Abstract
The utility model relates to a combined coiled iron core three-phase transformer. The surface of an iron core of an original three-phase transformer is arranged in a star type mode. The iron core is in an overlap type or is wound in a ploygon mode. An improved design adopts three coiled iron core frames with same shapes and semicircular sections to be combined into a three-phase iron core. Iron core columns are arranged in a stereo triangle. Magnetic circuits of three phases are completely symmetrical. The magnetic circuits are short. The section of the iron core is circular. The iron core has no joints and has small magnetic resistance. The transformer has the advantages of small size, less material consumption, small noise, exciting current reduction and no-load loss reduction. The utility model is a low loss transformer which has the advantages of stable performance, high efficiency and energy saving.
Description
The utility model relates to a kind of confession, power consumption equipment, specifically a kind of composite type volume iron core three-phase transformer.It is with three similar shape semi-circular sections volume iron core frames, is combined into the three-phase transformer iron core, makes three-phase magnetic circuit symmetry fully, and iron core does not have to connect and meets, and volume is little, and loss is low, and is efficient, energy-conservation a kind of three-phase transformer.
At present, known three-phase transformer iron core mostly is the plane
Type is arranged, and iron core is stacked or polygon is reeled, and three-phase magnetic circuit is unbalanced, and the iron core column activity coefficient is low, and volume is big; Minority delta arrangement involute formula Wound core transformer owing to have planed joint between iron core column and upper and lower conductive magnetic yoke, causes performance to reduce greatly.
The purpose of this utility model is exactly to provide a kind of only to combine with three similar shape semi-circular section volume iron core frames in order to overcome weak point of the prior art.And make tri-phase iron core magnetic circuit symmetry fully, the stem stem cross section be circular, and iron core does not have seam, causes magnetic resistance to reduce greatly, makes that it becomes that exciting curent is little, no-load loss is low, volume compact, noise composite type little, stable work in work roll up the iron core three-phase transformer.
The purpose of this utility model is achieved in that a kind of three-phase transformer that improves core design on the basis of original three-phase transformer, it is the semi-circular section iron core column frame that is formed by magnetic conduction band continuous reeling with three, be combined into the three-phase transformer iron core, its stem stem is three-dimensional delta arrangement, every iron core column is divided two halves, is formed by the continuous coiling of same magnetic conduction band with second half of adjacent iron core column respectively.Its magnetic conduction strip width changes with length, can draw as calculated according to the concrete size of iron core.Assembling iron core is behind annealing in process and colligation dipping, with special-purpose reel iron core transformer coil winding device coiling, final assembly.
Owing to adopt such scheme, make three-phase transformer magnetic circuit symmetry fully, magnetic circuit shortens, core section is circular, and iron core does not have to connect and meets, and iron core magnetic resistance reduces greatly, volume compact, save material, the exciting curent and the no-load loss of its transformer reduce greatly, are a kind of function admirable, energy-efficient, low-loss transformer.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1, Fig. 2 are the front view and the vertical views of the utility model composite type volume iron core three-phase transformer iron core, and a semi-circular section volume iron core frame is and analyses and observe shape in the vertical view 2.
Fig. 3, Fig. 4, Fig. 5 are front view, A-A cutaway view, the B-B cutaway views of the utility model embodiment semi-circular section volume iron core frame.
Capacity and empirical equation according to the composite type volume iron core three-phase transformer that will make
(D: iron core column diameter; S
Post: every column capacity; K: empirical coefficient), calculate the required sectional dimension of iron core column; Choose suitable magnetic flux density according to the performance of employing magnetic conduction band and can draw every circle coil voltage number; Calculate the number of turn of transformer high-voltage coil and low-voltage coil; According to the size of high and low pressure nominal load current and the load loss of permission, choose suitable high and low pressure winding wire sectional area, again according to requirements such as insulation and heat radiations, calculate the window width and the window height of iron core, draw the concrete size of iron core column frame.Make the winding mould of rolling up the iron core frame by size, calculate magnetic conduction band length and width size, and the magnetic conduction band is cut into required size, on equipment for coiling iron core, be wound into single semi-circular section volume iron core frame with the controlled slitting equipment of width.Behind annealing in process and colligation dipping, with general assembly behind the special-purpose reel iron core transformer coil winding device coiling.
