Abstract
The utility model discloses an iron core structure for large capacity rectifier transformer, including a plurality of silicon steel sheets (2) that constitute iron core (1), its characterized in that: constitute this iron core (1) whole silicon steel sheets (2) upper portion be a straight line with one side right angle line. The utility model discloses an iron core structure changes under the little condition in structure and prototype stack -up principle, has reduced the weight of iron core and has reduced no -load loss greatly, has simple structure, the convenient characteristics of processing, suitable using widely.
Description
Technical field
The utility model relates to a kind of core structure for large capacity rectifier transformer that reduces iron core weight, reduces open circuit loss.
Background technology
Rectifier transformer is the power transformer of rectifying installation. The feature of rectifying installation is former limit input AC, and secondary is exported by exporting direct current after rectifier cell. The transformer of using as fairing 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 capacity rectifier transformer as shown in Figure 1, as seen from Figure 1, right angle, the same side line that forms whole silicon steel sheets 2 tops of this iron core 1 is about arc, right angle, the same side line that simultaneously forms whole silicon steel sheets 2 bottoms of this iron core 1 is also about arc, and the loss larger and when unloaded of iron core 1 weight of this structure is larger.
Summary of the invention
The purpose of this utility model is the problem existing for prior art, provides a kind of and reduce iron core weight, reduces the core structure for large capacity rectifier transformer of open circuit loss.
The purpose of this utility model solves by the following technical programs:
For a core structure for large capacity rectifier transformer, comprise the some silicon steel sheets that form iron core, it is characterized in that: right angle, the same side line that forms whole silicon steel sheets top of this iron core is straight line.
Form the some blocks of silicon steel sheets in front side lower to concordant of this iron core.
Lower is straight line along last piece silicon steel sheet in the silicon steel sheet of some blocks of concordant front sides to right angle, the same side line of last piece silicon steel sheet bottom that forms this iron core.
The utility model has the following advantages compared to existing technology:
The utility model is by being straight line by right angle, the same side line on whole silicon steel sheets top that forms this iron core, and form the some blocks of silicon steel sheets in front side lower to concordant of this iron core, same is straight line along last piece silicon steel sheet in the silicon steel sheet of some blocks of concordant front sides to right angle, the same side line of last piece silicon steel sheet bottom that forms this iron core at present, core structure and prototype stack principle are changed in little situation, reduce iron core weight and greatly reduced open circuit loss, and there is feature simple in structure, easy to process, suitable promoting the use of.
Brief description of the drawings
Accompanying drawing 1 is core section structural representation in prior art;
Accompanying drawing 2 is core section structural representation of the present utility model.
Wherein: 1-iron core; 2-silicon steel sheet.
Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
As shown in Figure 2: a kind of core structure for large capacity rectifier transformer, comprise the some silicon steel sheets 2 that form iron core 1, right angle, the same side line that forms whole silicon steel sheets 2 tops of this iron core 1 is straight line; Form some blocks of front sides silicon steel sheet 2 lower to concordant of this iron core 1, and lower be straight line along last piece silicon steel sheet 2 in some blocks of concordant front sides silicon steel sheet 2 to right angle, the same side line of last piece silicon steel sheet 2 bottoms that form this iron core 1. The iron core of above-mentioned structure changes little in the situation that in structure and prototype stack principle, has reduced iron core 1 weight and has greatly reduced open circuit loss, has feature simple in structure, easy to process, suitable promoting the use of.
Above embodiment is only explanation technological thought of the present utility model, can not limit protection domain of the present utility model with this, every technological thought according to the utility model proposes, any change of doing on technical scheme basis, within all falling into the utility model protection domain; The technology that the utility model does not relate to all can be realized by prior art.
Claims (3)
