Abstract
The utility model discloses a harmonic suppression transformer, which comprises iron cores, coils, a housing, and a filter system including harmonic suppression coils and a filter device, wherein each harmonic suppression coil is arranged between a primary coil and a secondary coil of a coil; and the filter device connected to the harmonic suppression coils comprises filter resistors, a filter inductor and a filter capacitor. The harmonic suppression transformer provided by the utility model has the advantages that the filter device and a transformer are integrated to enable that the transformer is simultaneously provided with functions of power supply and harmonic filtration, and the higher harmonic on a power grid can be effectively filtered to enable that the harmonic wave content in the power grid can reach up to the standard.
Description
Technical field
The utility model relates to a kind of transformer, and particularly a kind of harmonic wave that transformer and filter are integrated suppresses transformer.
Background technology
Existing dry type can only play transformation and buffer action usually from the cold mould transformer.Along with the extensive use of power electronic technology and increasing substantially of feeding device capacity, the harmonic wave of generation is serious day by day to the harm that power equipment and communication line etc. causes.Solved the problem that harmonic wave suppresses in the past, mainly be to adopt harmonic current to offset or electric suppressor mode that mode such as harmonic current bypass is carried out filtering, in this course, the harmonic wave coupling transformer is only as the autonomous device that harmonic current is injected electrical network, the general power supply function of transformer and harmonic function relative separation are not are not designed and developed from the overall performance of electric power system.
The utility model content
The utility model purpose: at the problems referred to above, the purpose of this utility model provides a kind of harmonic wave that transformer and filter are integrated and suppresses transformer, reaches transformation and filter effect simultaneously.
Technical scheme: a kind of harmonic wave suppresses transformer, comprise iron core, coil and housing, also comprise the filtering system of forming by harmonic wave inhibition coil and filter, described harmonic wave suppresses coil and places between the primary coil and secondary coil of described coil, and described filter is connected described harmonic wave to be suppressed on the coil.
Described filter comprises filter inductor and filtering capacitor.
In order to prevent to produce resonance on a certain harmonic wave; described filter also comprises filter resistor; described filter resistor places before described filter inductor and the described filtering capacitor, filter inductor and filtering capacitor is protected, to reach the purpose that harmonic wave suppresses.
Beneficial effect: compared with prior art, the utility model has the advantages that filter and transformer are integrated, make transformer possess power supply and harmonic wave filter function simultaneously, the online high order harmonic component of filtered electrical makes the harmonic content in the electrical network reach standard effectively.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the A-A view of Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only be used to the utility model is described and be not used in the restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present utility model.
Shown in accompanying drawing 1,2, a kind of harmonic wave suppresses transformer, comprise iron core 1, coil 2 and housing 3, also comprise the filtering system of forming by harmonic wave inhibition coil 4 and filter 5, described harmonic wave suppresses coil 4 and places between the primary coil 6 and secondary coil 7 of described coil 2, and described filter 5 is connected described harmonic wave to be suppressed on the coil 4.
The utility model has increased harmonic wave than general conventional transformer and has suppressed coil, it is converted into harmonic wave with the output of the active harmonics generator that is attached thereto and suppresses magnetic potential, offset with the load harmonic magnetic potential vector in the main transformer magnetic circuit, harmonic magnetic potential in the final assurance main transformer magnetic circuit reaches the purpose that suppresses the infiltration of the humorous wave direction primary side of main transformer load-side electrical network less than set point.Should strictly notice in the design process of harmonic wave inhibition transformer that the transmission performance index that guarantees transformer meets relevant electric power standard with harmonic wave rejection index.
