Description
Technical field
The utility model relates to the productions of the coils such as transformer a kind of in electric system power transmission and distribution and reactive compensation field, reactor
The core construction of product, in particular to loop product core construction.
Background technique
With society and expanding economy, low-carbon environment-friendly has become the requirement in epoch and the trend of power industry development, line
It encloses class product to develop towards high voltage, large capacity, the increase of product capacity, the core construction of loop product is also increasing, conventional
Core construction, eddy-current loss increase, high noise, and to reduce loss, conventional structure is generally used, and reduce flux density or improve silicon steel sheet
The method of grade reduces core loss, but that there are volumes is big, manufacturing cost is high, product competitiveness is low.
The big Conventional coil product core construction of industry, dresses up several grades using silicon steel sheet stack and forms, every grade of silicon steel sheet, if by
Dry monolithic be wide, isometric silicon steel sheet group is at the increasing of product capacity, every grade of silicon steel sheet width increases in iron core, area
Increase, magnetic flux leakage generates eddy-current loss with square directly proportional increase of area；Capacitance voltage leads to silicon steel sheet insulating between silicon steel sheet
Eddy Current Loss In Core of An Electromagnetic caused by layer fails and noise increase.
The conventional structure, when using for massive coil product iron core, major defect is:
1) loss is high, noise is big；
2) volume is big；
3) manufacturing cost is high.
Utility model content
The technical problem to be solved by the present invention is to provide one kind with eddy-current loss is small, light weight and cost is low, manufacture
Simple loop product core construction.
In order to achieve the above objectives, the technical solution of the utility model is as follows:
Loop product core construction, including core body, core body is by main and is symmetrically distributed in main two sides
Several secondary compositions, main is made of several main silicon steel sheet closed assemblies, and each main silicon steel sheet is identical by two structures
Left side silicon steel sheet and right side silicon steel sheet group at, between left side silicon steel sheet and right side silicon steel sheet pass through insulating layer connect.
In one embodiment of the utility model, several secondary of any side of main are diameter by big and small folded grade
Several the secondary silicon steel sheets being arranged.
In one embodiment of the utility model, primary and secondary silicon steel sheet with a thickness of 0.27mm-0.35mm.It is practical at this
In novel one embodiment, insulating layer is insulating board.
In one embodiment of the utility model, core body is round or oval.Through the above technical solutions, this
The beneficial effect of utility model is:
The utility model has many advantages, such as the small, low noise of loss, small in size, at low cost, and product competitiveness is strong.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the utility model iron core cross-sectional view.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is further described.
Shown in Figure 1, the utility model discloses loop product core constructions, are commonly used in transformer, reactance
In the loop products such as device comprising core body, core body are round or oval, and core body is by main 10 and symmetrically
Several secondary 20 for being distributed in main two sides form, and main is made of several main silicon steel sheet closed assemblies, several secondary are
By several secondary silicon steel sheets of big and small folded grade setting, each main silicon steel sheet in main is separated from the middle by two diameter
The identical left side silicon steel sheet 11 of structure and right side silicon steel sheet 12 form, by exhausted between left side silicon steel sheet 11 and right side silicon steel sheet 12
Edge layer 30 connects, and insulating layer is the insulating materials that insulating board or other insulation performances are equivalent therewith or are higher than；In this configuration,
Main is made of several main silicon steel sheet closed assemblies, and each main silicon steel sheet is by the identical left side silicon steel sheet of two structures and right side
Silicon steel sheet group at so that maximum money area of every silicon steel sheet of main reduces half, eddy-current loss reduces by 3/4, while
It solves, products with larger capacity, with the increase of silicon steel sheet area and the thickening of folded grade, the capacitance voltage of silicon steel sheet induction increases,
The problem of capacitance voltage of induction leads to the breakdown failure of silicon steel sheet insulating layer, increases Eddy Current Loss In Core of An Electromagnetic and noise, structure tool
Lossy small, low noise, small in size, at low cost, the strong technical characterstic of product competitiveness.
Primary and secondary silicon steel sheet with a thickness of 0.27mm-0.35mm.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
