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Accompanying drawing explanation

Fig. 1 is the utility model core construction sketch;

Fig. 2 is that Fig. 1 is along A-A line diagrammatic sectional view;

Fig. 3 is that Fig. 1 is along B-B line diagrammatic sectional view;

Fig. 4 is the zoomed-in view of I in Fig. 1.

Embodiment

Embodiment of the present utility model is described with reference to the accompanying drawings.

As shown in Figure 1, take distribution transformer cores as example, frame is opened iron core and is formed by silicon steel sheet stack.Wherein each shaped as frame is by trapezoidal 1 of left and right side column, 2, trapezoidal 3 of upper and lower yoke Intermediate Gray right angle wedge angle, 4 and middle two ends be that middle column sheet 5 stacks of 90 degree wedge angles form.

As shown in Figure 2, iron yoke adopts multistage positive D shape yoke cross section, has reduced angle and has weighed, and iron core is superposeed by eight kinds of sheet shapes.

As shown in Figure 3, core limb adopts Long Circle structure, and coil adopts the Long Circle structure identical with core limb, has increased effective area unshakable in one's determination, and core limb and coil reach support evenly, closely.

As shown in Figure 4, be the enlarged drawing of position, angle unshakable in one's determination, stairstepping Pyatyi lamination Jie Seams is respectively one-level 6,7, three grade 8 of secondary, level Four 9, Pyatyi 10.

Above are only embodiment of the present utility model; but design concept of the present utility model is not limited to this; allly utilize this design to carry out the change of unsubstantiality to the utility model, or use on other kind transformer and apply, all should belong to the row of invading the utility model protection range.

Claims

1. an ore deposit machine special utility transformer, mainly transforms iron core and the coil of distribution transformer, it is characterized in that: described iron core adopts multistage positive D shape yoke cross section, and core limb adopts Long Circle structure, and in window unshakable in one's determination, the wide yoke of all level sheets portions are concordant.

2. a kind of ore deposit as claimed in claim 1 machine special utility transformer, is characterized in that: described iron core adopts Pyatyi mulberry sheet seam mode.

3. a kind of ore deposit as claimed in claim 1 machine special utility transformer, is characterized in that: described coil adopts the Long Circle structure identical with core limb.
