In an embodiment of the invention, the angle between two adjacent edges of the snake-shape flat plate composing the transformer winding is 120-150 degrees, process request for manufacturing the winding is reduced, and requesats for manufacturing material of the winding, machining process and producing circumstance are low, a manufacturing cost of the transformer winding can be obviously reduced, a winding heat sink problem is overcame under a large current work circumstance. Further, a material usage rate of a whole plate for cutting the snake-shape flat plate can be improved thereby saving the material.
Description
Technical field
The invention belongs to field transformer, relate in particular to a kind of Transformer Winding and transformer.
Background technology
Transformer is the device of conversion alternating voltage, electric current and impedance.Transformer is made up of magnetic core and coil, and coil has two or more windings.Winding and magnetic core are collectively referred to as the power transformer body, are the circuit parts of setting up magnetic field and electric energy transmitting.On principle, magnetic core is the magnetic circuit that constitutes transformer, and it is converted into magnetic energy with the electric energy of primary circuit, again this magnetic energy is converted into the electric energy of secondary circuit, and therefore, magnetic core is the mediator of energy delivery.Structurally, magnetic core is the skeleton that constitutes transformer, puts the coil that has insulation on its core post, and securely they is supported and compress.
The winding of existing transformer is to pass through lead basically, for example enamelled wire forms around a magnetic core repeatedly, there is bigger technological limits, input, output current are very limited, manufactured materials, processing technology and production environment to winding are had relatively high expectations, and have increased the manufacturing cost of transformer.
Summary of the invention
The purpose of the embodiment of the invention is to provide a kind of Transformer Winding, is intended to solve the bigger technological limits of winding making existence of existing transformer, has increased the problem of manufacturing cost.
The embodiment of the invention is achieved in that a kind of Transformer Winding, and described Transformer Winding is folded to form by mirror image by snakelike flat template material, and the angular range between described snakelike flat template material two adjacent edges is 120～150 degree.
The purpose of another embodiment of the present invention is to provide a kind of transformer, comprises winding, and described winding is folded to form by mirror image by snakelike flat template material, and the scope of the angle between described snakelike flat template material two adjacent edges is 120～150 degree.
In the embodiment of the invention, angle between two adjacent edges of the snakelike flat template material of formation Transformer Winding is 120～150 degree, reduced the technological requirement that winding is made, manufactured materials, processing technology and production environment to winding require all lower, can obviously reduce the manufacturing cost of Transformer Winding, under the operational environment of big electric current, overcome the winding heat dissipation problem.Further, can improve the stock utilization of the monoblock sheet material of the snakelike flat template material of cutting, save material.

Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
In embodiments of the present invention, adopt the folding back of snakelike flat template material mirror image to form winding, the scope of the angle between snakelike flat template material two adjacent edges is 120～150 degree, has guaranteed that winding adds the stock utilization in man-hour.
Winding in the embodiment of the invention is formed by mirror image is folding by snakelike flat template material shown in Figure 1, and the winding of formation as shown in Figure 2.Snakelike flat template material is added man-hour, need cut out a plurality of snakelike flat template materials from the flat template material of monoblock, so the sheet material utilance is influencing the manufacturing cost of winding.Fig. 3 shows three kinds of different sheet material cutting situations, the sheet material utilance difference under the different situations.
In embodiments of the present invention, the computing formula of sheet material utilance is as follows:
Wherein, a is the magnetic core cross-sectional width, and b is the magnetic core cross-section lengths, and c is the width of the snakelike flat template material that forms winding, e be engineering when using winding and magnetic core between safety (technology) distance, as shown in Figure 4.
According to above-mentioned formula, work as a=b, and the angle α between snakelike flat template material two adjacent edges is 135 when spending, only need wash out the waste material of about 0.4 times of winding width, sheet material utilance maximum, if do not excise extra material, then the resistance fall of winding surpasses 25%.
Above-mentioned is the theoretical value of sheet material utilance, when engineering is used, the actual value of the angle between snakelike flat template material two adjacent edges can theoretical value ± float in 15 ° of scopes.
The embodiment of the invention has reduced the technological requirement that winding is made, manufactured materials, processing technology and production environment to winding require all lower, can obviously reduce the manufacturing cost of Transformer Winding, under the operational environment of big electric current, overcome the winding heat dissipation problem.Further, can improve the stock utilization of the monoblock sheet material of the snakelike flat template material of cutting, save material.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
