Abstract
The utility model relates to a high-leakage reactance transformer, which consists of a magnetic core, and primary coils and secondary coils wound on the magnetic core, wherein the magnetic core has a five-column structure. Main magnetism partitioning sheets constructed by high-magnetic-conduction silicon steel sheets are arranged between the input primary coils and the output secondary coils, so that independent magnetism partitioning channels are provided for input and output windings; certain gaps are reserved between the main magnetism partitioning sheets and the magnetic core, so that the magnetic resistance of the magnetism partitioning channels is increased; balanced magnetism partitioning sheets are respectively arranged between two columns on the outer side of the magnetic core, so that the three-phase leakage reactance of the transformer is balanced; and moreover, the filter inductance of a system can be adjusted directly by adjusting the thicknesses of the silicon steel sheets, therefore the high-leakage reactance transformer is convenient, economical and practical.
Description
Technical field
The utility model relates to a kind of transformer, especially a kind of high-leakage impedance transformer.
Background technology
Transformer is to utilize electromagnetic induction to change the device of alternating voltage, be commonly used for lifting voltage, matched impedance, safety isolation etc. are in electric equipment and radio-circuit, the use of power electronics can produce a large amount of harmonic waves, and this requires power supply itself to have the isolation transformation function.
The output of these inverters at present has reactor to add transformer output, reactor is used for the harmonic wave of filtering inverter, transformer is mainly isolation electrical network and equipment and changes electric power output voltage to satisfy the system voltage requirement, but this mode has increased the complexity of the installation and maintenance of equipment, and cost is also higher; Also having a kind of is transformer output, this output transformer has adopted input, output winding to separate coiling and has installed, the artificial degree of coupling that weakens input, output, utilize like this leakage impedance of transformer to come the harmonic wave of inverter, isolate simultaneously electrical network and equipment and change electric power output voltage to satisfy the system voltage requirement; But the leakage impedance of this transformer is regulated by air-gap fully, and the permeability of air is very low, and leakage impedance is just smaller like this, and filter effect is also undesirable.
The utility model content
The purpose of this utility model is to overcome the defective that prior art exists, and a kind of high-leakage impedance transformer is provided.
The technical scheme that realizes the utility model purpose is: a kind of high-leakage impedance transformer, formed by magnetic core and primary coil, secondary coil on magnetic core, and described magnetic core is five rod structures.
Further, two of the centres of described magnetic core intercolumniation is respectively equipped with main minute magnetic sheet, and two, outside intercolumniation is respectively equipped with balance and divides magnetic sheet.
Further, described magnetic core and balance are divided between magnetic sheet, main minute magnetic sheet the space.
Further, in the middle of described magnetic core, three post magnetic core tops are wound with primary coil, and the bottom is wound with secondary coil.
Further, described magnetic core, main minute magnetic sheet and balance divide magnetic sheet all to be made of the cold-reduced silicon sheet of high magnetic conduction.
The utlity model has positive effect: the master who is provided with high magnetic conduction silicon steel sheet formation between input primary coil and output secondary coil divides magnetic sheet, this provides and has independently divided magnetic channel for input, output winding, leave a fixed gap between main minute magnetic sheet and magnetic core, increased the magnetic resistance of minute magnetic channel, be provided with respectively balance at two intercolumniations in the magnetic core outside and divide magnetic sheet, so that Three-Phase Transformer leakage reactance balance, and can by regulating the filter inductance of the direct regulating system of silicon steel sheet thickness, not only facilitate but also economical and practical.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model according to specific embodiment also by reference to the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Wherein: 1, primary coil, 2, secondary coil, 3, magnetic core, 4, balance divides magnetic sheet, 5, a main minute magnetic sheet.
Embodiment
As shown in Figure 1, the utility model is a kind of high-leakage impedance transformer, and magnetic core 3 is five rod structures, is wound with primary coil 1 on magnetic core 3 tops of middle three posts, the bottom is wound with secondary coil 2.Two of the centres of magnetic core 3 intercolumniation is respectively equipped with main minute magnetic sheet 5, two intercolumniations in the outside are respectively equipped with balance and divide magnetic sheet 4, magnetic core 3 and main minute magnetic sheet 5, balance is divided between magnetic sheet 4 that the space is arranged, and magnetic core 3, balance divide magnetic sheet 4 and a main minute magnetic sheet 5 all to be made of the cold-reduced silicon sheet of high magnetic conduction.
The master who is provided with high magnetic conduction silicon steel sheet formation between input primary coil 1 and output secondary coil 2 divides magnetic sheet 5, this provides and has independently divided magnetic channel for input, output winding, leave a fixed gap between main minute magnetic sheet 5 and magnetic core 3, increased the magnetic resistance of minute magnetic channel, otherwise leakage reactance is too large, and transformer has just lost the function of itself.Owing to being three-phase structure, so after installing minute magnetic channel additional, in the middle of can causing, minute magnetic channel thickness of a phase is the twice of other two-phase, thereby cause the three-phase leakage reactance seriously uneven, divide magnetic sheet 4 so be provided with respectively balance at magnetic core two, 3 outside intercolumniation, for two-phase in addition provides extra minute magnetic channel, so that Three-Phase Transformer leakage reactance balance, and can by regulating the filter inductance of the direct regulating system of silicon steel sheet thickness, not only facilitate but also economical and practical.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
