Core or the ED shaped iron core of two each and every one C-shaped Wound cores composition, have self-shileding, a feature that leakage field is little.The shell of these traditional structures
Formula iron core is owing to power is little, the reason of window narrows fundamentally cannot be used high-power high voltage transformator.
Summary of the invention
It is an object of the invention to overcome above-mentioned weak point, thus a kind of high-power high voltage transformator that is applicable to is provided
Laminated core, improves the width of core window, can be suitably used for high-power high voltage transformator, and simple in construction is easy to process.
The technical scheme provided according to the present invention, a kind of laminated core being applicable to high-power high voltage transformator includes ferrum
Yoke, lower yoke, stacked newel, stacked left side post and stacked right side post, upper yoke and lower yoke be arranged in parallel up and down,
It is characterized in that: in the middle part of upper yoke and lower yoke, be provided with stacked newel, stacked newel upper and lower side respectively with upper yoke and
Overlap in the middle part of lower yoke；Stacked left side post and stacked right side post, lamination it is respectively arranged at two ends with about upper yoke and lower yoke
On the left of formula, the upper and lower side of post overlaps with the left side of upper yoke and lower yoke respectively, the upper and lower side of stacked right side post respectively with upper ferrum
The right side overlap joint of yoke and lower yoke.
Further, stacked newel includes multiple central lamination, multiple central lamination company of stacking gradually from the bottom up
Being connected into one, multiple central lamination upwards two ends width to become larger from centre.
Further, stacked left side post includes that multiple side lamination, multiple side lamination stack gradually from the bottom up and connect into
Integrally, multiple side lamination are the rectangular configuration of equal size；Described stacked right side post is identical with stacked left side rod structure.
Further, stacked left side post and the Surface coating pyrocondensation belt of stacked right side post.
Compared with the prior art the present invention has the advantage that
Present configuration is simple, compact, reasonable, and cylinder uses stalloy to be laminated, easy to process, is lost low；In stacked
Stem is supporting with annular Transformer Winding, owing to cylinder at the bottom of this newel ladder and winding constitutes heat radiation air flue, it is possible to increase become
The heat-sinking capability of depressor, annular Transformer Winding coiling simultaneously is convenient, and is difficult to damage wires；Pyrocondensation belt makes a stacked left side
Multiple silicon steel laminations of lateral column and stacked right side post are in close contact and do not loosen, it is to avoid the noise produced owing to loosening；Improve
The width of core window, can be suitably used for high-power high voltage transformator, and simple in construction is easy to process.
