The iron core mutual inductor provided by the utility model has the characteristics of high filling coefficient, little magnetic flux leakage, low loss and low temperature rise, and is favorable for improving the using performance of the mutual inductor, miniaturizing the product, saving energy and reducing consumption.
Description
Technical field
The utility model relates to electronic device field, relates in particular to a kind of instrument transformer.
Background technology
Transformer iron core is the important component part of instrument transformer; The good and bad serviceability that directly influences instrument transformer of its performance, traditional transformer iron core adopts silicon steel sheet to roll into the notch cuttype iron core, exists activity coefficient little; It is big to take up room; Leakage field is big, the iron circuit loss is high, the shortcoming of temperature rise, has seriously restricted the performance of instrument transformer and the popularization of application, is unfavorable for that the product miniaturization is with energy-saving and cost-reducing.
The utility model content
The purpose of the utility model is to provide a kind of iron core instrument transformer, to solve the problems of the technologies described above.
The technical problem that the utility model solved can adopt following technical scheme to realize:
A kind of iron core instrument transformer comprises a current transformer body, it is characterized in that, said current transformer body comprises iron core, the port type iron core that said iron core adopts the silicon strip coiling to form, and the cross section of said iron core is circle or elliptic cross-section.
The iron core that said iron core adopts the coiling of a continuous silicone steel band to form, said iron core launched tiling from outmost turns to inner lane after, said silicon strip for from left to right by narrow chap again by a continuous silicone steel band that slightly narrows down.
Slick and sly curve is adopted on the both sides up and down of said silicon strip, opens material through the curve cutting machine and obtains said silicon strip, forms the silicon strip of lower curve symmetry on, the core section of being convenient to turn to be circular cross-section and range upon range of after the edge slick and sly.
The core section of the utility model instrument transformer is a circular cross-section, and does not have the cutting end face in the magnetic circuit, so the iron core surrounding magnetic field is evenly distributed, makes that the leakage field of instrument transformer is minimum.And because under the long-pending situation of same cross-sectional, the girth of line bag shortens, the copper resistance reduces, and adds upper core and does not need cutting, and the iron circuit loss is low, temperature rise is low.The noise that produces because of magnetic circuit is discontinuous can not appear simultaneously.
Said iron core is soaked with epoxy resin, makes between lamination to fix, and strengthens mechanical strength.
The diameter range of the circular cross-section of said iron core is 45mm-75mm.
The thickness of said silicon strip is between the 0.23-0.27mm.
Beneficial effect: owing to adopt technique scheme, it is big to the utlity model has activity coefficient, the characteristics that leakage field is little, loss is low, temperature rise is low, noise is little, and the serviceability that helps improving instrument transformer is with the product miniaturization and save energy and reduce the cost.

Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand with effect and understand, below in conjunction with the further elaboration the utility model of concrete diagram.
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of iron core instrument transformer comprises a current transformer body; Current transformer body comprises iron core 2; The port type iron core 2 that iron core 2 adopts silicon strip 21 coilings to form, iron core 2 adopts the iron core 2 that 21 coilings of continuous silicone steel band form, with reference to Fig. 3; After iron core 2 launched tiling from outmost turns to inner lane, silicon strip 21 for from left to right by narrow chap again by a continuous silicone steel band 21 that slightly narrows down.Silicon strip adopts slick and sly curve in both sides about in the of 21, drives the silicon strip 21 that material obtains lower curve symmetry on through the curve cutting machine, iron core 2 cross sections of being convenient to turn to be circular cross-section and range upon range of after the edge slick and sly.
With reference to Fig. 2, the cross section of iron core 2 is the cross section of sub-circular.
The diameter range of the circular cross-section of iron core 2 is 45mm-75mm.
The thickness of silicon strip 21 is between the 0.23-0.27mm.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection range to be defined by appending claims and equivalent thereof.
