Abstract
The invention discloses an iron core structure for a large-capacity rectifier transformer. The iron core structure comprises a plurality of silicon steel sheets (2) forming an iron core (1). The iron core structure is characterized in that a right-angled connection line on the same sides of the upper parts of all the silicon steel sheets (2) forming the iron core (1) is a straight line. According to the iron core structure, the weight of the iron core is reduced and the no-load loss is greatly reduced under the condition that a structure and a prototype lamination principle are slightly changed; and the iron core structure has the characteristics of simple structure and convenience for machining, thereby being popularization and application.
Description
Technical field
The present invention relates to a kind of core structure for Large Copacity rectifier transformer reducing iron core weight, reduce no-load loss.
Background technology
Rectifier transformer is the power transformer of rectifying installation.The feature of rectifying installation is former limit input AC, and secondary exports by exporting direct current after rectifier cell.Transformer as rectifying device power supply is called rectifier transformer.Industrial rectification DC power supply major part is all obtained by rectifier transformer and rectifying installation by AC network.The core section structure of existing Large Copacity rectifier transformer as shown in Figure 1, as seen from Figure 1, right angle, the same side line forming whole silicon steel sheets 2 top of this iron core 1 is about arc, right angle, the same side line simultaneously forming whole silicon steel sheets 2 bottom of this iron core 1 is also about arc, iron core 1 weight of this structure comparatively large and unloaded time loss larger.
Summary of the invention
The object of the invention is for prior art Problems existing, a kind of core structure for Large Copacity rectifier transformer reducing iron core weight, reduce no-load loss is provided.
The object of the invention is to solve by the following technical programs:
For a core structure for Large Copacity rectifier transformer, comprise the some silicon steel sheets forming iron core, it is characterized in that: right angle, the same side line forming whole silicon steel sheet tops of this iron core is straight line.
Form the lower to concordant of the some blocks of silicon steel sheets in front side of this iron core.
Lower right angle, the same side line along last block silicon steel sheet in concordant some blocks, front side silicon steel sheet to last block silicon steel sheet bottom forming this iron core is straight line.
The present invention has the following advantages compared to existing technology:
The present invention is straight line by right angle, the same side line on the whole silicon steel sheet tops that will form this iron core, and form the lower to concordant of the some blocks of silicon steel sheets in front side of this iron core, with at present along last block silicon steel sheet in concordant some blocks, front side silicon steel sheet to right angle, the same side line of last block silicon steel sheet bottom forming this iron core be straight line, when making core structure and prototype stack principle change little, reduce iron core weight and substantially reduce no-load loss, and there is structure feature simple, easy to process, be suitable for promoting the use of.
Accompanying drawing explanation
Accompanying drawing 1 is core section structural representation in prior art;
Accompanying drawing 2 is core section structural representation of the present invention.
Wherein: 1-iron core; 2-silicon steel sheet.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is further illustrated.
As shown in Figure 2: a kind of core structure for Large Copacity rectifier transformer, comprise the some silicon steel sheets 2 forming iron core 1, right angle, the same side line forming whole silicon steel sheets 2 top of this iron core 1 is straight line; Form the lower to concordant of some blocks, the front side silicon steel sheet 2 of this iron core 1, and lower right angle, the same side line along last block silicon steel sheet 2 in concordant some blocks, front side silicon steel sheet 2 to last block silicon steel sheet 2 bottom forming this iron core 1 is straight line.The iron core of above-mentioned structure, when structure and prototype stack principle change little, reduces iron core 1 weight and substantially reduces no-load loss, having the advantages that structure is simple, easy to process, is suitable for promoting the use of.
Above embodiment is only and technological thought of the present invention is described, can not limit protection scope of the present invention with this, every technological thought proposed according to the present invention, and any change that technical scheme basis is done, all falls within scope; The technology that the present invention does not relate to all is realized by prior art.
Claims (3)
1., for a core structure for Large Copacity rectifier transformer, comprise the some silicon steel sheets (2) forming iron core (1), it is characterized in that: right angle, the same side line forming whole silicon steel sheets (2) top of this iron core (1) is straight line.
2. the core structure for Large Copacity rectifier transformer according to claim 1, is characterized in that: form the lower to concordant of some blocks, front side silicon steel sheet (2) of this iron core (1).
